The answer is to use the default VPC network within the same VPC spanning multiple Availability Zones. This is correct because AWS Availability Zones are connected through a redundant, high-bandwidth, low-latency network that provides single-digit millisecond latency, making it the ideal choice for SAP HANA multi-AZ network latency minimal requirements without any additional services. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this tests your understanding that the native VPC network is already optimized for inter-AZ traffic, and the common trap is overcomplicating the solution by selecting VPC Peering, Direct Connect, or Transit Gateway—all of which are unnecessary for connecting instances within a single VPC. Remember the memory tip: “Same VPC, no extra fee—AZs are already low-latency.”
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 planning to migrate their SAP system to AWS. They need to ensure that the SAP application servers and database servers are in the same AWS Region but in different Availability Zones for high availability. The network latency between Availability Zones must be minimal. Which AWS service should be used to connect the instances?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the default VPC network within the same VPC spanning multiple Availability Zones
Option A is correct because AWS uses a redundant, high-bandwidth, low-latency network between Availability Zones. Option B is wrong because VPC Peering is used for connecting different VPCs. Option C is wrong because Direct Connect is for on-premises connections. Option D is wrong because Transit Gateway is for hub-and-spoke connectivity, not needed for within a 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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set up VPC Peering between the Availability Zones
Why it's wrong here
VPC Peering is not needed within a single VPC.
✗
Establish an AWS Direct Connect connection
Why it's wrong here
Direct Connect is for on-premises connectivity.
✓
Use the default VPC network within the same VPC spanning multiple Availability Zones
Why this is correct
Instances in the same VPC across AZs communicate over AWS's low-latency network.
Transit Gateway is for multiple VPCs, not needed within one VPC.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
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
How to think about this question
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.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
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
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.
What to study next
Got this wrong? Here's your next step.
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.
