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

What does the Response for Host Isolation configuration impact?

1. Automated VM restart in case of power failure.

2. How virtual machines behave during network isolation.

3. Privileges assigned to the virtual machine.

4. Number of virtual CPUs allocated to the virtual machine.

The correct answer is: How virtual machines behave during network isolation.

The Response for Host Isolation configuration is crucial because it directly affects how virtual machines respond during instances of network isolation. When a host becomes isolated from the network, the configuration dictates the actions that the virtual machines on that host will take. For example, if a virtual machine is configured to power off or suspend during host isolation, it will do so in accordance with the specified settings. This feature is important for maintaining the integrity and availability of services running on virtual machines. Depending on the configuration, some virtual machines may continue to run as they lose connectivity to their management environment, while others may halt operations to prevent further issues, like split-brain scenarios, where two clusters might try to manage the same VM. Therefore, the response to host isolation is essential for ensuring the correct operational behavior of virtual machines during such events. The other options relate to aspects of virtual machine operations, such as resource management or privileges, but do not pertain to the specific impact of host isolation response settings.
