Question 200
An enterprise architecture team faces this design requirement: A customer database needs a near-real-time cross-Region read replica and an established disaster recovery promotion procedure. Which action would resolve the problem without adding unrelated capabilities?
Explanation
Correct Answer
Aurora Global Database supports low-latency crossregional replication with explicit recovery operations. The required architecture outcome is: A customer database needs a near-real-time cross-Region read replica and an established disaster recovery promotion procedure. Validate this choice by checking that Replica lag and promotion tests meet defined RPO and RTO targets during planned and simulated events.
Incorrect Answers
Local Config assessments exist but no aggregation exposes cross-account status. The specific problem here is that a single-Region Aurora cluster lacks a suitable crossregional disaster recovery target.
No archive or retention mechanism was configured before the subscriber outage. The specific problem here is that a single-Region Aurora cluster lacks a suitable crossregional disaster recovery target.
A single-Region DynamoDB table cannot accept the required local writes after that Region fails. The specific problem here is that a single-Region Aurora cluster lacks a suitable crossregional disaster recovery target.
