AWS - ECS and Fargate

A"cpu": 512, "memory": 1024

B"cpu": "512", "memory": "1024"

C"cpu": "0.5", "memory": "1GB"

D"cpu": "512MB", "memory": "1GB"

Step-by-Step Solution

Solution:

Step 1: Check Fargate task definition format
Fargate expects CPU and memory as strings representing CPU units and MiB memory, e.g., "512" and "1024".
Step 2: Evaluate options
"cpu": "512", "memory": "1024" uses strings with numeric values, which is correct. Using numbers instead of strings is incorrect. Decimal values for CPU or units like GB/MB are invalid.
Final Answer:
"cpu": "512", "memory": "1024" -> Option B
Quick Check:
CPU and memory as strings = B [OK]

Quick Trick: CPU and memory must be strings in task definition [OK]
