AWS - EC2 Fundamentals

AIt is automatically released back to AWS

BIt remains allocated to your account but is not associated with any instance

CIt stays associated with the detached network interface

DIt causes the instance to lose all network connectivity

Step-by-Step Solution

Solution:

Step 1: Understand Elastic IP behavior on network interface detach
Detaching the interface removes association; Elastic IP remains allocated but unassociated.
Step 2: Check other options
Elastic IP is not released automatically; it cannot stay associated with detached interface; instance connectivity depends on interface attachment.
Final Answer:
It remains allocated to your account but is not associated with any instance -> Option B
Quick Check:
Elastic IP stays allocated but unassociated after detach [OK]

Quick Trick: Detached interface frees Elastic IP but keeps it allocated [OK]

Common Mistakes:

Assuming Elastic IP is released automatically
Thinking Elastic IP stays linked to detached interface
Confusing instance connectivity with Elastic IP state
