A network planning diagram shows a large internetwork with many routers. The configurations show that OSPF has been enabled on all interfaces, I P addresses correctly configured, and OSPF workinG. For which of the following cases would you expect a router to create and flood a Type 2 LSA?（）
- A、When OSPF is enabled on a LAN interface, and the router is the only router connected to the subnet.
- B、 When OSPF is enabled on a point - to -point serial link, and that router has both the higher router ID and higher interface IP address on the link.
- C、When OSPF is enabled on a Frame Relay point - to - point subinterface, has the lower RID and lower subinterfa ce IP address, and otherwise uses default OSPF configuration on the interface.
- D、When OSPF is enabled on a working LAN interface on a router, and the router has been elected BDR.
- E、None of the other answers is correct.

第6题：
is a method of constructing a project schedule network diagram that uses boxes or rectangles, referred to as nodes, to represent activities and connects them with arrows that show the dependencies.This method includes following types of dependencies or precedence relationships:(67), the initiation of the successor activity, depends upon the completion of the predecessor activity.(68), the initiation of the successor activity, depends upon the initiation of the predecessor activity.
A．PDM
B．CPM
C．PERT
D．AOA
解析：PDM是以一种方块或矩形(或称为节点)来表示活动，并将它们用表示依存关系的箭线连接起来，以构建项目进度网络图的方法。这种方法包括了下列依存或前导关系：完成—开始(F-S)，后续活动的开始依赖于前置活动的完成。开始-开始(S-S)，后续活动的开始依赖于前置活动的启动。
第7题：
Which IOS user EXEC command will allow a network technician to determine which router in the path to an unreachable network host should be examined more closely for the cause of the network failure?
A. EzonexamB> telnet
B. EzonexamB > ping
C. EzonexamB > trace
D. EzonexamB > show ip route
E. EzonexamB > show interface
F. EzonexamB > show cdp neighbors
C 解析：Explanation:
This can perform. the trace command. It sends the ping packets to each of the routers on the way to the receiver. The router which doesn't respond will be a potential failure place in this network.
