What action should a technician take to ensure high availability for a VM?

• A. Increase the RAM allocation
• B. Take a snapshot of the original VM
• C. Clone the VM
• D. Run a load balancer

Answer: (B)

Taking a snapshot of the original VM is a prudent action to support high availability because it creates a complete point-in-time copy of the current state of the virtual machine. This includes the VM's current operating system state, applications, and data. In the event of a failure, this snapshot can be quickly restored, allowing for minimal downtime and swift recovery of the VM. It provides a safety net that ensures the VM can be reverted to a known good condition if issues arise, thus supporting continuity of service.

Other actions, while beneficial in their own contexts, do not directly address high availability in the same manner. Increasing RAM allocation may improve performance but does not ensure that the VM will remain accessible during an outage. Cloning the VM creates a separate instance, which can help with load distribution but doesn't directly prevent downtime for the original VM. Running a load balancer can distribute incoming traffic across multiple VMs, contributing to an overall resilient architecture, but it does not guarantee the availability of a single VM on its own. In this context, the snapshot is the most effective action to enhance the high availability of the VM specifically.
