- A
Provision Amazon EBS volumes with Provisioned IOPS (io2) for the database.
Provisioned IOPS volumes deliver consistent, low-latency performance for I/O-intensive workloads.
- B
Use an EBS-optimized instance for dedicated bandwidth to EBS.
EBS-optimized instances provide dedicated network throughput for EBS, reducing I/O bottlenecks.
- C
Configure EBS Multi-Attach to allow multiple instances to share the same volume for parallel I/O.
EBS Multi-Attach can increase aggregate I/O by allowing multiple instances to access the same volume simultaneously (if the database supports it).
- D
Use instance store volumes for the database files to reduce latency.
Why wrong: Instance store volumes are temporary and data is lost on instance stop/termination; not suitable for database persistence.
- E
Offload database backups to Amazon S3 using the Oracle Secure Backup module.
Why wrong: Offloading backups to S3 does not improve primary I/O performance; it may free some resources but is not a design change for I/O.
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An SAP system on AWS uses an Oracle database on EC2. The database is experiencing I/O bottlenecks. Which THREE design changes can improve I/O 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
Provision Amazon EBS volumes with Provisioned IOPS (io2) for the database.
Option A is correct because Amazon EBS io2 volumes provide consistent, low-latency I/O performance with a guaranteed IOPS rate, which directly addresses I/O bottlenecks for Oracle databases on EC2. By provisioning dedicated IOPS, you eliminate the variability of burstable gp2/gp3 volumes, ensuring predictable throughput for SAP workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse EBS-optimized instances (which ensure network bandwidth) with actual I/O performance improvements, or they mistakenly think Multi-Attach can parallelize I/O for a single database, when it is designed for multi-instance shared access only.
Detailed technical explanation
How to think about this question
EBS io2 volumes use a single-digit millisecond latency and deliver up to 256,000 IOPS per volume with a 99.999% durability SLA, making them ideal for Oracle redo logs and data files. Under the hood, io2 volumes leverage a Nitro-based architecture for consistent performance, and they support EBS Multi-Attach only for specific clustered configurations like Oracle RAC, not for single-instance I/O improvements. In real-world SAP deployments, misconfiguring EBS-optimized instances or using burstable volumes can lead to I/O credit exhaustion, causing sudden performance drops that io2 eliminates.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
