PAS-C01 Design of SAP Workloads on AWS Practice Question

A company runs SAP ERP on AWS with a Microsoft SQL Server database. The system is experiencing slow batch job processing. The database server is an r5.8xlarge instance with EBS gp2 volumes. Monitoring shows high disk queue length on the data and log volumes. What change will most likely improve batch job 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

✓

Move the tempdb files to a dedicated EBS io2 volume with high IOPS.

Moving tempdb to a separate, high-performance EBS io2 volume reduces contention on the data and log volumes. Option B directly addresses the bottleneck. Option D (instance size upgrade) may help but is costly and less direct. Option A (RDS migration) is a major re-architecture, not a simple fix. Option C (instance store) is non-persistent and not suitable for tempdb in production.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Migrate the SQL Server database to Amazon RDS for SQL Server.

    Why it's wrong here

    Migration is a major change; not immediate optimization.

  • ✓

    Move the tempdb files to a dedicated EBS io2 volume with high IOPS.

    Why this is correct

    Dedicated tempdb volume reduces contention and improves I/O.

  • ✗

    Store the tempdb on an instance store volume.

    Why it's wrong here

    Instance store is ephemeral; not recommended for persistent data.

  • ✗

    Upgrade the EC2 instance to r5.12xlarge.

    Why it's wrong here

    More CPU may not resolve disk queue issues.
