QUESTION 79
The Route-LSA generated by a router is shown in the figure. Which of the following descriptions are correct? (Multiple choice)

QUESTION 80
In the network shown in the figure, the OSPF protocol is deployed between R2 and R1, and the IS-IS protocol is deployed between R2 and R3. In order for R1 to obtain the route to 10.0.3.3/32, the IS-IS route is introduced into the OSPF route on R2. The FA address in the Type5 LSA generated by R2 is ().

QUESTION 81
In the OSPFv3 network shown in the figure, there are _______ Link-LSAs in R1’s LSDB.

QUESTION 82
When the administrator statically configures the Ingress node of LSP, it is recommended to establish a static LSP by specifying the next hop to ensure that there is a routing entry in the local routing table that exactly matches the specified destination IP address.

QUESTION 83
Which of the following statements about the OSPFv3 message format is correct? (Multiple choice)

QUESTION 84
In the figure, a network administrator configures a static LSP to implement MPLS data forwarding . The lower part of the topology shows the packet header information obtained from a device.
Which of the following statements are true ?

Options:

QUESTION 85
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS, and the area number is
49.0001. R3 and R6 run IS-IS, and the area number is 49.0002. Within AS 65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, where R2 and R5 are RRs and R1, R4, R3, and R6 are clients. IBGP neighbor relationships are all established using the Loopback0 interface. R2 and R5 also establish an IBG neighbor relationship. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.XX, where X is the device number. R1 and R4 introduce the external network 192.168.0/24 into BGP through import.

For 192.168.1.0/24, match the number of valid routes in the display bgp routing-table output.

QUESTION 86
The ORF function of BGP can control the routing entries sent by neighbors. In order to achieve this purpose, the BGP router will send the list of routes to be filtered to the neighbors. Which tool is generally used to send the list to the neighbors?

QUESTION 87
Which of the following Community attributes can ensure that the propagation range of BGP routing entries is only within the AS? (Multiple choice)

QUESTION 88
What characteristics must a high-risk operation plan have?

QUESTION 89
After executing reset isis all, the IS-Is protocol process needs to be restarted and neighbors need to be re-established, and various IS-IS statistics will not be cleared.

QUESTION 90
The figure shows the debugging information on an OSPF router. Which of the following is the router ID of this router?

QUESTION 91
As shown in the figure, OSPF is deployed in a campus, and Area 1 is deployed as an NSSA are a. In the case of missing header, R2 will automatically generate a missing header route of Type 7 LSA and flood it in the NSSA area

QUESTION 92
Which of the following reasons may cause the hosts in the same VLAN of the LAN to fail to communicate with each other?

QUESTION 93
An administrator runs the display mpls Isp command to view LSPs on a device. The command output is shown in the figure. Which of the following statements are true?

QUESTION 94
A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled, and function as the gateways of PCI and PC2, respectively. Given this, which of the following statements is false?

QUESTION 95
After troubleshooting the problem, the network engineer wrote a troubleshooting report, in which he simplified the actual networking into the network shown in the figure.

In the faulty network, R1 and R2 both enable OSPF and serve as gateways for PC1 and PC2 respectively. Which of the following descriptions of the faulty network connectivity are correct?
(Multiple choice)

QUESTION 96
In an MPLS domain, LSR can be divided into Ingress LSR, Transit LSR and Egress LSR according to the way the LSR processes data. For the same FEC, a certain LSR can be the Ingress LSR of the FEC or the Transit LSR of the FEC.

QUESTION 97
On the IS-IS IPv6 network shown in the figure, multi-topology is enabled on all routers.
The ipv6 default-route-advertise always level-1 command is configured in the IS-IS process of R4.

Which of the following routers does not have the default route in its routing table?

QUESTION 98
In the hub-spoke networking shown in the figure, which of the following commands must be configured on the Hub-PE to ensure correct route transmission?

QUESTION 99
