AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 251

A company runs applications on Windows and Linux Amazon EC2 instances. The instances run across multiple Availability Zones in an AWS Region. The company uses Auto Scaling groups for each application.

The company needs a durable storage solution for the instances. The solution must use SMB for Windows and must use NFS for Linux. The solution must also have sub-millisecond latencies. All instances will read and write the data.

Which combination of steps will meet these requirements? (Choose three.)

Answer options

• A. Create an Amazon Elastic File System (Amazon EFS) file system that has targets in multiple Availability Zones.
• B. Create an Amazon FSx for NetApp ONTAP Multi-AZ file system.
• C. Create a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume to use for shared storage.
• D. Update the user data for each application’s launch template to mount the file system.
• E. Perform an instance refresh on each Auto Scaling group.
• F. Update the EC2 instances for each application to mount the file system when new instances are launched.

Correct answer: B, D, E

Explanation

The correct answer is B, D, E because Amazon FSx for NetApp ONTAP provides both SMB and NFS access, making it suitable for the requirements. Updating the user data in the launch template and performing an instance refresh ensures that all instances can access the newly created file system. The other options either do not provide the required protocols or do not properly integrate with Auto Scaling.
