The answer is to relaunch the deployment using a different Availability Zone in the same Region. This resolves the issue because AWS Launch Wizard allows you to specify multiple Availability Zones during the configuration phase, and if the selected instance type is not available in one AZ, you can simply choose another AZ within the same Region where that instance type is supported. Launch Wizard automatically validates resource availability against your chosen instance types, so manually modifying CloudFormation templates or re-architecting the deployment is unnecessary. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of Launch Wizard’s built-in flexibility and how to handle common provisioning failures without overcomplicating the solution. A common trap is assuming you must change the instance type or use a different Region, but the correct approach is to leverage the AZ selection feature. Memory tip: When an instance type is missing from an AZ, think “AZ shuffle, not instance swap.”
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 an SAP ERP system to AWS. They plan to use AWS Launch Wizard to deploy the SAP landscape. After running Launch Wizard, the deployment fails with an error indicating that the instance type is not available in the selected Availability Zone. What should the company do to resolve this issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Relaunch the deployment using a different Availability Zone in the same Region.
Launch Wizard allows specifying multiple Availability Zones. By selecting a different AZ where the instance type is available, the deployment can proceed. Modifying the template manually or using CloudFormation directly is not necessary as Launch Wizard provides this option.
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.
✓
Relaunch the deployment using a different Availability Zone in the same Region.
Why this is correct
Launch Wizard allows selecting multiple AZs; choose one where the instance type is available.
Create a new VPC with different subnets and rerun Launch Wizard.
Why it's wrong here
Unnecessary; can specify a different AZ in existing VPC.
✗
Modify the AWS CloudFormation template generated by Launch Wizard to specify a different instance type.
Why it's wrong here
Changing instance type may affect performance; better to choose a different AZ.
✗
Request a limit increase for the instance type from AWS Support.
Why it's wrong here
Not a capacity issue; the instance type is simply not offered in that AZ.
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.
