Question 101

As shown in the figure, private network routing information is exchanged between PE1 and PE2 and their respective CEs through SPF, and the same Domain ID is declared on both PE1 and PE2. When importing routes from BGP to OSPF on PE2, which of the following types of LSAs may be delivered to CE2?

A.Type1 LSA

B.Type5 LSA

C.Type3 LSA

D.Type7 LSA

Question 102

Which of the following descriptions is wrong about the OSPFv3 protocol?

A.OSP the Fv3 packet header will contain the Interface ID field

B.Can support running multiple instances on a single link

C.In the case of sharing a router, each OSPFv3 process runs independently

D.Multiple instances can run in the same OSPFv3 process under the same interface

Question 103

You want to set the DSCP value for VoIP traffic in the HW network device to EF. According to the Differentiated Services Model RFC, the traffic marking EF should be set to:

A.DSCP set to decimal 36

B.IP ToS is set to 0xEF

C.IP Experimental EEN

D.DSCP set to decimal 5

E.bitstream 101110

Question 104

OSPFv2 is running over IPv4 Network IGP: OSPFv3 is running over IPv6 Network IGP: OSP the packet types of Fv3 and OSPFv2 are the same, incl. He11o message, DD message, LSR message, LSU message and LSAck packets. Which of the following statements is true about 0SPFv3 packets?

A.OSPFv3 ofHello The packet carries the IPv4 address of the router interface6 Address prefix list

B.OSPFv3 uses the link-local address as the source address of the sent packet, and the packet can be forwarded outside the range of the originating link

C.OSPFv3 Use IPv46 multicast addressFF02: :5 andFF02: :6 send OSPFv3 message

D.OSPFv3 uses the authentication field in the packet header to complete packet authentication

Question 105

The router connects two EBGP neighbors through two parallel serial cables, what method would you use to achieve this through the two parallel serial cablesBidirectional load sharing between two connected EBGP neighbors?

A.To configure the EBGP neighbor relationship with the loopback interface as the update source, the IGP in each AS needs to introduce two equal-cost paths to the EBGP neighbor loopback interface address; and the command "ebgp-max- hop" and "next-hop-local*

B.To configure the EBGP neighbor relationship with the loopback interface as the update source, the IGP in each AS must have two equal-cost paths to the EBGP neighbor loopback interface address; and the command "next-hop-local"

C.Use the command "ebgp on both ends"-load-balance"

D.Without any method, BGP will automatically realize the load balancing of traffic among different autonomous systems on the available links

E.Using the Loopback interface Establish EBGP neighbor relationship and configure EBGP Multi-hop, configure the loopback interface as the update source, and then use IGP to achieve equal-cost path load sharing between loopback addresses
