Zorluk: OrtaCompTIA Troubleshooting Methodology

A network administrator is investigating an issue where database servers in a secondary rack lose connectivity to primary application servers during nightly backup windows. The administrator gathered user reports, confirmed the link failures, established a theory that an automated backup job was saturating the inter-switch trunk, and performed packet captures during a test run to confirm this theory as the verified root cause. According to the CompTIA troubleshooting methodology, which of the following should the network administrator do NEXT?

  1. Establish a plan of action to rate-limit backup traffic and identify potential side effects.Cevap
  2. B
    Apply a Quality of Service (QoS) policy on the trunk switchports to prioritize application traffic.
  3. C
    Execute end-to-end ping and database query benchmarks to confirm uninterrupted connectivity.
  4. D
    Update the infrastructure ticketing system with the packet capture findings and resolution history.

Cevap

Establish a plan of action to rate-limit backup traffic and identify potential side effects.
The scenario describes a technician who has successfully tested their theory and verified the root cause using packet captures (Step 3). According to the CompTIA troubleshooting methodology, the direct next phase is Step 4: Establish a plan of action to resolve the problem and identify potential side effects.

Adım Adım Çözüm

1
Identify current position in CompTIA 7-step troubleshooting methodology.
The technician completed Step 1 (Identify problem), Step 2 (Establish theory of probable cause), and Step 3 (Test theory to determine cause by analyzing packet captures).
Determining the completed step dictates the required next action in the rigid methodology sequence.
2
Determine the sequential next step following Step 3.
Step 4 is 'Establish a plan of action to resolve the problem and identify potential side effects'.
Before making changes in a production network, a technician must design the remediation steps and evaluate potential operational risks or unwanted impacts.
3
Match the correct step to the corresponding option.
Developing a plan to rate-limit backup traffic while considering potential side effects directly aligns with Step 4.
This maintains administrative safety and adherence to proper change management controls before implementation.
