The customer’s network connection looks like:HostA—-GE0/0–MSR-1–S1/0—–WAN—–S1/0–MSR-2–GE0/0—-HostBBoth routers are factory default configuration.The four interfaces of the router are configured with correct IP addresses. The two hosts HostA and HostB are configured with IP addresses and gateways. Assuming that all physical connections are normal, then ______. (Multiple choice)  At least one static route needs to be configured on each router to realize the intercommunication between HostA and HostB  At least 2 static routes need to be configured on each router to realize the intercommunication between HostA and HostB  No route is configured on the router, HostA can ping the IP address of interface S1/0 of MSR-2  No route is configured on the router, HostA can ping the IP address of interface S1/0 of MSR-1 Q253. The routing table seen on an MSR router is as follows:Destination/Mask Proto Pre Cost NextHop Interface6.6.6.0/24 Static 60 0 100.1.1.1 GE0/08.8.8.8/32 Direct 0 0 127.0.0.1 InLoop020.1.1.0/24 Static 60 0 100.1.1.1 GE0/030.0.0.0/8 RIP 100 1 100.1.1.1 GE0/0Then the correct analysis of this routing table is ______.  The IP address of GE0/0 on the router is 100.1.1.1  The next hop interface of the route whose destination network segment is 8.8.8.8/32 is InLoop0, indicating that the next hop of the route is a virtual interface similar to Null0, and the route is a black hole route  The router is running RIPv1 because the mask of the destination network segment 30.0.0.0 is a natural mask  The routing table is not the complete routing table of the router, and the complete routing table should have at least the direct network segment route of interface GE0/0 Q254. In the following statement about HDLC, what is wrong is ______. (Multiple choice)  HDLC can run on the same/asynchronous link, so it has a wide range of applications.  The HDLC protocol is a bit-oriented transport layer protocol.  Any bit stream can be transparently transmitted on the HDLC link.  The HDLC protocol uses a unified frame format, so both data messages and protocol messages are transmitted in standard format frames on the HDLC link. Q255. The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)  RSTP is an optimized version of the STP protocol. The delay for the port to enter the forwarding state is greatly shortened under certain conditions, which shortens the time required for the network to finally reach topological stability.  MSTP cannot converge quickly. When the network topology changes, the originally blocked port needs to wait for a period of time before it becomes the forwarding state.  MSTP is compatible with RSTP, but not compatible with STP.  MSTP can make up for the shortcomings of STP and RSTP. It can not only converge quickly, but also enable the traffic of different VLANs to be forwarded along their respective paths, thereby providing a better load sharing mechanism for redundant links. Q256. The FTP protocol is a protocol based on ______.  UDP  TCP  PX  SSH Q257. After configuring the relevant configuration of the Telnet service on the router, the router can be pinged from the PC, but the Telnet router fails, and the PC keeps showing that it is connecting to x.x.x.x. The possible reason is ______. (Multiple choice)  The intermediate network routing configuration is incorrect  The Telnet password is incorrectly set  The router Telnet service is not started  The intermediate network prevents the PC from initiating a connection to the router’s TCP port 23 Q258. On the MSR router, the configuration file is a file saved in ______ format.  Batch file  text file  executable file  database file Q259. On the MSR router, if you want to download files from FTP Server, you should use the ______ command in the FTP command.  get  put  download  load Q260. If a port running STP in the Ethernet switch does not receive or forward data, receives and sends BPDUs, and does not perform address learning, then the port should be in the ______ state.  