To ensure VM high availability (HA) in the event of a node failure, the administrator must enable HA Reservation (Option B) in Prism Element.
High Availability (HA) in Nutanix ensures that VMs restart on another available node if the host they are running on fails.
Option A (Redundancy Factor 3) affects storage redundancy, not VM failover.
Option C (Protection Domains) is related to disaster recovery (DR), not local HA failover.
Option D (RF1 Storage Container) would reduce fault tolerance and is not recommended for production environments.

Wait, can HA really handle all that? Sounds too good to be true!

Redundancy Factor of 3 seems excessive for just one host failure.

Definitely need to set up a Protection Domain for this.

I vaguely recall something about RF1 storage containers, but I can't remember how they fit into VM migration scenarios.

Configuring a Protection Domain sounds familiar; I feel like it relates to VM availability during host failures.

I remember practicing with HA settings, but I'm not sure if "Enable HA Reservation" is the right choice here.

I think setting the Redundancy Factor to 3 might be overkill for just ensuring VMs can restart on another node.

This seems straightforward. Based on the question, the best option is to enable HA Reservation. That will ensure VMs can be automatically restarted on another node if the original host fails. The other choices like Redundancy Factor and Protection Domains don't seem as directly relevant to the specific requirement stated here.

Okay, let me think this through. If the goal is to ensure VMs can be restarted on another node, then I'm guessing the answer has to do with configuring some kind of redundancy or failover mechanism. I'd start by looking at the Redundancy Factor and HA Reservation options.

Hmm, I'm a bit unsure about this one. I know Prism Element has some HA features, but I'm not totally clear on the differences between the options like Redundancy Factor and HA Reservation. I'll need to review those in more detail.

This looks like a pretty straightforward question about ensuring VM migration and failover in Prism Element. I think the key is to understand the different options available for high availability.

I believe configuring a Protection Domain would be the best option to ensure VMs can be migrated and restarted in case of a single-host failure.

Haha, D) Configure an RF1 storage container? What is this, a joke? That would just make everything less redundant!

I'm not sure about Redundancy Factor, but I think enabling HA Reservation could also help meet the requirement.

I agree with Francene, having a Redundancy Factor of 3 would ensure VMs can be migrated and restarted on another node.

I was thinking B) Enable HA Reservation, but C) makes more sense. Protection Domains are the way to go for high availability.
