PAS-C01 Design of SAP Workloads on AWS Practice Question
Network Topology
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?
⚠ Common exam trap
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.
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Whether the instance is EBS-optimized or has dedicated EBS bandwidth.
Why this is correct
SAP HANA requires EBS optimization; the exhibit does not show this attribute (shown in describe-instances as 'EbsOptimized').
- ✗
Whether the instance is in a placement group.
Why it's wrong here
Placement groups affect network performance but are not the primary factor for EBS optimization.
- ✗
The volume type and IOPS of the attached EBS volumes.
Why it's wrong here
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.
- ✗
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.
