AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 109
A company is running its on-premises SAP ERP Central Component (SAP ECC) production system on an Oracle database. The company needs to migrate the system to AWS and change the database to SAP HANA on AWS.
The system must be highly available. The company also needs a failover system to be available in a different AWS Region to support disaster recovery (DR). The DR solution must meet an RTO of 4 hours and an RPO of 30 minutes. The sizing estimate for the SAP HANA database on AWS is 4 TB.
Which combination of steps should the company take to meet these requirements? (Choose two.)
Answer options
- A. Deploy the production system and the DR system in two Availability Zones in the same Region.
- B. Deploy the production system across two Availability Zones in one Region. Deploy the DR system in a third Availability Zone in the same Region.
- C. Deploy the production system across two Availability Zones in the primary Region. Deploy the DR system in a single Availability Zone in another Region.
- D. Create an Amazon Elastic File System (Amazon EFS) file system in the primary Region for the SAP global file system. Deploy a second EFS file system in the DR Region. Configure EFS replication between the file systems.
- E. Set up Amazon Elastic Block Store (Amazon EBS) to store the shared file system data. Configure AWS Backup for DR.
Correct answer: C, D
Explanation
The correct answers are C and D. Option C ensures that the production system is resilient by being in two Availability Zones, while the DR system is in a different AWS Region, fulfilling the RTO and RPO requirements. Option D provides a robust file system solution with EFS replication that supports data availability across regions, which is essential for disaster recovery. Options A and B do not provide adequate regional separation for DR, while option E lacks the specific replication strategy needed for the requirements.
