Q1. You have just installed a second monitor for a bookkeeper's workstation so they can stretch their spreadsheets across both monitors. This would essentially let them use the two monitors as one combined larger monitor. Which of the followin…
Answer: D. Extended mode
Extended mode stretches the desktop workspace across multiple monitors, allowing a user to span applications like spreadsheets over a larger area. Refresh rate and resolution simply adjust display output clarity and do not combine screens.
Q2. Jonathan's father is visually impaired and is having difficulty seeing some of the items on his Windows 10 laptop. Which of the following Control Panel sections would a technician use to configure the Magnifier feature so that his father c…
Answer: A. Ease of Access
Ease of Access centralizes Windows accessibility tools like the Magnifier, narrator, and high contrast settings. File Explorer Options and Indexing Options manage folder views and search indexing, not visual assistance features.
Q3. Your company has just installed a new proxy server and has asked you to configure all of the Windows workstations to use it. Which of the following Internet Options tabs in the Windows Control Panel should you configure?
Answer: D. Connections
The Connections tab contains LAN settings where technicians configure proxy server addresses and ports for Windows workstations. The Privacy and General tabs manage cookies and browsing history instead of underlying network connections.
Q4. After diagnosing that battery optimization settings are preventing background services from starting on an Android device, a technician needs to restore functionality to email sync, weather updates, and cloud backup services. What is the B…
Answer: C. Disable battery optimization for the affected applications in the device settings
Disabling battery optimization for an app exempts it from Android doze restrictions so it can sync properly. Reinstalling the app fails because the operating system's power management restrictions will still throttle the new installation.
Q5. Which of the following allows a user to save their current session to memory, put a Windows 10 computer into a minimal power state and allow for the quickest time to return to functionality?
Answer: C. Sleep
Sleep mode saves the current session to RAM and enters a low power state, providing the fastest wake time. Hibernate writes the session to the hard drive and powers off completely, which takes longer to resume.
Q6. Dion Training has several Windows 10 Professional workstations with an internal 2 TB hard disk drive. The company wants to use full disk encryption to protect the contents of this hard drive. Which of the following security settings can be…
Answer: B. BitLocker
BitLocker provides full disk encryption for internal Windows hard drives to protect data at rest. BitLocker to Go is specifically for removable external drives, while FileVault is the macOS equivalent.
Q7. Jason is out of town on a business trip and needs to access the share drive on his company's corporate network. Which of the following types of network connections should he use to access the share drive from his hotel room?
Answer: B. VPN
A VPN creates a secure encrypted tunnel over the internet to connect a remote user directly to the corporate network. Dial-up, wired, or wireless are simply underlying physical connection types that do not provide secure remote access.
Q8. Which of the following Control Panel sections contains various tools like computer management, disk cleanup, print management, and the registry editor?
Answer: C. Administrative Tools
Administrative Tools is the correct answer because it houses advanced management snap-ins like Computer Management and Registry Editor. Device Manager only handles hardware, making it the strongest distractor that fails to fit the broad toolset described.
Q9. Dion Training has set up a lab consisting of 12 laptops for students to use outside of normal classroom hours. The instructor is worried that a student may try to steal one of the laptops. Which of the following physical security measures…
Answer: D. Cable locks
Cable locks physically secure laptops to desks, deterring theft in public or unsupervised areas. While biometric locks control access, they do not physically prevent someone from walking away with the laptop.
Q10. A hospital's file server has become infected with malware. The files on the server all appear to be encrypted and cannot be opened. The network administrator receives an email from the attacker asking for 20 bitcoin in exchange for the dec…
Answer: B. Ransomware
Ransomware encrypts files and demands payment for the decryption key. Spyware or keyloggers steal information secretly, but neither locks users out of their data while leaving a ransom note.
Q11. Which of the following types of backups only copies data modified since the last full backup?
Answer: D. Differential
A differential backup copies all data modified since the last full backup. An incremental backup is the strongest distractor, but it only copies data changed since the most recent backup of any kind.
Q12. What is the primary purpose of device encryption?
Answer: B. It protects stored data by making it unreadable without an encryption key.
Device encryption protects stored data by making it unreadable without the proper encryption key. Restricting network access or preventing software installation are security measures, but they do not scramble existing data.
Q13. Which of the following dictates what an employee can and cannot do when using the organization's computers and the enterprise network?
Answer: C. Acceptable use policy
An acceptable use policy dictates what employees can and cannot do when using company computers and networks. While least privilege limits access rights and zero trust requires continuous authentication, the acceptable use policy specifically defines the behavioral rules for system usage.
Q14. Dion Training wants to implement a new wireless network using WPA3 in their offices. Which of the following features of WPA3 is used to provide a password-based authentication using the dragonfly handshake instead of the older WPA 4-way ha…
Answer: B. SAE
Simultaneous Authentication of Equals, or SAE, provides password-based authentication in WPA3 using the Dragonfly handshake to replace the vulnerable four-way handshake. Enhanced Open encrypts traffic on open networks, while AES GCMP provides the actual data encryption rather than the authentication.
Q15. Which command-line tool is used on a Unix/Linux system to move upward on a directory in the system's directory structure?
Answer: A. cd ..
Using the cd command with the dot-dot parameter moves you up one level in the directory structure. A single dot represents the current directory, while ls lists files and dir is primarily a Windows command for listing directory contents.
Q16. An organization plans to upgrade its company-wide VPN solution, requiring thorough testing, stakeholder approval, and scheduled implementation. Since this change is not routine but also not an emergency, it must go through the full change…
Answer: B. Normal change
A normal change is a planned, non-routine modification that requires full change management processing, including risk assessment and stakeholder approval. Standard changes are pre-approved and routine, while emergency changes are reserved for unplanned incidents requiring immediate action.
