SAP-C02 Design for New Solutions Practice Question
Network Topology
A Solutions Architect runs the AWS CLI command shown in the exhibit. Which statement accurately describes the output?
⚠ Common exam trap
It's easy for candidates to assume `--query` filters the instances themselves (like a WHERE clause in SQL), but it only shapes the output fields—it does not reduce the set of instances returned, so without an explicit `--filters` parameter, all instances are listed.
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 command lists all instances regardless of state.
The AWS CLI command `aws ec2 describe-instances` without any filter returns all EC2 instances in the current region, regardless of their state (running, stopped, terminated, etc.). The `--query` parameter is used correctly to extract specific fields from the JSON output, but it does not filter instances by state. Therefore, the output includes every instance, and option A is correct.
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 command lists all instances regardless of state.
Why this is correct
The command returns all instances with their state.
- ✗
The command lists instances in JSON format.
Why it's wrong here
The --output table specifies table format, not JSON.
- ✗
The command lists only running instances.
Why it's wrong here
The query does not filter by state; it returns all instances.
- ✗
The command fails because --query is used incorrectly.
Why it's wrong here
