The correct answer is to request a VPC limit increase from AWS Support. This is because the error "CloudFormation VPC limit exceeded" occurs when your AWS account has reached the default soft limit of five VPCs per region, and CloudFormation cannot create a new VPC until that quota is raised. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding that VPC limits are per-region soft limits that can be increased via a support ticket, rather than by modifying the template or deleting existing resources. A common trap is attempting to change the template to use an existing VPC or deleting other VPCs, but the fastest path to deploy the stack without disruption is a limit increase. Remember: for a "Handling VPC Limit Exceeded Error in CloudFormation Stack Creation," think "soft limit, support ticket"—the quota is adjustable, not a hard block.
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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 uses AWS CloudFormation to deploy a VPC with public and private subnets. The stack creation fails with the error 'The maximum number of VPCs has been reached.' The SysOps administrator needs to deploy the stack as soon as possible. What should the administrator do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Request a VPC limit increase from AWS Support.
Option C is correct because the error 'The maximum number of VPCs has been reached' indicates the AWS account has hit the default VPC limit (5 per region). Requesting a service limit increase from AWS Support is the fastest way to raise this soft limit without modifying existing infrastructure or templates, allowing the stack to deploy in the same region.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Delete unused VPCs to free up capacity.
Why it's wrong here
This is time-consuming and may disrupt other resources.
✗
Modify the CloudFormation template to use an existing VPC.
Why it's wrong here
This would require significant template changes and may not meet requirements.
✓
Request a VPC limit increase from AWS Support.
Why this is correct
Increasing the limit allows creation of additional VPCs.

✗
Deploy the stack in a different AWS region.
Why it's wrong here
The limit may also be reached in other regions, and this may not be possible due to compliance.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose to delete unused VPCs (Option A) thinking it's faster, but AWS Support limit increases are often quicker and safer than auditing and deleting resources, especially in production environments.
Detailed technical explanation
How to think about this question
AWS VPC limits are per-region soft limits (default 5 per region) that can be increased via Service Quotas or AWS Support. The CloudFormation stack creation fails at the resource creation stage when AWS attempts to provision a new VPC and the account's quota is exhausted. Requesting a limit increase typically takes minutes to hours for approval, making it the most efficient path when the stack must be deployed in the same region.

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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
