A customer creates four broadcast domains with the following ports included for node cl-01: bcast1 - e0c bcast2 - e0d bcast3 - e0e bcast4 - e0f A customer creates a LIF and specifies a home port of cl
The correct answer is C. bcast1. A LIF's broadcast domain membership is determined by its home port; reassigning the home port to e0c places the LIF into whichever broadcast domain contains that port.
Question
A customer creates four broadcast domains with the following ports included for node cl-01:
bcast1 - e0c bcast2 - e0d bcast3 - e0e bcast4 - e0f A customer creates a LIF and specifies a home port of cl-01:e0f. After LIF creation, the administrator modifies the home port to use cl-01:e0c. Which broadcast domain is the LIF using now?
Options
- Abcast4
- Bbcast2

Why each option
A LIF's broadcast domain membership is determined by its home port; reassigning the home port to e0c places the LIF into whichever broadcast domain contains that port.
bcast4 contains port e0f, which was the original home port; once the home port is changed to e0c the LIF is no longer associated with bcast4.
bcast2 contains port e0d, which was never configured as this LIF's home port.
After the administrator changes the LIF's home port to cl-01:e0c, ONTAP reassigns the LIF to bcast1 because bcast1 is the broadcast domain that contains port e0c on node cl-01; broadcast domain membership always follows the home port assignment.
bcast3 contains port e0e, which was also never assigned as the LIF's home port.
