When Mr. Wang unpacked and inspected the goods, he found that the appearance of the equipment was not damaged, and all the modules of the equipment were running normally when the power was first turned on, but after 24 hours of continuous operation, the board failed, then this situation is not eligible for the DOA process.  TRUE  FALSE Q165. The network administrator A wants to use the AS-Path Fiter to match the routing entries of the BGP routing attribute AS_PATH[100 200 300]. The network administrator A sorts out the four configurations in the figure. Which of the following configurations can satisfy the network administrator A’s requirements? (Multiple choice)  Method C  Method A  Method D  Method B Q166. A campus deploys both IPv4 and IPv6 networks for service testing, and runs IS-IS to achieve network interconnection. The IS-IS routing protocol has good scalability and is widely used in the existing network. Which of the following statements is true about IS-IS scalability? (Multiple choice)  IS-IS uses the TLV structure to construct packets, making IS-IS more flexible and extensible  For IS-IS, adding new features only needs to add new TLVs  IS-IS needs to add TLV to carry IPv6 address information in order to support IPv6  NLPID is a new TLV added by IS-IS to support IPv6 Q167. Which of the following statements about the OSPFv3 packet format is correct? (Multiple choice)  Hello packets no longer contain address information to carry Interface ID  OSPF version number changed from 2 to 3  Removed Authentication, Auth Type fields  There is no change in the option field of the Hello message Q168. In the label forwarding table of the MPLS device, for different routes (the next hop is also different), the label is sent out:  must be different  must be the same  may be the same Q169. Regarding multi-instance MCE (Mlulti-VPN-Instance CE, MCE), which of the following descriptions is wrong?  On the MCE device, you need to create their own routing and forwarding tables for different VPNs and bind them to the correct interface  Users who are connected to the same MCE but do not belong to a VPN instance cannot access each other  Devices with MCE function can access multiple VPN instances in BGP MPLS IP VPN applications, reducing the investment in user network equipment  There must be multiple physical links between MCE and PE to achieve isolation between different VPIN instances Q170. When upgrading equipment software, it is necessary to make adequate preparations, and formulate upgrade plans and rollback plans.  True  False Q171. In addition to the virtual connection, what type of IPv6 address is the source IPv6 address of the Hello packet of OSPFv3?  IPv6 anycast address  Unique local address  Global Unicast Address  Link-local address Q172. Network administrator A wants to use the IP Prefix List to match a specific route entry. Which of the following routes will be matched by the IP Prefix List in the figure? (Multiple choice)  10.0.0.1/30  10.0.0.0/24  10.0.2.0/24  10.0.1.0/24 Q173. Which statement about DHCP Snooping is wrong?  DHCP Snooping can prevent illegal attacks by setting trusted ports (all interfaces are untrusted by default)  Enable the DHCP snooping function globally, and the device only processes DHCPv4 packets by default without any post-parameters  When the DHCP snooping function is enabled in the interface view, all DHCP packet commands on the interface will take effect.  When the DHCP snooping function is enabled in the VLAN view, the command function will take effect on the DHCP packets received by all the interfaces of the device belonging to the VLAN. Q174. What are the working modes of firewall interfaces? (Multiple choice)  Exchange Mode  Transparent Mode  Transmission Mode  Routing Mode Q175. Among the following options, which of the following descriptions is wrong?  LSP established by statically assigning labels can also be dynamically adjusted according to network topology changes without administrator intervention  The principle to be followed when manually assigning labels is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node  LSP are classified into static LSP and dynamic LSP. Static LSP are manually configured by administrators, and dynamic LSP are dynamically established using label protocols.  Dynamic LSPs are dynamically established through label distribution protocols such as MP-BGP Q176. Which LSAs in OSPFv3 can be flooded within an area? (Multiple choice)  Link-LSA  Inter-Area-Router-LSA  Inter-Area-Prefix-LSA  Intra-Area-Prefix-LSA Q177. Regarding MP-BGP, which of the following descriptions is wrong?  When the PE and CE exchange routes through BGP, a BGP process needs to be created on the CE for each VPN instance  MP-BGP’s packet types and VPNv4 route advertisement policies are the same as BGP-4  MP-BGP needs to assign private network labels to VPNV4 routes  MP-BGP advertises VPNv4 routes through MP REACH NLRI and MP UREACH NLRI attributes Q178. In what ways can log information be viewed? (Multiple choice)  View the network management system interface  Log in to the device and view it through display logbufer  There is no way  will flash Q179. Display interface GE0/0/0 once and find that the Total Error count (the total number of error packets at the physical layer of the interface) is not 0. At this time, it can be concluded that the current time error has not disappeared.  True  False Q180. Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors. Deploying routing policies between IBGP neighbors is invalid.  True  False Q181. Which of the following statements about ASPF and Servermap is true? (Multiple choice)  ASPF checks application layer protocol information and monitors the application layer protocol status of the connection  ASPF determines whether packets pass through the firewall by dynamically generating ACLs  Configure NAT Server to generate static Server-map  The Servermap table uses a five-tuple to represent a conversation Q182. Please match the OSPFv3LSA with its delivery range. Q183. View the running configuration in memory through display current-configuration.  TRUE  FALSE Q184. Regarding the description of OSPF’s neighbor relationship failure, which of the following statements is false?  Stalling in ExStart state may be due to MTU mismatch between neighboring routers  Stalling in the lnit state indicates that the router has received the neighbor’s Hello packet, but the Hello packet does not contain the OSPF Router ID of the router  The two router databases are synchronized, and an error occurs in the SPF calculation. It must be because the router ID is duplicated  For a pair of DR Others on an Ethernet link Q185. RR rules for advertising routes violate the rules of IBGP split horizon, so it may cause loops in the AS. What routing attributes does RR use to prevent loops? (Multiple choice)  Cluster List  Originator ID  Nexthop  AS-PATH Q186. There are different ways of MPLS encapsulation. Which of the following statements are correct about the encapsulation method?(Multiple choice)  ATM uses cell mode encapsulation  Ethernet and PPP use frame mode encapsulation  When encapsulating in cell mode, if the MPLS Header has been deactivated in the packet  MPLS encapsulation has frame mode and cell mode  Loading … View All H12-831-ENU Actual Free Exam Questions Updated: https://www.validexam.com/H12-831-ENU-latest-dumps.html --------------------------------------------------- Images: https://premium.validexam.com/wp-content/plugins/watu/loading.gif https://premium.validexam.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-12-19 16:13:36 Post date GMT: 2022-12-19 16:13:36 Post modified date: 2022-12-19 16:13:36 Post modified date GMT: 2022-12-19 16:13:36
