CWAP-402 Exam Training Practice Tests (CWNP Certified Wireless Analysis Professional)]

Question 1

When evaluating modulation and coding schemes, you must determine the best coding rate available. In 802.11 MCS tables, what is the best coding rate from the perspective of highest data rates?

A. 2/3 B. 5/6 C. 3/4 D. 1/2

Correct Answer: B

Question 2

You want to simplify viewing frames of a particular type in Wireshark.
What is used to specify frames for colorization?

A. Filters are used to define the frames that should be colorized B. Automated protocol analysis is used and no additional options may be specified C. Custom code must be written and the binaries recompiled D. A scripting language is available to modify the code before recompilation

Question 3

You have received reports of performance problems in a BSS. One specific user is indicating that her downloads are taking a very long time compared to other users around her. You want to determine if the AP is sending frames multiple times to get through to the user's computer.
Where should you monitor with the protocol analyzer to see retries from the AP in this scenario?

A. Very near the AP B. Directly in the middle of the AP and client STA C. Very near the client STA D. Capture from another AP in another BSS

Correct Answer: A

Question 4

What element was added to the general frame of 802.11 with the 802.11e amendment and the 802.11-2007 rollup?

A. RSN-IE B. QoS Control C. Address 4 D. HT Control

Correct Answer: B

Question 5

You are troubleshooting throughput problems for a WLAN cell. The cell is provisioned with an 802.11ac dual-band AP. Users connected with both 5 GHz and 2.4 GHz connections are reporting performance problems. The AP settings are properly optimized. No interface issues have been detected (either co-channel interference or non-Wi-Fi interference) and the number of associated users is low.
What should you analyze to resolve the issue?

A. The 2.4 GHz radio configuration B. the Ethernet uplink and the network infrastructure C. The antennas used on the client devices D. The 5 GHz radio configuration

Correct Answer: B

Question 6

Recently, three rogue APs have been connected to the network and later discovered. You want to prevent future rogue AP installations as much as possible.
What is the first step to eliminating or reducing rogue APs on the network?

A. Define a direct policy that stipulates the ramifications of installing unauthorized devices B. Create a hash of the MAC addresses of all authorized devices and continually scan for non-matching hashes C. Enable rogue detection in the existing authorized APs D. Use IPSec between every AP and the network infrastructure

Correct Answer: C
