質問 4

Which of the following is true about Link-LSA of OSPFv3?

A. Contains both the link-local address of this interface and all IPv6 prefixes of this interface.

B. If the Prefix Option field of a prefix of the Link-LSA is 0x00, the Prefix will not be included in the IPv6 unicast calculation.

C. The Option field exists in the LSA header, not in the data area of Link-lsa.

正解: A

質問 5

Which type of prefix will the router running BGP advertise to its own IBGP neighbor (assuming the router is not configured as a route reflector)?

A. Presences existing in routing shows

B. The prefix is learned by other BGF neighbors, or the prefix is locally learned through network or route introduction.

C. The prefix is learned by other IBGP neighbors, or the prefix is learned from the EBGP neighbor, or the prefix is learned through the route introduction.

D. The prefix is learned through the EBGP neighbor, or the prefix is learned from the RR.

E. The prefix is learned through the EBGP neighbor, or the prefix is learned locally through the network or route.

正解: E

質問 10

Huawei's two switches SWA and SWB are connected through 7 Ethernet ports and configured with static link aggregation. The corresponding ports on the switch SW are Ethernet1/0/2, Ethernet1/0/3, Ethernet1/0/4. Ethernet 1/0/5, Ethernet 1/0/6, and Ethernet 1/0/7 are configured in the order of the ports. If the switch SWA and SWB supports only 6 ports per aggregation group,

A. In the case of each interface configuration consistent, Ethernet1/0/7 Unselected port

B. In the case of each interface configuration consistent, Ethernet1/0/1 Unselected port

C. In the case of each interface configuration consistent, Ethernet1/0/6 Unselected port

D. In the case of each interface configuration consistent, SWA randomly select a port in 7 ports as aggregation Unselected port
