Step-by-Step Solution
Solution:
Step 1: Identify how to set AWS region in PowerShell
The cmdlet to set default region is Set-DefaultAWSRegion with -Region parameter.Step 2: Retrieve EC2 instances after setting region
After setting region, Get-EC2Instance fetches instances in that region. Set-DefaultAWSRegion -Region us-east-1; Get-EC2Instance correctly chains these commands.Step 3: Evaluate other options
Get-EC2Instance -RegionName us-east-1 uses invalid parameter '-RegionName'; Set-AWSRegion us-east-1; Get-EC2Instance uses a non-existent cmdlet; Get-EC2Instance | Where-Object { $_.Region -eq 'us-east-1' } filters instances locally but region info is not a direct property.Final Answer:
Set-DefaultAWSRegion -Region us-east-1; Get-EC2Instance -> Option AQuick Check:
Set region first, then get instances [OK]
Quick Trick: Set region with Set-DefaultAWSRegion before commands [OK]
Common Mistakes:
- Using wrong cmdlet to set region
- Passing -Region directly to Get-EC2Instance
- Filtering region locally without setting it
