- A
Whether the instance is EBS-optimized or has dedicated EBS bandwidth.
SAP HANA requires EBS optimization; the exhibit does not show this attribute (shown in describe-instances as 'EbsOptimized').
- B
Whether the instance is in a placement group.
Why wrong: Placement groups affect network performance but are not the primary factor for EBS optimization.
- C
The volume type and IOPS of the attached EBS volumes.
Why wrong: While important, the exhibit shows volume IDs but not type or IOPS; however, the question asks for additional information to determine if the instance is optimized, and EBS optimization is a key requirement.
- D
Whether the AMI used is SAP-certified.
Why wrong: The AMI can be customized; certification depends on instance type and configuration, not AMI ID.
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 HANA administrator is troubleshooting a performance issue on an EC2 instance (r5.8xlarge) running SAP HANA. The instance has two EBS volumes attached. Based on the exhibit, which additional information is needed to determine if the instance is optimized for SAP HANA?
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
Whether the instance is EBS-optimized or has dedicated EBS bandwidth.
Option A is correct because SAP HANA requires high and consistent network throughput for data replication and client access, and the instance must be EBS-optimized or have dedicated EBS bandwidth to ensure that EBS I/O does not contend with network I/O. Without this confirmation, the administrator cannot guarantee that the instance meets SAP's performance requirements for HANA workloads, as non-optimized instances share the same network interface for both EBS and data traffic, leading to potential bottlenecks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Whether the AMI used is SAP-certified.
Why it's wrong here
The AMI can be customized; certification depends on instance type and configuration, not AMI ID.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often focus on storage parameters like volume type and IOPS (Option C) because they are directly tied to SAP HANA's performance, but the question specifically asks about the instance's optimization, which is a network-level attribute that controls how EBS traffic is handled, not the storage configuration itself.

Command / output trap
While important, the exhibit shows volume IDs but not type or IOPS; however, the question asks for additional information to determine if the instance is optimized, and EBS optimization is a key requirement.
Detailed technical explanation
How to think about this question
EBS-optimized instances dedicate a separate virtualized network path for EBS traffic, using a dedicated NIC and a separate queue to avoid contention with data network traffic. For SAP HANA, which relies on low-latency storage and high-throughput network replication (e.g., HANA System Replication), the r5.8xlarge instance must have EBS optimization enabled by default (as it is for all current-generation instances), but the administrator must verify that the instance is launched with the 'EBS-optimized' attribute set to true, as older or misconfigured instances may lack this. In real-world scenarios, failing to confirm this can lead to unpredictable performance degradation during peak loads, especially when using large EBS volumes with provisioned IOPS.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
