Inconsistent message sending interval  interfaceIPInconsistent address masks QUESTION 33MPLS has the concept of FEC forwarding equivalence class, so FEC cannot be allocated based on which of the following standards?  Class of Service  Fragment of fiset  Application Protocol  Destination Addess QUESTION 34After the cutover is completeD. it is generally necessary to check the following items?  Software version  physical topology  data flow  control plane entry QUESTION 35Regarding the BGPI MPLS IPVPN network architecture, which of the following descriptions is wrong?  The P device only needs to have basic MPLS forwarding capabilities and does not maintain VPN related information  Sites can visit each other through VPN, and a site can only belong to 1 VPN  Under normal circumstances, CE equipment does not perceive the existence of VPN, and CE equipment does not need to support MPLS, MP-BGP, etc.  The BGP/MPLS IP VPN network architecture consists of three parts: CE (Customer Edge), PE (ProviderEdge), and P (Provider). PE and P are operator equipment, and CE is BGP/MPLS IPVPN user equipment. QUESTION 36In PLSVPN, in order to distinguish IPv4 prefixes that use the same address space, the value of R0 is added to the IPv4 address. The correct description of the following options is:  On a PE device, each VP instance corresponds to a value of 0. On the same PE device, the RD value must be unique.____, ____, ____.  RD can be used to control the publication of 1 routing information  RD is encapsulated in Update message as BGP extended community attribute during delivery  After the PE receives the IPv4 route from the CE, it adds RD to the IPv4 route to convert it into a globally unique VPN-IPv4 route, and publishes it on the public network QUESTION 37Compared with the OSPFv2 message header, what fields are added in the OSPFv3 message header?  IPV6 Auth Type  Link ID  Instance ID  IPV6 Router ID QUESTION 38As 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 39As shown in the figure, OSPF is deployed in a campus, and Area 1 is deployed as an NSSA area. By default, R2 will automatically generate a Type 7 LSA default route and flood it in the NSSA area.  TRUE  FALSE QUESTION 40As shown in the figure, the entire network of a certain company uses OSPF to get through the network. However, RouterS and RouterE cannot establish an OSPF neighbor relationship. When detecting OSPF failures, network administrators can execute the display ospf 100 () interface GEO/0/1 command on RouterS to obtain error-related information. Users can perform OSPF failure diagnosis based on this information. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated) errorQUESTION 41An engineer uses two routers to test IPv6 services, and simulates the interconnection between the headquarters and branches by running BGP4+. The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between the two devices, which of the following Is a statement wrong?  The Next_Hop attribute must be an IPv6 global unicast address when routing  BGP4+ transmits routing information between peers through Update packets  If the MP_REA, CH_NLRI attribute is carried in the Update packet, it indicates that the advertisement is a reachable route  When the route is transmitted, it will carry recognized mandatory attributes such as AS_Path QUESTION 42What is wrong with this configuration description is:[Huawei]dhcp enable[Huaweijinte GigabitEthernet 0/0/1 [Huawei-GigabitEthernet0/0/1 ]dhcp option82 insert en [Huawei-GigabitEthernet0/0/1 ]dhcp snooping enable [Huawei-GigabitEthernet0/0/1]dhcp snooping trusted  ifGigabitEthemnetOIO/1received by the interfaceDHCPIn the request message, there is noOption82of SutOptioninformation, the device will generateOption82,and insert it into the message  turn onDHCP Snoopingconfiguration can be used to preventDHCP ServerCounterfeiter Attack  configureGigabitEthernetO/0/lThe interface is a trusted interface  turn onDHCP Snoopingconfiguration can be used to preventARPspoofing attack QUESTION 43As shown in the figure, the operator’s BGP/MPLS IP VPN backbone network builds SP through DP. If you want to implement user X If the two sites communicate through the BGP/MPLS IPVPN network, PE1 and PE2 must use a 32-bit masked loopback interface address to establish an MP-IBGP peer relationship.  True  False QUESTION 44As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator’s BGP/MPLS IPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has advertised the 192.168.1.0/24 network segment route in Site1 to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal.When capturing the data that Site2 visits the 192.168.1.0/24 of Site1 between P and PE1, what should be the outermost label?  6661  3  6662  8888 QUESTION 45The network administrator A wants to use ACL to match only the four routing entries 1, 3.5, and 7 in the figure. How many ACL rules does the network administrator A need to configure at least?  2  1  4  3 QUESTION 46In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate the wide recruitment area, and these Sub-VLANs are aggregated into a logical Super-VLAN. A company divides different departments into different Sub-VLANs because of the Sub-VLAN. VLAN not only includes physical connections, but also can establish a three-layer VLANIF interface, which can directly communicate with the external network on the three-layer.  TRUE  FALSE QUESTION 47From the user’s point of view, any phenomenon that affects the business can be defined as a failure.  TRUE  FALSE QUESTION 48multiple equal-cost routes may appear. About the IS-IS network , which of the following descriptions is false?  When the number of equal-cost routes in the network is greater than the number configured by commands, and these routes have the same priority, the next-hop device is preferredSystem IDLarge routes for load balancing  If load sharing is configureD. the traffic will be evenly distributed to each link  After configuring equal-cost route priorityJS-ISWhen the device forwards the traffic reaching the destination network segment, it will not adopt the load balancing methoD. but forward the traffic to the next hop with the highest priority  For each route in the equal-cost route, a priority can be specifieD. and the route with higher priority will be preferred. the rest as backup routes  Loading … H12-831_V1.0-ENU Exam Questions and Valid PMP Dumps PDF: https://www.test4engine.com/H12-831_V1.0-ENU_exam-latest-braindumps.html --------------------------------------------------- Images: https://blog.test4engine.com/wp-content/plugins/watu/loading.gif https://blog.test4engine.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-05-05 16:37:49 Post date GMT: 2022-05-05 16:37:49 Post modified date: 2022-05-05 16:37:49 Post modified date GMT: 2022-05-05 16:37:49
