Question # 35

An engineer has designed an anchor redundancy for guest clients connecting to SSID with auto-anchor configured. After adding a second Anchor WLC under the SSID mobility anchor list, clients are load-balanced between existing and new anchors instead of having one anchor as active and the other one as standby. Which feature should be included in the design that will be configured on the WLC running

8.1 or above to ensure anchor redundancy?

A.

Auto-Anchor Foreign Mapping

B.

AP groups

C.

Guest Anchor Priority

D.

802.11r

Question # 39

A customer has this wireless design:

• two Cisco Catalyst 9800 Series wireless controllers that are configured in a high-availability SSO cluster to manage the APs in a local office network

• 100 APs in local mode that are registered to the high-availability cluster

• one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ

• a CAPWAP tunnel in UP state between the high-availability cluster and the anchor WLC

The customer wants the anchored traffic to remain up if a single WLC in the high-availability cluster fails. How must this requirement be incorporated into the design?

A.

Configure the APs with the high-availability cluster as the primary base.

B.

Deploy EMC APs as anchors and configure a high-availability cluster.

C.

Create a separate EoIP tunnel for each WLC in the high-availability cluster.

D.

Configure the mobility MAC address for the high-availability cluster.
