Question: 2
Given: An ingress frame arrives on the Ethernet port of an autonomous AP marked with an IEEE
802.1D user priority value.

B. Network Control
C. Video
D. Voice
E. Best Effort
F. Excellent Effort
Answer: B, D
Question: 3
Given: When the delayed Block Ack policy is used between two QoS STAs, the recipient must
respond to a BlockAckReq frame with an ACK frame. The recipient must then send its BlockAck
response frame in a subsequently obtained TXOP.
Once the contents of the BlockAck frame have been prepared, the recipient must
_______________.
A. Send the BlockAck response frame to the originator in the earliest possible TXOP using the
highest priority AC.
B. Send an ATIM to the originator signifying that the BlockAck response frame is ready for
transmission.
C. Include the TID of the BlockAckReq in the next TXOP Request to the HC.
D. Wait for one PIFS after the next Beacon and transmit the BlockAck response to the originator
using the same AC as the BlockAckReq frame.
Answer: A
Question: 4
A QoS STA obtains a TXOP for an access category (AC) after what two parameters are met?
A. After a scheduled service period ends
B. The medium is idle at the AIFS[AC] slot boundary
C. The backoff time for that AC has expired
D. After a Block ACK Response

Question: 5
When using a protocol analyzer to capture conversations over a WLAN, you may often encounter
encrypted data frames. Most WLAN protocol analyzers have a feature that allows the analyst to
save and reload the captured frames into memory at a later time. Using this functionality, what
task can be performed?
A. When IEEE 802.1X/LEAP is being used as the WLAN security mechanism, the authentication
response frame can be replayed from a saved trace file at a later time to successfully
authenticate a hacker.
B. If a user name and password for an IEEE 802.1X/EAP-TTLS security implementation can be
obtained through social engineering tactics, the user name and password can be entered into
the analyzer to decrypt the frames from a saved trace file.
C. An analyst can search through the captured frames looking for RADIUS frames that will
disclose the user’s password.
D. Encrypted frames may be decrypted offline, after they are captured, by entering a WEP key or
WPA passphrase into the analyzer.
Answer: D
Question: 6

F. A Controlled Access Phase (CAP) burst
Answer: A, B, C
Question: 10
Many autonomous access points support IEEE 802.1Q VLAN tagging. When analyzing a WLAN
system using IEEE 802.1Q tags, where can the VLAN tag number be seen?
A. In the Sequence Control field of the MSDU
B. In the PLCP header’s Service field
C. In the Frame Control field of the MPDU header
D. In the Ethernet header on the wired port of the access point
E. In the Beacon Management frame’s Capabilities fixed field
Answer: D
Question: 11
Given: ABC Company is implementing a QoS enabled infrastructure that will support both voice
and data. The WLAN controller is connected to one of three core layer-3 Ethernet switches. Each
core layer-3 Ethernet switch has multiple edge layer-2 Ethernet switches attached. Lightweight
APs are connected to all edge layer-2 Ethernet switches. The WLAN controller is on subnet
10.1.1.0/24, and the APs are on numerous other subnets. The APs are connected to the WLAN
controller via LWAPP tunnels.
When IEEE 802.11 frames arrive at a lightweight AP from a QoS STA that need to be sent to the
WLAN controller, which bits can the AP mark to signal the layer-2 and layer-3 Ethernet switches
to use higher priority processing?
A. The Ethernet frame’s 802.1Q priority tag bits
B. The IP header’s TOS bits
C. The IEEE 802.11 frame’s QoS Control bits
D. The LWAPP header’s C bit
E. The UDP header’s PRI bits
Answer: A, B
