Refer to the exhibit. Which two statements are true about interVLAN routing in the topology that is
shown in the exhibit? (Choose two.)
A. Host E and host F use the same IP gateway address.
B. Router1 and Switch2 should be connected via a crossover cable.
C. Router1 will not play a role in communications between host A and host D.
D. The FastEthernet 0/0 interface on Router1 must be configured with subinterfaces.
E. Router1 needs more LAN interfaces to accommodate the VLANs that are shown in the exhibit.
F. The FastEthernet 0/0 interface on Router1 and Switch2 trunk ports must be configured using
the same encapsulation type.
Refer to the exhibit. Which two statements are true about the loopback address that is configured
on RouterB? (Choose two.)
A. It ensures that data will be forwarded by RouterB.
B. It provides stability for the OSPF process on RouterB.
C. It specifies that the router ID for RouterB should be 10.0.0.1.
D. It decreases the metric for routes that are advertised from RouterB.
E. It indicates that RouterB should be elected the DR for the LAN.
If you are a network administrator, how will you explain VTP configuration to a new technician?
A. In the VTP client mode, a switch is unable to update its local VLAN database.
B. Configure a trunk link between the switches to forward VTP updates.
C. In the VTP server mode, a switch is able to update a switch in the VTP transparent mode.
D. In the VTP transparent mode, a switch will forward the received updates to other switches.
E. A switch in the VTP server mode only updates switches in the VTP client mode that have a
higher VTP revision number.
F. A switch in the VTP server mode will update switches in the VTP client mode regardless of the
configured VTP domain membership.
VTP operates in one of three modes:
Server – In this VTP mode you can create, remove, and modify VLANs. You can also set other
configuration options like the VTP version and also turn on/off VTP pruning for the entire VTP
domain. VTP servers advertise their VLAN configuration to other switches in the same VTP
domain and synchronize their VLAN configuration with other switches based on messages
received over trunk links. VTP server is the default mode. The VLANs information are stored on
NVRAM and they are not lost after a reboot.
Client – VTP clients behave the same way as VTP servers, but you cannot create, change, or
delete VLANs on the local device. In VTP client mode, VLAN configurations are not saved in
Cisco IOS (originally Internetwork Operating System) is the software used on the vast majority of
Cisco Systems routers and all current Cisco network switches. Which two of the following devices

C. flash memory
D. HTTP server
E. TFTP server
F. Telnet server
