A company has an existing Cisco 5520 HA cluster using SSO. An engineer deploys a new single Cisco Catalyst 9800 WLC to test new features. The engineer successfully configures a mobility tunnel between the 5520 cluster and 9800 WLC. Clients connected to the corporate WLAN roam seamlessly between access points on the 5520 and 9800 WLC. After a failure on the primary 5520 WLC, all WLAN services remain functional; however clients cannot roam between the 5520 and 9800 controllers without dropping their connection.
Which feature must be configured to remedy the issue?
A. mobility MAC on the 5520 cluster
B. mobility MAC on the 9800 WLC
C. new mobility on the 5520 cluster
D. new mobility on the 9800 WLC
Refer to the exhibit. Assuming all links are functional, which path does PC1 take to reach DSW1?
A. PC1 goes from ALSW1 to DSW1
B. PC1 goes form ALSW1 to DSW2 to ALSW2 to DSW1
C. PC1 goes from ALSW1 to DSW2 to Core to DSW1
D. PC1 goes from ALSW1 to DSW2 to DSW1
In the topology above, we see DSW2 has lowest priority 24576 so it is the root bridge for VLAN 10 so surely all traffic for this VLAN must go through it. All of DSW2 ports must be in forwarding state. And:
+ The direct link between DSW1 and ALSW1 is blocked by STP.
+ The direct link between DSW1 and ALSW2 is also blocked by STP.
Therefore PC1 must go via this path: PC1 -> ALSW1 -> DSW2 -> DSW1.
Drag and Drop Question
An engineer creates the configuration below. Drag and drop the authentication methods from the left into the order of priority on the right. Not all options are used.
