About the Exam 98-349: Windows Operating System Fundamentals Exam

Windows troubleshooting often starts by connecting an observed symptom to the subsystem involved. A slow startup after adding a peripheral calls for checking device and startup behavior; access by IP address but not computer name points toward name resolution rather than basic network reachability. Questions also sample core configuration decisions, such as enabling automatic wireless connection, using DHCP for address assignment, and selecting a firewall or drive-encryption feature for protection. Other concepts include virtual memory, device and driver management, windowing, and speech accessibility. Practicing these distinctions can help learners explain what common Windows components do, choose an appropriate first diagnostic step, and separate hardware, operating-system, security, and network causes without making unsupported changes.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

What is the main function of the Windows Firewall?

  1. ATo control network traffic according to configured rules
  2. BTo remove dust from computer components
  3. CTo recover deleted files from every storage device
  4. DTo manage the computer's screen brightness
Show answerCorrect answer: A

Windows Firewall helps protect a computer by allowing or blocking network traffic based on rules and profiles. It does not replace physical maintenance or data backups.

Question 2

Which Windows capability can encrypt the contents of an entire supported system drive to help protect data if the computer is lost or stolen?

  1. ABitLocker Drive Encryption
  2. BTask Scheduler
  3. CWindows Search
  4. DRemote Assistance
Show answerCorrect answer: A

BitLocker Drive Encryption protects data by encrypting a drive. On supported systems, it can encrypt the operating-system drive and may use a TPM or other startup authentication to help control access.

Question 3

A Windows computer is configured to obtain its network address automatically when it joins a network. Which service commonly supplies that address and related network settings?

  1. ADHCP
  2. BDNS
  3. CHTTP
  4. DSMTP
Show answerCorrect answer: A

The Dynamic Host Configuration Protocol (DHCP) can automatically provide a device with an IP address and other network configuration, such as a default gateway and DNS server addresses.

Question 4

A Windows computer is running low on memory because several applications are open. Which component temporarily moves less-used memory pages to disk to help make room for active work?

  1. AThe paging file
  2. BThe Recycle Bin
  3. CThe boot sector
  4. DThe clipboard
Show answerCorrect answer: A

Windows uses virtual memory, backed by a paging file on disk, to move less-active memory pages out of physical RAM when needed. Disk access is slower than RAM, but this can help the system continue operating under memory pressure.

Question 5

Which Windows interface is used to view hardware devices and check or update their device drivers?

  1. ADevice Manager
  2. BResource Monitor
  3. CDisk Cleanup
  4. DSystem Configuration
Show answerCorrect answer: A

Device Manager lists installed hardware and provides controls for inspecting device status and managing drivers.

Question 6

Which Windows component provides a graphical environment in which users can arrange and switch among running application windows?

  1. ADesktop shell
  2. BPrint Spooler
  3. CWindows Installer
  4. DTask Scheduler
Show answerCorrect answer: A

The Windows desktop shell provides core user-interface features, including the desktop, taskbar, and window management that users interact with during normal use.

Question 7

A laptop is connected to a wireless network, and the user wants Windows to connect to that network automatically in the future. Which setting should they enable when connecting?

  1. AConnect automatically
  2. BMetered connection only
  3. CAirplane mode
  4. DSet as a public folder
Show answerCorrect answer: A

The connect-automatically option tells Windows to join a known wireless network when it is available. Airplane mode, by contrast, disables wireless communications.

How to use this practice test

Access is free. Each practice session presents up to 20 random questions from the 50-question bank, with results shown after the session. Use missed or uncertain items to identify which Windows feature, tool, or troubleshooting distinction needs another review.

Preparation tips

  • Compare DHCP address assignment with DNS name resolution; practice diagnosing cases where IP access works but name-based access fails.
  • Review the purpose and basic use of Windows Firewall and BitLocker drive encryption, including the different risks each addresses.
  • Locate Device Manager and identify how it helps inspect hardware status and manage drivers; consider what to check after connecting a new USB device.
  • Explain how virtual memory supports active applications when physical memory is constrained, and distinguish it from installed RAM.
  • Practice finding wireless auto-connect and speech accessibility settings, and match each setting to the user need described.
