An engineer must assess an existing company WLAN to determine the possibility for future IEEE
802.11ac Wave 2 wireless deployment. All access switches are Fast Ethernet-capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points?
(Choose two.)

• A. Replace the existing switches with gigabit switches with 10G uplinks.
• B. Replace the existing switches with mGig switches.
• C. Ensure that cable distances between access switches and APs are not longer than 55 meters.
• D. Ensure that cable distances between access switches and APs are not longer than 100 meters.
• E. Replace the existing wiring infrastructure with the CAT-7E wiring standard.

A customer has two Cisco WLCs configured in a SSO cluster. The wireless network supports a large warehouse. The customer purchases new iPads to replace legacy scanners. Both devices connect to a single SSID named Scanning by using WPA2 Personal. The customer wants to use a standards-based method for fast roaming on the new iPads. Which approach meets the scanner requirement and still supports the legacy scanners?

• A. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.
• B. Enable FT 802.1X and set Fast Transition to Adaptive for the Scanning SSID.
• C. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.
• D. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.

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 network engineer is designing a wireless network to support high availability. The network will need to support the total number of APs and client SSO. Live services should continue to work without interruption during the failover.
Which two requirements need to be incorporated into the design to meet these needs? (Choose two.)

• A. redundant WLC
• B. controller high availability pair with one of the WLCs having a valid AP count license
• C. back-to-back direct connection between WLCs
• D. WLC 7.5 code or more recent
• E. 10 sec RTT

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 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.
• B. 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.
• 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. 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.
