The answer is a cluster placement group within a single Availability Zone. This placement strategy is correct because it physically co-locates all SAP application and database servers in close proximity, minimizing network hops and leveraging non-blocking, high-bandwidth networking to achieve the lowest possible latency and maximum throughput for the SAP app-database communication. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that while spread or partition groups offer fault isolation, only a cluster placement group satisfies the strict low-latency requirements of SAP’s synchronous database traffic. A common trap is choosing a multi-AZ setup for high availability, but that introduces cross-AZ latency, which is unacceptable for this scenario. Memory tip: think “Cluster for Closeness” — when SAP needs the fastest path between app and database, cluster them together in one AZ.
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company is designing a new SAP environment on AWS. The SAP application servers communicate with the database over the network. The architect wants to minimize latency and maximize throughput. Which placement strategy should the architect use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Place all servers in a single Availability Zone and use a cluster placement group.
A cluster placement group is the correct choice because it provides the lowest possible latency and highest throughput by ensuring that all SAP application and database servers are placed in close physical proximity within a single Availability Zone. This placement minimizes network hops and leverages non-blocking, high-bandwidth networking, which is critical for SAP's latency-sensitive communication between application and database layers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Place all servers in a single Availability Zone and use a cluster placement group.
Why this is correct
Cluster placement group provides low latency and high throughput.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Place the application servers in one Availability Zone and the database in a different Availability Zone.
Why it's wrong here
Cross-AZ traffic adds latency compared to same AZ.
✗
Place the application servers in one VPC and the database in a different VPC connected via VPC peering.
Why it's wrong here
VPC peering adds slight latency; same VPC is better.
✗
Place the application servers in one AWS Region and the database in another Region.
Why it's wrong here
Cross-Region latency is too high for SAP database communication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume spreading resources across multiple Availability Zones improves availability, but for SAP workloads requiring minimal latency, a single-AZ cluster placement group is the correct performance optimization, even though it sacrifices AZ-level fault tolerance.
Detailed technical explanation
How to think about this question
A cluster placement group uses a low-latency, 10 Gbps or 25 Gbps network fabric within a single Availability Zone, ensuring that all instances are in the same rack or nearby racks. This is ideal for SAP HANA or any SAP database where sub-millisecond latency is required for OLTP transactions. However, cluster placement groups have a limited number of instances per group (typically 7-8 per AZ for some instance types), so architects must plan for capacity constraints when scaling.

Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

Variation 1. A company is migrating SAP ECC to AWS and needs to ensure low-latency connectivity between the SAP application and database servers. Which AWS service is most appropriate to achieve this?
easy
A.VPC peering between the application and database subnets.
✓ B.Placement groups for the application and database instances.
C.AWS Direct Connect to connect the application and database servers.
D.AWS Transit Gateway to connect the application and database subnets.
Why B: Placement groups, specifically cluster placement groups, provide low-latency, high-throughput network connectivity by placing instances in a single Availability Zone within a low-latency, 10 Gbps network. This is ideal for SAP ECC where the application and database servers require consistent, sub-millisecond latency for optimal performance.
