Huawei H12-831_V1.0 Dumps Updated Aug 07, 2022 WIith 265 Questions [Q45-Q66]

NO.45 Deployment in a small and medium-sized networkOSPF,When viewing the routing table of a device, it is found that there are only directly connected routes.
It is not possible for the operation to cause the fault?

NO.46 Traditional BGP4 can only manage IPv4 unicast routing information. In order to provide support for multiple network layer protocols, MP-BGP extends BGP-4.
MP-BGP uses address families to distinguish different network layer protocols. Which of the following address families are currently supported? (Multiple choice)

NO.47 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

NO.48 Which of the following commands can be used to view BGP VPNv4 routing and BGP private network routing information on PE?

NO.49 What check items can be set in IPSG? (Multiple choice)

NO.50 Ethernet is a network that supports broadcasting. Once there is a loop in the network, this simple broadcasting mechanism will cause catastrophic consequences.
Which of the following phenomena may be caused by loops? (Multiple choice)

NO.51 The routing policy tools that can be used by BGP mainly include Filterpolicy and oRoute-policy.
Fiterpolicy can only filter routes, Rote – policy can only modify routes

NO.52 As shown in the figure, Sitel and Site2 need to achieve mutual access through the operator’s BGP/MPLS IPVPN. A known The public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has The 192.168.1.0/24 network segment route is advertised to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal. When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Sitel, the outermost label What should the sign be?

FEC In/Out label
1.1.1.1/32 6662/3

NO.53 About the site in the BGPIMPLS IP VPN network architecture. Which of the following descriptions is correct?

NO.54 In 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?

NO.55 As shown in the figure, the cost value of the link that all interfaces of the router enable OSPF is identified in the figure. Loogback0 interfect of R2 is advertised in area 0. In area 1, both R2 and R3 will be transmitted in the form of Typae3 LSA 10.0.2.2/32 routing information.

NO.56 In the intra-domain MPLS VPN network, when the data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Regarding the description of the two layers of labels, which of the following options is wrong?

NO.57 An engineer uses two routers to test IPv6 services, and runs 0SPFv3 to implement IPv6 network interconnection.
R1 is required to be able to access the loopback interface address of R2.
The engineer checked the OSPFv3 routing table entry of R1, as shown in the figure, and found that there was no route to the loopback interface address of R2. Which of the following reasons could not be the cause?

NO.58 As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy After modifying the Local Preference value, you can control the path of traffic leaving the AS100

NO.59 When troubleshooting MSTP, you executed the display current-configuration command to obtain the configuration file of the device. Which of the following statements is wrong?

NO.60 Which of the following descriptions about MPLS header TTL are correct? (Multiple choice)

NO.61 From this figure, we can conclude that

NO.62 By default, which of the following secure MAC address types will be lost after the device restarts?

NO.63 To speed up the detection of link failures in an IS-IS network, you can associate IS-IS with BFD.

NO.64 Through the display ip interface GE0/D/D command, you can view the statistics of ping packets received on this interface.

NO.65 How many bits are there in the label field of PLS?

NO.66 The description of the MPLS forwarding mechanism is correct
