Describe the purpose and function of a baseline.

Describe the purpose and function of a baseline.

Set of statistics, taken under various conditions, used for future comparison. Without a baseline, there is really no way to answer claims such as “The server is slow” or “The network is slow.” Baseline comparison allows you to determine if there is indeed an issue affecting performance.

Describe a memory leak and the potential result of a leak occurring on the system.

Describe a memory leak and the potential result of a leak occurring on the system. One of the most common conditions that cause memory-related problems. Result of a program allocating memory for use but not freeing up that memory when it is finished using it. Over time, computer’s free memory can be totally consumed, degrading performance and ultimately halting the system.

Why are network performance issues the most difficult to track and solve?

Why are network performance issues the most difficult to track and solve?

They are difficult to quantify, develop gradually, often unreported, intermittent, tuning is based on educated guesswork, and solutions are often hard to sell upper management.

Explain difference between real-time and logged monitoring, and circumstances under which each is useful. What are examples of tools used for ?

Explain difference between real-time and logged monitoring, and circumstances under which each is useful. What are examples of tools used for ?

Real-time uses tools like Task Manager and System Monitor that display a continuous stream of statistics about what the system is doing right now. Provides most current information but must be continually monitored. Useful to address immediate issues critical to system performance or those affecting a single user on the network.

Explain difference between real-time and logged monitoring, and circumstances under which each is useful. What are examples of tools used for ?

Logged allows administrators to observe trends that develop over longer periods of time than those observed in real-time. Useful in determining if system performance has degraded over time an addressing less critical issues. Tools: Performance Logs and Alerts.

What is the purpose of backing up data?

What is the purpose of backing up data?

Back up data so we have copies of files available in case we are unable to access originals. Reasons for backing up data is because storage devices can fail, users can overwrite files by mistake, files can become corrupt, computers can get stolen, and we might need to look at an earlier version of a file.

What is a bottleneck? What is a common network performance bottleneck?  

What is a bottleneck? What is a common network performance bottleneck? Hardware device or software component that limits the performance of the system. Every system has a bottleneck. Question is whether bottleneck is actually causing a performance issue. In most cases the process of improving the performance of a system is simply identifying the component that is causing a bottleneck and upgrading it. Common bottlenecks: increased server load, hardware failure, changed server roles 

What three elements should a backup solution include?

What three elements should a backup solution include?

Backup device, backup software, and data that is to be backed up (and a plan to use backup tools).
