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.
