70-687 Configuring Windows 8.1 – sample exam – Q52

A company has a main office and three branch offices. The company has 20 portable computers that run Windows 8.1. Portable computer users can install local devices while in any branch office.
Your manager has instructed you to collect information about faulty devices and drivers within the company’s branch offices.
You need to create a performance report that includes a list of incorrectly installed devices by using the least amount of administrative effort.
What should you do?

A. Add counters from each portable computer to Performance Monitor, and then print the Performance Monitor output.
B. Start the System Performance Data Collector Set on each portable computer.
C. Start the System Diagnostics Data Collector Set on each portable computer.
D. Create and start a custom Data Collector Set on each portable computer.


Correct Answer: C

Explanation:
System Diagnostics You can use this DCS when troubleshooting reliability problems such as problematic hardware, driver failures, or STOP errors. It logs all the information included in the System Performance DCS, plus detailed system information.

Microsoft® Windows Vista® includes Windows Reliability and Performance Monitor, which is a Microsoft Management Console (MMC) snap-in that combines the functionality of previous stand-alone tools includ- ing Performance Logs and Alerts, Server Performance Advisor, and System Monitor. It provides a graphi- cal interface for customizing Data Collector Sets and Event Trace Sessions.

What is performance and reliability monitoring?
..
The reliability of a system is the measure of how often the system operates as it is configured and ex- pected to perform. Reliability can be reduced when applications stop responding, services stop and restart, drivers fail to initialize, or in the worst case, when operating systems fail.

Reliability Monitor provides you with a quick, visual view of the average stability of your system. In addi- tion, it tracks events that will help you identify what causes reductions in reliability. By recording not only failures (including memory, hard disk, application, and operating system failures), but also key events re- garding the configuration of your system (including the installation of new applications and operating sys- tem updates), you can see a timeline of changes in both the system and reliability, and can identify how to get your system back to optimal reliability when it does not behave as expected.

Data Collector Sets

An important new feature in Windows Reliability and Performance Monitor is the Data Collector Set, which groups data collectors into reusable elements for use with different performance monitoring scenar- ios. Once a group of data collectors is stored as a Data Collector Set, operations such as scheduling can be applied to the entire set through a single property change. You can schedule repeated collection of a Data Collector Set to create logs, load it in Performance Monitor to see the data in real time, and save it as a template to use on other computers.

Windows Reliability and Performance Monitor also includes default Data Collector Set templates to help you begin collecting performance data immediately.
