   A vSAN Stretched Cluster has been running for several months. After a brief network outage between the two zones, the administrator notices that the vSAN health checks report 'Data resynchronization' in progress. The resync is taking longer than expected, and the administrator wants to identify the cause. Which log or health check should the administrator examine first to determine why the resync is slow?

   • AThe vSAN performance service metrics for the witness host.
   • BThe ESXi host logs on the witness host to check for witness-related errors.
   • CThe vCenter alarm 'vSAN object health' to see if any objects are degraded.
   • DThe vSAN health check 'Network performance' to verify the inter-site link bandwidth and latency.

   A vSAN Stretched Cluster has two zones connected via a 10 Gbps link. The witness host is at a third site connected via a 1 Gbps link. The administrator notices that the vSAN health check 'Network latency' reports a warning for the witness host, but the inter-site link is healthy. The administrator also observes that write operations are slower than expected. What is the most likely cause of the write performance issue?

   • AThe data nodes are configured with the wrong MTU size, causing fragmentation.
   • BThe witness host is running on a VM with insufficient CPU resources.
   • CThe 1 Gbps link to the witness host is a bottleneck for write operations because the witness must acknowledge writes.
   • DThe inter-site link is not configured with jumbo frames, causing increased overhead.

   A VCF administrator is designing a vSAN Stretched Cluster for a new deployment. The cluster will have two availability zones, each with four hosts. The administrator wants to ensure that the cluster can tolerate the failure of an entire availability zone. What is the minimum number of fault domains required for this configuration?

   • AThree fault domains, one for each availability zone and one for the witness host.
   • BOne fault domain for all hosts, with the witness as a separate component.
   • CTwo fault domains, one for each availability zone.
   • DFour fault domains, one for each host in the cluster.
