Which of the following OSPF messages contains entire complete LSAs used during the
database exchange process?

A.
LSR

B.
LSAck

C.
LSU

D.
DD

E.
Hello

Explanation:
The Database Description (DD) packet lists a short LSA header but not the entire LSA. The
Link State Request (LSR) packet asks the neighbors for a copy of an LSA. The Link State
Update (LSU) holds the LSAs. LSAck simply acknowledges received LSAs, and Hello is
used for neighbor discovery and neighbor state maintenance.
