There are three routers on a Gigabit Ethernet LAN: Router A,

There are three routers on a Gigabit Ethernet LAN: Router A, Router B, and Router C. Router A is the Designated Intermediate System (DIS) at Level 1 for that LAN. Router A‘s DIS priority is 64. The LAN is a Level 1-only link. Router D has just been powered up on that same LAN and its DIS priority is 80.Which statement is true?（）

A. Router A remains the DIS and generates a new pseudonode LSP for that LAN

B. Router A remains the DIS and NO new pseudonode LSP is generated for that LAN

C. Router D becomes the new DIS, generates a new pseudonode LSP for that LAN, and purges the old pseudonode LSP generated by Router A

D. Router D becomes the new DIS, does NOT generate a new pseudonode LSP for that LAN, and does NOT purge the old pseudonode LSP generated by Router A

DR (Designated Router) is for environments where many routers on the same network such as Ethernet. In the following presented network, all routers are reloaded simultaneously, and DR is selected as expected. What is the RTC status?（）

A. 2WAY/DR

B. FULL/DR

C. FULL/DROTHER

D. FULL/BDR

You are trying to connect directly into the LAN prot of a Ezonexam router. You want to telnet to the local Cisco router using TCP/IP but cannot create a session.

What should you do to resolve the problem?

A. Use a straight-through cable to connect your computer's COM port to the router's console port.

B. Use a crossover cable to connect your computer's COM port to the router's console port.

C. Use a straight-through cable to connect your computer's COM port to the router's Ethernet port.

D. Use a crossover cable to connect your computer's Ethernet port to the router's Ethernet port.

E. Use a rollover cable to connect your computer's Ethernet port to the router's Ethernet port.

F. Use a straight-through cable to connect your computer's Ethernet port to the router's Ethernet port.

G. None of the above

The OSPF process has been started and the networks have been configured for Area 0 as shown in the diagram. The network administrator has several options for configuring RouterB to ensure that it will be preferred as the designated router (DR) for the 172.16.1.0 /24 LAN segment. What configuration tasks could be used to establish this preference (Choose three.)（）。

A.Configure the priority value of the Fa0/0 interface of RouterB to a higher value than any other interface on the Ethernet network.

B.Change the router id of Router B by assigning the IP address 172.16.1.130/24 to the Fa0/0 interface of RouterB.

C.Configure a loopback interface on RouterB with an IP address higher than any IP address on the other routers.

D.Change the priority value of the Fa0/0 interface of RouterB to zero.

E.Change the priority values of the Fa0/0 interfaces of RouterA and RouterC to zero.

F.No further configuration is necessary.

A. Dev - 1 is the DR because it has a lower OSPF router ID

B. Dev - 3 is the DR because it has a higher OSPF router priority

C. Both Dev - 1 and Dev - 3 are using the def ault OSPF router priority

D. Dev - 3 is the DR because it has a lower OSPF router ID

E. Dev - 1 is the DR because it has a higher OSPF router priority
