A switch is operating in VTP client mode. What is true about the operations that can be performed by the switch?
VLANs that are created are not included in advertisements.
It can only adopt VLAN changes advertised from a VTP server.
It advertises topology changes out all trunk ports.
It can modify existing VLANs, but can not create new ones.
It can create and modify VLANs, but can not delete existing ones.
4
Why would a network administrator choose to enable authentication for OSPF exchanges? (Choose two.)
to prevent routing information from being falsified
to reduce OSPF information exchange overhead
to assure that OSPF routing information takes priority over RIP or IGRP updates
to encrypt routing tables to prevent unauthorized viewing
to ensure that routing information comes from a valid source
5
A network administrator asked an assistant to remove several VLANs from a switch. When the assistant entered in the no vlan 1 command an error was received. What was the cause of the error?
VLANs can not be deleted until all ports have been removed from the VLAN assignment.
VLANs can only be deleted by the user that created them.
VLAN 1 can not be deleted until another VLAN has been assigned its duties.
VLAN1 is the management VLAN by default and can not be deleted.
The command was not entered properly, which caused a syntax error to occur.

Which of the following statements is true when VTP is configured on a switched network that incorporates VLANs?
VTP is only compatible with the 802.1Q standard.

Changes made to the network can be communicated to all switches dynamically.
9
Which of the following tasks must be completed to configure a router interface to serve the newly added network 192.168.10.64/27 and to advertise this network over RIP v2? (Choose three.)
RIP v2 must be configured with the network command and the IP network number for the new network.
RIP v2 must be configured with the network command and the IP host address and subnet mask for the newly activated interface.
The router must be configured with the ip subnet-zero command so that this network can be added and advertised.
A network host address and subnet mask must be applied to the newly activated interface.
The routing protocol must be activated with the router rip and version 2 commands.
RIP v2 must be configured on the other enterprise routers with an entry for the newly added network.
