Chapter 2 MCQs with answers: System Recovery and Advanced Maintenance

Book answer key: "a) - Monitor running applications". From the book: "Task Manager is a built-in tool in Microsoft Windows that helps users to monitor the performance of their computers." and "The Processes tab of the task manager shows all active programs and how much system resources they are using".

From the book: "This section introduces three important diagnostic tools available in Microsoft Windows: Task Manager, Resource Monitor, Event Viewer".

From the book: "Press the Ctrl + Shift + Esc shortcut key from the keyboard".

From the book: "Or right-click on the taskbar and select Task Manager from the menu".

From the book: "The Processes tab of the task manager shows all active programs and how much system resources they are using".

From the book: "while the Performance tab displays detailed graphs for CPU, memory, disk, and network usage."

From the book: "Select a program from the processes tab of task manager and click End Task to close it if it is not working properly (see Figure 2.1)."

From the book: "While Task Manager gives a quick overview, Resource Monitor provides more detailed information about which programs and background services are using system resources."

From the book: "It is especially helpful when the system is running slowly, overheating, or using a lot of memory without any clear reason."

From the book: "Or press the shortcut key Windows + R, type the command resmon in the dialog box that appears, and press Enter (see Figure 2.2)."

From the book: "Open Task Manager, go to the Performance tab, and click on Open Resource Monitor at the bottom."

From the book: "Memory Tab: Displays how much memory is used, free, or reserved."

From the book: "Disk Tab: Monitors which programs are reading from or writing to the hard drive."

From the book: "Network Tab: Shows which applications are sending or receiving data over the internet or network."

From the book: "Event Viewer is also a built-in Windows tool that records detailed logs of system activities." and "Press the shortcut key Windows + R, type the command eventvwr in the dialog box that appears, and press Enter."

From the book: "Safe Mode starts Windows with only the most fundamental drivers and services." The book's answer key gives b) Basic drivers only.

From the book: "Sometimes, a computer may stop working completely and fail to start. ... So, in this case, we use bootable recovery media to recover the system." The book's answer key gives b) System repair and recovery.

From the book (DO YOU KNOW box): "GPT is the modern standard. It supports disks larger than 2 TB, allows over 100 partitions, and is required for UEFI-based systems." The book's answer key gives c) GPT style. Note: "must" is the book's simplification. In Rufus the GPT choice is the one marked for UEFI, but many UEFI computers can also start from a USB made with MBR. For the exam, give the book's answer: GPT.

The book says "we learn about the three commonly used recovery tools" and then covers Safe Mode, System Restore and Bootable Recovery Media. Command Prompt is only listed as one of the built-in tools you can use after starting from bootable media.

From the book: "On some older systems: Restart and press F8 repeatedly before the Windows logo appears. Select safe mode, press enter."

From the book: "To enter it, follow the same steps as above and press F5 instead of F4."

From the book: "This version of Safe Mode includes network drivers, so you can access the internet."

From the book: "System Restore allows you to take your computer back to an earlier state without deleting personal files."

From the book: "Restore points are made automatically before system updates or driver installations, or manually by the user when it is needed."

From the book: "Go to System and Security, then click System. On the left, click System Protection. In the new window, under the System Protection tab, click the Create button."

From the book: "Bootable recovery media is a USB flash drive or DVD that contains important system files. It helps start the computer from an external device instead of the built-in storage."

From the book: "Startup Repair to fix problems that prevent Windows from loading." Command Prompt is listed "for advanced troubleshooting".

From the book (DO YOU KNOW box): "MBR is the older system. It supports up to 2 TB of disk size and a maximum of 4 primary partitions."

From the book: "iii. Right-click on the disk label (e.g., Disk 0), then choose Properties. iv. Go to the Volumes tab. Look at Partition Style."

From the book (SMART TIPS box): "If your computer uses GPT, but you create the USB in MBR format, it might not boot at all. The same happens if your system uses MBR and you use a GPT USB."

Book answer key: c) At system startup. From the book: "POST stands for Power-On Self-Test. It is the first thing the firmware does after the computer is turned on."

From the book: "All computers have special software built into the motherboard called firmware."

From the book: "It is not stored on the hard drive and does not get deleted when the computer is turned off. Firmware gives the computer basic instructions on how to start."

