- A
Rogue access point performing a deauthentication attack
Rogue APs send deauth frames to disconnect clients.
- B
Channel interference
Why wrong: Interference affects signal quality, not deauth frames.

Power save mode
Why wrong: Power save mode is a client power management feature.
- D
DHCP server exhaustion
Why wrong: DHCP exhaustion would affect IP availability, not deauth.
- E
Weak encryption
Why wrong: Encryption does not cause deauth frames.

This SSCP practice question tests your understanding of sscp exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator notices that wireless users are experiencing intermittent connectivity. The controller shows excessive deauthentication frames. What is the most likely cause?

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Deauthentication frames are unauthenticated management frames in 802.11, meaning any device can spoof them using tools like aireplay-ng. The attack works by sending a deauth frame with the spoofed MAC address of the access point to the client, forcing disassociation. This is a common vector for WPA/WPA2 handshake capture and is not mitigated by encryption alone; 802.11w (Management Frame Protection) was introduced to address this vulnerability.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
