Q: 4
What cipher suite is specified by the 802.11-2016 standard and is not deprecated?

My pick: C for CCMP. WEP and TKIP (A and B) are both considered insecure now, and EAP (D) isn't a cipher suite. CCMP is required by WPA2 per the 802.11-2016 standard. Pretty sure on this, but shout if you disagree.
Option C is the one that's not deprecated. CCMP is the mandatory suite in 802.11-2016, and WEP/TKIP are both long gone. Saw a similar question in some practice-anyone see it answered differently?
CCMP has to be it, since it's the encryption suite that's actually required by 802.11-2016. WEP and TKIP are both deprecated, D is just about authentication. I think C but feel free to correct me if I'm missing something from the standard.
Saw exactly similar question in official practice. It's C for sure.
D . EAP is widely used for authentication and keeps showing up in standards discussions, so I thought it might fit here. Not 100% on this one, but worth double-checking.
C . CCMP is the only cipher suite in the list that's still not deprecated under 802.11-2016. Saw this in both the CWNA official guide and some practice exams. Correct me if I'm missing something.
Good point about the difference-EAP (D) is all about authentication, not encryption. The question clearly wants the cipher suite, so C.
I get why some would pick B, since TKIP hung around for a while, but pretty sure C is the right move here. CCMP (option C) is based on AES and it's the mandatory suite that isn't deprecated by the 802.11-2016 standard. Still, if anyone has a source showing TKIP wasn't fully out yet in 2016, let me know.
B seems right to me, since TKIP was still referenced for a while and is used with WPA. I know it's less secure but thought it wasn't fully deprecated in the 2016 standard yet. Open to corrections though if I missed something technical.
B
