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.
