   A company runs a critical application on a VM. The VM is replicated to a secondary host using asynchronous replication. The primary host fails. The administrator promotes the replica on the secondary host. Which compute-based fault tolerance technique is being used?

   • ACheckpointing
   • BLoad balancing
   • CLive migration
   • DVM replication

   How does load balancing help prevent single points of failure?

   • ABy using redundant power supplies in each compute node.
   • BBy distributing traffic so that no single node is critical to the overall service.
   • CBy automatically restarting failed applications on the same node.
   • DBy storing data on multiple disks using RAID.

   A financial trading application runs on a single server. The application uses checkpointing to save its state every 5 minutes. The server experiences a power failure. After the server is restored, the application restarts from the last checkpoint. Which compute-based fault tolerance technique is demonstrated?

   • AApplication-level fault tolerance
   • BLive migration
   • CHardware redundancy
   • DLoad balancing

   How does transaction logging help ensure compute continuity?

   • ABy providing redundant power to the compute system.
   • BBy encrypting transaction data to ensure confidentiality.
   • CBy distributing transactions across multiple servers.
   • DBy recording each transaction so that the system can replay or undo them after a failure.

   How does RAID 5 provide fault tolerance for compute systems?

   • ABy combining mirroring and striping to protect against multiple disk failures.
   • BBy distributing data and parity information across all disks, allowing recovery if one disk fails.
   • CBy using a dedicated parity disk to store all redundancy information.
   • DBy duplicating every block of data on a separate disk.
