问一下CCNA的题

这道也看一下,CHINAITLAB上众说纷纭,有的说是E.<br><br><br>QUESTION NO: 1<br>You work as network administrator at TestKing.<br>Your trainee is configuring a router with both physical and logical interfaces.<br>He asks you what factor determines the OSPF router ID.<br>What should you tell him?<br>A. The lowest network number of any interface.<br>B. The lowest IP address of any logical interface.<br>C. The lowest IP address of any physical interface.<br>D. The highest network number of any interface.<br>E. The highest IP address of any logical interface.<br>F. The highest IP address of any physical interface.<br><br><br>Answer: F<br>Explanation:<br>The OSPF topology database includes information about routers and the subnets, or links, to which they are<br>attached. To identify the routers in the neighbor table’s topology database, OSPF uses a router ID (RID) for<br>each router. A router’s OSPF RID is that router’s highest IP address on a physical interface when OSPF starts<br>running.<br>Note: The OSPF router ID is a 32-bit IP address selected at the beginning of the OSPF process. The highest IP<br>address configured on the router is the router ID. If a loopback address is configured, then it is the router ID. In<br>case of multiple loopback addresses, the highest loopback address is the router ID. Once the router ID is elected<br>it doesn&#39;t change unless the IP address is removed or OSPF restarts.

呵呵，版主说话越来越有气质了。：）<br>小熊，你还有5小时的练习实验时间，不妨到学校来上机试试？这些命令一试便知！<br><br>

原文由 [B]cwav[/B] 发表:<br>还有些关于ISDN的题我也不会<br><br>有不懂的大胆地提，兄弟们支持你～不过……千万不要全部不懂……这样的话……呵呵，请参见XXXX一书……<br>Which command is used to display the placement and direction of an IP access control list on a router?<br>A. show access-list  查看访问列表的内容<br>B. show ip route 查看路由表<br>C. show ip interface 查看访问列表的应用情况<br>D. show interface 查看接口的信息<br>E. show interface list 好像无此命令？！<br>F. show ip interface brief 查看接口概要信息<br><br>这些命令去机器上试一试就应该都知道了～：）祝考试成功<br>
