- A
Change the encryption from AES to TKIP.
Why wrong: TKIP is weaker and also vulnerable to KRACK; this would not improve security.
- B
Enable WPA2-Enterprise with 802.1X.
Why wrong: WPA2-Enterprise still uses the same four-way handshake and is vulnerable to KRACK attacks; it does not address the vulnerability.
- C
Upgrade to WPA3-Personal.
WPA3 uses SAE, which is resistant to KRACK attacks because it uses a different handshake process that prevents key reinstallation.
- D
Implement MAC address filtering.
Why wrong: MAC filtering is an access control measure, not an encryption protocol; it does not protect against KRACK attacks.

220-1202 Wireless Security Protocols Practice Question
This 220-1202 practice question tests your understanding of wireless security protocols. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 security policy mandates that all wireless traffic must be encrypted using a protocol that is resistant to KRACK attacks. The current network uses WPA2-PSK with AES. Which of the following upgrades should be implemented to meet this requirement?
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
✓
Upgrade to WPA3-Personal.
WPA3-Personal replaces the Pre-Shared Key (PSK) handshake with Simultaneous Authentication of Equals (SAE), which is resistant to offline dictionary attacks and the KRACK vulnerability that exploits the 4-way handshake in WPA2. Since the policy requires encryption resistant to KRACK attacks, upgrading to WPA3-Personal directly addresses this requirement.
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.
- ✗
Change the encryption from AES to TKIP.
Why it's wrong here
TKIP is weaker and also vulnerable to KRACK; this would not improve security.
- ✗
Enable WPA2-Enterprise with 802.1X.
Why it's wrong here
WPA2-Enterprise still uses the same four-way handshake and is vulnerable to KRACK attacks; it does not address the vulnerability.
- ✓
Upgrade to WPA3-Personal.
Why this is correct
WPA3 uses SAE, which is resistant to KRACK attacks because it uses a different handshake process that prevents key reinstallation.

- ✗
Implement MAC address filtering.
Why it's wrong here
MAC filtering is an access control measure, not an encryption protocol; it does not protect against KRACK attacks.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that changing authentication methods (e.g., from PSK to 802.1X) fixes protocol-level vulnerabilities like KRACK, when in fact the underlying handshake protocol (WPA2) remains the same and still vulnerable.
Detailed technical explanation
How to think about this question
KRACK (Key Reinstallation Attack) exploits a vulnerability in the 4-way handshake of WPA2 by forcing nonce reuse, allowing an attacker to decrypt traffic without knowing the Pre-Shared Key. WPA3-Personal uses SAE (Simultaneous Authentication of Equals), based on the Dragonfly handshake, which provides forward secrecy and is immune to the 4-way handshake replay and nonce reuse issues that enable KRACK. In a real-world scenario, even with WPA2-Enterprise, an attacker positioned between the client and AP can still perform a KRACK attack by manipulating handshake messages.
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.
