   A manufacturing plant uses a CMX HA pair. The network team reports that the active CMX has been rebooted for maintenance, and the standby should have taken over. The HA dashboard shows the standby as 'Active' and the original primary as 'Standby'. However, location services are still not working for clients. Which verification step should you perform first?

   • ACheck the IP address of the virtual HA IP on the new active appliance
   • BVerify the NTP synchronization on the new active appliance
   • CCheck the license status on the new active appliance
   • DConfirm the DNS records for the CMX hostname

   A hospital runs a CMX HA pair with an active node in the main data center and a standby node in a disaster-recovery site. After a WAN link failure between the sites, the standby node does not take over, and the active node remains in a 'standalone' state. The network team confirms that the WAN link is now stable and both nodes can ping each other. Which action should be taken first to restore HA functionality?

   • ARestart the CMX services on the active node to force a fresh synchronization with the standby.
   • BPromote the standby node to active manually using the CLI.
   • CVerify that the HA heartbeat and synchronization traffic is permitted through the firewall between the two sites.
   • DReconfigure the standby node's IP address to match the active node's IP address.

   A retail chain deploys two Cisco Spaces Connector nodes in a cluster behind a load balancer. The load balancer health check fails intermittently for one node, and the connector dashboard shows that node as 'inactive'. The other node remains active and handles all traffic. Which step should be taken to diagnose the intermittent health-check failure?

   • AReboot the inactive connector node to force it to rejoin the cluster.
   • BDisable the health check for that node and rely on the active node only.
   • CIncrease the load balancer health-check interval to reduce false positives.
   • DCheck the connector node's certificate validity and its trust relationship with the load balancer.

   A company has a Cisco Spaces Connector cluster of three nodes behind a load balancer. One node is consistently marked 'down' by the load balancer health check, but the other two nodes are healthy. The administrator checks the node's local services and finds that the connector service is running. What should the administrator check next?

   • ACheck the node's certificate expiration date.
   • BVerify that the node's firewall allows health-check traffic from the load balancer on the configured port.
   • CRemove the node from the cluster and re-add it.
   • DRestart the connector service on the node to refresh its state.

   A government agency runs a Cisco Spaces Connector cluster of three nodes. The cluster status shows Node A as 'Active', Node B as 'Standby', and Node C as 'Unreachable'. The admin discovers that Node C's certificate has expired. The agency needs to restore Node C to the cluster with minimal disruption. Which recovery procedure should be followed?

   • AReboot Node A to force a failover to Node C
   • BRenew the certificate on Node C and restart the connector service
   • CCopy the certificate from Node A to Node C
   • DRemove Node C from the cluster and re-add it with a new certificate
