The computers have valid IP addresses, the switch interfaces appear active, and the router is running. Yet communication still fails.

Knowing the definitions of VLANs, routers, and default gateways is helpful, but those definitions alone will not solve the problem.

The technician needs to inspect interface configurations, verify VLAN assignments, examine routing information, and identify exactly where communication breaks down.

Hands-on networking skills are becoming more important for CCNA 2027 because Cisco's updated CCNA v2.0 blueprint places greater emphasis on configuring network technologies, diagnosing connectivity failures, interpreting device output, and validating operational decisions.

The revised exam also includes more explicit coverage of IPv4 and IPv6 troubleshooting, OSPFv3, network security configuration, and AI-assisted network operations.

These changes reinforce a fundamental principle of network engineering: understanding how a technology works is different from knowing how to configure, verify, and troubleshoot it.

This guide explains seven important hands-on networking skills for CCNA 2027 and shows how they apply to real networking problems. You'll also build a complete VLAN and inter-VLAN routing lab in Cisco Packet Tracer, deliberately introduce configuration errors, troubleshoot them, and follow an eight-week practical study roadmap.

This article uses Cisco's officially published CCNA v2.0 objectives available as of November 2026. The refreshed examination is scheduled to launch on February 3, 2027.

What Is Changing in CCNA 2027?

Cisco Certified Network Associate (CCNA) validates foundational networking knowledge involving infrastructure, connectivity, switching, routing, network services, security, and operations.

Cisco has announced an updated examination, CCNA v2.0, that builds on the existing certification.

The exam code remains 200-301.

CCNA v2.0 Important Dates

Candidates can verify the transition through Cisco's official CCNA certification page.

CCNA v2.0 Exam Domains

Cisco's revised blueprint contains five major domains.

The first four domains account for 90% of the announced examination weighting.

This highlights the continued importance of network fundamentals, switching, routing, connectivity, and security.

Why Does the Update Matter?

The revised objectives frequently use practical action terms.

Examples include:

• Diagnose interface and cable faults.
• Troubleshoot IPv4 and IPv6 configurations.
• Configure 802.1Q trunks and EtherChannel.
• Troubleshoot static routing.
• Configure OSPFv2 and OSPFv3.
• Diagnose DNS problems.
• Configure supported Layer 2 security controls.
• Interpret operational logs and AI-generated recommendations.

These requirements involve more than recalling protocol definitions.

Cisco's official CCNA v2.0 Exam Topics provide the complete scope.

The important distinction is that CCNA v1.1 already required practical networking knowledge. CCNA v2.0 makes several configuration, diagnostic, and operational expectations more explicit.

1. Network Troubleshooting Requires Practical Diagnostic Skills

Troubleshooting is one of the most valuable networking skills because production environments rarely fail in exactly the same way.

Two users reporting identical symptoms may have different underlying problems.

For example, an employee who cannot access an application might have incorrect IP settings, an unavailable gateway, a DNS problem, or a network access restriction.

A Structured Troubleshooting Process

A useful troubleshooting workflow is:

           IDENTIFY THE SYMPTOM
                   |
                   v
           COLLECT INFORMATION
                   |
                   v
           CHECK BASIC CONNECTIVITY
                   |
                   v
           INVESTIGATE THE FAILURE
                   |
                   v
           FORM A HYPOTHESIS
                   |
                   v
           TEST ONE CHANGE
                   |
                   v
           VERIFY THE RESULT
                   |
                   v
           DOCUMENT THE CAUSE

Figure 1: A structured network troubleshooting process. Actual investigations may require repeating earlier steps as new evidence becomes available.

Essential Cisco IOS Commands

Availability and syntax can vary by device, operating system, and simulator.

Example: Diagnosing a Connectivity Failure

Suppose a computer can communicate with a local printer but cannot reach a server on another subnet.

The technician first checks the computer's IP address, subnet mask, and default gateway.

Next, they test the gateway and inspect router interfaces and routing information.

If the computer's gateway is incorrect, the technician can correct it and verify connectivity again.

Practical takeaway: The goal of troubleshooting is to identify the cause using evidence rather than repeatedly changing settings until a connection works.

2. IPv4, IPv6, and Subnetting Need Configuration Practice

IP addressing is one of the foundations of networking.

Every routed network depends on correctly configured addresses, prefixes, and gateway information.

Why Subnetting Matters

Subnetting divides an IP network into smaller networks.

