AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 66
A company has a 48 TB SAP application that runs on premises and uses an IBM Db2 database. The company needs to migrate the application to AWS. The company has strict uptime requirements for the application with maximum downtime of 24 hours each weekend. The company has established a 1 Gbps AWS Direct Connect connection but can spare bandwidth for migration only during non-business hours or weekends.
How can the company meet these requirements to migrate the application to AWS?
Answer options
- A. Use SAP Software Provisioning Manager to create an export of the data. Move this export to AWS during a weekend by using the Direct Connect connection. On AWS. import the data into the target SAP application. Perform the cutover.
- B. Set up database replication from on premises to AWS. On the day of downtime, ensure that the replication finishes. Perform cutover to AWS.
- C. Use an AWS Snowball Edge Storage Optimized device to send an initial backup to AWS. Capture incremental backups daily. When the initial backup is on AWS, perform database restore from the initial backup and keep applying incremental backups. On the day of cutover, perform the final incremental backup. Perform cutover to AWS.
- D. Use AWS Application Migration Service (CloudEndure Migration) to migrate the database to AWS. On the day of cutover, switch the application to run on AWS servers.
Correct answer: C
Explanation
Option C is correct because it allows for an initial bulk data transfer using AWS Snowball, followed by incremental updates, ensuring data is current at the time of the final cutover. Options A and B do not adequately address the need for minimal downtime and continuous data updates during the migration. Option D relies on a service that may not align with the company's strict uptime requirements and does not provide a clear plan for data transfer before the cutover.
