How to Ensure Low-Latency Connectivity Between SAP Instances Across Availability Zones

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. A key principle to apply: vPC Network. 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?

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

✓

Placement Group (cluster)

None of the provided options correctly address the requirement. Instances in the same VPC across different Availability Zones automatically communicate over the low-latency AWS backbone network. No special feature like a Placement Group, Network ACL, Internet Gateway, or VPC Peering is needed to achieve low-latency connectivity between instances distributed across AZs. The correct answer would be to use the default VPC network.

Key principle: VPC Network

Answer analysis

Option-by-option breakdown

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 a stateless firewall that controls traffic at the subnet level; it does not affect network latency or connectivity between instances.

  • ✓

    Placement Group (cluster)

    Why this is correct

    Placement Group (cluster) places instances in a single Availability Zone for low latency; it does not support distribution across multiple AZs.

  • ✗

    Internet Gateway

    Why it's wrong here

    Internet Gateway enables internet access for instances; it does not provide low-latency connectivity between internal instances.

  • ✗

    VPC Peering

    Why it's wrong here

    VPC Peering connects two different VPCs; it is not needed for instances within the same VPC and can introduce additional latency.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap is mistaking a cluster placement group (single-AZ) as the solution for multi-AZ setups, when in fact the default VPC already provides low-latency connectivity across AZs.

Detailed technical explanation

How to think about this question

A cluster placement group packs instances close together inside a single Availability Zone, achieving single-digit millisecond latency and up to 10 Gbps of network throughput for TCP/IP traffic. For SAP NetWeaver, this is essential for the enqueue replication server (ERS) and application server instances to maintain synchronous replication with minimal delay, as even a few milliseconds of added latency can cause SAP lock timeouts or performance degradation. Under the hood, AWS uses a fully non-blocking, low-latency network fabric within the placement group, but note that cluster placement groups cannot span multiple Availability Zones, so for cross-AZ high availability, you would need a spread or partition placement group instead.

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.

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.
