Wireless Encryption: AES Requirement for Home Networks
Short answer
C WPA2 is the wireless encryption technology that mandates the use of AES to secure home wireless networks.
Question
Key Takeaways
The exam tests knowledge of Wi-Fi security evolution, specifically the trap of confusing WPA's temporary TKIP fix with WPA2's permanent AES implementation.
This question identifies WPA2 as the mandatory wireless encryption standard requiring AES for securing home networks, distinguishing it from legacy protocols like WEP and WPA.
Common mistake: Candidates often select WPA (A) because it is a recognized Wi-Fi standard, failing to recall that WPA used TKIP while WPA2 mandated AES.
Expert Analysis
Why the Answer Is Correct
WPA2 (Wi-Fi Protected Access 2) was introduced to permanently solve the vulnerabilities found in WEP and the temporary fixes in WPA. It mandates the use of Advanced Encryption Standard (AES) via CCMP, providing robust security required for modern home networks.
Why the Other Options Are Wrong
WPA (Option A) uses TKIP (Temporal Key Integrity Protocol), which was designed only as a temporary bridge for older hardware. WEP (Option D) relies on RC4 and is obsolete due to critical flaws. TKIP (Option B) is an encryption protocol itself, not the overarching technology standard that mandates AES.
Community Comment Notes
The community consensus correctly identifies WPA2 as the answer. As Roattana noted, "WPA2... mandated the use of AES" while WPA relied on TKIP. This aligns with official vendor documentation regarding Wi-Fi security standards.
Exam Strategy
Always associate WPA2 with AES and WPA with TKIP when answering certification questions about wireless encryption history and requirements.
Frequently Asked Questions
Why does WPA use TKIP instead of AES?
Is WEP still considered secure for home networks?

Roattana 👍 1 Answered C• WPA2 (Wi-Fi Protected Access 2) mandated the use of AES (Advanced Encryption Standard) to provide strong security for wireless networks. • WPA originally relied on TKIP (Temporal Key Integrity Protocol) as a temporary fix for older hardware. • WEP is an obsolete, highly insecure protocol that used the RC4 cipher.
