Q29 — AWS DOP-C02 Ch.1
Question 29 of 100 | ← Chapter 1
A company discovers its production and disaster recovery environments are deployed in the same AWS Region. All production applications run on Amazon EC2 instances managed by AWS CloudFormation. These applications use Amazon FSx for NetApp ONTAP file storage. EC2 instances host no application data locally. The DevOps team must migrate the non-production systems to a new Region. The DevOps team has updated CloudFormation templates to accept a Region parameter. Storage replication must meet a 10-minute Recovery Point Objective (RPO).
- A. Create an Amazon S3 bucket in each Region. Configure S3 Cross-Region Replication (CRR). Create a scheduled AWS Lambda function to copy new content from FSx to the production Region’s S3 bucket.
- B. Use AWS Backup to create a backup vault and a custom backup plan with 10-minute frequency. Specify the DR Region as the destination. Assign the production Region’s EC2 instances to the backup plan.
- C. Create an AWS Lambda function to create snapshots of instance store volumes attached to EC2 instances. Configure the Lambda function to copy snapshots to the DR Region and delete prior copies. Create an Amazon EventBridge scheduled rule to invoke the Lambda function every 10 minutes.
- D. Create an Amazon FSx for NetApp ONTAP file system and configure a 5-minute SnapMirror schedule to replicate data from the production Region to the DR Region. ✓
Correct Answer: D. Create an Amazon FSx for NetApp ONTAP file system and configure a 5-minute SnapMirror schedule to replicate data from the production Region to the DR Region.
Explanation
Option D is correct because Amazon FSx for NetApp ONTAP natively supports SnapMirror for asynchronous, low-RPO cross-Region replication. A 5-minute SnapMirror schedule meets and exceeds the 10-minute RPO requirement, ensures data consistency at the storage layer, and handles incremental synchronization automatically. Options A, B, and C fail: S3 CRR cannot replicate FSx data directly; AWS Backup does not support FSx for NetApp ONTAP; and EC2 instance store snapshots are ephemeral and irrelevant since application data resides on FSx—not instance stores.
