A. Client stationsbroadcasting with too much power

B. Access points broadcasting with too little power

C. Client stations too close in proximity to each other

D. Data frames too large for the physical environment

E. Large 802.11 cells with physically distributed stations

F. Obstacles between client stations causing attenuation

정답: E,F

문제2

What problems may occur when there are hidden nodes in the BSS?

A. Duration values vary widely in each data frame.

B. Use of frame fragmentation with fragment bursts.

C. Excessive use of null data frames.

D. High retransmission count for a subset of client stations.

E. Increase in downlink (transmitted by AP) frame retries.

정답: D

문제3

What statements about the SSID are true? (Choose 2)

A. The SSID is a pseudo-random number assigned to each client by an AP.

B. The SSID is an alphanumeric value assigned to device manufacturers by the IEEE.

C. The SSID is a security session identifierused in RSNs.

D. The SSID is an alphanumeric value with a maximum length of 32 octets.

E. When configuring a new network, creating an SSID is optional.

F. The SSID must be included in an association request frame.

정답: D,F

문제4

When using an RF splitter to connect one transceiver to sector antennas loss is incurred.
What is this loss called?

A. Intentional loss

정답: B

문제6

ABC Company has a 2.4 and 5 GHz WLAN deployment. DFS functionality is enabled as required by the regulatory domain andAPs use DFS channels as long as radar is not detected. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.
Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the users roam throughout the building. All APs have 2.4 and 5 GHz radios enabled with transmit power adjusted to accommodate relatively similar cell sizes.
This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause of the unpredictable client band selection behavior?

A. Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36-48.

B. 5 GHz frequencies offer better RF penetration than 2.4 GHz, but2.4 GHz offers more voice call capacity and lower latency than 5 GHz.

C. The client's band selection algorithm prefers 5 GHz, butband steering behavior usually steers 75-85% of client devices to 2.4 GHz.

D. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holesas it moves through the network.

정답: D

문제7

B. 48

D. 1
