   A VCF Operations cluster has 4 nodes, and HA is enabled. The administrator notices that the cluster's HA status is 'Degraded' and one node is not participating in HA. The node is healthy and can communicate with the other nodes. What is the most likely cause of this issue?

   • AThe cluster's quorum settings are misconfigured.
   • BThe node's service distribution is not configured correctly.
   • CThe witness node is not reachable from the cluster.
   • DThe node's HA configuration is not enabled or is misconfigured.

   A VCF Operations administrator notices that a vCenter adapter is collecting data but the collection interval is longer than expected. The adapter's status shows 'OK', but the data is delayed by several hours. The vCenter Server is healthy, and the CloudProxy has sufficient resources. What is the most likely cause of this issue?

   • AThe adapter's collection interval is set to a value that is too long for the environment's requirements.
   • BThe adapter's endpoint credentials are incorrect, causing it to retry authentication before each collection.
   • CThe vCenter Server's API is throttling the adapter's requests due to high load.
   • DThe CloudProxy's certificate has expired, causing the adapter to use a fallback collection method.

   A VCF Operations cluster has HA enabled with a witness node. The cluster has 7 nodes. During a network outage, 3 nodes lose connectivity to the rest of the cluster and the witness. The remaining 4 nodes and the witness are healthy. After the network outage is resolved, the 3 isolated nodes rejoin the cluster. However, the administrator notices that the cluster's HA status is 'Degraded' even though all nodes are back. What is the most likely cause of this issue?

   • AThe cluster's quorum settings were changed during the outage.
   • BThe HA configuration is not fully synchronized across all nodes after the rejoin.
   • CThe 3 isolated nodes have different service distribution configurations.
   • DThe witness node lost its configuration during the outage.

   A VCF Operations administrator is troubleshooting a network adapter that is not collecting data. The adapter's status shows 'Endpoint unreachable'. The network device is reachable from the CloudProxy via ping, and the credentials are correct. What is the most likely cause of this issue?

   • AThe adapter's collection interval is set too high, causing timeouts.
   • BThe network device's API is not responding.
   • CThe adapter's endpoint URL is misconfigured, pointing to the wrong port or path.
   • DThe CloudProxy's certificate is not trusted by the network device.
