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 uses RC4 and is broken.
- ✗
WPA
Why it's wrong here
WPA uses TKIP/RC4, not AES-CCMP.
- ✓
WPA2
Why this is correct
WPA2 uses AES-CCMP per 802.11i.
- ✗
WPA3
Why it's wrong here
WPA3 uses GCMP-256, but the 802.11i standard defines WPA2.
Quick reference
Symmetric Encryption Algorithm Comparison
| Algorithm | Key Size | Block Size | Status | Notes |
|---|---|---|---|---|
| AES-128 | 128-bit | 128-bit | Current standard | NIST approved; WPA3, TLS |
| AES-256 | 256-bit | 128-bit | Current standard | Preferred for sensitive / govt data |
| 3DES | 112-bit effective | 64-bit | Deprecated (2023) | Replaced by AES |
| DES | 56-bit | 64-bit | Broken | Cracked in < 24 h; never deploy |
| ChaCha20 | 256-bit | Stream cipher | Current | TLS 1.3, WireGuard |
