Cisco Designing Cisco Wireless Networks Sample Questions:

1. A customer wants a network engineer to design a Cisco wireless solution that will have redundancy through SSO and LAG. APs in the executive office must reassociate to the WLC as soon as possible in the event of a failure. The WLCs are located in a remote data center. The head office uses a WAN for connectivity with the data center. Which priority must be incorporated in the design to be assigned to the executive APs?

A) high
B) medium
C) low
D) critical

2. A network engineer must review the design for a Cisco wireless deployment at a hospital. The deployment will have two Cisco 9800 WLCs configured with SSO, one Cisco 9800 WLC joined to the SSO controllers using a mobility tunnel, and one Cisco 9800 WLC that will be used as a service/dev controller and not joined using a mobility tunnel. Which high availability option must be incorporated in the design to ensure that APs choose the service/dev controller last when trying to associate?

A) secondary
B) AP failover priority
C) primary
D) tertiary

3. A community bank has three campus locations and one HQ with the data center. Each campus has four Cisco Catalyst 9120 APs. Poor WAN uplinks cause impacted connectivity back to HQ, and each campus is planned to have its own EWC controller based on C9120 AP to keep traffic local. Guest WLAN will be routed locally.
Employee WLAN must be authenticated 802.1x PEAP via HQ ISE but can pass traffic locally once authenticated. HQ WLC will be the primary backup WLC for each WLC. Which design approach should the consulting engineer take?

A) One C9120 AP in each campus must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server to be added to EWC.
B) One C9120 campus AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC paired as mobility peer and configured as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN. The campus employee WLAN will need the guest anchor back to the HQ employee WLAN.
C) Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server added to EWC.
D) Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby with HQ WLC as N+1 backup. The campus guest WLAN will use the guest anchor to HQ WLC for guest VLAN access, and employee WLAN will need the HQ AAA server added to EWC.

4. During a post-deployment site survey, issues are found with non-Wi-Fi interference. What should the engineer use to identify the source of the interference?

A) Wireless intrusion prevention
B) Cisco spectrum expert
C) Network analysis module
D) Wireshark

5. A customer has multiple WLCs running in N+1 redundancy with APs load balanced between the WLCs. The customer performs AP failover testing between the WLCs and notices that some of the APs do not move back to their primary WLC after it recovers. What are two points that must be addressed in the design? (Choose two.)

A) APs failover priorities are set to Low.
B) DHCP Option 43 information is incorrect.
C) APs do not have their secondary WLC information configured correctly.
D) AP Fallback is not enabled on one of the WLCs.
E) APs do not have their primary WLC information configured correctly.
