<br>没有BRI接口的设备也属于TE2

小熊

我知道了NT1<br>然后搭车问,NT2的作用是什么?

◎◎没有什么作用阿，只是设备类型不同而已，最后还都不是为了能够进行拨号嘛～NT2用S/T接口，NT1用U接口……

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>这题不懂？？

那个id不是自己定的吗？为什么与ip有关啊？

You work as a network technician at TestKing. You have subnetted the 201.105.13.0 network with a /26<br>mask. Your boss asks you how many usable subnetworks and usable host addresses per subnet this will<br>provide. What should you tell her?<br>A. 64 networks and 4 hosts<br>B. 4 networks and 64 hosts<br>C. 2 networks and 62 hosts<br>D. 62 networks and 2 hosts<br>Answer: C<br>我觉得它应该还有两个networks

<br>OSPF的RD选择问题，选取最高的IP，通常可以设置一个loopback地址

<br><br>TCP/IP（好像也叫DOD？）分为4层，应用层对应OSI上面三层。传输层相同。互联层对应OSI网络层，然后就是主机链路层对应OSI下面两层。去看看资料，会清晰一些
