The answer is AES, as it is the gold standard for WPA2 and WPA3 encryption. AES, or Advanced Encryption Standard, is the most secure encryption method available because WPA2 mandates AES-CCMP and WPA3 uses AES-GCMP, both built on the AES block cipher to provide strong data confidentiality and integrity, unlike the older and weaker TKIP which is deprecated. On the CompTIA Network+ N10-009 exam, this question tests your understanding of wireless security standards and the evolution from TKIP to AES; a common trap is confusing TKIP as acceptable for modern networks when it is only a backward-compatibility fallback. Remember the memory tip: “AES is the best, TKIP is a relic—always pick AES for secure WPA2/3.”
N10-009 Network Implementation Practice Question
This N10-009 practice question tests your understanding of network implementation. 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 company is deploying a new wireless network for employee devices and wants to use the most secure encryption method currently available for WPA2/3. Which encryption standard should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AES
AES (Advanced Encryption Standard) is the most secure encryption method available for WPA2 and WPA3. WPA2 mandates AES-CCMP, and WPA3 uses AES-GCMP, both of which are based on the AES block cipher, providing strong confidentiality and integrity. This makes AES the correct choice for the highest security in modern Wi-Fi deployments.
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.
✗
WEP
Why it's wrong here
WEP is an outdated and insecure encryption protocol easily cracked with modern tools.
✗
TKIP
Why it's wrong here
TKIP was designed as a temporary fix for WEP but is no longer considered secure and is deprecated in Wi-Fi standards.
✓
AES
Why this is correct
AES is a strong symmetric encryption algorithm used in WPA2 and WPA3 to provide robust wireless security.

✗
DES
Why it's wrong here
DES is a legacy encryption algorithm not used in wireless networks; it has been replaced by AES.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that TKIP is acceptable for WPA2 security, but the trap is that WPA2 mandates AES-CCMP for certification, and TKIP is only a backward-compatible option that should never be used in a secure deployment.
Detailed technical explanation
How to think about this question
AES operates as a symmetric block cipher with 128-bit blocks and key sizes of 128, 192, or 256 bits. In WPA2, AES is used in Counter Mode with CBC-MAC (CCMP) to provide both encryption and integrity, while WPA3 uses AES in Galois/Counter Mode (GCMP) for authenticated encryption. A subtle real-world behavior is that some older enterprise access points may still support TKIP as a fallback, but enabling it disables the full security benefits of AES and can degrade performance due to per-packet key mixing overhead.

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 N10-009 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.
