The answer is to set up an Amazon EFS file system and mount it as the transport directory on all SAP instances. This is correct because SAP TMS requires a shared, network-accessible transport directory where all systems in the landscape can read and write transport files simultaneously; Amazon EFS provides a fully managed NFS file system that can be mounted across multiple EC2 instances in different Availability Zones, exactly replicating the on-premises shared file system behavior. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that TMS is fundamentally a shared-storage dependency, not a database or application-layer issue—a common trap is confusing EBS (block storage, single-instance) or S3 (object storage, no NFS protocol) with the POSIX-compliant shared file system that TMS demands. Remember the memory tip: TMS needs a “team” file system—EFS is the only AWS storage service that lets all SAP instances “eat from the same plate” via NFS.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 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.
Option D is correct because TMS relies on a shared transport directory; using EFS with NFS provides a shared file system accessible by all instances. Option A is wrong because S3 is object storage and not compatible as a transport directory. Option B is wrong because EBS volumes are block storage and cannot be shared across multiple instances. Option C is wrong because SMB on AWS is not a standard solution for TMS.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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
Manual copying is error-prone and not scalable.
✓
Set up an Amazon EFS file system and mount it as the transport directory on all SAP instances.
Why this is correct
EFS provides a shared NFS file system suitable for TMS.
Related concept
Static NAT maps one inside address to one outside address.
✗
Store the transport directory in an S3 bucket and mount it using S3FS.
Why it's wrong here
S3FS is not officially supported for TMS and may cause issues.
✗
Use AWS Storage Gateway with SMB file share to host the transport directory.
Why it's wrong here
SMB is not the standard for TMS; NFS is required.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