For example, consider:

192.168.10.0/24

This IPv4 subnet uses a 24-bit network prefix.

In a conventional subnet, its usable host range is:

192.168.10.1 - 192.168.10.254

The address 192.168.10.255 is the subnet's broadcast address.

Practical Example: Two Departments

A computer configured as 192.168.10.10/24 belongs to the first network.

To reach the second network, it normally sends traffic to an appropriate gateway.

If that gateway is configured incorrectly, communication with remote networks may fail.

Why IPv6 Practice Is Important

CCNA v2.0 explicitly includes IPv6 address configuration, assignment, and prefix troubleshooting.

Candidates should understand:

• IPv6 unicast addressing.
• Prefix lengths.
• Link-local addresses.
• Basic IPv6 reachability.
• IPv6 routing.
• Common configuration mistakes.

For example, an incorrectly configured IPv6 prefix can cause a device to make incorrect assumptions about which destinations are on-link.

What Should You Practice?

Configure two subnets in a simulator and verify which destinations are local.

Then deliberately modify a subnet mask or default gateway.

Observe which communication paths continue to work and which fail.

Practical takeaway: Addressing becomes easier to understand when you see how incorrect prefixes and gateways affect actual network behavior.

3. Switching, VLANs, and Trunking Require Hands-On Configuration

Ethernet switching is essential for connecting devices inside local networks.

Switches learn MAC addresses and use forwarding information to move Ethernet frames between interfaces.

However, real network environments often contain multiple VLANs, trunks, and redundant connections.

What Is a VLAN?

A Virtual Local Area Network creates a logical Layer 2 broadcast domain.

For example, a business might organize devices into:

• VLAN 10: Employees
• VLAN 20: Finance
• VLAN 30: Guests

Devices can belong to different VLANs even when connected to the same physical switch.

What Is a Trunk Port?

A trunk interface carries traffic for multiple VLANs using supported tagging, commonly IEEE 802.1Q.

Trunks are frequently configured between switches or between switches and routing devices.

Why Is Configuration Knowledge Important?

Imagine a computer that should belong to VLAN 10.

Its switch port is accidentally assigned to VLAN 20.

The computer's IP configuration may remain unchanged, but it now connects to a different Layer 2 network.

As a result, it may no longer reach its intended default gateway.

A technician who understands VLAN behavior can use switching commands to identify the mismatch.

Other Important CCNA Switching Skills

The v2.0 blueprint includes practical work involving:

• Access-port configuration.
• 802.1Q trunk interfaces.
• Layer 2 and Layer 3 connectivity.
• LACP EtherChannel.
• Switch virtual interfaces.
• Rapid PVST+.
• CDP and LLDP.

Practical takeaway: Learn to configure switching features and verify their behavior through device output and actual traffic tests.

4. Routing Knowledge Must Go Beyond Command Memorization

Routing allows packets to move between different IP networks.

Routers examine destination addresses and use routing information to select forwarding paths.

Understanding the Routing Table

A routing table may contain:

• Directly connected routes.
• Static routes.
• Default routes.
• Dynamically learned routes.

Engineers need to understand the prefix, next hop, administrative distance, and metric associated with applicable routes.

Static Routing

Static routes are configured manually.

They can be useful in small networks and predictable routing environments.

OSPF Routing

Open Shortest Path First (OSPF) is a link-state routing protocol.

It allows routers to exchange routing information and calculate routes according to the protocol's rules.

The CCNA v2.0 objectives include single-area OSPFv2 for IPv4 and OSPFv3 for IPv6.

Practical Routing Example

Two routers connect separate office networks.

A computer in Office A cannot reach a server in Office B.

The technician examines the routing table and discovers that the router does not have the required destination route.

The next step is to investigate whether the missing route should be directly connected, statically configured, or learned through a routing protocol.

Practical takeaway: Understanding why a route exists—or does not exist—is more important than memorizing the command used to create it.

5. Network Security Requires Configuration and Verification

Security controls influence which network communication is permitted.

An incorrectly configured security rule can prevent legitimate traffic or leave sensitive resources unnecessarily accessible.

Important CCNA v2.0 Security Topics

Cisco's revised objectives include:

• IPv4 access control lists.
• Local user accounts.
• AAA clients using TACACS+ and RADIUS.
• DHCP snooping.
• Dynamic ARP Inspection.
• Port security.
• Storm control.
• IPv6 Router Advertisement Guard.