From the book: "how the Basic Input/Output System (BIOS) and Unified Extensible Firmware Interface (UEFI) help start the computer".

From the book: "BIOS older firmware software shows a basic, text-only menu and works with the keyboard only."

From the book: "UEFI newer type of firmware software, supports a graphical menu, that uses both mouse and keyboard, and larger hard drives."

The book lists three roles: "Checks if the hardware is working correctly (like RAM, keyboard, and hard drive)", "Finds the boot device (USB, hard disk, etc.) and starts the operating system" and "Allows users to change system settings like date, time, and boot order." Recovering deleted files is not one of them.

From the book: "POST stands for Power-On Self-Test."

From the book: "If all parts are fine, the computer continues to load the operating system. If something is wrong, it may beep or show an error message on the screen."

From the book: "Example: If the RAM is missing, the computer will beep continuously."

From the book: "Turn it on and immediately press a key like Del, F2, F10, or Esc (the correct key depends on the brand, like HP, DELL, and MSI)."

From the book: "If the wrong settings are saved, you can restore the system to its original state by selecting "Load Setup Defaults" or "Reset to Default" inside BIOS/UEFI settings."

From the book: "Boot order means the sequence in which the computer looks for a device to load the operating system."

The book's steps "How to Change Boot Order": "Enter BIOS/UEFI settings. Go to the Boot tab or menu. Move your desired device (e.g., USB) to the top of the list. Save changes and exit."

From the book: "Sometimes the computer cannot start due to missing files or errors. This can be fixed by using Startup Repair from Windows recovery USB or DVD."

Book answer key: b) Recover lost files. From the book: "Tenorshare is a free and easy-to-use file recovery program demonstrated in Figure 2.5."

Book answer key: b) Save copies of personal files. From the book: "File History is a backup feature in Windows. If it is turned on, the system keeps copies of your files at regular intervals."

From the book: "There are two main ways to recover deleted files: i. Using built-in tools. ii. Using third-party software."

From the book: "These tools are already part of the operating system, which is why we call them built-in tools."

From the book: "When a file is deleted in Windows, it usually goes to the Recycle Bin. It stays there until the bin is empty."

From the book: "You can open the Recycle Bin, right -click the file, and select Restore to bring it back to its original location."

From the book: "To turn it on, go to Settings > Update & Security > Backup, connect an external USB or Hard drive, and select "Add a drive"." (This is the Windows 10 path.)

From the book: "connect an external USB or Hard drive, and select "Add a drive". Once enabled, Windows will regularly back up your files like Documents, Pictures, and Desktop on that drive."

From the book: "Right-click the file or folder, choose Properties, then go to the Previous Versions tab. If available, you can select and restore an older copy."

From the book: "Sometimes, deleted files are not found in the Recycle Bin or Previous Versions. In such cases, you can try using third-party recovery software."

From the book: "It can scan your hard drive, USB, or memory card to find files that were recently deleted. You can then choose which files to recover."

From the book, step i: "Open Tenorshare, select the location from which you want to recover a file, such as a specific drive or folder(see Figure 2.5)." Then the type of file is chosen (step ii), "Scan" is clicked (step iii), and "Recover" is clicked (step iv).

From the book: "Recovery success depends on how recently the file was deleted and whether new data has overwritten it."

The book lists exactly three limitations: "If a file is deleted a long time ago, it may no longer be recoverable.", "Recovery is not always possible if the hard drive is damaged or formatted." and "Files may be permanently lost if the Recycle Bin is emptied, and no backups were made." Option d is not one of them.

From the book (SMART TIPS): "Always check the Recycle Bin first before trying advanced recovery tools. It is the easiest and safest way to restore deleted files."

Book answer key: "b) - Virus Protection". From the book: "Windows Defender is the built-in security tool in Windows that protects your computer from viruses, malware, and other threats."

From the book: "Preventive maintenance means doing simple tasks that help avoid bigger problems in the future."

From the book: "Disk Cleanup is a built-in Windows tool that helps remove such files safely." The "such files" are the unnecessary files the book lists just before.

From the book: "After some time, the computer collects unnecessary files such as temporary internet files, system cache, Windows update files, and items in the Recycle Bin."

From the book: "These files take up space and may slow down system performance."

