Domain 1: Troubleshooting Methodology and Frameworks
1. A help desk technician receives a call from a frustrated user who reports, "The
internet is completely down, and I can't do my job. I've been trying to fix it for an
hour, and nothing works." According to the CompTIA troubleshooting
methodology, what should the technician do FIRST?
• A) Immediately escalate the ticket to the network engineering team since
the user has already attempted self-resolution.
• B) Ask the user to reboot their computer and router to eliminate any
transient issues.
• C) Gather information by asking open-ended questions to understand the
exact symptoms and scope of the problem.
• D) Remotely ping the user's default gateway to verify Layer 3 connectivity.
Correct DETAILED ANSWER: C) Gather information by asking open-ended
questions to understand the exact symptoms and scope of the problem.
,Explanation:
• Why C is correct: The CompTIA troubleshooting model begins with a
critical first step: "Identify the Problem." This involves gathering
information from the user through effective questioning, establishing a
baseline of what has changed, and clarifying symptoms. The user's
statement is emotionally charged and vague ("completely down" could
mean one specific website, all websites, or no network at all). Asking open-
ended questions such as "What exactly happens when you try to access the
internet?" or "Is this affecting just you or your coworkers as well?" prevents
jumping to conclusions and potential misdiagnosis. Skipping this step risks
applying incorrect solutions, wasting time, and frustrating the user further.
• Incorrect options summarized:
o A: Escalation is premature without first identifying the problem and
attempting resolution within the scope of the help desk. The
technician has not yet determined the root cause or even verified
the symptoms.
o B: Although rebooting is a common step, it is not the first action.
Without understanding the problem, rebooting could destroy
temporary evidence (such as error messages) and frustrates the user
who may have already tried this.
o D: Pinging the gateway is a testing step that
comes after establishing a theory of probable cause. Action should
not be taken before information gathering.
2. A technician has gathered information, identified symptoms, and established a
theory of probable cause: a misconfigured DNS server address on a single
workstation. They modify the DNS setting from the incorrect address 8.8.8.7 to the
, correct corporate DNS server 10.10.10.5. After making the change, the user can
now access internal resources by hostname. What is the technician's NEXT step
according to the formal troubleshooting model?
• A) Document the findings, actions, and resolution in the ticket.
• B) Implement preventive measures by locking down the network settings
via Group Policy.
• C) Verify full system functionality by testing access to other critical
resources and ensuring no other issues were caused.
• D) Escalate the ticket to the networking team to investigate why the
incorrect DNS address was assigned.
Correct DETAILED ANSWER: C) Verify full system functionality by testing access to
other critical resources and ensuring no other issues were caused.
Explanation:
• Why C is correct: After implementing a solution, the next step in the
CompTIA model is to "Verify Full System Functionality and, if applicable,
implement preventive measures." Verification is crucial. The technician
must confirm that the fix not only resolved the immediate reported
symptom but also did not introduce any new issues. They should test other
applications, mapped drives, and internal/external website access to ensure
full operability. This step confirms the solution's completeness before the
ticket is closed.
• Incorrect options summarized:
o A: Documentation is the final step, occurring only after the solution
is verified and the user confirms the issue is resolved.
o B: Implementing preventive measures is part of the same step as
verification but comes after verifying that the immediate fix is
working correctly. The primary next action is verification.
