Q: 12
You were previously onsite at XYZ’s facility to conduct a pre-deployment RF site survey. The WLAN
has been deployed according to your recommendations and you are onsite again to perform a post-
deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that
must be performed?

C , because you have to actually place a VoWiFi call to confirm the real user experience and QoS after deployment. Just checking for interference (A) or channel use (D) isn’t enough for proper validation. Anyone see it differently?
C , seen similar in official practice, always says to run a real VoWiFi call during validation.
Maybe A. Had something like this in a mock and spectrum analysis was highlighted as key for post-deployment, especially to catch last-minute interference issues. Not 100% sure though, could see C making sense too.
Not A, it's got to be C. Actually placing a VoWiFi call is essential for true validation after deployment-A is just a classic distraction for folks thinking about general RF issues instead of user QoS. Seen this in CWNA practice too.
A, This option makes sense since interference sources directly impact VoWiFi quality, pretty sure that's a must-find during validation. I know C is popular but A feels like the trap here, correct me if I'm off.
Its C, you have to actually test with a VoWiFi call to validate quality for end users. Option A trips people up but that's more about troubleshooting, not standard validation.
C or D? I remember a similar scenario from labs and we always checked neighboring AP channel usage. Could be wrong but D feels like a must-have step.
C tbh. The post-deployment for VoWiFi isn't just about spotting interference (that's where A tries to trick people), but about real-world validation like making a call. Pretty sure that's the only way to fully check QoS. Anyone disagree?
C or A. I see why spectrum analysis (A) looks solid, since interference can ruin VoWiFi, but I usually think testing with an actual phone call (C) might get missed as a must-do step. Anyone else tripped up by this trap between C and A on practice exams?
Be respectful. No spam.
