For designing a disaster recovery strategy in ECS, which elements are critical to ensure business continuity in case of a major outage?

Question

Options

• AGeographic replication of data
• BRegular, incremental backups only
• CA detailed and regularly updated recovery plan
• DTesting the recovery plan bi-annually

• A
  82% (40)
• B
  18% (9)

Explanation

Geographic replication (A), a detailed recovery plan (C), and bi-annual testing (D) form a complete disaster recovery triad: you need data available elsewhere, a documented process to restore operations, and proof that the process actually works under realistic conditions. Without geographic replication, a regional outage destroys your failover; without a current, detailed plan, recovery becomes chaotic and slow; without periodic testing, the plan may be outdated or unexecutable when it matters most.

Why B is wrong: "Regular, incremental backups only" is insufficient on its own - incremental backups without a tested recovery plan or geographic distribution mean you have data but no reliable path to restore it quickly during a major outage. Backups are a component of DR, not a strategy.

Memory tip: Think of the RTP triangle - Replicate (A: geo-replication keeps data alive), Plan (C: documented steps guide recovery), Prove (D: testing validates the plan). Disaster recovery fails when any side of this triangle is missing - and "backups only" belongs inside the triangle, not as a replacement for it.
