Which of the following statements is wrong about changing the specification of an RDS instance?

Show Suggested Answer Hide Answer
Suggested Answer: B

When changing the specifications of an RDS instance, service interruptions can occur during some upgrade and downgrade operations, depending on the RDS instance type and the complexity of the change. While upgrades are generally supported, certain modifications may result in brief downtime as the system reconfigures resources. This is contrary to option B. Additionally, database version downgrades are restricted, and MySQL 5.1 can indeed be upgraded directly to MySQL 5.6 in Alibaba Cloud RDS.

I think option B is wrong. Service interruption is common during upgrades.

Wait, you can't downgrade the database version? That’s surprising!

I’m pretty confident that you can upgrade the instance specifications, but I’m not clear on the implications of downgrading the database version.

I feel like I read somewhere that you can't directly upgrade from MySQL 5.1 to 5.6, so maybe D is the wrong one?

I remember practicing a question about RDS upgrades, and I think you can upgrade the instance but not downgrade the version, which makes option C sound correct.

I think option B might be the wrong statement, but I'm not entirely sure if there are specific conditions where it could be interrupted.
