Which of the following is incorrect about HTTPS?( Multiple Choice)  HTTPS secures access to data by using SSLVPN.  If the HTTPS traffic contains a virus, the router cannot detect the virus directly using IPS technology  When using HTTPS to access a website, the website cannot be accessed if the user’s browser does not recognize the website’s digital certificate.  HTTPS protocol uses TCP port 443 by default Q194. The following description of Filter-Policy is correct?( Radio neck).  With Filter-Policy, on ASBR in OSPF, you can filter the generation of type5 LSA and type7LSA.  Prefix lists can be used to filter both routes and packets.  Filter-policy filters the link state information received or published, and can modify the properties of route entries.  When using a prefix list to filter routes, the table entry ip-prefix 1 deny 0000 0 less-equal32 matches only the default route. Q195. The duplicate address detection feature for NDP in the following description is incorrect?  IPv6 unicast address is called a tentative address after it is assigned to an interface and before it is detected by duplicate addresses  Duplicate address detection is implemented via RS and RA messages  IPv6 duplicate address detection technology is similar to free ARP in IPv4  The interface needs to perform duplicate address detection before enabling any of the unicast IPv6 addresses Q196. What is the following description of MPLS incorrect?  The length of the MPLS tag is 20 to 20 for packet forwarding.  The tag space range of dynamic signaling protocols such as LDP, M P-BGP is 16 to 1023  When using the TTL processing method of Pipe mode, the IP packet transmits the TTL of the IP packet over the IPLS network. The value is only minus 1 for the MPLS in and out nodes.  MPLS supports multi-layer label nesting, and the S bit value of the innermost label is 1. Q197. The following statement about static VXLAN tunnel configuration is correct?  A BD needs to create an NVE country, and when there are multiple BDs, multiple NVE interfaces must be created  An NVE interface can be associated with multiple VNls, so you can create only one NVE interface when there are multiple BDs  For a VXLAN tunnel, you need to create a corresponding NVE interface, in which you explicitly specify the source IP address and the destination IP address , so there are multiple VXLAN tunnels on the VTEP that must be vE interfaces The destination address of the VXLAN tunnel is specified in the  NVE interface, and multiple VXLAN tunnels can create only one NVE interface Q198. As shown in the following figure, R1 and R2 establish a neighbor relationship for Level2, which is critical:placed as follows, then the following about The route entry for R2 is correct  The 0:/64 router appears in the IP routing table  2022:/64 Routers appear in the IP routing table c.2019::/64 Routers appear in the P routing table  2021:-/64 Router will appear in the P routing table Q199.

If the Interface Sticky MAC function is enabled, what is the number of MAC addresses that the interface learns by default?  15  10  5  1 Q201. What kind of scenario can use AS-path-filter?( Multiple select).  A Filters routes received from BGP neighbors based on the AS PATH attribute carried by the route, such as the command peer X.x.x.x as path-filter import  The apply clause in Route policy  Filter routes sent to BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peer x.x.x.x as path-filter export  The if-match clause in Route-policy Q202. In the multi-level RR scenario, the first-level RR will be connected to a large number of second-level R, which may cause the BGP circuit of the first-level RR to overflow from the table Risk of R BGP routing table overflow?( Radio).  ORF  Route Control  Route Aggregation  Set the same Cluster-ID Q203. If you have a Huawei switch running the STP protocol, and now connect the GO/O/17 interface and the GO/O/18 interface of the switch through a cable, then the scenario described below is correct ?( Single choice questions).  Both the G0/0/17 interface and the GO/0/18 interface enter the Forwarding state  Both the Go/0/17 interface and the G0/0/18 interface enter the Disccarding state  The Go/0/17 interface enters the Blocking state  The GO/0/18 interface will continuously change back and forth between the Listening state and the Learning state  GO/0/18 interface will enter the Disking state Q204. There is a new HW office that needs to use their router as a DHCP server. When configuring the DHCP server to provide DHCP services to the current office, what of the following items need to be configured?  