• Question 142:

  A customer has restricted the AP and antenna combinations for a design to be limited to one model integrated antenna AP for carpeted spaces and one model external antenna AP with high gain antennas for industrial, maintenance, or storage areas. When moving between a carpeted area to an industrial area, the engineer forgets to change survey devices and surveys several APs. Which strategy will reduce the negative impact of the design?

  A. Resurvey and adjust the design.

  B. Deploy unsurveyed access points to the design.

  C. Deploy the specified access points per area type.

  D. Increase the Tx power on incorrectly surveyed access points.

  Correct Answer: A

• Question 143:

  What is the attenuation value of a human body on a wireless signal?

  A. 3 dB

  B. 4 dB

  C. 6 dB

  D. 12 dB

  Correct Answer: A

• Question 144:

  A. N+1 solution without SS0

  B. N+1 with SSO

  C. N+N solution without SSO

  D. N+N with SSO

• Question 145:

  Refer to the exhibit.

  

  An enterprise is using wireless as the main network connectivity for clients. To ensure service continuity. a pair of controllers will be installed in a datacentre. An engineer is designing SSO on the pair of controllers. What needs to be included in the design to avoid having the secondary controller go into maintenance mode?

  A. The Keep alive timer is too low. which causes synchronization problems.

  B. The connection between the redundancy ports is missing.

  C. The redundancy port must be the same subnet as the redundancy mgmt.

  D. The Global Configuration of SSO is set to Disabled on the controller.

  Correct Answer: B

• Question 146:

  How does AP failover priority for access points function when configured with priority 1 or 4?

  A. When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

  B. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

  C. When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.

  D. When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.

  Correct Answer: B

• Question 147:

  Campus users report a poor wireless experience. An engineer investigating the issue notices that in high-density areas, the wireless clients fail to switch the AP to which are automatically connected. This sticky client behavior is causing roaming issues. Which feature must the engineer configure?

  A. Load balancing and band select

  B. optimized roaming

  C. Layer 3 roaming

  D. Layer 2 roaming

  Correct Answer: B

• Question 148:

  Why is 802.11a connectivity reduced in an X-ray room?

  A. X-rays create significant non-Wi-Fi interference on the 802.11a band.

  B. X-rays impact the 802,11a UNll-2 channels that cause access points to dynamically change channels.

  C. X-rays within these rooms cause multipath issues.

  D. X-ray rooms exhibit increased signal attenuation.

  Correct Answer: D

• Question 149:

  B. Sniffer

  C. Monitor

  D. SE-connect

  Correct Answer: D

• Question 150:

  A. Flexconnect

  B. MAP

  C. RAP

  D. Local

  Correct Answer: B
