Alibaba Exam ACP-Cloud1 Topic 8 Question 80 Discussion

Actual exam question for Alibaba's ACP-Cloud1 exam
Question #: 80
Topic #: 8
[All ACP-Cloud1 Questions]

Which of the following is not a potential cause of latency on an RDS read-only instance?

Show Suggested Answer Hide Answer
Suggested Answer: B

Latency on an RDS read-only instance can be caused by high loads on the instance itself, inadequate instance specifications, or excessive write operations on the master instance, as these factors directly impact replication delay and resource contention. However, a high load on the ECS instance connected to the RDS read-only instance would not inherently cause latency on the RDS instance, as the ECS and RDS operate independently in terms of processing.

I think the answer is C because if the specification is too low, it could cause latency issues regardless of other factors.

I'm stumped on this one. Maybe I should have read the RDS documentation more closely...

Ha! This question is a real 'page-turner'! I'm going to guess A. Significant load on the read-only instance itself seems like the most obvious cause of latency.

C could also be a factor. If the specification of the read-only instance is too low, it might struggle to keep up.

I agree with you, A seems like the most likely cause of latency on the read-only instance.

I'm going with D. If the master instance is doing a lot of writes, that could slow things down.

I think it's B. The load on the ECS could definitely be causing latency.

But if the master instance is doing a lot of writes, wouldn't that affect the read-only instance's latency?

This is a tricky one, but I'm going to say C. If the instance specs are too low, that could definitely lead to latency.

I'm not sure, but I think it could also be D. The master instance performing a lot of write operations might also cause latency.
