Amazon SAA-C03 Exam - Topic 2 Question 65 Discussion

Actual exam question for Amazon's SAA-C03 exam

Question #: 65
Topic #: 2

A company runs its critical storage application in the AWS Cloud. The application uses Amazon S3 in two AWS Regions. The company wants the application to send remote user data to the nearest S3 bucket with no public network congestion. The company also wants the application to fail over with the least amount of management of Amazon S3.

Which solution will meet these requirements?

AImplement an active-active design between the two Regions. Configure the application to use the regional S3 endpoints closest to the user.

BUse an active-passive configuration with S3 Multi-Region Access Points. Create a global endpoint for each of the Regions.

CSend user data to the regional S3 endpoints closest to the user. Configure an S3 cross-account replication rule to keep the S3 buckets synchronized.

DSet up Amazon S3 to use Multi-Region Access Points in an active-active configuration with a single global endpoint. Configure S3 Cross-Region Replication.

Show Suggested Answer

Suggested Answer: D

AWS S3 Multi-Region Access Points enable customers to use a single global endpoint for S3 bucket access across multiple AWS Regions, providing automatic routing to the nearest Region. This reduces public network congestion by directing user data to the closest S3 bucket and supports high availability with active-active configuration.

Cross-Region Replication ensures data is replicated between buckets in different Regions, meeting the failover and resilience requirements with minimal management overhead.

Option D aligns best with AWS's recommended approach to resilient, low-latency, and simplified multi-Region S3 access.

Option A lacks the global endpoint and automatic failover. Option B incorrectly describes Multi-Region Access Points configuration and suggests global endpoints per Region, which is contradictory. Option C's cross-account replication adds complexity and does not provide a single global endpoint.

D is interesting. A single global endpoint is appealing.

C sounds good too, but cross-account replication seems complex.

Not sure about D, seems complicated for just failover.

Wait, can you really do active-active with S3? Seems risky.

Haha, I bet the correct answer is the one that involves the most AWS services. That's how they get you!

Option A is the most complex, but it might be the most reliable. Gotta love that active-active design.

D is the way to go! Multi-Region Access Points and Cross-Region Replication, can't get any easier than that.

C looks good to me. Closest regional endpoints and cross-account replication to keep things in sync.

I'm leaning towards option A. Implementing an active-active design between the two Regions and configuring the app to use the closest endpoints sounds like the simplest way to meet the requirements without a lot of extra setup.

Option D seems like the most comprehensive solution - using Multi-Region Access Points in an active-active setup with Cross-Region Replication. That would give them the failover and load balancing they need across Regions.

I'm a bit confused by the different options here. Can the application really use the regional S3 endpoints closest to the user, as suggested in option C? Wouldn't that require some additional logic in the application?

I think option B looks promising - using S3 Multi-Region Access Points to create a global endpoint for each Region seems like it would provide the failover capabilities they're looking for with minimal management.
