Question 480
A tester is asked to assess 802.11 channel utilization and coverage without disruption. Which authorized assessment decision best addresses this particular situation?
Explanation
Correct Answer
Perform a nontransmitting wireless site survey and record signal strength. This answer directly addresses the described constraint. Radio surveys can evaluate exposure without performing active interference. Successful validation requires: The output maps approved radios to their channels and signal levels.
Incorrect Answers
That approach concerns a different situation: a perimeter scanner reports only accessible services despite many privately hosted backend applications. An external scan cannot claim coverage of unreachable systems. The required result is that the output maps approved radios to their channels and signal levels. The appropriate action is: Perform a nontransmitting wireless site survey and record signal strength.
That relates to a different issue: A production application uses a library with an outdated version, but the build is opaque. A reliable component inventory is needed before asserting specific package risk. That is not a direct remedy for the requested outcome: The output maps approved radios to their channels and signal levels. The appropriate action is: Perform a nontransmitting wireless site survey and record signal strength.
It would address a vulnerability analyst needs to assess a publicly reachable web server's unsafe headers and default files. The relevant reason in that case is: Web configuration assessment targets service weaknesses distinct from full code review. Here the required success condition is the output maps approved radios to their channels and signal levels. The appropriate action is: Perform a nontransmitting wireless site survey and record signal strength.
