Refer to the exhibit． The networks connected to router R2 have been summarized as a 192．168．176．0/21 route and sent to R1． Which two packet destination addresses will R1 forward to R2? [*] 192．168．194．160 192．168．183．41 192．168．159．2 192．168．183．255 192．168．179．4

Refer to the exhibit． Switch-1 needs to send data to a host with a MAC address of 00b0．d056．efa4． What will Switch-1 do with this data? [*] Switch-1 will drop the data because it does not have an entry for that MAC address． Switch-1 will flood the data out all of its ports except the port from which the data originated． Switch-1 will send an ARP request out all its ports except the port from which the data originated． Switch-1 will forward the data to its default gateway．

Refer to the output from the show running-config command in the exhibit． What should the administrator do to allow the workstations connected to the FastEthernet 0/0 interface to obtain an IP address? [*] Apply access-group 14 to interface FastEthernet 0/0． Add access-list 14 permit any any to the access list configuration． Configure the IP address of the FastEtherent 0/0 interface to 10．90．201．1． Add an interface description to the FastEthernet 0/0 interface configuration．

On point-to-point networks, OSPF hello packets are addressed to which address? 127．0．0．1 172．16．0．1 192．168．0．5 223．0．0．1 224．0．0．5

In order to allow the establishment of a Telnet session with a router, which set of commands must be configured? router(config)# line console 0 router(config-line)# enable password cisco router(config)# line console 0 router(config-line)# enable secret cisco router(config-line)# login router(config)# line console 0 router(config-line)# password cisco router(config-line)# login router(config)# line vty 0 router(config-line)# enable password cisco router(config)# line vty 0 router(config-line)# password cisco router(config-line)# login

In the implementation of VLSM techniques on a network using a single Class C IP address, which subnet mask is the most efficient for point-to-point serial links? 255．255．255．0 255．255．255．240 255．255．255．248 255．255．255．252 255．255．255．254

Refer to the exhibit． The network shown in the exhibit is running the RIPv2 routing protocol． The network has converged, and the routers in this network are functioning properly． The FastEthernet0/0 interface on R1 goes down． In which two ways will the routers in this network respond to this change? [*] All routers will reference their topology database to determine if any backup routes to the 192．168．1．0 network are known． Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire． Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192．168．1．0 network． When router R2 learns from R1 that the link to the 192．168．1．0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192．168．1．0 network． R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges．