Exclude unused IP addresses from the DHCP server  Configure the timeout period for ping packets  Configure the startup file for the DHCP server  Configure manual binding  Configure dhcp address pool Q205. What messages does an NMS (Network Management Station) running SNMPV1 send to the agent?  Trap,Get ? Set  Get, Set ?Getnext  Get,Set,Getnext ? GetBulk  Get,Set ? GetBulk  ? Trap Q206. Which of the following routing tools is unique to BGP?  Route-policy  ACL  IP-prefix  AS-path-filter Q207. Both the CSNP packet of ISlS and the DD packet of OSPF have a role in the MA network, describing the role of the link state database summary, which is correct compared to the following statements of these two types of messages  Both packets need to be confirmed to the terminal router after being sent, otherwise they need to be retransmitted  Once the adjacency relationship is established, the CSRP packet and the D message will stop sending  The two packets do not need to be confirmed to the router after they are sent the master-slave relationship in the DD message interaction of  OSPF is not identity bound to dr/BDR; the CSN message is generated only by DIS Q208. The rules for RR to publish routes break the rules for horizontal segmentation of IBGP, so it is possible to cause loops within the AS. What routing attributes does RR use to prevent loops?  Nexthop  Originator ID  AS-PATH  Cluster List Q209. Is the following description of the OSPFv3 message correct?  The interface ID of the sending interface must be included in the A Hello packet  The LSACK message contains LSA header information to confirm the receipt of LSU packets  The LSR message contains the complete LSA header information for requesting an update to the LSA  Hello messages and the Option field for DD messages extends to 24-bit Q210. As shown in the figure, the PPP link between R1 and R2 is not in the same network segment, but the R1 and R2 direct connectors can communicate, and the Ethernet link cannot communicate under the same planning, why?  The interconnect POS ports of R1 and R2 learn the 24-bit subnet route of each other’s direct connection ports through IPCP  The interconnect POS ports of R1 and R2 learn the 32-bit host route for each other’s direct connections through IPCP  The interconnect POS port of RI and R2, through LCP learns the MAC address of the opposite termination , does not need to use ARP to request the MAC address  The data packets of the interconnect POS ports of R1 and R2 do not need to encapsulate ethernet headers and do not need to use ARP to request MAC addresses Q211. The following is correct about the LSA of OSPFv3  The Link State ID of inter-area prefix-SA, which contains prefix information  Router-LSA and Network-LSA do not contain routing information  When the Referenced Link State Type-2 of the Intra-AreaPrefixLSA, referenced Link State ID Contains the interface ID of the DR  Inter-Area PrefirLSA also contains LinkLocal Information Q212. What are the ways to divide VLANs in Huawei switches?

The following statement about OSPF route filtering is incorrect.( Single choice questions).  In the NSSA area, filtering for external route ingestion and advertisement can be configured on ASBR or ABR  Filtering for the three types of LSAs needs to be configured on the ABR across OSPF regions  Interface-based filtering of LSAs allows all LSAs in the inbound and outbound directions except grace LSAs  Based on the link state database, when calculating routes, the fiter-policy import command is used, which only affects the route addition in the route table, and has no effect on the OSPF link state database Q215. In SSM, what version of IGMP is required?  IGMPV3  IGMPV4  IGMPV2  IGMPV1 Q216. What does IPV6 enable topology ipv6 mean under IS-IS protocol view?  Does not have any meaning  SPF calculation for IPv6 is not supported  SPF calculation is performed separately in the topology of IPv4 and IPv6,  IPv4, IPv6 using the same topology for SPF calculation Q217. The correct description of the extended features of ISIS is ?  When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information.  ISIS can choose whether to authenticate incoming SNP and LSP packets  If there are other vendors’ devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors’ devices.  After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process.  Loading … Free Sales Ending Soon - 100% Valid H12-891_V1.0 Exam: https://www.exams4sures.com/Huawei/H12-891_V1.0-practice-exam-dumps.html --------------------------------------------------- Images: https://free.exams4sures.com/wp-content/plugins/watu/loading.gif https://free.exams4sures.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-09-06 15:00:05 Post date GMT: 2022-09-06 15:00:05 Post modified date: 2022-09-06 15:00:05 Post modified date GMT: 2022-09-06 15:00:05
