- A
WPA2-PSK with TKIP.
Why wrong: TKIP is deprecated and insecure; it is not the strongest available.
- B
WPA2-PSK with AES.
Why wrong: AES is strong, but WPA3-SAE is stronger and more modern.
- C
WPA3-SAE.
WPA3-SAE is the current strongest standard, offering improved security over WPA2.
- D
A mixed mode of WPA2 and WPA3.
Why wrong: Mixed mode may allow devices to connect using the less secure WPA2, violating the policy.

220-1202 Wireless Security Protocols Practice Question
This 220-1202 practice question tests your understanding of wireless security protocols. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 company's IT policy requires that all wireless traffic be encrypted using the strongest available protocol. A technician is configuring a new access point that supports WPA3-SAE, WPA2-PSK with AES, and WPA2-PSK with TKIP. Which configuration meets the policy?
Answer choices
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
✓
WPA3-SAE.
WPA3-SAE (Simultaneous Authentication of Equals) is the strongest available wireless encryption protocol among the options, as it replaces the pre-shared key (PSK) model with a more secure handshake that provides forward secrecy and is resistant to offline dictionary attacks. The IT policy requires the strongest available protocol, and WPA3-SAE is superior to both WPA2-PSK variants, making option C the correct choice.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
WPA2-PSK with TKIP.
Why it's wrong here
TKIP is deprecated and insecure; it is not the strongest available.
- ✗
WPA2-PSK with AES.
Why it's wrong here
AES is strong, but WPA3-SAE is stronger and more modern.
- ✓
WPA3-SAE.
- ✗
A mixed mode of WPA2 and WPA3.
Why it's wrong here
Mixed mode may allow devices to connect using the less secure WPA2, violating the policy.
Common exam traps
Common exam trap: answer the scenario, not the keyword
A common misconception is that WPA2-PSK with AES is the strongest option because it uses the AES cipher, but the trap here is that the security of the authentication handshake (SAE vs. PSK) is more critical than the encryption cipher, and WPA3-SAE provides a fundamentally stronger authentication mechanism.
Detailed technical explanation
How to think about this question
WPA3-SAE implements the Dragonfly handshake (based on RFC 7664), which uses a password-authenticated key exchange (PAKE) to establish a shared secret without transmitting the password over the air, providing forward secrecy even if the password is later compromised. In contrast, WPA2-PSK relies on a four-way handshake that transmits a nonce and MIC derived from the PSK, which can be captured and cracked offline using tools like aircrack-ng. A real-world scenario where this matters is in high-security environments like corporate offices or government facilities, where an attacker with captured WPA2 handshakes can brute-force weak passwords, whereas WPA3-SAE prevents this even with weak passwords.
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 practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
