Design for New SolutionsmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is t3.large. This is correct because the CloudFormation template uses a condition with the Fn::If intrinsic function to evaluate the EnvType parameter, and when EnvType is set to 'prod', the condition resolves to true, selecting the instance type from the true branch—t3.large. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this tests your understanding of how CloudFormation conditions dynamically control resource properties based on parameter inputs, a common pattern for environment-specific deployments. A frequent trap is assuming the false branch (t2.micro) applies, but the condition logic explicitly checks for equality to 'prod'. Remember the memory tip: "Prod picks the premium—t3.large for production, t2.micro for everything else."

SAP-C02 Design for New Solutions Practice Question

This SAP-C02 practice question tests your understanding of design for new solutions. 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.

Exhibit

Refer to the exhibit.

Refer to the exhibit. A company uses AWS CloudFormation to deploy an EC2 instance. The template uses a condition to select the instance type based on the environment. The company deploys the stack with the parameter EnvType set to 'prod'. What will be the instance type of the created EC2 instance?

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

t3.large

The condition in the CloudFormation template evaluates to true when EnvType equals 'prod', so the EC2 instance is created with the instance type specified in the condition's true branch, which is t3.large. The template uses a condition like 'If(Equals(EnvType, 'prod'), t3.large, t2.micro)', and since the parameter is set to 'prod', the Fn::If intrinsic function returns 't3.large'.

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.

  • t3.large

    Why this is correct

    The condition IsProduction is true, so Fn::If returns t3.large.

    Related concept

    Read the scenario before looking for a memorised answer.

  • The instance type will be determined at runtime.

    Why it's wrong here

    The template explicitly sets the instance type based on the condition.

  • The instance will not be created because the condition is false.

    Why it's wrong here

    The condition is used for instance type selection, not for resource creation.

  • t2.micro

    Why it's wrong here

    t2.micro is returned only when EnvType is not prod.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse a false condition with skipping resource creation, but in this case the condition is used only to select a property value, not to conditionally create the resource itself.

Detailed technical explanation

How to think about this question

CloudFormation conditions are evaluated during stack operations using the Fn::If intrinsic function, which returns one of two values based on the condition's boolean result. The condition itself is defined in the Conditions section and can use functions like Fn::Equals, Fn::Not, or Fn::And. In this scenario, the condition likely checks if the EnvType parameter equals 'prod', and the Fn::If in the InstanceType property selects t3.large for the true branch and t2.micro for the false branch.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
