[All AWS Certified Solutions Architect - Professional Questions]

A manufacturing company is growing exponentially and has secured funding to improve its IT infrastructure and ecommerce presence. The company's ecommerce platform consists of:
✑ Static assets primarily comprised of product images stored in Amazon S3.
✑ Amazon DynamoDB tables that store product information, user information, and order information.
✑ Web servers containing the application's front-end behind Elastic Load Balancers.
The company wants to set up a disaster recovery site in a separate Region.
Which combination of actions should the solutions architect take to implement the new design while meeting all the requirements? (Choose three.)

A. Enable Amazon Route 53 health checks to determine if the primary site is down, and route traffic to the disaster recovery site if there is an issue.
B. Enable Amazon S3 cross-Region replication on the buckets that contain static assets.
C. Enable multi-Region targets on the Elastic Load Balancer and target Amazon EC2 instances in both Regions.
D. Enable DynamoDB global tables to achieve a multi-Region table replication.
E. Enable Amazon CloudWatch and create CloudWatch alarms that route traffic to the disaster recovery site when application latency exceeds the desired threshold.
F. Enable Amazon S3 versioning on the source and destination buckets containing static assets to ensure there is a rollback version available in the event of data corruption.

The first issue with E is that its based on latency. Second , cloud watch alarms don't just switch traffic and they need to trigger a lambda function to do that which is not mentioned Third , even if lambda was mentioned why would you use this option if its supported natively in route 53 without the need to implement this long process Remember that in the professional exam some option could be done technically but you are asked for the *Best option so in this case A is better to do this and more reliable

AB &D for me. Slightly tricky question. But R53 will cover the DR requirement. S3 CRR means there is another copy of the data in another region and Global tables ensure multiple copies of the data in case of site down.

ABD, seems right but it doesn't fully answer the question: "Which combination of actions, while meeting all the requirements?" as it's not stating anything about the application layer. However, another picks are not correct either. So I would answer ABD :D C: There's no multi-region targets in ELB. However you can load balance traffic with the IP addresses, so you could do it.

It's not clear if versioning is enabled on S3 buckets in source and destination region. Without that CRR will not work. So I will go with A,D, F. Static content will not change. So no need to sync up but in case someone deletes it or gets corrupted you can go to the previous version.

A,B,D Not F because the requirement is for a DR site.

On second thought I will go with ABD. B is correct and F is wrong because if cross region replication is enabled then versioning is enabled as well without which cross region replication is not possible.
