( 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 325BGP routing policies can control the publication and acceptance of routes  TRUE  FLASE QUESTION 326What’s wrong about vrrp timers is ?  MASTER DOWN = (3*ADVER_ INTERVAL) + Skew_ time  Skew Time= (255-Priority)/255  By default, the time period for VRRP advertisement messages is 2 seconds  By default, the VRRP preemption delay is I seconds QUESTION 327Regarding the sliding window of TCP, what are the following descriptions that are enough to be wrong? ( Multiple choice question)  The sender declares the initial window size  The sender does not need to transmit messages of full window size  The TCP sliding window allows multiple packets to be sent before an acknowledgment is received  After the retransmission timer times out, the sender has not received an acknowledgment and will retransmit unacknowledged data  The receiver needs to acknowledge the sender’s packet  Sliding window size can only be increased or remain unchanged QUESTION 328The RSTP protocol provides a variety of protection functions, such as when the edge port is configured as a protection state, the edge port receives the BPDU packet processing method;  Directly discard the BPDU packet  Close the port  After parsing the BPDU message, the relevant information is obtained  Forward BPDU packets as required QUESTION 329Level-1-2IS transmits Level-2LSP to the Level-1 area if the AT location 1 in Level-2LSP is delivered It means that the Level-1lS in the area can be accessed to the outer area through Level-1-2IlS  True  False QUESTION 330What 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 QUESTION 331The 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 QUESTION 332The following about the Router-LSA of OSPFv3 is correct?( Single choice questions).  The router-LSA data area contains the Link-Local address  The router-LSA data area contains the Interface ID of the neighbor on this side  Similar to OSPFv2, the Option field exists in the header of LSA, not in the data area of Router-LSA  When LS type= Ox0001 in the head of LSA, the data area representing LSA is Router-LSA QUESTION 333Regarding the description of the hello message in the PIM-SM message, the error is ?  Hello messages are sent to multicast address 224005  Elect dr in multiple router segments with hello messages  Routers periodically use hello messages to stay in touch  In a PIM-SM network, a newly started multicast router needs to use hello messages to discover neighbors and maintain neighbor relationships QUESTION 334When there are multiple redundant links in an IS-IS network, multiple equivalent routes may occur. Regarding equivalent routing within an IS-IS network, which of the following descriptions is wrong?  When the number of equivalent routes present in the networking is greater than the number configured by the command, and these routes have the same priority, the next hop device System IlD large routes are preferred for load sharing  After you configure the equivalent routing priority, when the IS-S device forwards traffic to the destination segment, it will not use load sharing, but forward the traffic to the next hop with the highest priority  For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes  If load sharing is configured, traffic is evenly distributed across each link QUESTION 335The 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 QUESTION 336All interfaces of the router have OSPF enabled, the Cost value of the link is identified in the figure, and the Loopback0 socket for R2 is advertised in area 1 , then Rl reaches 10022/32 with a Cost value of ?  50  150  200  100 QUESTION 337What is the correct description of the scene shown in the following figure?  R1 simultaneously exists level-1 and Level-2 LSDB  R1 can ping the interface address of R2 loopback 0  R1 has a route to R2 loopback 010022/32  There is no neighbor relationship between R1 and R2 QUESTION 338Regarding the Stub region and the NSSA region of the OSPF protocol , the following statement is incorrect with a single choice  Neither the Stub region nor the NSSA region allows injection of Type4 LSA  Type5 LSA injection is not allowed in the Stub region, while Type5LSA injection is allowed in the NSSA region  Type7LSA injection is not allowed in the Stub region, while Type7LSA injection is allowed in the NSSA region  Both the Stub region and the NSSA region allow injection of Type3 LSA QUESTION 339/R1Jospf1lRL-osp- jarea.2[RLospf-1-arca-0002]network1001310000 As shown in the configuration, the administrator configured OSPF but RI on R1 You cannot learn routes for other routing rings. Then the possible cause is the question).  This router does not have an OSPF process number configured  This router is configured with a different zone ID than its neighbor router’s zone ID  This router does not have authentication features configured, but neighbor routers configure authentication features  The declared network address of this router does not match the interface mask QUESTION 340BGP authentication can prevent illegal routers from establishing neighbors with BGP routers, BGP authentication can be divided into MD5 authentication and Keychain authentication, please ask which BGP messages will be carried below BGPKeychain authentication information?( Multiple select).  Update  Notification  Keeplive  Open QUESTION 341The correct description about the prefix list is:  The prefix list is used to filter P prefixes and can match both prefix numbers and prefix lengths  The prefix list is used to filter IP prefixes, and cannot match both the prefix number and the prefix length  The prefix list cannot be used for packet filtering  The prefix list can be used to filter packets QUESTION 342Regarding route Policy, the following description is correct as ?( Multiple selection) Multiple selection  Advanced ACLs can be applied in route-policy to filter routes  The table entry exceed::0 less-equal 128 indicates that all IPv6 routes are allowed through  If more than one node is defined in Route-policy, at least one node in each node should have a matching pattern of permit  Route-Policy can filter only the default route QUESTION 343As 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 QUESTION 344What improvements have been made to the IGMPv2 protocol compared to IGMPv1? ( Multiple Choice)  Added maximum response time field  Added high group messages  Added specific group query message  Added a specific source group query packet QUESTION 345IPV6 multicast introduces the concept of multicast scope, which of the following ways is the multicast scope concept implemented? Multi-select  When the group shake source sends IP6 multicast data, the TTL value of the packet is set to limit the transmission range of the group shake  There is a special field in the IPv6 multicast address that specifies the propagation range of multicast.  Multicast scope is just a concept of spreading scope, and there is no specific technical implementation.  During network configuration, the administrator uses the configuration command at the edge of the network to limit the multicast scope. QUESTION 346The following description of the BGP route reflector is ?( Multiple choice questions).  Cluster_List is an optional non-staging property for ring protection within the cluster.  The route learned from the client, all non-clients and clients published to this RR.  A network of bones is divided into multiple reflection clusters, each of which configures the other RRs as non-clients, and establishes an IBGP full connection between the RRs.  The Originator_ID attribute is generated by the Route Reflector (RR) for inter-cluster ring protection.  Loading … H12-891_V1.0 Free Sample Questions to Practice One Year Update: https://www.dumpsmaterials.com/H12-891_V1.0-real-torrent.html --------------------------------------------------- Images: https://exams.dumpsmaterials.com/wp-content/plugins/watu/loading.gif https://exams.dumpsmaterials.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2023-01-10 16:39:30 Post date GMT: 2023-01-10 16:39:30 Post modified date: 2023-01-10 16:39:30 Post modified date GMT: 2023-01-10 16:39:30
