Which of the following is true about processor performance? A healthy system's CPU utilization should average around 40%. If a processor utilization is consistently high, your system is performing well. Utilization spikes as long as an application is open. Processor utilization is the amount of time the processor spends on idle tasks.
A healthy system's CPU utilization should average around 40%.
Where can you check your CPU's temperature? Performance Manager BIOS Device Manager Task Manager

Which of the following is the term for when a system is unable to keep up with the demands placed on it? Bottleneck Latency Jitter Hard fault
Bottleneck
Which of the following is a best practice when establishing a baseline? Establish baselines within a network or device's first week of installation. Establish baselines only during the busiest times of the day. Determine baselines over time by analyzing network traffic. Establish baselines using only specialized tools.
Determine baselines over time by analyzing network traffic.
Which of the following is the term for a calculation of how often bits are damaged in transit due to electromagnetic interference? Latency Bandwidth Error rate Bottleneck
Error rate
When packets arrive at their destination at different speeds, they sometimes arrive out of order. What does this cause? Jitter Error rates Latency Dropped packets
Jitter
What is the definition of bandwidth? The condition that occurs when a system is unable to keep up with the demands placed on it. The speed at which packets travel from source to destination and back. The calculation of how often bits are damaged in transit due to electromagnetic interference. The amount of data that can be transferred from one place to another in a specific amount of time.
The amount of data that can be transferred from one place to another in a specific amount of time.
Which of the following could be to blame if your computer is regularly crashing or restarting? Answer You've run out of bandwidth. You don't have enough memory. You're dropping packets. The processor is too hot.
The processor is too hot.
What is the definition of latency? The speed at which data packets travel from source to destination and back. The percentage of available bandwidth being used. The percentage of time that a disk subsystem reads from and writes to a disk. A calculation of how often bits are damaged in transit due to electromagnetic interference.
The speed at which data packets travel from source to destination and back.
Your computer seems to be running slowly. In particular, you notice that the hard drive activity light remains lit when you run multiple applications and switch between open windows. This happens even though you aren't saving large files. What should you do to troubleshoot the problem? Answer Use Task Manager to monitor disk activity. Use Resource Monitor to monitor disk activity. Use Reliability Monitor to monitor system reliability. Use Resource Monitor to monitor memory utilization.
Use Resource Monitor to monitor memory utilization.
