video clearly states that we can't DeleteTaskLogs if instance is in "storage-full" status. Has to be in "Available" status.

C+E We need to provide more storage, not bigger instances. Also, deleting the logs will help

While C is a good action to prevent full storage you simply can't delete logs when you've already recieved the status of full stroage. So C is out. "If the replication DB instance is in a storage-full status, you can't delete logs. You must increase the allocated storage size, or delete the replication task. To increase the storage size of a replication DB instance:" It's A and E: Just check: https://repost.aws/knowledge-center/dms-replication-instance-storage-full

in the link you provided it is mentionned : "If the replication DB instance is in a storage-full status, you can't delete logs. You must increase the allocated storage size, or delete the replication task. " and they specifically say you should Increase the storage size of the replication DB instance in that case. Read carefully so you don't mislead people

In the first link you provided, it says that "If the replication DB instance is in a storage-full status, you can't delete logs. You must increase the allocated storage size, or delete the replication task". This statement makes C not possible because the replication instance entered storage-full status.

Thanks Windy. I now feel A,E is the right answer.

Not really. Once you provide more storage (coming from E), you can also delete some logs (this is C). So C+E is the correct answer. The instance size will add CPU and RAM, not storage.

But this quotation asks which option works and not a combination of options. So A and E is right because they basically do the same.

I changed my mind. As MultiAZ says, changing instance type by itself does nothing with the problem. Modifying MemoryLimitTotal and MemoryKeepTime values is also needed to avoid swapping. So C and E are more feasible. But the question actually looks for a help to solve, we don't have to resolve directly. The wording is too vague.

Selected Answer: AE

A,E is answer A. Change the size of the replication instance to a larger instance type supported. If the replication instance has reached the storage full status, it indicates that the size of the replication instance may be insufficient for the storage capacity. By changing the instance size to a larger supported type, you can increase the storage capacity. E. Increase the amount of storage allocated to the replication instance using the modify-replication-instance API. If the replication instance has reached the storage full status, it suggests that the allocated storage for the replication instance might be insufficient. By using the modify-replication-instance API, you can increase the amount of storage to address the issue. Therefore, the options that would be helpful to resolve this issue are A and E.
