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 AWS CLI is configured to use a different region than where the stack was deployed.
The CLI command is querying the wrong region. The stack was created in us-east-1 but the CLI default region might be different. Option B is wrong because the stack was created successfully. Option C is wrong because outputs are returned correctly. Option D is wrong because the stack name is exactly as used.
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 AWS CLI is configured to use a different region than where the stack was deployed.
Why this is correct
Stack names are unique per region; querying the wrong region returns 'stack does not exist'.
- ✗
The stack was deleted after creation.
Why it's wrong here
The exhibit shows outputs, indicating successful creation.
- ✗
The stack name is case-sensitive and should be 'MyApp'.
Why it's wrong here
Stack names are case-sensitive but the command uses the exact name.
- ✗
The '--query' parameter is incorrectly formatted.
Why it's wrong here
The query syntax is correct.