Some capabilities depend on the selected hardware, operating system, or simulator.

Practical Example: Employee and Guest Networks

A business has an employee network and a guest network.

Guests need internet access but should not access sensitive employee systems.

VLANs can separate the groups at Layer 2.

However, VLAN separation alone does not automatically enforce every required security restriction.

The organization must also configure appropriate routing and access policies.

Why Verification Matters

After applying an ACL, an engineer should confirm that authorized traffic continues working and restricted traffic is blocked.

A security configuration that looks correct but has not been tested may not provide the intended protection.

Practical takeaway: Network security depends on correctly implementing and verifying controls, not simply recognizing their names.

6. Wireless and Client Connectivity Need Diagnostic Skills

Wireless networking introduces additional variables that do not appear in every wired network.

Client connectivity problems may involve radio conditions, authentication, IP configuration, or upstream network services.

Common Wireless Problems

Examples include:

• Weak signal coverage.
• Channel interference.
• Incorrect wireless security settings.
• Authentication failures.
• Incorrect DHCP configuration.
• DNS problems.
• Gateway or routing failures.

Practical Example

A laptop successfully connects to the office Wi-Fi network but cannot open an internal application.

The wireless connection may be working correctly.

The technician should also examine IP addressing, DNS resolution, gateway reachability, and the application's availability.

What Does CCNA v2.0 Cover?

The revised exam includes wired and wireless client connectivity troubleshooting on Windows, macOS, and Linux.

It also includes wireless principles such as RF characteristics, channels, interference, and security protocols.

Practical takeaway: Wireless connectivity troubleshooting requires understanding the complete communication path, not just signal strength.

7. AI-Assisted Network Operations Still Require Human Judgment

AI-assisted network operations are becoming more relevant as network management tools gain automated analysis and recommendation capabilities.

Cisco's CCNA v2.0 blueprint includes agentic AI, generative AI prompting, network management approaches, and the interpretation of operational information.

How Can AI Help Network Engineers?

An AI assistant may help:

• Summarize network logs.
• Identify possible causes of connectivity problems.
• Explain command output.
• Compare configuration information.
• Suggest troubleshooting steps.
• Organize network documentation.

These capabilities can support investigations, but they do not eliminate the need for technical knowledge.

Practical Example: An Incorrect Recommendation

Suppose an AI assistant analyzes network information and suggests that a missing static route is causing a connectivity problem.

The engineer checks the routing table and discovers that both required networks are already directly connected.

The actual problem is a VLAN assignment mismatch.

Following the AI's recommendation without verification could introduce an unnecessary route and leave the original problem unresolved.

How Should You Evaluate AI Recommendations?

Begin by comparing the recommendation with actual device output.

Ask whether the explanation matches the topology, interface status, addresses, and routing information.

Use appropriate tests before making changes, and avoid sharing sensitive configurations or credentials with unapproved AI tools.

Practical takeaway: AI can help network engineers investigate problems, but practical networking skills remain necessary to validate its conclusions.

CCNA v1.1 vs. CCNA v2.0: What's Different?

The refreshed blueprint builds on the networking fundamentals already included in CCNA v1.1.

The changes should not be interpreted as a complete replacement of previous networking knowledge.

The strongest preparation strategy is to understand the underlying networking principles and practice applying them in different configurations and failure scenarios.

Hands-On CCNA 2027 Lab: Configure VLANs and Inter-VLAN Routing

Let's build a small network that connects two departments through a switch and router.

We'll use Cisco Packet Tracer.

The objective is to configure two VLANs, create an 802.1Q trunk, enable inter-VLAN routing, and verify that devices can communicate.

Afterward, we'll deliberately introduce two configuration problems and troubleshoot them.

Lab Requirements

Use the following devices in Packet Tracer:

• One Cisco router supporting 802.1Q subinterfaces.
• One Cisco Layer 2 switch.
• Two PCs.
• Three appropriate Ethernet cables.

A commonly used Packet Tracer combination is a Cisco 1941 router and a Cisco 2960 switch.

Commands and interface names may differ on other models.

Figure 3: Router-on-a-stick topology using two VLANs and a single physical router-to-switch link.

IP Addressing Plan

Assume the router's GigabitEthernet0/0 interface connects to the switch's FastEthernet0/24 interface.

Step 1: Create the VLANs

Open the switch CLI.

