Zorluk: OrtaCompTIA Troubleshooting Methodology

A network administrator is investigating an issue where corporate users cannot authenticate to the 802.1X wireless network following a server maintenance window. The administrator suspects that an expired RADIUS server SSL certificate is preventing successful EAP-TLS handshakes. To test this theory, the administrator installs a valid test certificate on a staging RADIUS server and successfully authenticates a test client. According to the CompTIA troubleshooting methodology, what is the immediate NEXT step the administrator should perform?

  1. Establish a plan of action to deploy the renewed certificate in production and implement the solution.Cevap
  2. B
    Document the root cause, test results, and certificate installation steps in the change management tracking system.
  3. C
    Verify full system functionality across affected wireless access points and configure certificate expiration monitoring alerts.
  4. D
    Gather network logs from affected access points and interview users to determine if other wireless SSIDs are impacted.

Cevap

Establish a plan of action to deploy the renewed certificate in production and implement the solution.
The technician has completed Step 3 of the CompTIA troubleshooting methodology by testing and confirming the theory on a staging environment. The immediate next phase (Step 4) requires establishing a plan of action to resolve the issue in the live environment and implementing that solution.

Adım Adım Çözüm

1
Identify current phase in CompTIA troubleshooting methodology
The technician suspected an expired RADIUS certificate (Establish a theory - Step 2) and tested it on a staging server successfully (Test the theory - Step 3).
Confirming that authentications succeed with a valid test certificate validates the root cause theory.
2
Determine the next sequential phase
Following Step 3 (Test the theory to determine cause), the official CompTIA methodology mandates Step 4: Establish a plan of action to resolve the problem and implement the solution.
A formal rollout plan must be created and executed (including change approval if required) before verifying full system functionality.
