NEW QUESTION # 150
Refer to the exhibit.
An engineer determined that during a recent controller failure, some APs did not failover to their secondary controller based on the network design, which has sufficient licenses for all APs. The controllers are not in a mobility group but have A records for their hostnames in DNS. Which setting needs to be addressed?
- A. The controllers must be in the same mobility group.
- B. DNS hostnames are required to be FQDN.
- C. The secondary controller IP address is incorrect.
- D. The AP failover priority was not set high enough.
Answer: C
Explanation:
In the scenario described, where some APs did not failover to their secondary controller despite having sufficient licenses, the issue likely lies with the configuration of the APs to recognize the secondary controller.
Since the controllers are not in a mobility group but have A records for their hostnames in DNS, this suggests that they rely on DNS for AP discovery and failover. If APs are not failing over as expected, it could be due to an incorrect IP address configured for the secondary controller on the AP or within DNS. The exhibit shows that the "Secondary Controller" field has an IP address of "10.42.89.11", which should be verified against DNS records and actual controller settings to ensure accuracy.

NEW QUESTION # 154
Multiple WLCs are implemented in a high-availability configuration in a mobility group. APs are deployed with only a primary controller assigned. By default, which mobility group member controller do the orphaned APs join in the event of a failed controller?
- A. controller with the lowest percent of associated APs per license capacity
- B. controller with the least number of associated APs
- C. controller with the least CPU utilization over the last reporting period
- D. controller with the most available AP free license capacity
Answer: A
Explanation:
In a high-availability configuration, orphaned APs will join the controller with the lowest percentage of associated Access Points (APs) per license capacity by default. This ensures a balanced distribution of APs across the controllers in the mobility group, optimizing resource utilization and network performance.

- A. They have been configured with the spanning-tree bpdufilter disable command.
- B. They have been configured with the spanning-tree guard loop command.
- C. They have been configured with the spanning-tree bpduguard disable command.
- D. They have been configured with the spanning-tree guard root command.
- E. They have been configured with the spanning-tree bpdufilter enable command.
- F. They have been configured with the spanning-tree bpduguard enable command.
Answer: D
NEW QUESTION # 157
Refer to the exhibit.
What is the main reason why the Wi-Fi design engineer took a different approach than installing the APs in the offices, even though that installation provides better coverage?
- A. power supply considerations
- B. antenna gain
- C. aesthetics
- D. transmit power considerations
Answer: D
Explanation:
The decision to avoid installing APs directly in offices is likely due to transmit power considerations. Placing APs within offices could lead to excessive coverage for small areas, causing interference with other APs and reducing overall network performance. By placing them in common areas like corridors, engineers can ensure more uniform coverage across larger spaces while managing transmit power more effectively for optimal performance.

NEW QUESTION # 158
An AP is receiving 802.11 packets on its 802.11a radio with an RSSI value of -77 dBm. The current AP is part of an AP group that has been assigned an RF profile with RX-SOP set to Medium for 802.11a. Which action does the AP take with the packets?
- A. All frames are classified as non-Wi-Fi frames and are not decoded by the 5 GHz radio.
- B. All frames are classified as non-Wi-Fi frames and are not decoded by the 2.4 GHz radio.
- C. Frames are decoded by the 5 GHz radio.
- D. Frames are decoded by the 2.4 GHz radio.
Answer: C
Explanation:
An RSSI value of -77 dBm is within the range that a 5 GHz radio can receive and decode, provided it's not below the RX-SOP threshold set for the RF profile. Since the RF profile is set to Medium for 802.11a, which operates in the 5 GHz band, the AP's 5 GHz radio will decode the frames.
NEW QUESTION # 159
What causes the most signal attenuation, based on the wireless design tools?
- A. glass wall
- B. cinder block wall
- C. metal door
- D. office window

NEW QUESTION # 160
An engineer in a branch office that does not have a wired backhaul must ensure that local clients can be switched locally and authenticated centrally. In which mode must the AP be configured?
- A. MAP
- B. RAP
- C. Cisco FlexConnect
- D. Flex+Bridge
Answer: C
Explanation:
Cisco FlexConnect mode is designed for branch offices that lack a wired backhaul. It allows APs to switch client data traffic locally while still performing client authentication centrally. This mode provides the flexibility needed for branch deployments, ensuring that client traffic is handled efficiently even if the WAN link to the central site is down. References: Cisco FlexConnect technical documentation and Designing Cisco Enterprise Wireless Networks (ENWLSD) training.

- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
So max 2 will be supported on an AP.

Answer: C
NEW QUESTION # 163
An engineer must decide the cell overlap for a wireless voice deployment. Which Cisco measurement recommendation should be considered?
- A. The measurement should be done on the 2.4-GHz band.
- B. The edge of the cell should be -67 dBm.
- C. The edge of the cell should be below 35 RSSI.
- D. One AP should be deployed per 3000 square feet.
Answer: B
Explanation:
NEW QUESTION # 164
A university lecture hall has a Cisco wireless high-density network with this configuration:
- 5 GHz only
- 20-MHz channels
- UNII-1, UNII-2, and UNII2-E channels
- TPC minimum = 8
- TPC maximum = 14
The lecture hall is 200 feet by 100 feet and has 16 Cisco APs that use directional antennas.
Which feature must be included in the design to mitigate and reduce high-channel utilization from rogue APs?
- A. 802.11w
- B. DFS detection
- C. RxSOP
- D. band select
Answer: C
Explanation:
RxSOP allows the APs to ignore weaker signals, effectively reducing the impact of neighboring APs and potential rogue APs on the network. By adjusting RxSOP, APs can be made less sensitive to weak signals, which helps in reducing interference and improving overall network performance.
