PAS-C01 Technology Practice Question
During an SAP migration to AWS, the migration team faces a challenge with the Transport Management System (TMS). The SAP system landscape includes development, quality assurance, and production systems running on separate EC2 instances. The TMS is configured with transport routes between these systems. After migration, transports fail with errors related to missing files on the transport directory. What should the team do to ensure the TMS works correctly?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up an Amazon EFS file system and mount it as the transport directory on all SAP instances.
The Transport Management System (TMS) requires a shared transport directory accessible by all SAP instances (DEV, QAS, PRD). Option B is correct because Amazon EFS provides a scalable NFS file system that can be mounted on multiple EC2 instances simultaneously, satisfying the shared storage requirement. Option A is incorrect because EBS volumes are block storage that can only be attached to a single instance; manual file copying is not feasible for ongoing TMS operations. Option C is incorrect because mounting an S3 bucket via S3FS introduces performance and consistency issues; S3 is object storage not designed for low-latency file sharing required by TMS. Option D is incorrect because AWS Storage Gateway with SMB file share adds unnecessary complexity; EFS with NFS is the standard and simpler solution for shared transport directories in SAP on AWS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an EBS volume for each SAP system and copy transport files manually.
Why it's wrong here
EBS volumes cannot be shared across multiple EC2 instances; manual copying of transport files is impractical and error-prone.
- ✓
Set up an Amazon EFS file system and mount it as the transport directory on all SAP instances.
Why this is correct
Amazon EFS provides a fully managed NFS file system that can be mounted on multiple EC2 instances, making it the ideal shared transport directory for TMS.
- ✗
Store the transport directory in an S3 bucket and mount it using S3FS.
Why it's wrong here
Using S3FS to mount an S3 bucket is not recommended for SAP TMS; it introduces latency and consistency issues, and S3 is object storage, not POSIX-compliant.
- ✗
Use AWS Storage Gateway with SMB file share to host the transport directory.
Why it's wrong here
AWS Storage Gateway with SMB file share is possible but not the standard solution; EFS with NFS is preferred for simplicity and performance.
