According to the IEEE 802.11 standard, what is one structural difference between a MAC Protocol Data Unit (MPDU) and a MAC Management Protocol Data Unit (MMPDU)?

A. The MPDU frame's FCS field is 4 bytes, while the MMPDU frame's FCS field is 8 bytes.

B. The MMPDU frame body is limited to 300 bytes, whereas the MPDU frame body can carry up to 2304 bytes.

C. The MPDU header always places the BSSID in the first address field, but in the MMPDU the BSSID can be found in any of the address fields.

D. An MMPDU header may only contain three address fields, but an MPDU may have four address fields.

E. Both the MPDU and MMPDU have a QoS Control (QC) field, but all bits of the MMPDU's QC field are always 0.

When an originator QoS STA initiates a BlockAck agreement with a recipient QoS STA, what is the first frame sent by the originator?

A. BlockAckSetupReq

B. BlockAckReq

C. ADDBA Request

D. BlockAckPolicyReq

E. ActionBAReq

What is indicated to a QoS AP when a QoS STA sets U-APSD Flag bits to 1 in (Re) Association frames?

A. Which access categories are both trigger-enabled and delivery-enabled

B. Which user priorities require use of a TSPEC

C. Which access categories require admission control

D. Which user priorities are mapped to access categories

E. Which access categories are scheduled

ABC Company's WLAN administrator is getting complaints from one user that his WLAN throughput is sluggish compared to other users in his area. The administrator takes his diagnostics laptop, which has a wireless protocol analyzer installed, to the area where the complaining user works. The administrator uses the PING utility to test connectivity from the complaining user's wireless client station to another wireless client station across the closest access point, while capturing the wireless frames. The administrator sees what is displayed in this screenshot.

From this screenshot, which statements can you conclude to be TRUE that are related to the complaining user's throughput problem? (Choose 2)

A. The complaining user's WLAN client utilities are configured with a small fragmentation threshold.

B. The complaining user's station is retransmitting fragments many times likely due to nearby RF interference.

C. The access point and other stations are using ERP-OFDM modulation, and the complaining user's wireless client station is using HR/DSSS modulation.

D. The complaining user's wireless client station should be using RTS/CTS as a protection mechanism, but it is not.

E. The access point is not signaling for protection (Protection = no) in the Beacons, but it should be.

Given: There are many differences between analyzing wireless and wired networks. In a wireless network, there is no guarantee that one station can hear another station's transmissions. If no corrective actions are taken nor corrective mechanisms implemented when a "hidden node" problem exists, which measurable statistics parameter will likely increase in a wireless protocol analyzer?

A. Duration value

B. Retransmission Count

C. Contention Window

D. Authentication Failure

E. BlockAck Reset

F. ACK Timeout
