質問 # 41
A router receives an OSPF database description packet from a neighbor that references an LSA, which is already in the router's LSDB. The sequence number in the DBD packet is lower than the sequence number of the LSA in the LSDB.
What action does the router take?
- A. The router sends a link-state update to its neighbor.
- B. The router takes no action.
- C. The router updates the information in its LSDB with the information received from its neighbor.
- D. The router sends a link-state acknowledgement to its neighbor.
- E. The router sends a link-state request to its neighbor.
正解：A
質問 # 42
What best describes the type of packets used by OSPF routers to exchange updates on a pointto-point link?
- A. IP packets sent to an IP unicast address.
- B. UDP packets sent to an IP multicast address.
- C. IP packets sent to an IP multicast address.
- D. Ethernet frames sent to an Ethernet multicast address.
正解：C
質問 # 43
In an IP datagram, which of the following fields identifies the receiving application?
- A. The protocol field of the network layer header.
- B. The port field of the transport layer header.
- C. The protocol field of the transport layer header.

正解：B
質問 # 44
Which of the following statements regarding OSPF routing updates on a point-to-point link is true?
- A. On a point-to-point link, there is no need for a DR and BDR election. All routing updates are sent to the unicast address of the neighbor's interface.
- B. On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 224.0.0.5.
- C. On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
- D. On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
正解：B

- C. The age for newly created link state information is set to 0 for OSPF and 1200 for IS-IS
