Provide Updated Huawei H12-891_V1.0 Dumps as Practice Test and PDF QUESTION 61In an HWIP multicast network, where multiple sources exist and each source has several receivers, which protocol allows source-to-RP traffic and RP-to-receiver traffic to share the same tree 2?  MOSPF  PIM SM  DVMRP  56768GZliuji  PIM-DM QUESTION 62MQC, like PBR-can only be called under the device’s Layer 3 interface.  TRUE  FALSE QUESTION 63There is an existing switch running the RSTP protocol. If the network topology changes, what happens to the Layer 2 forwarding table that is automatically learned by the switch?  All table entries are dropped  Except for the table entry related to the edge port that is not deleted, all other table entries are deleted  Only table entries related to the port that received the TC message are dropped  If the aging time is set to 15 seconds, entries that exceed the aging time are deleted  Table entries are dropped except for table entries related to edge ports and table entries related to ports that receive TC messages QUESTION 64If you delete a declared route entry on a BGP router, the BGP routing ring is triggered to send an Update message for route scattering, which carries the accepted mandatory attribute of the route entry that was discarded.  True  False QUESTION 65What designs in the router can improve the reliability of the router?  Dual power supply design  Module hot-swappable design  Issu Design  Dual-engine design QUESTION 66What command can be used to prevent users from accessing multiple devices through the HUB on the switch’s access port?( Radio).  [Huawe interface Gigabithemeto/0/1[Huawei-GigabiEthermeto/O/lport linktypetrunk[Huawel-GigabithemetO/1]port trunk allow pass vlan 10  [Huawei interface GigabiEthemet/0/1[Huawe-GigablEthemetO/0/1Jpor ink type acess(Huawei GigabitEthemet/O/Tipsg enable  Huawei interface GigabiEthemetO/0/1Huawei-GigabiEthemetO/OJport link-type acces Huawei GigabilEthemet/0/1port-secunty enable0  [Huawei iterface Gigabithemeto/0/1 (Huawei-GigabitEthemeto//1)pot ink type access(Huawel-CigabiEthemeto/1]portisolate enable QUESTION 67The following statement about isis protocol LSP messages is correct  The isP rapid diffusion feature, which first diffuses out LSPs that are smaller than a specified number , speeding up the synchronization process of LSDB  By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes  As link status information increases, the packet length of the LSP can be increased so that each ISP can carry more information.  Reducing the minimum interval at which LSPs are sent per port can speed up the diffusion of LSPs. QUESTION 68Which of the following DNS resource records are legitimate?  FQDN  NS  PTR  MX  A QUESTION 69A router receives a BGP route with the community attribute NO-Export , how will the router handle the BGP route?  Drop the route directly.  No more advertising to other BGP routers.  Advertise only to IBGP neighbors.  The route is advertised normally, but the route is not used to forward data. QUESTION 70If you have a LOCAL AREA NETWORK running 8021D Spanning Tree Protocol, the non-root switch does not receive which parameter under the root switch?  MaxAge  Root cost  Forward delay  Hold time  Hello time QUESTION 71The following statement about the VPNv4 address is wrongly described as ?  By default, PE does not perform VPN-target filtering on received VPNv4 routes.  Local PE sets up An Export Target for these routes before releasing VPNv4 routes learned from sites that are directly connected to them to other PEEs attributes, and are published with routes as extended community attributes for BGP.  Carries the RD attribute when BGP publishes both reachable and unreachable VPNv4 routes.  The VPNv4 address has a total of 12 bytes, including an 8-byte route identifier RD (Route Distingulisher) and a 4-byte IPv4 Address prefix. QUESTION 72  When sending a packet with a destination address of 4444, it is sent without labeling.  When the router receives a packet with the label 1024, it replaces the label with 1027 and sends it.  When a packet with a destination address of 2 is sent , it is sent without labeling.  When sending a packet with a destination address of 3333, label 1026 and send it. QUESTION 73When configuring ISIS zone authentication, which ISIS message will carry the authentication letter? ( Single choice questions).  ISIS ?Level-1 ?SNP ?LSP?  ISIS ?Level-2 ?SNP ?LSP?  Hello message of ISIS’s Level-1.  Hello message of ISIS’s Level-2 QUESTION 74MSTP switches treat RSTP switches as MSTP domains, MSTP, which are formed by a single switch The interchange resolves the RSTBPDU to MSTBPDU, where IRPC is 0  True  False QUESTION 75As shown in the figure, SWA, SWB runs the PSTP protocol, and Cost of Path remains the default without modification, so the following statement is correct  GEO/0/1 on ASWB is Alternative port  GE0/0/2 on SWB is Alternative port  SWA On GEO/0/1 for backup port  SWB will become the root bridge QUESTION 76If a router only needs to forward iPv6 packets, you do not need to configure any IPV4 agreements and addresses on that router.  True  False QUESTION 77How do 8021w and 8021D handle BPDUs?( Confirmed) The  8021D bridge only forwards BPDU packets received from the root bridge  The 8021D bridge does not forward BPDU messages  The 8021w bridge forwards only BPDU packets received from the root bridge  8021w Bridge does not forward BPDU packet QUESTION 78When the BFD detection intervals on both ends are 30ms and 40ms, are the following options described correctly?  BFD session can be established, which takes 40ms after negotiation A  BFD session can be established, which takes 30ms after negotiation  BFD sessions can be established, each occurring at its own interval  BFD sessions cannot be established QUESTION 79What kind of scenario can use AS one path and one filter?  Filter routes received from BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peer x.X.x.x as path-filter import  The apply clause in Routepolicy  Filter routes sent to BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peerx. X.x.x as path-filter export  If-natch clause answer in Route-policy. QUESTION 80Assume that BGP/MPLSIPVVPN, OSPF, LDP, and static routing protocols are already enabled on the PE router . Which of the following protocols need to enable GR on PE in order to get NSF functionality?(Multiple choice questions).  BGP  Static circuit  OSPF  MPLS LDP QUESTION 81The router is running both OSPFv3 and ISIS, and the OSPFv3 route needs to be introduced to ISIS, which of the following ingestion configurations is correct:( Multiple choice questions).  Huawel ias 1 ltuawei-i- isHeveleve!. l Huave-s-1 networkenity 47001.0000020 Hawe -sis-1 ipv6enabletopolog standard Htuawer is-] pob impot.  (Huawei isis l Huawei-si-1 s-levelve!-l Huavei- ti.-1] networkentiy4 .001.00001.
