Alibaba ACP-Cloud1 Exam - Topic 6 Question 96 Discussion

Actual exam question for Alibaba's ACP-Cloud1 exam

Question #: 96
Topic #: 6

[All ACP-Cloud1 Questions]

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

AThe specification of an RDS instance can be upgraded as needed

BThe service will not be interrupted during upgrade/downgrade

CThe database version cannot be downgraded

DMySQL 5.1 can be directly upgraded to MySQL 5.6

Show Suggested 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’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.
