Protect hosts from viruses.<br>B. Classify network traffic.<br>C. Provide high network availability.<br>D. Identify interesting traffic for DDR.<br>E. IP route filtering.<br>F. Monitor the number of bytes and packets.<br>Answer: C, D, E<br>正确: BDE<br><br><br>这个有点不懂？？我觉得还是原来的答案更好啊。<br>QUESTION NO: 84<br>Which statements is true regarding the command sequence shown below? (Choose three)<br>RouterA(config)# interface loopback 0<br>RouterA(config-if)# ip address 192.168.31.33 255.255.255.255<br>A. It creates a virtual, software only, interface.<br>B. It uses a wildcard mask of 255.255.255.255.<br>C. It ensures that an interface is always active for OSPF processes.<br>D. It provides a way to test the convergence of OSPF routing updates.<br>E. The mask of 255.255.255.255 is called a host mask.<br>F. These commands can only be issued to configure serial interfaces.<br>Answer: A, B, D<br>正确: ACE<br><br>老大，这个的E有点不懂？？<br>QUESTION NO: 121<br>Popcorn# show ip protocols<br>Routing Protocol is “rip”<br>Sending updates every 30 seconds, next due in 13 seconds<br>Invalid after 180 seconds, hold down 180, flushed after 240<br>Outgoing update filter list for all interfaces is<br>Incoming update filter list for all interfaces is<br>Redistribution: rip<br>Default version control: send version 1, receive any version<br>Interface Send Recv Triggered RIP Key-chain<br>Ethernet0 1 12<br>Ethernet1 1 12<br>Serial 1 12<br>Routing for Networks:<br>222.8.4.0<br>10.1.1.0<br>Routing Information Sources:<br>Gateway Distance Last Update<br>222.8.4.1 120 00:00:04<br>An administrator who is consoled into the Peanut router is able to ping the Serial0 and Ethernet0 ports of<br>the Popcorn router but unable to ping its Ethernet1 interface.<br>Use the graphic and command output to identify possible causes for this problem. (Choose two)<br>A. The Serial interface of the Popcorn router is shutdown.<br>B. The Ethernet1 interface of the Popcorn router is shutdown.<br>C. The Popcorn router did not include network 192.168.12.0 in its routing configuration.<br>D. The Popcorn router is not forwarding RIP updates.<br>E. The clockrate is missing from the configuration of one of the routers.<br>Answer: B, C<br>正确: CD<br><br>D从哪看啊？<br>Outgoing update filter list for all interfaces is<br>Incoming update filter list for all interfaces is<br>我觉得D应该是错的？<br>QUESTION NO: 115<br>OSPF routing uses the concept of areas.<br>What are the characteristics of OSPF areas? (Choose three)<br>A. Each OSPF area requires a loopback interface to be configured<br>B. Areas may be assigned any number from 0 to 65535<br>C. Area 0 is called the backbone area<br>D. Hierarchical OSPF networks do not require multiple areas<br>E. Multiple OSPF areas must connect to area 0<br>F. Single area OSPF networks must be configured in area 1<br>Answer: B, C, E<br>正确: CDE<br><br> D有点不解？？<br>还有这题？？QUESTION NO: 145<br>RtrB#show interface serial0/0<br>Serial0/0 is up, line protocol is up<br>Hardware is PowerQUICC Serial<br>Internet address is 10.0.15.2/21<br>MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec,<br>reliability 255/255, txload 1/255, rxload 1/255<br>Encapsulation PPP, loopback not set<br>Keepalive set (10 sec)<br>LCP Open<br>Closed: IPXCP<br>Listen: CCP<br>Open: IPCP, CDPCP<br>Last input 00:00:00, output 00:00:00, output hang never<br>Last clearing of "show interface" counters 00:52:02<br>Input queue: 0/75/0/0 (size/max/drops/flushes): total output drops: 0<br>Queuing strategy: weighted fair<br>Output queue: 0/1000/64/0 (size/max total/threshold/drops)<br>After reviewing the command output, which of the following are operational on the serial link? (Choose<br>two)<br>A. IPX<br>B. IP<br>C. Compression<br>D. CDP<br>E. Multilink<br>Answer: C, E<br>正确: BD<br><br>真的看不懂？？还是觉得原来的对。<br><br> 见小熊的帖子，请小熊和化辉联系，告知这些题目的正确答案。
