Which of the following descriptions is wrong? (Multiple choice)  MPLS classifies packets with the same forwarding processing method into one category, which is called FEC  A forwarding equivalence FEC will be assigned a unique label value on all routers  The packets of the same FEC will be processed differently in the MPLS network  The division of FEC is very flexible. It can be based on any combination of source address, address, source port, destination port, protocol type or VPN, etc. QUESTION 135EGP authentication can prevent illegal routers from establishing neighbors with BCP routers.

(Multiple choice)  Each Group VLAN must be bound to a Principal VLAN  Separate VLAN can communicate with all VLANs in MUX VLAN  Each Separate VLAN must be bound to a Principal VLAN  Principal VLAN can communicate with all VLANs in MUX VLAI QUESTION 141Regarding multi-instance CE (Mlulti-VPN-Instance CE, MCE), which of the following descriptions is wrong?  existMCEdevice needs to be differentVPNCreate their own routing table and bind to the correct interface  connected to the sameMCEbut not oneVPNInstance users cannot access each other  haveMCEfunctional devices can be found inBGPIMPLS IP VPNAccess to multiple applicationsVPNExample, reduce the investment of user network equipment  MCEandPEThere must be multiple physical links betweenVPINIsolation between instances QUESTION 142Which of the following series can be matched by the regular expression 100.S? (Multiple choice)  100  1000  10000  1001 QUESTION 143Regarding BGP/MPLS IPVPN routing interaction, which of the following descriptions is wrong?  The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routing  After the egress PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route  The exchange between PE and CE is IPv4 routing information  The ingress PE changes the IPv4 route received from CE to VPNv4 route, and saves it according to different VPN instances QUESTION 144The IS-IS neighbor relationship between R3 and R1 is not established. According to the information in this figure, what is the possible reason?  R3andR1ofIIHAuthentication failed  R3andR1ofSystem IDrepeat  R3andR1ofI5-LevelMismatch  R3andR1the interconnect interfacecircuit-typeMismatchWhen troubleshooting MSTP faults, you executed the display current-configuration command to obtain QUESTION 145MPLS is called multi-protocol label switching. Which description is correct about the label in MPLS? (Multiple choice)  MPLS system has a variety of label publishing protocols, such as LDP is a label publishing protocol  The label is carried by the header of the MIPLS message and has a global meaning, that is, the label value of all routers cannot be repeated  A label is an identifier with a fixed length and only local meaning, which is used to uniquely identify the FEC to which a group belongs  MPLS supports single-layer labels as well as multi-layer labels QUESTION 146Display interface GE0/0/0 once, and find that the Total Eror count (the total number of error packets on the physical layer of the interface) is not 0. At this point, it can be concluded that the current fault has not disappeared.  TRUE  FALSE QUESTION 147BFD session down will cause the direct link to fail.  TRUE  FALSE QUESTION 148A certain park deployed both IPv4 and IPv6 networks for service testing, and IS-IS was run to achieve network interconnection. IS-IS routing protocol has good scalability and is widely used in existing networks.Regarding IS-IS scalability, which of the following statements are correct? (Multiple choice)  IS-IS uses TLV structure to construct messages, which makes IS-IS more flexible and expandable  For IS-IS, adding new features only needs to add a new TLV  IS-IS needs to add TLV to carry Pv6 address information in order to support PV6  NLPID is a new TLV of IS-IS to support IPv6 QUESTION 149Which of the following statements is true about the role of ping and tracert?  Pingthrough one-wayicmp echo requestPacket inspection and bidirectional reachability of the correct end  TracertMust be able to trace every hop from source to destinationIPaddress  pingThe reachability from the local end to the peer end is verifieD. but it does not mean that the peer end to the local end must be reachable  tracertandpingThe function is the same, just the name is different QUESTION 150A campus has deployed IPv6 for service testing. There are 4 routers in the network, running 0SPFv3 to implement IPv6 network interconnection. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Which of the following statements is true about the description of this LSA?  The router that generates this LSA is R2 port R2 connected  IPv6 address prefix for GEO/0/0: 2001:DB8:2345:23::/64  The link-local address of R2 interface GEO/0/0 is: FE80::2E0:FCFF:FEC, D:4F79  The SA shows 2 does not support external routing, but participates in IPv6 routing calculation QUESTION 151Which of the following descriptions is wrong?  The LSP established by statically assigning labels can also be dynamically adjusted according to network topology changes without the intervention of the administrator  The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node  LSP is divided into static LSP and dynamic LSP. The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol  Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE, LDP QUESTION 152Configuring DHCP Snooping can be used to prevent imitator attacks, so the configuration process needs to include the following What are the steps?  enable globalDHCP SnoopingFunction  enable globalDHCPFunction  Configure Interface Trust Status  enable interface orVLANofDHCP SnoopingFunction  Loading … New (2022) Huawei H12-831_V1.0-ENU Exam Dumps: https://www.braindumpsit.com/H12-831_V1.0-ENU_real-exam.html --------------------------------------------------- Images: https://blog.braindumpsit.com/wp-content/plugins/watu/loading.gif https://blog.braindumpsit.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-05-23 15:15:45 Post date GMT: 2022-05-23 15:15:45 Post modified date: 2022-05-23 15:15:45 Post modified date GMT: 2022-05-23 15:15:45
