質問 6

A customer has this wireless design:
- two Cisco Catalyst 9800 Series wireless controllers configured in a high-availability SSO cluster to manage APs in the local office network
- 100 APs in local mode and registered to the high-availability cluster
- one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ
- Cisco ISE for user authentication and authorization

（A）Send the AAA server accounting and authentication traffic from the anchor WLC.

（B）Send the AAA server accounting and authentication traffic from the high-availability cluster.

（C）Send the accounting traffic from the high-availability cluster and the authentication traffic from the anchor WLC.

（D）Send the accounting traffic from the anchor WLC and the authentication traffic from the high- availability cluster.

質問 8

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）Guest Anchor Priority

（C）802.11r

（D）AP groups

質問 10

Refer to the exhibit. An engineer is about to establish a mobility peer connection between a Cisco Catalyst 9800-CL version 16.10.1 e and Cisco AireOS 5520 version 8.8.120.0. The data path between the 9800-CL and AireOS 5520 is up, but its control path is down. Based on the configuration, what is the root of the issue?

（A）The data-link-encryption configuration is missing from the 9800-CL configuration.

（B）The certificate hash key is missing from the AireOS 5520 WLC mobility configuration, which causes the control path to be down.

（C）Encrypted mobility is being used in the 5520 configuration, which causes the control path to be down.

（D）CAPS is used to key in the MAC address in the IOS_XE configuration, which causes the control path to be down.
