Based on this, determine which reason causes the adjacency relationship to fail to be established normally?  Authentication password is not-consistent  Regional type is not-consistent  The interval for sending Hello messages is not-consistent  The IP address mask of the interface is not-consistent QUESTION 74IEIF has extended the functions of OSPF by taking advantage of the strong scalability of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3, and OSPFv3 is compatible with OSPFv2.  TRUE  FALSE QUESTION 75As shown in the figure, all interfaces of the router enable OSPF. The IP address identified in the figure is the IP address of the oopback0 interface of the device. Loopback0 of R1 and R2 is advertised in area 1, Loopback0 of R4 is advertised in area 0, and Loopback0 of R3 and R5E are advertised in area 2, which of the following IP addresses can ping each other? (Multiple choice)  10.0.2.2 and 10.0.3.3. (Not counted when receiving Category 3 in non-backbone areas)  10.0.3.3 and 10.0.5.5 (Class 1 in the same area)  10.0.4.4 and 10.0.2.2. (3 types of normal calculation)  10.0.2.2 and 10.0.5.5 (not counted when receiving Category 3 in non-backbone areas) QUESTION 76Regarding the description of the encapsulation format of labels in MPLS, the correct one is  MPLSThe total length of a single label is4bytes(32bits)  For Ethernet,PPPpacket, the tag stack is like ‘shim*-between the L2 header and the data: yesVLAN tagTime,MPLShead on the ether head withVLAN tagbetween  in the labelSfield:lbit,Used to identify whether the label is the bottom label of the stack, the value is1is indicated as the penultimate layer label  in the labelTTLfields andIPgroupedTTL( Time To Live.,time-to-live) is similar in meaning and also has the effect of preventing loops QUESTION 77From this picture, we can judge  If not configured aboutAS_Pathrouting strategy, then3002:-4/128 -must not originate from AS 65001  R1does not have3002:3/128and3002.-4/128routing  R1have3002.-3/128and3002:.4/128routing  If not configured aboutAS_Pashrouting strategy, then3002:4/28must have originated from AS 65001 QUESTION 78In an operator’s MPLSVPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route on PE1 and assigns a label of 1027 Released to PE2. The outgoing label of the MPLS LSR-ID of PE2 reaching PE1 is 1025o When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be a combination of the following 6 options?  outer layer label:1025:inner label:1027  outer layer label:1027:inner label:1027  Layer Label:1027:inner label:1025  Layer Label,1025:inner label:1025 QUESTION 79The router ID of OSPF V3 needs to be configured in dotted decimal with a length of 128 bits.  True  False QUESTION 80OSPFv2 is an IGP running on an IPv4 network; OSPFv3 is an IGP running on an IPv6 network. The basic working mechanism of OSPFv3 is the same as OSPFv2, such as the election of DR and BDR. As shown in the figure, an engineer uses three routers to test IPv6 services. He wants to realize the interconnection and interoperability of IPv6 networks by running OSPFv3.Which of the following statements regarding the election of DR on this network is correct?  After the network converges, the engineer changes the priority of R1 to 100, the priority of R2 to 10, and the default value of R3. When the network converges again, R1 is DR and R2 is BDR  After the network converges, a new device R4 is added to the broadcast link, and the priority of R4 is 150. When the network converges again, R4 is the DR  After the network converges, R1 is powered off and restarted. When the network converges again, R3 is the DR  After the network converges, R1 is the DR QUESTION 81Which of the following descriptions is correct about configuring static LSPs in MPLS networks?  when a certainLSRforEgress LSR, you only need to configureIn Label,The range is 16-1023  when a certainLSRforTransit LSR, you need to configureIn LabelandOut labeljn LabelThe range is 16~1023,Out LabelThe range is16~1048575  when a certainLSRforTransit LSRneed to be configured at the same timeIn LabelandOut Label,The range is 16-1023  when a certainLSRforIngress LSR, just configureOut Label,The range is 16~1048575 QUESTION 82Configure under a certain interface: isis timer hello 5 leve1-2, which of the following statements is correct?  The interval for sending Level-2 hello packets on this interface is 5s  The hello packet sending interval of Level-1 and Leval-2 of this interface is 3s.  The interval for sending Level-2 CSNP packets of this interface is 5s  The interval for sending Level-1 hello packets on this interface is 5s QUESTION 83According to the configuration shown in the figure below, you can know that R4 has an interface advertised into IS-IS?  1  3  2  0 QUESTION 84According to this picture, the door can be judged?  R4belong only toLevel-2  system-IDforee8c.a0c2.baf2device whose type isLevel-1-2  system-IDforee8a0c2.baf2device whose type isLevel-1  R4belong only toLevel-1 QUESTION 85Ethernet is a broadcast-enabled network, and once there are loops in the network, this simple factory broadcast mechanism can have disastrous consequences. Which of the following phenomena may be caused by loops?  CPUOccupancy exceeds70%  The device cannot log in remotely  use on devicedisplay interfaceWhen commanding to view interface statistics, it is found that the interface receives a large number of broadcast packets  pass throughpingSerious packet loss during network test with command QUESTION 86The routing attributes of the three routing entries are shown in the figure. Assuming that the next hops of the three routing entries are all reachable, when these three routing entries are After the entries arrive at the BP router in order, by default, BGP will finally call a route entry?  Route B  Route C  Route A  slightly QUESTION 87As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy After modifying the MED value, you can control the path of traffic entering the AS100  True  False QUESTION 88As shown in the figure, MPLS LSP is configured in the network, and the goal is to establish an LDP session between SWA and SWB, then which of the following statement is correct?  The configuration is correct  No need to enable MPLS globally  No need to enable MPLS on the port  Two devices mpls lsr-id cannot be configured as the same QUESTION 89By default, LDP adjacencies will trigger the establishment of LSP based on the IP routing of the 32bit address.  TRUE  FALSE QUESTION 90Which of the following operations may affect the normal operation of the customer network? (Multiple choice)  Device naming  Software upgrade  Hardware expansion  Routing protocol configuration changes  Loading … Latest Huawei H12-831_V1.0 Real Exam Dumps PDF: https://www.validexam.com/H12-831_V1.0-latest-dumps.html --------------------------------------------------- Images: https://premium.validexam.com/wp-content/plugins/watu/loading.gif https://premium.validexam.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2023-01-13 15:40:16 Post date GMT: 2023-01-13 15:40:16 Post modified date: 2023-01-13 15:40:16 Post modified date GMT: 2023-01-13 15:40:16
