PAS-C01 Operations and Maintenance Practice Question

Exhibit

Refer to the exhibit.

AWS CloudFormation template snippet:
```yaml
Resources:
  SAPAppServer:
    Type: AWS::EC2::Instance
    Properties:
      InstanceType: !Ref InstanceType
      ImageId: !Ref LatestAmiId
      SecurityGroupIds:
        - !Ref SecurityGroup
      UserData:
        Fn::Base64: !Sub |
          #!/bin/bash
          /opt/sap/install.sh
```

Refer to the exhibit. An operations team uses this CloudFormation template to launch SAP application servers. After deployment, the application server fails to join the SAP system. The team verified that the security group allows outbound traffic to the SAP system. What is the MOST likely cause?

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 `LatestAmiId` parameter is not defined in the template.

The template uses `!Ref LatestAmiId` which does not exist as a parameter; it should be a parameter or a mapping. Option A is wrong because the instance type is parameterized. Option B is wrong because the security group is referenced correctly. Option C is wrong because the user data script is base64 encoded correctly.

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 is not specified correctly.

    Why it's wrong here

    InstanceType is a parameter reference, which is valid.

  • The security group ID is not properly referenced.

    Why it's wrong here

    SecurityGroupIds uses !Ref SecurityGroup, which is correct.

  • The user data script is not base64 encoded correctly.

    Why it's wrong here

    Fn::Base64 is used correctly.

  • The `LatestAmiId` parameter is not defined in the template.

    Why this is correct

    !Ref LatestAmiId requires a parameter or mapping that is not defined.
