Due to concerns around single points of failure, a company decided to add an additional WAN to the network. The company added a second MPLS vendor to the current MPLS WAN and deployed an additional WAN router at each site. Both MPLS providers use OSPF on the WAN network, and EIGRP is run internally. The first site to go live with the new WAN is successful, but when the second site is activated, significant network issues occur. Which of the following is the most likely cause for the WAN instability?

Question 21 - N10-009 discussion

Which of the following steps of the troubleshooting methodology would most likely include checking through each level of the OSI model after the problem has been identified?

Establish a theory.

Implement the solution.

Create a plan of action.

Verify functionality.

Suggested answer: D

Explanation:

Introduction to Troubleshooting Methodology:

Network troubleshooting involves a systematic approach to identifying and resolving network issues. The CompTIA Network+ certification emphasizes a structured troubleshooting methodology.

Troubleshooting Steps:

Identify the problem: Gather information, identify symptoms, and question users.

Establish a theory of probable cause: Consider possible reasons for the issue.

Test the theory to determine cause: Validate the theory with tests.

Establish a plan of action to resolve the problem and implement the solution: Create and execute a resolution plan.

Verify functionality and implement preventive measures: Ensure the solution works and prevent recurrence.

Verifying Functionality:

After implementing a solution, verifying functionality ensures that the problem is fully resolved. This involves testing the network to confirm that it operates correctly.

Checking through each level of the OSI model helps to ensure that all potential issues at different layers (physical, data link, network, transport, session, presentation, and application) are addressed.

Explanation of the Options:

A . Establish a theory: This step involves hypothesizing possible causes, not verifying functionality.

B . Implement the solution: This step involves executing the resolution plan.

C . Create a plan of action: This step involves planning the resolution, not verification.

D . Verify functionality: This step involves comprehensive checks, including OSI model layers, to ensure the issue is fully resolved.

Conclusion:

Verifying functionality is a critical step in the troubleshooting process, ensuring that the network operates correctly after a solution is implemented. It involves thorough testing across all OSI model layers.
