An engineer is implementing a wireless design for a manufacturing company with a Catalyst
9800, a stack of two Catalyst 9300-48HX switches, and 9166 APs. Each AP must be named using the Zone-053424189-01X string where X is the area number. The engineer needs to connect the APs to the switch stack using PoE. How many APs must the engineer connect to the stack so that they run with full functionality?

• A. half of the ports on each switch
• B. all ports on all the switches
• C. all ports on switch 1 of the stack
• D. half the ports on switch 2 of the stack

A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers. Which configuration task fixes the issue?

• A. Enable AP fallback globally on the WLC.
• B. Use DHCP Option 43 and specify WLC in location A as primary.
• C. Change the AP Failover Priority to critical.
• D. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points.

An engineer is performing a Layer 1 passive wireless site survey utilizing a channel analyzer software in the 2.4 GHz spectrum. Which chart indicates the ratio of interference present during the duration of the capture?

• A.
  
• B.
  
• C.
  

A customer has an existing wireless network with a Cisco 9800 WLC high availability cluster and Cisco 9120 APs. The customer asks an engineer to perform a post wireless survey that includes a list of any non-802.11 devices on the 5 GHz band. The engineer performs the survey using an
802.11a/b/g/n/ac/ax WLAN adapter but did not use a spectrum analyzer. Which approach meets the requirements?

• A. Export a list of 802.11b interferers using the WLC and the RF ASIC embedded in the APs.
• B. Set the WLAN adapter to monitor mode and perform the analysis by using 802.11a.
• C. Set the WLAN adapter to monitor mode and perform the analysis by using 802.11b.
• D. Export a list of 802.11a interferers using the WLC and the RF ASIC embedded in the APs.

A university has three campus locations and the main data center. Each campus location has a Cisco Catalyst 9800-40 WLC that manages 600 APs. The data center has a Catalyst 9800-40 WLC, which serves as N+1 backup for each campus WLC. A consulting engineer must install four additional Catalyst 9800-40 WLCs to serve as high availability SSO pairs for each campus, but only two have been approved due to budget restrictions. Requirements: Data center WLC must always be available as N+1 backup, Campus1 WLC must operate with zero downtime, and in the event of multiple campus outages, the AP priority order is to support Campus3, Campus2, then Campus1. Which design approach must the consulting engineer take?

• A. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.
• B. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.
• C. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.
• D. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.
