QuestionQ17

Solution Design

A customer has a business-critical application that must stay available if the primary site fails. The secondary site is connected by low-latency links, and the customer requires a zero RPO while preserving application availability during site-level failures, planned maintenance, or unexpected disruptions at the primary location.

Which data-protection recommendation is appropriate?

  • A Asynchronous replication
  • B Synchronous replication
  • C Metro replication
Explanation

Metro replication uses synchronous, active-active replication between low-latency sites to provide zero RPO and continuous availability through site-level failures or maintenance events.
