You wrote this snippet to request Spot Instances but get an error:

aws ec2 request-spot-instances --spot-price 0.03 --instance-count 2 --launch-specification spec.json

What is the likely cause?

BSpot price must be higher than 0.05

CMissing 'file://' prefix before spec.json

Step-by-Step Solution

Solution:

Step 1: Check file parameter syntax
The launch specification file must be referenced with 'file://' prefix.
Step 2: Validate other parameters
'--instance-count' is correct; price can be below 0.05; CLI supports Spot requests.
Final Answer:
Missing 'file://' prefix before spec.json -> Option C
Quick Check:
File paths need 'file://' prefix [OK]

Quick Trick: Use 'file://' prefix for JSON files in CLI [OK]
