PAS-C01 Operations and Maintenance Practice Question
A company runs SAP on AWS and uses a shared file system via Amazon EFS for transport files. Recently, the SAP system experienced slowness when importing transports. The CloudWatch metrics show high BurstCreditBalance for the EFS file system. What action should be taken to 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 Max I/O performance mode on the EFS file system.
When BurstCreditBalance is high, it indicates that the file system is not using its burst credits, meaning it is operating at baseline throughput. To improve performance, enable Max I/O performance mode on the EFS file system, which provides higher throughput and IOPS. Option B is incorrect because changing to General Purpose mode does not increase throughput; it may even reduce performance. Option C is incorrect because encryption does not affect throughput. Option D is incorrect because BurstCreditBalance cannot be purchased; it is automatically accrued and consumed.
