Media Access Control (MAC) is part of which OSI layer?
Data Link
What standard covers Ethernet protocols?
802.3
What would be the result of having a device on the network that is receiving data faster than it can handle, and how could it be prevented?
Bottle-neck and traffic shaping
What is a disadvantage of the OSI network model?
Complex to set-up and manage
What is a disadvantage of using the OSPF protocol?
Processor intensive - demands a lot of the computer
What is an advantage of using the OSPF protocol?
Low link overhead
What is an advantage of the TCP/IP network model?

What is true of traffic shaping?
Buffers excess traffic
An ISP (internet service provider) wants to differentiate customer packages by connection speed. Which method would achieve this?
Bandwidth throttling
What network failure would be considered to be caused by human error?
Changes to configuration files
What is true for using checksums when transmitting data?
Allows correction of errors
Why does contention in a network cause a slow response for users?
Data has to be retransmitted
What is the correct method used to stop users streaming content and affecting network performance?
Implementing network policies
In what scenario would it be preferable to use static routing?
Where network resilience is a priority
Name an advantage of using static routing?
Low processor overhead
Define dynamic routing?
A network technique where routers select paths according to real-time changes
Name a difference between dynamic and static routing?
Dynamic routing is harder to configure
An organisation wants to prioritise the traffic from selected sources, which of the following enables this?
