Question 1

Referencing the screenshot of an 802.11b Data frame, what does the "Version" field mean?

A. Version = 0 shows which type of fragmentation is being used on the wireless segment.
It can be either standard or compressed.

B. Version = 0 shows which version of 802.11 MAC header is in use. It can be either Standard or SNAP.

C. Version = 0 shows that the first revision of the 802.11 frame format is in use.

D. Version = 0 shows whether 802.1h or RFC1042 frame translation is being used between the wired and wireless sides of the access point.

Correct Answer: C

Question 2

A wireless LAN protocol analyzer utilizing a radio card compliant with IEEE 802.11a,
802.11b, and 802.11g standards will be able to perform which of the following tasks?

A. Recognize and decode 802.11-compliant FHSS access point transmissions in the 2.4 GHz ISM band.

B. Recognize and decode all 802.11g frames regardless of the modulation used at the physical layer.

C. Recognize and decode all protection mechanisms sent by a transmitter using CCK.

D. Recognize, decrypt, and decode unicast data frames encrypted with WPA-compliant
802.1X/EAP between stations and access points when an appropriate username and password combination is entered into the analyzer software.

E. Recognize and decode 802.11a, 802.11b, and 802.11g transmissions simultaneously.

F. Recognize and decode transmissions from 900 MHz Pre-DSSS system in order to report an intrusion to a centralized security console.

Correct Answer: C

Question 3

ABC Corp has just installed a single 802.11b access point into their medium-sized office environment. As the wireless LAN administrator at ABC Corp, you use a wireless protocol analyzer to troubleshoot the problem. You place your analyzer close to the access point, and capture some traffic from office users. Given the screenshot shown, which of the following statements offer the best explanation for the poor wireless LAN performance of ABC's new 802.11b wireless LAN?

A. There is likely a source of RF interference somewhere around the access point. This is causing many data frames to be retransmitted, so overall wireless LAN throughput has been greatly diminished.

B. A nearby 802.11b access point is operating on an adjacent channel causing a significant amount of corrupt frames within ABC's BSS. These corrupt frame fragments are congesting the channel on which ABC's wireless LAN is operating, thereby decreasing its throughput.

C. Due to an 802.11g client joining the BSS, protection mechanisms have been enabled in the BSS by the access point. These protection mechanisms greatly increase protocol overhead, thereby decreasing overall wireless LAN throughput.

D. One of the wireless LAN users has moved far enough away from the access point that his client station has begun transmitting frames at the minimum supported data rate. Even when a single user uses this rate for Data frames, throughput for the entire wireless LAN as a whole is slowed significantly.

Correct Answer: D

Question 4

When an access point sends an RTS frame, the duration field will contain an amount of time, measured in microseconds, equal to which of the following?

A. 1 DATA, 1 RTS, 2 SIFS, 1 DIFS, 1 ACK

B. 1 ACK, 1 CTS, 1 DATA, 3 SIFS

C. 2 ACK, 1 RTS, 1 DATA, 4 SIFS

D. 1 RTS, 1 CTS, 1 DATA, 2 ACK, 4 SIFS

Correct Answer: B

Question 5

James is a sales associate for ABC Company. Sitting at his desk, James can use the wireless LAN with no problems. James takes his laptop downstairs to ABC Company Engineering department. James finds that he cannot connect to the Internet or the company intranet, but his wireless LAN card utilities shows that he is associated to the wireless network. Engineers are reporting no network connectivity problems over the wireless LAN. When using a protocol analyzer, what will you most likely find as the cause of the problem?

A. ABC Company administrator has configured different security mechanisms for the Sales and Engineering departments.

B. James has a static IP configured on his laptop, and he has now roamed across a layer 3 network boundary.

C. ABC Company administrator has configured protocol filters on the Engineering department access points.

D. An ARP storm is consuming the wireless medium bandwidth making network connectivity almost impossible.

E. Someone has placed a rogue DHCP server on the Engineering network.

Correct Answer: B

Question 6

Which of the following information will a wireless LAN protocol analyzer capture if it can only capture Data Link information?

A. Null Function Data frames

B. Short Interframe Spaces

C. TCP SYN datagram

D. Sequence Control fields

E. Source IP Address

Correct Answer: A,D
