AWS - ECS and Fargate

Why does AWS Fargate require the use of the awsvpc networking mode instead of bridge or host modes?

ABecause bridge mode is more secure than awsvpc

BBecause Fargate assigns each task its own elastic network interface for isolation

CBecause host mode allows multiple tasks to share the same IP address

DBecause awsvpc mode disables all networking for tasks

Step-by-Step Solution

Solution:

Step 1: Understand Fargate networking design
Fargate assigns each task its own network interface (ENI) for security and isolation.
Step 2: Explain why awsvpc is required
awsvpc mode enables this per-task ENI assignment, unlike bridge or host modes.
Final Answer:
Because Fargate assigns each task its own elastic network interface for isolation -> Option B
Quick Check:
awsvpc = per-task ENI for isolation [OK]

Quick Trick: awsvpc gives each task its own network interface [OK]
