Question

Options

• AOnly unbound EIP addresses can be released. Bound EIP addresses need to be unbound before
• BAfter the elastic public network IP is released, if it is used by other users, you can submit a work
• CAn elastic public IP can only be bound to one cloud resource, and the elastic public IP and cloud
• DOnly unbound EIPs can be bound

• A
  7% (4)
• B
  73% (40)
• C
  4% (2)
• D
  16% (9)

Explanation

Option B is the incorrect description because once an Elastic Public IP (EIP) is released into the shared IP pool and subsequently allocated to another user, it cannot be reclaimed by submitting a work order - that IP address is no longer yours, and cloud providers do not offer a retrieval mechanism for addresses reassigned to other customers.

Options A, C, and D are all accurate constraints: an EIP must be unbound from its resource before it can be released (A); an EIP maintains a strict one-to-one relationship with a cloud resource, meaning it can only be bound to a single resource at a time (C); and an EIP that is already bound to a resource cannot be bound to another resource until it is first unbound (D).

Memory tip: Think of a released EIP like a returned library book - once someone else checks it out, you cannot simply ask the librarian to take it back for you. "Release" is permanent from your perspective the moment another user acquires it.
