Which of the following statements about CPU throttling are true ?
Each correct answer represents a complete solution. Choose two.

A.
It is a process of cutting down the CPU processing time for an application, which is
malfunctioning.

B.
It is the process of running a computer component, such as CPU, at a higher clock rate than
specified by the component manuurer.

C.
It prevents applications using more than a certain percentage of CPU time in a certain time
frame.

D.
It is a method for minimizing performance bottlenecks and reducing network traffic by serving
locally cached Web content.

Explanation:

CPU throttling is a process of cutting down the CPU processing time for an application, which is
malfunctioning. For example, if a Terminal Server user opens an application that uses 100% of the
CPU time, the whole server becomes unresponsive, and other logged in users on the Terminal Server
experience a slow performance, then CPU throttling is needed for freeing up CPU time and making
the server performance better. In this situation, CPU throttling prevents applications using more
than a certain percentage of CPU time in a certain time frame. It provides users a better Server
Based Computing experience.

Answer option D is incorrect. Web caching is a method for minimizing performance bottlenecks and
reducing network traffic by serving locally cached Web content. Web caching helps in reducing
bandwidth utilization during periods of high network traffic. High network traffic is usually caused
when a large number of users use the network at the same time. With a caching solution in place,
users’ requests will be returned from the cache without having to travel over a WAN link to the
destination Web server.
Answer option B is incorrect. Overclocking is the process of running a computer component, such as
CPU, at a higher clock rate than specified by the component manuurer. By increasing clock
frequencies of the components, the performance of computers can be improved at very little cost.
Users who overclock computer components generally try to enhance the performance of processors,
video cards, RAM, and motherboard chipsets. The overclocked components produce excessive heat.
Therefore, an effective cooling system is required to avoid damage to the hardware. Users who
practice overclocking often employ heavy-duty heatsinks and powerful fans.
