   A retail chain runs Cisco Spaces Connector as a cluster of three nodes behind a load balancer. After a certificate renewal on the primary node, the cluster status dashboard shows the other two nodes as 'Unreachable'. The load balancer health checks still pass for all three nodes. What is the most likely cause of the cluster communication failure?

   • AThe renewed certificate is not trusted by the other cluster nodes
   • BThe cluster nodes have different NTP time settings
   • CThe load balancer is not forwarding cluster traffic to the standby nodes
   • DThe cluster nodes are running different versions of the connector software

   In a Cisco Spaces Connector cluster, what is the purpose of load balancing among cluster members?

   • ATo reduce the number of connectors needed by combining their processing capabilities.
   • BTo ensure that each connector processes the same data to provide redundancy.
   • CTo allow each connector to independently decide which data to send to Cisco Spaces.
   • DTo distribute the data processing workload across multiple connectors to improve performance and scalability.

   A logistics company runs a two-node Cisco Spaces Connector cluster. The cluster status shows Node A as 'Active' and Node B as 'Standby', but the 'Last Sync' time on Node B is several hours old. The connector service on Node B is running, and the load balancer health checks pass. Which log or status command should you examine first to diagnose the synchronization issue?

   • AThe cluster communication logs on Node B
   • BThe load balancer access logs
   • CThe certificate store on Node A
   • DThe system event log on Node A

   A company runs a Cisco Spaces Connector cluster of three nodes behind a load balancer. The cluster is configured for HA, but the load balancer health check is failing for all three nodes intermittently. The connector service is running on all nodes, and the cluster status shows all nodes as 'active'. What is the most likely cause of the health-check failures?

   • AThe load balancer's health-check interval is too short, causing false positives.
   • BThe connector nodes are overloaded and cannot respond to health checks.
   • CThe cluster is in a split-brain state, causing the nodes to be unresponsive to health checks.
   • DThe load balancer is configured to use HTTPS health checks, but the connector nodes' certificates are not trusted by the load balancer.

   A university's CMX HA pair is working normally. The admin wants to verify that the standby is truly ready to take over in case of a failure. Which verification method provides the most reliable confirmation of HA readiness?

   • ACheck the HA status dashboard and confirm the standby shows 'Synchronized'
   • BVerify the standby's license is active
   • CReview the standby's system logs for any errors
   • DPing the standby's management IP address
