Question 1
IntermediateDescribe, differentiate, and apply IT industry trends, standard architectures, technologies, and cloud delivery models · Describe, contrast and differentiate compute, storage and network architectures and how to select and optimize for specific customer workloads
A lead infrastructure architect is designing a high-availability multi-site storage architecture for an enterprise financial transaction database using HPE Alletra Storage MP B10000 systems. The design requires zero Recovery Point Objective (RPO) and automatic, transparent failover across two metro data centers separated by 15 kilometers, with no human intervention needed during an array outage. Which configuration must the architect specify in the design?
Answer and explanation
Correct answer: B
Active Peer Persistence over HPE Alletra MP B10000 Remote Copy provides synchronous replication with automated, transparent failover across metro distances (RPO=0, RTO=0). It requires an external Quorum Witness to avoid split-brain scenarios and uses host proximity definitions within replication policies to ensure optimized I/O paths for multi-site stretch clusters. Periodic asynchronous replication cannot achieve RPO=0. Active-active multi-controller clustering without Remote Copy cannot span metro data centers 15 km apart.
