H12-821_V1.0 exam is designed to test the skills and knowledge required for the design and implementation of data communication networks using Huawei technologies. H12-821_V1.0 exam covers a wide range of topics, including network architecture, network protocols, network security, and network maintenance.   Q13. Which of the following statements regarding OSPF route summarization is false?  OSPF supports two route summarization modes: ABR summarization and ASBR summarization.  Any router in OSPF can summarize routes.  Route summarization is the process of summarizing routes with the same prefix into one route and then advertising only the summarized route to other areas.  Route summarization can reduce routing information, decrease the routing table size, and improve router performance. Q14. A switch runs MSTP. The configuration is shown in the figure. What is the role of this switch in MSTI 1?  Uncertain  Root switch  Non-root switch  Secondary root switch Q15. OSPF supports area authentication and interface authentication. If both authentication modes are configured, Interface authentication takes preference over area authentication.  TRUE  FALSE Q16. RSTP provides different functions in different scenarios. Which of the following statements Is false?  After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period  The role of the designated port that is enabled with root protection cannot be changed  If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation  When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state Q17. To prevent inter-area routing loops, OSPF does not allow advertising routing information between two non-backbone areas and allows sing routing information only within an area or between the backbone area and a non-backbone area. Therefore, each ABR must be connected to the backbone area.  TRUE  FALSE Q18. Which of the following statements about multicast packet forwarding is true?  If a multicast data packet fails the RPF check, the packet must have been received through a sub-optimal interface. However, this interface still receives and forwards the multicast traffic downstream.  IGMP snooping cannot control the scope of multicast traffic flooding on a Layer 2 network.  The source address of a multicast packet is a unicast address.  In multicast transmission, the destination address of a packet can be the unicast address of a host. Q19. The Interface P address and VRRP virtual IP address can be the same.  TRUE  FALSE Q20. Which Of the following IEEE 802.11 standards is also known as Wi-Fi 6?  802.11ac  802.11n  802.11ax  802.11b Q21. When two routers exchange LSDB information using DD packets, a master/slave relationship is formed first, the router with a larger router ID is the master, and determine the MS bit.  TRUE  FALSE Q22. The filter-policy 2000 export command is run in an ISIS process. Which of the following statements about the functions of a filter policy is false?  Is used together with the route import function to advertise some imported external routes to neighbors.  If this command is not run, the device by default advertises all routes that ISIS Imports form external routing protocols.  Controls the advertisement of routes generated by the device.  Filters LSPs to be advertised. Q23. Which of the following attribute must be carried in an Update message?  Local-pref  Prefval  MED  AS-Path Q24. What is the correct procedure for a VLAN pool to assign terminals to VLANs. Q25. Which of the following statements regarding the summary automatic command and BGP route summarization is false?  After this command is configured, BGP sends only the summarized routes to peers  This command is used to implement automatic summarization. Automatic summarization takes precedence over manual summarization  This command enables automatic summarization for the locally imported routes  After this command is configured, BGP summarizes routes based on natural network segments Q26. Which of the following statements regarding IGMPv1 and IGMPv2 are true?  1GMPv2 supports only general query.  1GMPv2 defines the Leave message type.  IGMPv1 does not define the IGMP Leave message type.  IGMPv1 supports general query. Q27. To inject IGP routes into BGP routes, you can only use the network command.  TRUE  FALSE Q28. Which of the following statements about WLAN roaming are true?  APs for roaming do not need to have overlapping signal coverage.  APs for roaming must be in the same extended service set (ESS).  APs for roaming must have overlapping signal coverage.  APs for roaming must be in the same basic service set (BSS). Q29. The traffic limiting policy feature only supports the number of connections initiated by the specified IP or the number of connections received.  TRUE  FALSE Q30. An engineer sets the CAPWAP heartbeat detection interval to 20 of the active link before an active/standby switchover occurs?  75s  20s  60s  90s Q31. Regarding the route-policy set-cost configuration below, which of the following statements is true?  The route 11.1.0.0/16 is permitted by node 10, and its tost Is set to 300.  The cost of all routes is set to 200.  All the routes that are not permitted by node 10 will be denied.  The route 11.1.0.0/16 will continue to match node 20 after permitted by node 10, and (he final cost is set to 200. Q32. Which of the following statements regarding the stateful inspection firewall is true?  When the stateful inspection firewall checks packets, packets of one same connection are not correlated.  Because UDP is a connectionless protocol, so the stateful inspection firewall cannot match UDP packets with the status table.  The stateful inspection firewall only needs to match the first data packet against a rule, and the subsequent packets of the connection are matched directly in the state table.  The stateful inspection firewall needs to match the rules for each incoming packet. Q33. Which of the following PIM protocol packets have unicast destination addresses.  Register Stop  Bootstrap  Graft  Assert Q34. Which of the following attacks is not the network layer attack?  IP spoofing attack  ICMP attack  Smurf attack  ARP spoofing attack  Loading … ValidBraindumps H12-821_V1.0 Exam Practice Test Questions: https://www.validbraindumps.com/H12-821_V1.0-exam-prep.html --------------------------------------------------- Images: https://free.validbraindumps.com/wp-content/plugins/watu/loading.gif https://free.validbraindumps.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2023-12-12 09:01:30 Post date GMT: 2023-12-12 09:01:30 Post modified date: 2023-12-12 09:01:30 Post modified date GMT: 2023-12-12 09:01:30
