問題文
A team plans to place the primary and the standby of an application in two availability domains of the same region, because the latency between them is lower than between regions. What is the main limitation of this choice?
選択肢
- The limitation is that the recovery point objective becomes worse inside one region.
- A configuration inside one region is not supported at all, so the design cannot be built.
- The limitation is that plans cannot be generated automatically for members that live in the same region, so every group and every step has to be written by hand, which makes the design far more expensive to maintain than a cross-region design.
- An outage that affects the whole region takes down both sides, which is why a configuration that spans two regions is recommended for disaster recovery.
