Question 99 of 1,746
Accelerate Workload Migration and ModernizationmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is an incorrect resource type in the launch configuration. The most likely cause of the CloudFormation Auto Scaling group creation failure is that the template mistakenly declares the launch configuration using the resource type AWS::AutoScaling::AutoScalingGroup instead of the correct AWS::AutoScaling::LaunchConfiguration. This is a classic resource type error where the logical resource for defining instance launch settings is misidentified, causing CloudFormation to reject the template because it expects a valid resource type for the launch configuration. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this tests your precise knowledge of CloudFormation resource specification and common misconfigurations; a frequent trap is confusing the Auto Scaling group resource with its supporting launch configuration or launch template. To avoid this, remember the memory tip: "The group holds the fleet, the launch config builds the car"—the Auto Scaling group (AWS::AutoScaling::AutoScalingGroup) manages scaling, while the LaunchConfiguration (AWS::AutoScaling::LaunchConfiguration) defines the instance blueprint.

SAP-C02 Practice Question: Accelerate Workload Migration and Modernization

This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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.

# CloudFormation template snippet
Resources:
  MyAutoScalingGroup:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties:
      AvailabilityZones:
        - us-east-1a
        - us-east-1b
      LaunchConfigurationName: !Ref MyLaunchConfig
      MinSize: '2'
      MaxSize: '10'
      DesiredCapacity: '2'
      TargetGroupARNs:
        - !Ref MyTargetGroup
  MyLaunchConfig:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties:
      ImageId: ami-12345678
      InstanceType: t2.micro
      SecurityGroups:
        - !Ref MySecurityGroup

A company is deploying a web application using the above CloudFormation template. The template fails to create the Auto Scaling group. What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

The LaunchConfiguration resource type is incorrect.

Option C is correct because the launch configuration uses the wrong resource type (AWS::AutoScaling::AutoScalingGroup) instead of AWS::AutoScaling::LaunchConfiguration. Option A is wrong because t2.micro is a valid instance type. Option B is wrong because the AvailabilityZones are valid. Option D is wrong because MinSize=2 is valid.

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.

  • The instance type t2.micro is not supported in us-east-1.

    Why it's wrong here

    t2.micro is available in us-east-1.

  • The MinSize value must be less than the DesiredCapacity.

    Why it's wrong here

    MinSize can be equal to DesiredCapacity.

  • The LaunchConfiguration resource type is incorrect.

    Why this is correct

    MyLaunchConfig is defined as AWS::AutoScaling::AutoScalingGroup instead of AWS::AutoScaling::LaunchConfiguration.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • The AvailabilityZones list is invalid because it uses names instead of zone IDs.

    Why it's wrong here

    Availability zone names are acceptable.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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

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.
