NO.80 Network administrator A wants to check the neighbor status of BGP router R2. R2’s BGP neighbor status information is shown in the figure. Please help network administrator A to obtain the following information: The AS where R2 is located is AS (). (Note: Only write numbers, do not add punctuation or spaces)

NO.81 A campus has deployed IPv6 for service testing. In the early stage of deployment, engineers wanted to achieve network interoperability through IPv6 static routes. When creating an IPv6 static route. You can specify both the outbound interface and the next hop, or only the outbound interface or only the next hop.

True

False

NO.84 According to this picture, what can we judge? (Multiple choice)

The device type of R1 is definitely not Leve1-1

R1 has 6 IS-IS IPv6 routes

R1 does not have IS-IS IPv6 routing

IS-IS IPv6 must be enabled on GigabitEthernet0D/1 of R1

NO.85 An engineer uses two routers to test IPv6 services, and simulates the headquarters and branches by running BGP4+ of interconnection. As shown in the figure, an engineer captures packets to view the update packets sent by R1. About this message Description of information, which of the following statements is correct

The next hop address of the route described in this packet is:2001:db8::2345:l.:l

This message describes the current revocationIPv6routing

the route described in this packet may be throughimportbow

NO.86 In BGP4+, what is the content of the next hop network address field carried in the P_REA, CHLRI attribute in the Update packet?

Can only be a global unicast address

can just be a link-local address

Can carry link-local addresses and global unicast addresses at the same time

Only link-local addresses

NO.87 In an MPLS VPN network, data packets are forwarded when they enter the public network. will be encapsulated with two layers of MPLS labels sign. Which of the following options describes the processing of the packet correctly:

The data packet is forwarded toEgress PEequipment

Egress PEThe device correctly sends the data packet to the correspondingVPNmiddle

the outer label of the packet received by the penultimate hop device is3

Egress PEDevice received untaggedIPdata pack

NO.88 The RR rules for advertising routes break the IBGP split horizon rules, so it may cause loops in the AS.
What routing attributes does RR use to prevent loops? (Multiple choice)

Cluster List

Originator ID

Next hop

AS-PATH

NO.89 Which of the following statements about the MP_REACH_NLRI attribute of BGP4+ is correct? (Multiple choice)

The length of the next hop address can be 16 or 3

The value of AFI (address family) is 2, which represents IPv6

The NLRI field carries IPv6 routing prefix and mask information

When the length of the next hop address is 16, the Network Address of Next Hop carries the link local address

NO.90 The Discovery message of LDP is used for neighbor discovery, and LDP has different discovery mechanisms when discovering neighbors. Then, which of the following statements about Discovery message in the basic discovery mechanism is correct? (Multiple choice)

After the TCP connection is established, the LSR does not continue to send Hello Message

The destination IP address of the message is the multicast IP address 224.0.0.2

This message is encapsulated in a UDP message, and the destination port number is 646

The message is sent to the designated LDP Peer

NO.91 SFFv2 is an IGP running on an IPv4 network: 0SPFV3 is an IGP running on an IPv6 network. Compared with 0SPFV2, SPFV3 has a similar LSA type, but has slightly different functions. Which of the following is not included in the LSA type of 0SPFV3?

AS-External-LSA

Router-LSA

ASBR-Summary-LSA

Network-LSA

NO.92 the configuration file of the device. Is the following statement D wrong?

Regardless of whether the device is configured with apricotBPDU Tunnel,neither will be correctMSTPmake an impact

Port connected to user terminal equipmentMSTPWhether it is disabled or configured as an edge port

Check port configuration to confirm enableMSTPWhether the port is enabled with the protocol packet sending command. Such as:bpdu enable

Check if the port is added to the correct oneWLAN

NO.93 If the temperature of the device is found to be too high, it can be concluded that the fan has failed

True

False

NO.94 What is the value of OSPF and BFD linkage?

The hello sending interval of OSPF is at the second level, which is faster than BFD inductive link state

The sending interval of BFD packets can reach the millisecond level, which is slower than the OSPF inductive link state

Through the BFD detected at the millisecond level, the OSPF status is associated to achieve the purpose of OSPF quickly inductive link state

Any change in the BFD status will not affect the OSPF neighbor status