Enter privileged EXEC mode and global configuration mode:

enable
configure terminal

Create VLAN 10:

vlan 10
 name EMPLOYEES
exit

Create VLAN 20:

vlan 20
 name FINANCE
exit

The switch now has two configured VLANs.

Step 2: Configure Switch Access Ports

Assign the first PC to VLAN 10.

interface fastethernet0/1
 switchport mode access
 switchport access vlan 10
exit

Assign the second PC to VLAN 20.

interface fastethernet0/2
 switchport mode access
 switchport access vlan 20
exit

These ports operate as access ports and carry the traffic associated with their configured VLANs.

Verify the VLAN Assignments

Run:

end
show vlan brief

The output should indicate that FastEthernet0/1 belongs to VLAN 10 and FastEthernet0/2 belongs to VLAN 20.

Step 3: Configure the 802.1Q Trunk

The router needs to receive traffic from both VLANs through one physical interface.

Configure the switch port connected to the router:

configure terminal

interface fastethernet0/24
 switchport mode trunk
 switchport trunk allowed vlan 10,20
exit

end

This configures the interface to carry VLAN 10 and VLAN 20 traffic.

Depending on the switch model, additional trunk encapsulation settings may be required.

The common Packet Tracer 2960 switch uses 802.1Q trunking.

Verify the Trunk

Run:

show interfaces trunk

Check that FastEthernet0/24 is operating as a trunk and that VLANs 10 and 20 are permitted.

Step 4: Configure Router Subinterfaces

Open the router CLI.

Enter global configuration mode:

enable
configure terminal

Enable the physical interface:

interface gigabitethernet0/0
 no shutdown
exit

Configure the VLAN 10 subinterface:

interface gigabitethernet0/0.10
 encapsulation dot1Q 10
 ip address 192.168.10.1 255.255.255.0
exit

Configure the VLAN 20 subinterface:

interface gigabitethernet0/0.20
 encapsulation dot1Q 20
 ip address 192.168.20.1 255.255.255.0
exit

end

The router now has two logical subinterfaces.

Each subinterface uses a VLAN tag and provides a gateway address for its respective network.

This approach is commonly called router-on-a-stick.

Why Does This Work?

A PC in VLAN 10 sends traffic destined for a different subnet to its default gateway.

The switch forwards the appropriate tagged traffic through the trunk.

The router receives the packet on the relevant subinterface, determines the destination route, and forwards it toward the second VLAN.

Step 5: Configure PC IP Addresses

In Packet Tracer, open each PC and navigate to its IP configuration settings.

PC-A

IP address:       192.168.10.10
Subnet mask:      255.255.255.0
Default gateway:  192.168.10.1

PC-B

IP address:       192.168.20.10
Subnet mask:      255.255.255.0
Default gateway:  192.168.20.1

These values must match the VLAN and router configuration.

Step 6: Verify Router Interfaces and Routes

On the router, run:

show ip interface brief

The two subinterfaces should have their configured IP addresses and operational status.

Next, inspect the routing table:

show ip route

The expected routing information should include directly connected networks equivalent to:

C 192.168.10.0/24 is directly connected,
  GigabitEthernet0/0.10

C 192.168.20.0/24 is directly connected,
  GigabitEthernet0/0.20

The exact output formatting depends on the device.

The C route code indicates a directly connected network.

Because both networks are directly connected to router subinterfaces, no additional static route is needed for this topology.

Step 7: Test Inter-VLAN Communication

Open PC-A's command prompt.

Run:

ping 192.168.20.10

If the configuration and connectivity are correct, the ping should succeed.

You can also test each PC's default gateway.

From PC-A:

ping 192.168.10.1

From PC-B:

ping 192.168.20.1

What Does a Successful Ping Prove?

A successful ping confirms that ICMP echo requests and replies can traverse the tested path.

It does not automatically prove that every application protocol will work.

For this lab, however, it provides a useful basic connectivity test.

The first attempt may time out while address resolution and switching information are learned.

Step 8: Troubleshooting Lab — Wrong VLAN Assignment

Now we'll intentionally create a problem.

Only perform this exercise in your own Packet Tracer lab.

Introduce the Fault

On the switch, move PC-A's access port from VLAN 10 to VLAN 20.

configure terminal

interface fastethernet0/1
 switchport access vlan 20
exit

end

PC-A still has the IPv4 address 192.168.10.10/24.

