Question 1,170 of 1,733
Quick Answer
The answer is 2 subnets. This is correct because the command output explicitly lists two subnets, one in us-east-1a and one in us-east-1b, which directly satisfies the requirement for deploying an SAP system across two Availability Zones for high availability. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to read command output and apply it to the subnet count needed for an SAP HA deployment, where each Availability Zone typically requires its own subnet for the application and database layers. A common trap is overcomplicating the answer by assuming you need four subnets for separate tiers, but the question specifically asks how many subnets are available from the output, not how many are theoretically required. Remember the memory tip: for SAP HA across two AZs, count the subnets in the output, not the layers.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Network Topology
An SAP administrator wants to deploy a SAP system across two Availability Zones for high availability. The administrator runs the command shown in the exhibit. How many subnets are available for the deployment?

Correct answer & explanation
✓
2
Option B is correct because the output shows two subnets, one in us-east-1a and one in us-east-1b. Option A is wrong because there are two subnets. Option C is wrong because there are not four. Option D is wrong because there are exactly two.
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.

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.
