Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 439 discussion

I do not know why AWS writes its questions so badly. The question asks for a conjuntion answer and then they give us TOTALLY different answers that do not work together. For me, it's B without any doubts since AWS DMS allows us to migrate while reducing the interrumption on the source to be migrated and A could be an option as well but it obviously allows us to move certain amount of data until a certain point of time.

The only correct answer is B, Selecting A is to meet the question. A is not right because it will lose a certain period of data.

A is unnecessary

The question says to choose two alternatives - but it doesn't say that they must work in conjunction. I.e., separate answers that stand on their own. B is best, but A works too. Thus A+B.

A and B both are valid options.

This question should have a single answer. A and C are both using a kind of back/restore strategy, and they cannot capture the changes happens during the restore stage. D is using Application Migration Service, which is not suitable for DB migration. Only B can do this job.

This really should be a single answer, or it should say which solutions would meet this requirement. But yes A and B are both possible.

I guess that the right answer - A \ B A - Snapshots can be easily shared cross AWS accounts B - With AWS DMS - you can sync databases C - Out because - as I understood - you can't just SHARE AWS Backup with another AWS Account, you need to setup cross account AWS backup to store backups in both accounts D - Out because AWS Application migration service - can't migrate RDS databases

Answer AB: A is unnecessary, we really only need B. It works either way. https://aws.amazon.com/blogs/database/cross-account-amazon-aurora-postgresql-and-amazon-rds-for-postgresql-migration-with-reduced-downtime-using-aws-dms/

have to us DMS or snapshot for DB migration

correct answer is A and B