However, its switch port now belongs to VLAN 20.

Test Connectivity Again

From PC-A, run:

ping 192.168.10.1

The ping should fail under the intended lab configuration because PC-A is no longer connected to the Layer 2 VLAN where its configured gateway resides.

Diagnose the Problem

On the switch, run:

show vlan brief

Inspect the VLAN assignment for FastEthernet0/1.

You should observe that the port belongs to VLAN 20 rather than VLAN 10.

Correct the Configuration

Restore the intended VLAN:

configure terminal

interface fastethernet0/1
 switchport access vlan 10
exit

end

Repeat the connectivity tests.

What Did You Learn?

The fault was not caused by a missing route.

It was caused by a mismatch between the host's IP network and its switch-port VLAN.

This demonstrates why checking Layer 2 connectivity is important before changing routing configurations.

Step 9: Troubleshooting Lab — Incorrect Default Gateway

Restore the original working topology before starting this exercise.

Next, open PC-B's IP configuration.

Change its default gateway from:

192.168.20.1

to:

192.168.20.254

Leave the IP address and subnet mask unchanged.

Test Connectivity

From PC-B, test the router's actual VLAN 20 address:

ping 192.168.20.1

This ping may still succeed because both addresses are on the same local subnet.

Now test PC-A:

ping 192.168.10.10

The inter-VLAN test should fail under the intended configuration.

Why Does the Failure Occur?

PC-B knows that 192.168.10.10 is on a different subnet.

It therefore attempts to forward the packet through its configured default gateway.

However, 192.168.20.254 is not the active router gateway in this lab.

The packet cannot follow the intended routed path.

Correct the Gateway

Restore:

192.168.20.1

Then repeat the ping to PC-A.

Important Troubleshooting Lesson

A computer can have an active network connection and successfully communicate with local devices while still having an incorrect default gateway.

This is why local connectivity and remote-subnet connectivity should be tested separately.

Step 10: Document and Verify the Final Network

After restoring the correct configuration, perform the following checks.

Save the working configuration in your simulator and document the faults you introduced.

For each fault, record the original configuration, symptoms, diagnostic commands, root cause, correction, and final test result.

What This Lab Teaches

The complete exercise combines:

• VLAN configuration.
• Access-port assignments.
• 802.1Q trunking.
• Router subinterfaces.
• IPv4 addressing.
• Default gateways.
• Routing table interpretation.
• Cisco IOS verification commands.
• Connectivity troubleshooting.
• Root-cause documentation.

The most valuable result is not simply making the network work. It is understanding why it works, why a particular fault breaks it, and how to restore communication using evidence.

Five Additional Hands-On CCNA 2027 Labs

After completing the VLAN lab, expand your practice with these exercises.

How to Practice Effectively

Begin each exercise with a known working configuration.

Test it and record the expected output.

Then introduce one controlled configuration error.

Investigate the resulting symptoms using the appropriate verification commands.

Finally, correct the problem and confirm that the original tests succeed.

Changing one variable at a time helps make the cause-and-effect relationship easier to understand.

Practical Exercise: Evaluate an AI Network Troubleshooting Recommendation

The CCNA v2.0 blueprint includes evaluating AI-generated recommendations as part of network operations.

Let's practice the reasoning involved.

Scenario

You have completed the VLAN lab.

PC-A cannot reach its default gateway.

An AI assistant suggests:

Add a static route to the 192.168.10.0/24 network on the router.

Step 1: Review the Evidence

The router already has a directly connected route for 192.168.10.0/24.

Its VLAN 10 subinterface is configured.

Step 2: Evaluate the Recommendation

The recommendation does not address the most likely cause.

The network is already directly connected.

Adding another route is unnecessary for the intended topology.

Step 3: Investigate Layer 2

Check:

show vlan brief

Then:

show interfaces trunk

You discover that PC-A's access port is assigned to the wrong VLAN.

Step 4: Correct and Verify

Restore the correct VLAN assignment and repeat the ping tests.

What Does This Demonstrate?

AI-generated advice can appear plausible while being technically inappropriate.

The engineer needs to compare recommendations with actual device information.

The correct workflow is to use AI as an investigation aid, not as a substitute for understanding networking behavior.

Best Tools for Hands-On CCNA Preparation

Which Tool Should Beginners Use?

Packet Tracer is a practical starting point because it supports many foundational addressing, switching, routing, and troubleshooting scenarios.

