Question #2
An administrator creates a cluster by joining a Medium sized VMware Cloud Foundation (VCF) Operations for Logs node to an existing Medium sized single-node deployment. The secondary node of the cluster fails, degrading the functionality of VCF Operations for Logs. What action should the administrator take to create a healthy active cluster?
Correct answer: C
Explanation
In VMware Cloud Foundation (VCF)Operations for Logs, clusters require aminimum of three healthy nodesto function in a fully active and resilient state. When a cluster is deployed with only two nodes (primary + one secondary), the environment does not meet the minimum recommended requirement. If the secondary node fails, the cluster becomes degraded and functionality is reduced. The correct remediation is: Rebuild the failed secondary nodeso that the cluster can return to a healthy state. After rebuilding, the node must be rejoined to the primary using theManagement # Clusterworkflow (secure token, IP/hostname of primary, etc.). Why not the other options? A. Scale up to Extra Large##Scaling up affects resource capacity (vCPU, RAM, disk) but does not solve the problem of missing nodes. B. Scale up to Large##Same reason as above, scaling up does not restore HA. D. Rebuild the secondary and add an additional node##While adding more nodes is a best practice (since HA clusters require three nodes), theminimum action requiredto restore a healthy active cluster is torebuild the failed node. Adding more nodes is optional for increased resiliency. Therefore, the immediate and verified answer is torebuild the failed secondary node.

Question #8
A virtual machine (VM) owner has requested to move a VM from one cluster to another. The following information has been provided: The VM cannot have downtime during the transfer. The same network is present on both clusters. The datastore that the VM is currently on is not present in the destination cluster. What step should the administrator perform to move the VM?
Correct answer: C
Explanation
To move a VM to another cluster: Requirement: Zero downtime?? RequiresvMotion. Challenge: Datastore not shared?? RequiresStorage vMotion. The combined operation,Cross-Cluster vMotion with Storage vMotion, allows moving compute and storage at the same time, with no downtime. Other options: A. vMotion only?? Requires shared datastore, not available here. B. Backup/restore?? Causes downtime, not acceptable. D. Cannot be moved?? Incorrect; vMotion + Storage vMotion supports this.
