Which statement describes the process ID that is used to run OSPF on a router?
A . It is globally significant and is used to represent the AS number.
B . It is locally significant and is used to identify an instance of the OSPF database.
C . It is globally significant and is used to identify OSPF stub areas.
D . It is locally significant and must be the same throughout an area.

Answer: B

Explanation:

The Process ID for OSPF on a router is only locally significant and you can use the same number on each router, or each router can have a different number-it just doesn’t matter. The numbers you can use are from 1 to 65,535. Don’t get this confused with area numbers, which can be from 0 to 4.2 billion.
