A company operates a critical application on a single server. The server has a single power supply and a single network interface card (NIC). The administrator wants to improve the server's fault tolerance against hardware failures. Which set of hardware components should be added or replaced?

Add a second power supply and a second NIC

Add a second hard drive and configure RAID 0

What is the primary function of load balancing in a compute environment?

To distribute incoming workloads across multiple compute nodes to prevent any single node from becoming a point of failure.

To ensure that all compute nodes have identical data stored locally.

To increase the processing speed of individual compute nodes.

To provide a backup power source for compute nodes.

An organization runs a mission-critical application on a VM in a two-node hypervisor cluster. The cluster does not use shared storage; each host has local disks. The administrator needs to perform maintenance on Host A, which requires a reboot. The VM must remain available during the maintenance. Which compute-based fault tolerance technique should the administrator use?

Replicate the VM to Host B and then shut down the VM on Host A

Take a snapshot of the VM before rebooting Host A

Configure a failover cluster between the two hosts

Live migration of the VM to Host B

How does VM replication support recovery from compute failures?

By encrypting the VM's data to protect it from unauthorized access.

By creating a copy of the VM on another host that can be activated if the primary fails.

By storing multiple snapshots of the VM on the same host.

By increasing the CPU and memory resources allocated to the VM.

How do redundant fans contribute to compute fault tolerance?

They increase the airflow to allow higher CPU clock speeds.

They provide power to the system in case of a fan failure.

They prevent overheating by providing backup cooling if a primary fan fails.

They reduce noise by distributing the cooling load across multiple fans.
