CompTIA Server+ SK0-005 Practice Question

Your company operates a revenue-critical OLTP database on a SAN in its primary datacenter and has a secondary datacenter 25 km away connected by redundant 25 Gbps dark-fiber links with round-trip latency below 2 ms. Management has set a recovery point objective of 0 seconds and a recovery time objective of 5 minutes. Administrators want the simplest solution that meets these objectives without installing any host-level agents or clustering software. Which replication technique BEST satisfies these requirements?

  • Array-based synchronous block-level mirroring between the two SAN controllers

  • SQL Server log shipping to the secondary site at 5-minute intervals

  • Host-based asynchronous file replication using rsync every 5 minutes

  • Hourly snapshot replication to a public-cloud object store
