IP addresses and routing for the network are configured as shown in the exhibit． The network administrator issues the show ip eigrp neighbors command from Router1 and receives the output shown below the topology． Which statement is true? [*] It is normal for Router1 to show one active neighbor at a time to prevent routing loops． Routing is not completely configured on Router3． The IP addresses are not configured properly on the Router1 and Router3 interfaces． The no auto-summary command configured on the routers prevents Router1 and Router2 from forming a neighbor relationship．

A network administrator is configuring the routers in the graphic for OSPF． 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? [*] Configure the priority value of the Fa0/0 interface of RouterB to a higher value than any other interface on the Ethernet network． Change the router id of Router B by assigning the IP address 172．16．1．130/24 to the Fa0/0 interface of Router B． Configure a loopback interface on RouterB with an IP address higher than any IP address on the other routers． Change the priority value of the Fa0/0 interface of RouterB to zero． Change the priority values of the Fa0/0 interfaces of RouterA and RouterC to zero．

Refer to the exhibit． A problem with network connectivity has been observed． It is suspected that the cable connected to switch port Fa0/9 on Switch1 is disconnected． What would be an effect of this cable being disconnected? [*] Host B would not be able to access the server in VLAN9 until the cable is reconnected． Communication between VLAN3 and the other VLANs would be disabled． The transfer of files from Host B to the server in VLAN9 would be significantly slower． For less than a minute, Host B would not be able to access the server in VLAN9． Then normal network function would resume．

Refer to the output of the two show commands in the exhibit． If an administrator tries to ping host 10．1．8．5 from host 10．1．6．100, how will the ICMP packets be processed by Router A?
