Question 1

The organization of the file system on a server has no impact on network performance or security.

Accepted Answer

The organization of the file system on a server can impact network performance and security. For example, if sensitive data is stored in a publicly accessible location, it could be at risk of being accessed by unauthorized users. Additionally, if the file system is poorly organized, it could lead to slow access times and difficulty in managing files.

Question 2

Deleting temporary files on a Windows system is not necessary because Windows doesn't create temporary files.

Accepted Answer

Windows creates temporary files for various purposes, such as application data, system updates, and internet browsing. Deleting these files can improve performance and free up disk space.

Question 3

Which of the following is a method to defragment a hard disk?

Accepted Answer

Defragmentation involves reorganizing the files on a hard disk to optimize their placement and improve access times. The best method to defragment a hard disk is to use a specialized software tool that can analyze the disk and move files around as needed. Backing up the disk and doing a full restore or deleting applications and re-installing them may help to free up disk space, but they will not necessarily improve disk performance. Restarting the computer in the BIOS and resetting the BIOS to system defaults has nothing to do with defragmentation.

Question 4

Which of the following is NOT an argument for using RAID?

Accepted Answer

RAID (Redundant Array of Independent Disks) is primarily used for increased speed, increased storage capacity, and increased reliability. However, it may not necessarily decrease costs, as implementing RAID typically involves additional hardware and maintenance expenses.

Question 5

A differential backup backs up files that have the archive attribute set but does not reset the archive attribute.

Accepted Answer

A differential backup only backs up files that have the archive attribute set, but it does not reset the archive attribute like a full backup would. This allows for faster backups by only backing up changed files since the last full backup, but also requires a previous full backup to be useful.

Question 6

Which of the following is a file extension that indicates the file type of application in a Windows environment?

Accepted Answer

An .exe extension indicates that the file is an executable file, which means it is a program that can be run on a Windows environment. The other options do not relate specifically to application file types.

Question 7

Which command should you run on a Windows system to check for and fix problems with the file system?

Accepted Answer

Chkdsk is the command on Windows systems used to check for and fix problems with the file system. Fsck is a similar command used on Unix and Linux systems. p_fsck and dskrep are not valid commands.

Question 8

Which command should you use on a Linux system to find and print a list of files that begin with acctg that have been modified in the last 10 days?

Accepted Answer

The "find" command searches for files and directories based on various criteria. "-name" is used to specify the file name pattern to search, and "*" is a wildcard that matches any characters. "-mtime -10" specifies to search for files modified in the last 10 days. "-print" is used to print the list of files that match the criteria. None of the other commands provided have the correct syntax and options to achieve the desired result.

Question 9

Which of the following values is the recommended maximum percentage of disk space you should use for best reliability?

Accepted Answer

The recommended maximum percentage of disk space usage for best reliability is generally around 80%. Going beyond this threshold can lead to decreased performance and reliability issues as the system has less room to manage files and perform operations efficiently.

Question 10

If you analyze your disk and find that most of the files are stored contiguously on the disk,what should you do?

Accepted Answer

If most of the files are already stored contiguously on the disk, there is no need to run a disk defragmenting utility as that process is meant to consolidate and rearrange fragmented files. In this case, it is best to do nothing and leave the files where they are to prevent unnecessary disk activity.

Question 11

Which of the following commands should you use to delete files on a Linux system?

Accepted Answer

The "rm" command in Linux is used to remove or delete files and directories from a file system. It is the appropriate command for deleting files. "mv" is used to move or rename files, "delete" and "expunge" are not valid commands in Linux.

Question 12

If your Mac OS system displays a message indicating it is low on memory,which of the following is NOT a remedy to this memory fragmentation problem?

Accepted Answer

Plugging in a USB flash drive will not help with the memory fragmentation problem. The best solution in this case would be to implement virtual memory or restart the computer to free up memory. Closing all open applications may also help to free up memory.

Question 13

Which of the following is NOT a good rule to follow when creating a file structure?

Accepted Answer

Creating a folder for deleted files is not necessary, as they should be permanently deleted and not stored in a separate folder. This could also create confusion and clutter in the file structure.

Question 14

You find that disk operations on your server have gradually gotten slower. You look at the hard disk light and it seems to be almost constantly active and the disk seems noisier than when you first installed the system. What is the likely problem?

Accepted Answer

The symptoms suggest that the disk is heavily fragmented, causing the constant disk activity and increased noise as the read/write heads move around to access data across different areas of the disk.

Question 15

Virtual memory is a storage area in a computer's RAM that is set aside for the page file.

Accepted Answer

Virtual memory is a memory management capability of an operating system (OS) that uses hardware and software to allow a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage. This process is not limited to a specific area in RAM but involves the interaction between RAM and other storage devices, like a hard drive or SSD, where the page file or swap space is located.

Question 16

Which of the following is a database of information about the Windows operating system including customized settings and software installations?

Accepted Answer

The Windows Registry is a database of information that stores customized settings, configurations, and software installations for the Windows operating system. It is located in the \Windows\System32\Config folder and is a critical component of the Windows operating system. The registry is constantly being accessed and modified by the operating system, applications, and users, and is essential for the proper functioning of the system.

Question 17

You have used Windows Performance monitor and you are trying to locate the files created by this application. What is the name of the folder where Windows store the results of Windows performance tests?

Accepted Answer

The folder where Windows stores the results of Windows performance tests is called PerfLogs.

Question 18

Disk fragmentation causes reduced disk performance because the disk read/write heads must move longer distances.

Accepted Answer

Disk fragmentation causes files to be scattered across different areas of the hard drive, which means that the disk read/write heads have to move longer distances to access all the pieces of a file. This increases the time it takes to read and write data, resulting in reduced disk performance.

Question 19

Which of the following RAID configurations uses disk striping and includes the ability to replace a failed drive and rebuild the RAID without shutting down the server?

Accepted Answer

RAID 5 uses disk striping and includes the ability to replace a failed drive and rebuild the RAID without shutting down the server. RAID 0 does not offer any redundancy and RAID 4 does not offer the ability to rebuild without shutting down the server. RAID 1 uses mirroring instead of striping.

Question 20

You manage a server that users store their document files on. You are finding that some users are utilizing more space than they should with some very large files. What can you do to prevent users from taking up too much space on the server?

Accepted Answer

Setting up disk quotas allows you to limit the amount of space each user can use on the server. This way, users will not be able to exceed their allotted space, preventing them from taking up too much space on the server. Option A (setting stricter share permissions) can limit access to files and folders, but it does not necessarily prevent users from using too much space. Option B (sending a memo to users) is not effective as it relies on users' compliance and may not be practical for all users. Option D (deleting files over a certain size) can cause data loss and does not solve the fundamental issue of users utilizing too much space.
