A. VLANs have not been created yet.
B. An IP address must be configured for the port.
C. The port is currently configured for access mode.
D. The correct encapsulation type has not been configured.
E. The “no shutdown” command has not been entered for the port.
Correct Answer: C Explanation

Explanation:
According to the output shown the switchport (layer 2 Switching) is enabled and the port is in access mode. To make a trunk link the port should configured as a trunk port, not an access port, by using the 200-125 vce following command: (Config-if)#switchport mode trunk.

QUESTION 5
What is the difference between a CSU/DSU and a modem?

C. A CSU/DSU converts digital signals from a router to a phone line; a modem converts analog signals from a router to a phone line.
D. A CSU/DSU converts digital signals from a router to a leased line; a modem converts digital signals from a router to a phone line.
Correct Answer: D

Explanation:
CSU/DSU is used to convert digital signals from a router to 200-125 a network circuit such as a T1, while a modem is used to convert digital signals over a regular POTS line.