Blocking  Listening  Learning  Forwarding  Waiting  Disable Q261. Execute the following configuration commands on the router:[Router] dhcp enable[Router] server forbidden-ip 192.168.1.10[Router] server forbidden-ip 192.168.1.254[Router] dhcp server ip-pool 0[Router-dhcp-pool-0] network 192.168.1.0 mask 255.255.255.0[Router-dhcp-pool-0] gateway-list 192.168.1.254[Router-dhcp-pool-0] dns-list 192.168.1.10[Router-dhcp-pool-0] expired day 5After completing the above configuration, which of the following statements are correct? (multiple choice)  The router has a DHCP relay function  There are 252 addresses that the router can assign to the host  The router has a DHCP server function  The host can obtain the DNS server address 192.168.1.10 from the router through the DHCP service Q262. The Layer 2 Ethernet switch searches the MAC address table for an entry that matches the destination MAC address of the frame, thereby forwarding the frame from the corresponding interface. If the search fails, the switch will ______.  discard the frame  Send the frame from all other ports except the incoming port  Find fast forwarding table  Find routing table Q263. The messages exchanged between the DHCP relay and the DHCP server use ______.  unicast  broadcast  multicast  anycast Q264. The basic process of Layer 2 forwarding of an Ethernet switch includes ______.  Add or refresh MAC address table entries according to the source MAC address and VLAN ID information of the received Ethernet frame;  Search the MAC address table according to the destination MAC address, if no match is found, then broadcast in the VLAN corresponding to the message;  If a match is found, but the port corresponding to the entry does not belong to the VLAN corresponding to the packet, then the frame is discarded;  If a match is found and the port corresponding to the entry belongs to the VLAN corresponding to the packet, then the packet is forwarded to that port, but if the port corresponding to the entry is the same as the port that received the Ethernet frame, the packet is discarded. frame Q265. According to the different ways the switch processes VLAN data frames, the port types of H3C Ethernet switches are divided into ______. (Multiple choice)  access port  trunk port  Mirror port  hybrid port  monitor port Q266. In the switching network shown in the figure, all switches have enabled the STP protocol.SWA was selected as the root bridge. According to the information in the figure, the _______ port should be set to the Blocking state. (Multiple choice)  P1 of SWC  P2 of SWC  P1 of SWD  P2 of SWD  Insufficient information, unable to judge Q267. The two routers MSR-1 and MSR-2 are interconnected through the S0/0 interface, and the two routers learn the routes of the LAN segment by running the RIP protocol.See the following configuration commands on MSR-1:[MSR-1-Serial0/0] rip authentication-mode md5 rfc2453 H3CThen the correct interpretation of this command is ______. (Multiple choice)  Configure RIP to use MD5 plaintext authentication  Configure RIP to use MD5 cipher text authentication  Specify the message format specified by RFC2453 for MD5 authentication  Specify the H3C private extended protocol message format for MD5 authentication Q268. The customer’s routers MSR-1 and MSR-2 are interconnected through their GigabitEthernet0/0, and RIP is running between the two routers. RIP has correctly completed remote routing learning. The following configuration is added on MSR-1: firewall enable acl number 3000 rule 0 deny udp destination-port eq 520 rule 5 permit ip and this ACL is applied to the inbound direction of MSR-1 interface GigabitEthernet0/0. So ______ .  MSR-1 still has the RIP route to the opposite end  MSR-1 cannot learn the RIP route of the opposite end  MSR-2 still has the RIP route to the opposite end  MSR-2 cannot learn the RIP route of the opposite end Q269. IPv6 uses ______ notation to represent addresses.  colon hexadecimal  dotted decimal  colon decimal  dotted hexadecimal Q270. The correct statement about STP, RSTP and MSTP is ______. (Multiple choice)  MSTP is compatible with STP and RSTP.  STP cannot converge quickly. When the network topology changes, the originally blocked port will need to wait for a period of time before it becomes the forwarding state.  RSTP is an optimized version of the STP protocol. The delay for the port to enter the forwarding state is greatly shortened under certain conditions, which shortens the time required for the network to finally reach topological stability.  MSTP can make up for the shortcomings of STP and RSTP. It can not only converge quickly, but also enable the traffic of different VLANs to be forwarded along their respective paths, thereby providing a better load sharing mechanism for redundant links.
