VMware Cloud on AWS Specialist — Question 16

Which statement is true regarding how vSphere High Availability (HA) provides rapid recovery from outages in VMware Cloud on AWS?

Answer options

• A. Sphere HA restarts virtual machines if their host becomes isolated on the VMware vSAN network.
• B. vSphere HA restarts impacted virtual machines on another host when an application fails.
• C. vSphere HA is enabled by default in VMware Cloud on AWS but can be disabled or modified.
• D. vSphere HA restarts impacted virtual machines (VMs) on another host when a VM stops sending heartbeats or the VM process fails (vmx).

Correct answer: A

Explanation

Option A is correct because vSphere HA specifically restarts VMs when their host is isolated, ensuring minimal downtime. Option B is incorrect as it does not accurately reflect HA's primary function in this context. Option C is misleading since HA's default status may vary depending on specific configurations. Option D, while related to HA, does not address the isolation scenario that A covers.