More advanced tools can be introduced when a particular learning requirement exceeds the simulator's capabilities.

An Eight-Week CCNA 2027 Hands-On Learning Roadmap

A structured plan helps learners progress from individual concepts to more complex troubleshooting scenarios.

This roadmap focuses on practical development.

The time required for full CCNA preparation depends on the learner's existing knowledge and the complete exam objectives.

How Should You Structure Each Study Session?

Use a repeatable learning process.

First, understand the purpose of the technology.

Second, configure a working example.

Third, verify its behavior.

Fourth, introduce a controlled fault.

Fifth, troubleshoot and correct the issue.

Finally, document what you learned.

This makes practical exercises more meaningful than repeatedly copying configuration commands.

Common Mistakes CCNA 2027 Candidates Should Avoid

Memorizing Commands Without Understanding Their Output

A command can execute successfully while the network still behaves incorrectly.

Learn what each command does and which conditions its output confirms.

Studying Only Theory Questions

Conceptual study is important, but it cannot fully replace configuration and troubleshooting experience.

Combine theoretical study with practical lab exercises.

Ignoring IPv6

IPv6 is explicitly included in the CCNA v2.0 objectives.

Practice IPv6 addressing, prefix interpretation, and connectivity diagnosis alongside IPv4.

Avoiding Troubleshooting Until the End

Troubleshooting becomes easier when practiced throughout the learning process.

Introduce small configuration errors after each successful lab.

Trusting AI Recommendations Without Verification

AI can generate technically incorrect or incomplete suggestions.

Always compare recommendations with the actual configuration, topology, and observed behavior.

Using Outdated Exam Objectives

CCNA v1.1 and v2.0 have different exam blueprints.

Use the objectives corresponding to your intended testing date.

Changing Several Settings at Once

Making many changes simultaneously can hide the actual cause of a problem.

Investigate systematically and verify each correction.

Do Hands-On CCNA Skills Help With Networking Careers?

Practical networking experience is relevant to roles involving infrastructure support, connectivity troubleshooting, network administration, and network operations.

For example, a junior network engineer may need to investigate why one department cannot reach a business application.

The engineer must understand interfaces, VLANs, IP addressing, routing, and security restrictions to narrow down the cause.

The ability to interpret command output and document the solution is often more directly applicable to this responsibility than memorizing isolated definitions.

However, certification and lab experience do not guarantee employment.

Communication, teamwork, documentation, and broader technical knowledge also matter.

Hands-on labs provide an opportunity to build these capabilities in a structured environment.

What Is the Best Way to Practice Troubleshooting?

Build a working network, record expected results, introduce a controlled fault, inspect the symptoms, identify the cause, and verify the correction.

Should I Stop Studying CCNA v1.1 and Wait for v2.0?

Not necessarily.

Cisco has advised candidates already preparing for v1.1 to continue studying if their exam schedule permits.

The underlying networking fundamentals remain valuable across both versions.

Conclusion: Why Practical Networking Knowledge Matters in CCNA 2027

CCNA v2.0 reflects the importance of being able to configure, troubleshoot, and operate networks rather than relying only on theoretical knowledge.

The updated objectives cover diagnosing physical connectivity problems, troubleshooting IPv4 and IPv6, configuring switching technologies, interpreting routes, applying security controls, and working with network operations information.

The introduction of additional AI-related objectives also reinforces the need for technical judgment.

An engineer must understand the network well enough to determine whether an automated recommendation is appropriate.

The Packet Tracer lab in this guide demonstrates how several foundational networking concepts work together.

VLANs organize Layer 2 communication, trunk links carry multiple VLANs, router subinterfaces support inter-VLAN routing, and default gateways help hosts reach remote networks.

The troubleshooting exercises reveal why a working configuration can fail after a small change.

For beginners, the most effective approach is to study a concept, configure it, verify its behavior, intentionally introduce a fault, and identify the root cause.

The most valuable networking skill for CCNA 2027 is not memorizing configuration commands. It is understanding how a network should behave, recognizing when it behaves differently, and using evidence to restore the intended operation.

Your next step is to recreate the VLAN lab in Cisco Packet Tracer, verify successful communication, and complete both troubleshooting scenarios.

Afterward, extend the topology with another switch, an additional router, or a controlled access policy.

That experience will strengthen the foundation needed for CCNA preparation and future networking responsibilities.
