Q: What are two functions that occur at the Internet layer of the TCP/IP model? (Choose two.)
establishment of logical connections between source and destination hosts
A: end-to-end flow control
determination of best paths through the network

Q: A high-end Catalyst switch that supports both ISL and 802.1Q is to be connected by a link that will carry all VLAN traffic to a Catalyst 2960 LAN switch. What two commands are required to configure an interface on the high-end Catalyst switch to carry traffic from all VLANs to the Catalyst 2960 switch? (Choose two.)
Switch(config-if)# vlan all
Switch(config-if)# switchport access vlan 30
Switch(config-if)# switchport access vlan all
A: Switch(config-if)# switchport mode trunk
A: Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport trunk encapsulation isl

I: A network administrator is configuring a switch when an error message appears. The configuration commands and error message appear as follows:
Switch(config)# interface fastethernet 0/1
Switch(config-if)# switchport mode trunk
I: Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode.
Q: What is the problem?
The switch port is configured as an access mode port.
The switch port does not support trunking on this port.
A: The encapsulation type must be changed to a compatible protocol before the port can be placed in trunk mode.
The no switchport trunk encapsulation auto command needs to be applied to the switch port before trunking can be enabled.

Q: Of the protocols that are listed, which one needs to be functioning on a link in order for VTP to operate?
A: 802.1Q
CDP
RIP
RSTP

Q: Which three STP states were replaced with the RSTP discarding state? (Choose three.)
A: listening
learning
blocking
A: disabled
A: forwarding

Q:The ISP of the XYZ Company is moving to IPv6 but XYZ wants to continue to use only IPv4 for another year. Which IPv4-to-IPv6 transition method would allow the company to continue using only IPv4 addresses?
dual stack
6to4 tunnel
manual tunneling
A: NAT-PT

Q: What is associated with link-state routing protocols?
low processor overhead
poison reverse
routing loops
split horizon
A: shortest-path first calculations

Q: Which router command will verify that the router has a path to a destination network?
Router# show ip interfaces brief
A: Router# show ip route
Router# show cdp neighbors
Router# show running-config
Router# show protocols

Q: After several configuration changes are made to a router, the copy running-configuration startup-configuration command is issued. Where will the changes be stored?
flash
ROM
A: NVRAM
RAM
the configuration register
a TFTP server
