SSCP Practice Question: A network administrator notices that wireless…
A network administrator notices that wireless users are experiencing intermittent connectivity. The controller shows excessive deauthentication frames. What is the most likely cause?
⚠ Common exam trap
ISC2 often tests the distinction between deauthentication attacks and other wireless issues like channel interference or DHCP exhaustion, trapping candidates who confuse symptoms of a DoS attack with normal network problems.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Rogue access point performing a deauthentication attack
Excessive deauthentication frames are a hallmark of a deauthentication attack, where a rogue access point sends forged 802.11 management frames to disconnect clients. This causes intermittent connectivity as clients repeatedly lose association and attempt to reconnect. The controller logs these frames as a clear indicator of an active attack.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Rogue access point performing a deauthentication attack
Why this is correct
Rogue APs send deauth frames to disconnect clients.
- ✗
Channel interference
Why it's wrong here
Interference affects signal quality, not deauth frames.
- ✗
Power save mode
Why it's wrong here
Power save mode is a client power management feature.
- ✗
DHCP server exhaustion
Why it's wrong here
DHCP exhaustion would affect IP availability, not deauth.
- ✗
Weak encryption
Why it's wrong here
Encryption does not cause deauth frames.
