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.
A company is migrating its SAP ERP system to AWS and needs to minimize network latency between the SAP application servers and the database. Which AWS service or feature should be used to meet this requirement?
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 the application and database servers in the same placement group.
Placement groups in AWS, specifically cluster placement groups, provide low-latency network performance by ensuring that EC2 instances are placed in close physical proximity within a single Availability Zone. This minimizes network latency between SAP application servers and the database, meeting the requirement for high-throughput, low-latency communication critical for SAP ERP workloads.
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.
✗
Use AWS Global Accelerator for the application servers.
Why it's wrong here
Global Accelerator improves global user latency, not EC2-to-EC2 latency within the same region.
✓
Place the application and database servers in the same placement group.
Why this is correct
Placement groups provide low-latency, high-throughput networking between EC2 instances.
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.
✗
Set up VPC peering between the application and database VPCs.
Why it's wrong here
VPC peering connects separate VPCs but does not guarantee low-latency communication compared to same-placement group.
✗
Use an Elastic Load Balancer in front of the application servers.
Why it's wrong here
ELB distributes incoming traffic, not internal instance communication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-level services like Global Accelerator or load balancers with physical proximity optimizations, mistakenly thinking they reduce inter-instance latency when they actually add network hops or are designed for external traffic optimization.
Detailed technical explanation
How to think about this question
Cluster placement groups use a low-latency, 10 Gbps network link between instances, leveraging non-blocking, fully bisectional bandwidth within a single rack or set of racks. This is achieved through AWS's proprietary Nitro system and ENA (Elastic Network Adapter) drivers, which enable single-digit microsecond latency. In real-world SAP deployments, this is critical for reducing database round-trip times (RTT) for OLTP workloads, where even a 1 ms increase can degrade transaction throughput significantly.
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
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.
