LAST WEEK'S ANSWER:
Answer: d
Topic Domain: 4a
Issues:
What is the order of preference for OSPF routes? How can this be
overridden?
Solutions:
RFC 2328 states that the order of preference for OSPF routes is
intra-area, inter-area, external type 1, and then external type 2. While
this cannot be overridden in a single OSPF process, keep in mind that a
comparison does occur if the router is running more than one OSPF
process.
