VMware Certified Professional - Data Center Virtualization (VCP-DCV) Practice Exam

What action would ensure all virtual machines migrate automatically in a cluster?

1. Deselect the virtual machine from VM Overrides.

2. Add all virtual machines to the VM Overrides.

3. Change Response for Host Isolation to Use Cluster Settings.

4. Change the Automation level to Use Cluster Settings.

The correct answer is: Change the Automation level to Use Cluster Settings.

To ensure that all virtual machines within a cluster migrate automatically, changing the Automation level to Use Cluster Settings is essential. This action aligns the virtual machines with the cluster-wide policies regarding automation. When the automation level of a virtual machine is set to follow the cluster settings, it inherits the cluster’s automation policies, which manage the behavior of virtual machines in relation to host availability, load balancing, and resource allocation. By applying cluster settings, virtual machines can take advantage of features such as DRS (Distributed Resource Scheduler), which automates the placement and migration of virtual machines based on resource availability and usage. This means that if any host in the cluster becomes unavailable, the cluster will automatically migrate the virtual machines to other hosts, ensuring high availability and optimized performance. In contrast, actions such as deselecting a virtual machine from VM Overrides or adding all virtual machines to VM Overrides could limit the effectiveness of cluster-wide management. Likewise, merely changing the response for host isolation without adjusting the automation level wouldn't facilitate automatic migrations in the event of host failures or overloads. Therefore, leveraging the cluster's automation settings is key to achieving seamless and automatic VM migrations across the cluster.
