[All ACP-Cloud1 Questions]

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

AThe load on this read-only instance is significant.

BThere exists significant load on the ECS that is connected to this read-only instance.

CThe specification of this read-only instance is too low.

DThis read-only instance's master instance is performing a lot of write operations.

Show Suggested 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.
