Whenever a user clicks on a .jpg, Notepad opens and displays illegible characters. Otherwise, the workstation functions normally. Which of the following is the most likely cause of this issue?
A. The workstation has been infected with malware.
B. The default application for image files is misconfigured.
C. The operating system needs the most current update.
D. A new image editor needs to be installed on the user’s computer.
Show Answer
Correct Answer: B
Explanation: Opening .jpg files in Notepad indicates that the file association for image files is set to Notepad instead of an image viewer. The system otherwise functioning normally rules out malware or OS issues, and no new editor is required—only correcting the default application.
Question 15
A technician recently installed a program that uses several anti-piracy technologies. When the program is launched, it briefly opens and then closes. Which of the following is most likely the reason?
A. 32-bit program on a 64-bit computer
B. CPU incompatibility
C. Outdated video card drivers
D. USB key not plugged in
Show Answer
Correct Answer: D
Explanation: Many anti‑piracy systems require a physical hardware dongle (USB key) to be present. If the dongle is missing, the application may briefly launch and then immediately close. The other options would typically produce clear error messages or prevent the system from operating normally rather than causing a silent exit.
Question 16
A user hears an unexpected noise coming from their desktop computer. To troubleshoot the issue, a technician needs to open the case. Which of the following actions should the technician take next?
A. Open the system cover.
B. Ground the system.
C. Disconnect the power.
D. Remove any peripheral devices.
Show Answer
Correct Answer: C
Explanation: Before opening a desktop computer case, the technician should first disconnect the power to prevent electrical shock and protect components. Grounding and removing peripherals are important, but they come after ensuring the system is powered off and unplugged.
Question 16
Which of the following concepts should a technician consider when discussing confidential work projects with individuals outside the company?
A. EULA
B. EOL
C. SLA
D. NDA
Show Answer
Correct Answer: D
Explanation: When discussing confidential work projects with individuals outside the company, the key concept is a Non-Disclosure Agreement (NDA), which legally obligates parties to protect sensitive information. EULA governs product use, SLA defines service expectations, and EOL refers to product lifecycle status.
Question 17
A technician completes malware remediation on a computer. Which of the following steps would most likely prevent future infections?
A. Enabling System Restore
B. User education
C. Scheduled AV scans
D. Symptom verification
Show Answer
Correct Answer: B
Explanation: User education is the most effective step to prevent future malware infections because many infections originate from unsafe user behaviors such as clicking malicious links, downloading untrusted software, or falling for phishing attacks. Educating users reduces the likelihood of these behaviors recurring, whereas the other options focus on recovery, detection, or verification rather than long-term prevention.
Question 17
A technician needs to change hibernation settings on a Windows computer by applying a batch file. Domain policies are unavailable. Which of the following is the best way to achieve this goal?
A. Update Power Options in the Control Panel.
B. Update the computer’s firmware.
C. Run gpupdate from a command prompt.
D. Use the powercfg command in PowerShell.
Show Answer
Correct Answer: D
Explanation: The requirement is to change hibernation settings by applying a batch file, with no access to domain policies. The powercfg utility is specifically designed to manage Windows power and hibernation settings from the command line and can be scripted in batch files or PowerShell. Control Panel changes are manual, firmware updates are unrelated, and gpupdate only refreshes existing Group Policy settings rather than configuring power options. Therefore, using powercfg is the best and correct solution.
Question 18
A user must perform a series of commands each day on a Linux server. The user wants to use a script to automate the process. Which of the following is the most likely file type for the script?
A. .js
B. .vbs
C. .bat
D. .sh
Show Answer
Correct Answer: D
Explanation: On Linux systems, shell scripts are typically written for the Bourne shell or compatible shells (e.g., bash) and use the .sh file extension. The other options correspond to scripting or batch files for different environments (JavaScript, Windows Script Host, or Windows batch files).
Question 18
Which of the following filesystems supports read and write operations for Windows, macOS, and Linux?
A. exFAT
B. ReFS
C. NTFS
D. APFS
E. ext4
Show Answer
Correct Answer: A
Explanation: exFAT supports native read and write operations across Windows, macOS, and Linux. The other options are platform-specific or have limited support: NTFS is fully supported on Windows but not natively writable on macOS without additional drivers; APFS is Apple-only; ext4 is primarily Linux; and ReFS is mainly supported on Windows Server.
Question 19
Independent contractors often work from a business's lobby. Although the business has Wi-Fi. contractors often plug in their laptops to Ethernet ports in the lobby. Which of the following should a security engineer do to most efficiently address a potential security concern with this network setup?
A. Configure WPA3 encryption on the Wi-Fi router.
B. Disable lobby ports and restrict external users to the guest wireless network.
C. Use a protocol analyzer to check for malicious traffic on the network.
D. Install signage telling external users not to use Ethernet ports.
Show Answer
Correct Answer: B
Explanation: Allowing external users to connect via Ethernet ports in the lobby can grant direct access to the internal network, bypassing wireless security controls. Disabling those ports and forcing contractors onto a segregated guest wireless network is the most efficient way to reduce risk by enforcing network segmentation. WPA3 only affects Wi‑Fi, monitoring traffic is reactive, and signage is ineffective.
Question 19
A company wants to use its directory database to authenticate users to its wireless network. Which of the following should the company use to accomplish this task?
A. MFA
B. WPA3
C. RADIUS
D. LDAP
Show Answer
Correct Answer: C
Explanation: To authenticate users to a wireless network using an existing directory database, the company should use RADIUS. RADIUS is the standard AAA protocol used with enterprise Wi‑Fi (e.g., 802.1X) and can integrate with directory services like Active Directory or LDAP for user authentication. LDAP itself is just a directory access protocol and is not used directly by wireless access points for authentication.