From the book, step I: "Type Disk Cleanup in the Windows search bar and open the tool from the list. This opens a small window asking you to choose a drive to clean."

From the book, step II: "Select the drive you want to clean (usually C:) and click OK."

From the book, steps III and IV: "Check the boxes from the dialog box that appears after OK ... for the types of files you want to delete." Then: "Click OK to remove the selected files."

From the book: "Software updates, also known as patches, are released regularly by developers to fix bugs, add features, and improve security."

From the book: "Software updates, also known as patches, are released regularly by developers to fix bugs, add features, and improve security."

From the book: "There are two types of updates: I. Operating system updates (for Windows, macOS, etc.) II. Application updates (for programs like browsers, media players, etc.)"

From the book: "To check for updates in Windows: Open Settings > Update & Security. Click Check for updates. Install the updates if available." Note: this is the Windows 10 path; on Windows 11 the same button is under Settings > Windows Update.

From the book: "It offers two types of scans. Quick Scan to check common problem areas. Full Scan to check the entire system thoroughly."

From the book: "Windows Defender also provides real-time protection, which means it keeps watching your system in the background and alerts you if anything suspicious happens."

From the book: "A maintenance calendar helps you remember when to clean your system, scan for viruses, or check for updates. You can write it down or set reminders on your phone or computer."

From the book: "Keeping proper records is an important part of a computer system's maintenance."

From the book: "When we document what we do, such as installing software, fixing issues, or performing updates, it becomes easier to manage and troubleshoot systems in the future."

From the book: "When we document what we do, such as installing software, fixing issues, or performing updates, it becomes easier to manage and troubleshoot systems in the future."

From the book: "When we document what we do, such as installing software, fixing issues, or performing updates, it becomes easier to manage and troubleshoot systems in the future."

From book page 39 Answer Key: a) Monitor running applications. Topic 2.2 (page 23): "Task Manager is a built-in tool in Microsoft Windows that helps users to monitor the performance of their computers." and "The Processes tab of the task manager shows all active programs and how much system resources they are using". Disk cleanup is Disk Cleanup and virus scans are Windows Defender (topic 2.6).

From book page 39 Answer Key: b) Basic drivers only. Topic 2.3 (page 26): "Safe Mode starts Windows with only the most fundamental drivers and services. It disables unnecessary background programs and startup software". Note: the book's own sentence says "drivers and services", so option b is the closest choice, not a full quote. Option a is wrong because Safe Mode does NOT load all of them. Network drivers are added only in "Safe Mode with Networking" (page 26).

From book page 39 Answer Key: b) System repair and recovery. Topic 2.3 (page 28): "Sometimes, a computer may stop working completely and fail to start. In such cases, normal recovery options like Safe Mode and Restore Points may not work. So, in this case, we use bootable recovery media to recover the system." We use it when "You need to repair or reinstall the operating system."

From book page 39 Answer Key: c) GPT style. Topic 2.3, DO YOU KNOW box (page 29): "GPT is the modern standard. It supports disks larger than 2 TB, allows over 100 partitions, and is required for UEFI-based systems." Also page 28: "choose GUID Partition Table (GPT) for modern PCs and Master Boot Record (MBR) for older systems." Note: "must" is the book's simplification. In practice many UEFI computers can also start from a USB made with MBR. For the exam, give the book's answer: c) GPT style.

From book page 39 Answer Key: c) At system startup. Topic 2.4 (page 30): "POST stands for Power-On Self-Test. It is the first thing the firmware does after the computer is turned on."

From book page 39 Answer Key: b) Recover lost files. Topic 2.5 (page 32): "Tenorshare is a free and easy-to-use file recovery program demonstrated in Figure 2.5. It can scan your hard drive, USB, or memory card to find files that were recently deleted."

From book page 39 Answer Key: b) Save copies of personal files. Topic 2.5 (page 32): "File History is a backup feature in Windows. If it is turned on, the system keeps copies of your files at regular intervals." and "Windows will regularly back up your files like Documents, Pictures, and Desktop on that drive."

From book page 39 Answer Key: b) Virus Protection (printed with a capital P; same as option b). Topic 2.6 (page 35): "Windows Defender is the built-in security tool in Windows that protects your computer from viruses, malware, and other threats."
