Assignment Background Information
After evaluating and completing support for high-definition IP cameras to enhance security for DeVry University, you have completed a design of the network switching infrastructure that fully supports both the existing data traffic and the additional HD camera traffic, according to requirements. Last week, you discussed your template of configurations with the network manager.
Over the past couple of months, the university has experienced a number of issues with Layer 2 loops and the loss of VLANs. We discovered that a student connected a switch that was purchased at a local garage sale to the network and inadvertently bridged the network, causing a Layer 2 loop. The switch also wiped out the VLANs on the upstream switches. Be sure to describe how your implementation will prevent this type of problem in the future.
Your manager is concerned with the network's inability to self-heal when experiencing these types of network issues. As the network engineer, he has asked you to do a network assessment on the network's health and how to prepare the network for any future STP and VTP issues.

a. VTP version
b. VTP authentication scheme
c. VTP pruning
b. Transparent
c. VTP trunking protocol
a. 802.1dq(dot1q)
b. ISL
