   An administrator is verifying the HA status of a CMX pair. The 'show cmx ha status' command shows the active node as 'active' and the standby node as 'standby', but the 'last sync' time is several days old. What does this indicate?

   • AThe standby node is in a 'standby' state, so it does not need to synchronize.
   • BThe standby node has not received updates from the active node for several days, so failover may result in data loss.
   • CThe HA pair is healthy; synchronization only occurs during failover.
   • DThe active node is not generating any new data, so synchronization is not needed.

   Which network connectivity issue can prevent CMX failover from working correctly?

   • AThe standby node has a different default gateway than the active node.
   • BThe active and standby nodes cannot communicate on the HA heartbeat interface.
   • CThe active node cannot reach the wireless LAN controller.
   • DThe standby node cannot reach the internet.

   What is the typical failover behavior in a CMX high availability pair when the active node becomes unreachable?

   • AThe standby node immediately becomes active without any delay or verification.
   • BThe standby node takes over the active role after a detection timeout and verification that the active node is truly down.
   • CThe network administrator must manually promote the standby node using the CLI.
   • DBoth nodes continue to operate independently and clients are load-balanced between them.

   A CMX HA pair is configured with the active node in a data center and the standby node in a branch office. The standby node has sufficient CPU and memory, but the active node's database is large. The administrator notices that the standby node's disk usage is at 95% during synchronization. What is the most likely impact on HA?

   • ASynchronization will fail or be incomplete, preventing the standby from becoming a valid failover target.
   • BThe active node will throttle its synchronization to reduce disk usage on the standby.
   • CThe standby node will continue to synchronize but will be slower to take over.
   • DThe standby node will automatically delete old data to make room for the synchronization.

   A global retailer runs a Cisco Spaces Connector cluster of five nodes across two data centers (three in DC1, two in DC2). The cluster status shows all nodes as 'Healthy', but the connector is not sending location data to Cisco Spaces. The admin suspects a quorum issue. Which configuration change would best ensure the cluster can maintain quorum even if one data center becomes completely isolated?

   • AMove all nodes to a single data center
   • BConfigure the cluster to require only two nodes for quorum
   • CAdd a witness node in a third location
   • DIncrease the number of nodes in DC1 to four
