What is checkpointing in the context of application-level fault tolerance?

Creating a backup of the entire operating system.

Distributing application workloads across multiple servers.

Saving the application's state at regular intervals so it can be resumed from that point after a failure.

Encrypting application data to protect it from unauthorized access.

What is live migration in the context of virtual machines?

Moving a VM from one physical host to another while it continues to run, with no noticeable downtime.

Creating a snapshot of a VM before applying updates.

Restarting a VM on the same host after a failure.

Copying a VM's files to a backup storage location.

What is the primary purpose of a failover cluster?

To create isolated environments for testing applications.

To distribute network traffic across multiple servers for performance.

To increase storage capacity by combining disks from multiple servers.

To provide high availability by automatically moving workloads to another node if one fails.

How does clustering contribute to fault tolerance for compute resources?

By encrypting data on local disks to prevent unauthorized access.

By allowing multiple nodes to share the same storage and fail over if one node fails.

By increasing the processing power of individual nodes.

By providing redundant network paths between nodes.

What is the primary purpose of a virtual machine snapshot?

To increase the performance of the VM by optimizing its resources.

To provide a backup of the entire physical host, not just the VM.

To migrate the VM to a different host without downtime.

To capture the current state of a VM so it can be restored later if needed.
