The exhibit shows a CloudFormation template snippet for deploying SAP ASCS and ERS instances. Both instances are launched in the same subnet. What is the main architectural issue with this deployment?

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

Both instances are in the same Availability Zone, which defeats the purpose of high availability

For high availability, ASCS and ERS should be in different Availability Zones to avoid a single point of failure. Option B is wrong because the instance type is acceptable for a test environment. Option C is wrong because the AMI is not specified, but that is not the main issue. Option D is wrong because there is no security group defined, but that is a security issue, not an architectural HA issue.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Both instances are in the same Availability Zone, which defeats the purpose of high availability

    Why this is correct

    HA requires instances in different AZs.

  • The AMI ID is not specified correctly

    Why it's wrong here

    The AMI ID is a placeholder but not the main issue.

  • The instance type m5.large is too small for SAP

    Why it's wrong here

    m5.large may be sufficient for a small environment.

  • No security group is defined, exposing the instances to the internet

    Why it's wrong here

    Security groups are important but not the main architectural HA issue.
