Question 7
Seems that options C and D are both correct, since both Non-HT Legacy and HT-Mixed PPDUs contain the L-SFT, L-LTF, and L-SIG fields, enabling Non-HT stations to detect the PPDU and acquire the carrier frequency and timing.

Question 13
The answer says that QoS-related action frames are always category 1, but it indicates that A. (which says category 0) is the correct answer.

Question 14
"FH [i]Hoping[/i] Pattern" -- should be
"FH [i]Hopping[/i] Pattern"

Question 18
All options that should say "ACK" instead say "AC".

Question 18 (cont'd)
CWNP texts say that 802.11 STAs do not detect collisions, but they do identify corrupted frames. Perhaps this question's answer options need to be reworded.

Question 28
Option C says
"Enough to [i]full[/i] a single TXOP" -- should be
"Enough to [i]fill[/i] a single TXOP"

Chapter 3, QoS Control Field section, paragraph 12, last sentence (reading the Kindle version, so I don't know the page number).

It states that a TXOP limit of [b]1[/b] restricts transmission during a TXOP to a single MPDU.

It should say that a TXOP limit of [b]0[/b] restricts transmission during a TXOP to a single MPDU.

Question 18
Options A and E are identical. Based on the surrounding options and the answer, I believe that option E should say that individual MPDUs in the A-MPDU are encrypted individually.

Question 29
The last word of the sentence should be A-MPDU, not A-MPD.

Question 4 typo
Option B "DSSS-OFMD" should probably be "DSSS-OFDM", unless you're really throwing a curveball here.

Question 49
Options B and D are Voice and Video, and are the correct answers. However, the test says A and D are correct.

Last sentence, typo -- [i]vendor-dependant[/i] should be [i]vendor-dependent[/i]

Likewise, The last word in the "TCP Request Frame and TCP Report Frame" is [i]dependant[/i] instead of [i]dependent[/i].

Figure 9-36 where is the ANonce? Diagram just looks wrong.
Figure 9-37 Step 4 Where's PMK-R1?
Figure 10-16 RBG should be RDG
