[*] The OSPF area is not configured properly． The priority on R1 should be set higher． The cost on R1 should be set higher． The hello and dead timers are not configured properly． A backup designated router needs to be added to the network．

Refer to the exhibit． Which two statements are true about interVLAN routing in the topology that is shown in the exhibit? [*] Host E and host F use the same IP gateway address． Router1 and Switch2 should be connected via a crossover cable． Router1 will not play a role in communications between host A and host D． The FastEthernet 0/0 interface on Router1 must be configured with subinterfaces． The FastEthernet 0/0 interface on Router1 and Switch2 trunk ports must be configured using the same encapsulation type．

What three pieces of information can be used in an extended access list to filter traffic? protocol VLAN number TCP or UDP port numbers source switch port number source IP address and destination IP address

Refer to the exhibit． Hosts on the same VLAN can communicate with each other but are unable to communicate with hosts on different VLANs． What is needed to allow communication between VLANs? [*] a switch with a trunk link that is configured between the switches a router with an IP address on the physical interface that is connected to the switch a switch with an access link that is configured between the switches a router with subinterfaces configured on the physical interface that is connected to the switch

Which statement accurately describes a benefit provided by VTP? VTP allows routing between VLANs． VTP allows a single port to carry information to more than one VLAN． VTP allows physically redundant links while preventing switching loops． VTP allows switches to share VLAN configuration information．

What does the “Inside Global“ address represent in the configuration of NAT? the summarized address for all of the internal subnetted addresses the MAC address of the router used by inside hosts to connect to the Internet a globally unique, private IP address assigned to a host on the inside network a registered address that represents an inside host to an outside network

Refer to the exhibit． S0/0 on R1 is configured as a multipoint interface to communicate with R2 and R3 in this hub-and-spoke Frame Relay topology． While testing this configuration, a technician notes that pings are successful from hosts on the 172．16．1．0/24 network to hosts on both the 172．16．2．0/25 and 172．16．2．128/25 networks． However, pings between hosts on the 172．16．2．0/25 and 172．16．2．128/25 networks are not successful． What could explain this connectivity problem? [*] The ip subnet-zero command has been issued on the R1 router． The RIP v2 dynamic routing protocol cannot be used across a Frame Relay network． Split horizon is preventing R2 from learning about the R3 networks and R3 from learning about the R2 networks． The 172．16．2．0/25 and 172．16．2．128/25 networks are ov erlapping networks that can be seen by R1, but not between R2 and R3． The 172．16．3．0/29 network used on the Frame Relay links is creating a discontiguous network between the R2 and R3 router subnetworks．
