Question 121

at the VLAN (802.1Q) The priority field in the data encapsulation is 6 bits in total.

A.True

B.false

Question 122

As shown in the figure, there is a PPP link between R1 and R2, and the direct-connected interfaces are not in the same network segment, but the direct-connected interfaces of R1 and R2 can communicate, but the Ethernet link cannot communicate with the same IP plan. The reason is that? (multiple choice)

A.The interconnected POS ports of R1 and R2 learn the 32-bit host route of each other's directly connected ports through IPCP

B.The interconnected POS ports of R1 and R2 learn the MAC address of the peer interface through LCP, and do not need to use ARP to request the MAC address

C.The data packets of the interconnected POS ports of R1 and R2 do not need to encapsulate the Ethernet header, and do not need to use ARP to request the MAC address

D.The interconnected POS ports of R1 and R2 learn the 24-bit subnet route of each other's directly connected ports through IPCP

Question 123

Which of the following descriptions about OSPFV3 packets is correct?

A.The LSR packet contains the complete LSA header information and is used to request to update the LSA

B.The Hello packet must contain the interface ID of the sending interface

C.The Option field of Hello and DD packets is extended to 24 bits

D.The LSACK message contains the LSA header information to confirm receipt of the LSU message

Question 124

The following topology diagram is available. According to this analysis, which of the following statements is correct?

A.Route entries for 10.0.2.2/32 and 10.0.0.0/16 exist in R1's IP routing table

B.Route entries for 10.0.2.2/32 and 10.0.3.3/32 exist in R1's IP routing table

C.becauseR2 has performed route aggregation, and only the route entry of 10.0.0.0/16 exists in the IP routing table of R1

D.There are both 10.0.3.3/32 and 10.0.0.0/16-bit routing entries in the IP routing table of R1

Question 125

The IPv6 link-local address can be generated through stateless automatic configuration.

A.TRUE

B.FALSE
