Question 1,684 of 1,616
PAS-C01 Technology Practice Question
An SAP system uses an NFS share from an EFS file system for transport files. Recently, the transport directory performance has degraded. Which change would most likely improve performance?
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
✓
Enable Provisioned Throughput on the EFS file system.
Using Provisioned Throughput on EFS ensures consistent performance regardless of file system size. Option A is wrong because increasing burst credits only helps temporarily. Option C is wrong because FSx for Lustre is for high-performance computing, not general purpose NFS. Option D is wrong because moving to S3 would require application changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the burst credit balance by creating more files.
Why it's wrong here
Burst credits are limited and not a permanent solution.
- ✓
Enable Provisioned Throughput on the EFS file system.
Why this is correct
Provisioned Throughput ensures consistent IOPS for NFS workloads.
- ✗
Migrate the transport directory to Amazon FSx for Lustre.
Why it's wrong here
FSx for Lustre is designed for high-performance computing, not SAP transport files.
- ✗
Use Amazon S3 with an NFS mount via AWS Storage Gateway.
Why it's wrong here
This adds complexity and may not improve performance.
