The instance types provided by ApsaraDB for MySQL not only support stand-alone and active/standby, but also support MHA (Master High Availability) high availability.

Question

Options

• ATrue
• BFalse

• A
  24% (4)
• B
  76% (13)

Explanation

Option B (False) is correct because ApsaraDB for MySQL does not offer MHA (Master High Availability) as a supported instance type. The available instance types are limited to Basic (stand-alone) and High-availability (active/standby with automatic failover using Alibaba Cloud's own replication mechanism), and an Enterprise/Cluster edition in some configurations. MHA is an open-source third-party tool used to manage MySQL master failover in self-managed deployments, and it is not a native instance architecture offered by ApsaraDB for MySQL.

Option A (True) is wrong because it incorrectly assumes that ApsaraDB for MySQL adopts or exposes MHA as one of its instance type options, which it does not - Alibaba Cloud uses its own proprietary high availability solution under the hood.

Memory tip: Associate ApsaraDB for MySQL with Alibaba Cloud's own HA stack, not external open-source tools. MHA belongs to the self-managed MySQL world, not managed cloud database offerings like ApsaraDB.
