SK0-003 · Question #761

Which of the following is the advantage of Server to Server replication in a cluster environment over Disk to Disk?

The correct answer is D. Provides greater overall fault tolerance. Server to Server replication in a cluster environment improves fault tolerance by continuously synchronizing data between multiple servers, ensuring data availability during a server failure.

Why each option

Server to Server replication in a cluster environment improves fault tolerance by continuously synchronizing data between multiple servers, ensuring data availability during a server failure.

AReduced network traffic

Server to Server replication typically increases network traffic because data changes must be transmitted across the network between the replicating servers.

BFrequent BIOS updates are not required

BIOS updates are hardware-level maintenance tasks and are not directly influenced or reduced by the choice between Server to Server or Disk to Disk replication methods.

CBackup agent does not need to be installed

Server to Server replication is a high availability solution, not a backup solution, and therefore does not eliminate the need for backup agents or regular data backups.

DProvides greater overall fault toleranceCorrect

Server to Server replication, often implemented through technologies like Microsoft Storage Replica, provides block-level replication of volumes between servers. This means that if one server in the cluster fails, the data is already consistent and available on another server, allowing for immediate failover and significantly increasing overall fault tolerance and business continuity.
