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 running SAP NetWeaver on AWS. The SAP application server instances need to be distributed across multiple Availability Zones for high availability. Which AWS feature should be used to ensure low-latency connectivity between these instances?
Network ACL
Why wrong: Network ACL is for security filtering.
Placement Group (cluster)
Cluster placement group provides low-latency network.
Internet Gateway
Why wrong: Internet Gateway is for internet connectivity.
VPC Peering
Why wrong: VPC Peering connects different VPCs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Placement Group (cluster)
Option C is correct because placing EC2 instances in the same placement group (cluster placement group) ensures low-latency network connectivity between them, which is beneficial for SAP application servers. Option A is incorrect because an Internet Gateway is for internet access, not internal connectivity. Option B is incorrect because a Network ACL controls traffic at the subnet level, not connectivity. Option D is incorrect because VPC Peering connects different VPCs, not within the same VPC.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Network ACL
Why it's wrong here
Network ACL is for security filtering.
Placement Group (cluster)
Why this is correct
Cluster placement group provides low-latency network.

Internet Gateway
Why it's wrong here
Internet Gateway is for internet connectivity.
VPC Peering
Why it's wrong here
VPC Peering connects different VPCs.
Common exam traps
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
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.
What to study next
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related PAS-C01 subnetting questions on CIDR, address ranges, and subnet selection.
