B. The IP address 10.121.16.8 is the local router port used to forward data.
C. 102 is the remote DLCI that will receive the information.
D. This command is required for all Frame Relay configurations.
E. The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC.
解释一下:关于命令frame-relay map ip 10.121.16.8 102 broadcast ,这个命令用于手工静态添加一条映射,到达10.121.16.8的流量封装一个DLCI号为102,而且这条PVC是支持广播的流量的,比如RIP的更新包。因为在默认的情况下,帧中继的网络为非广播的,而RIP在其上是无法发包的。
8.Which of the following are associated with the application layer of the OSI model? (Choose two.)
解释一下:在OSI 7层模型中位于应用层的应用有telnet 和ftp 这两种应用。
9. For security reasons, the network istrator needs to prevent pings into the corporate networks from hosts outside the internetwork. Which protocol should be blocked with access control lists?
10.Refer to the exhibit. The network istrator has created a new VLAN on Switch1 and added host C and host D. The istrator has properly configured switch interfaces FastEthernet0/13 through FastEthernet0/24 to be members of the new VLAN. However, after the network istrator completed the configuration, host A could communicate with host B, but host A could not communicate with host C or host D. Which commands are required to resolve this problem?
