1. A department is upgrading its printers and wants to save money on consumables. Which of the following printer features would allow the department to cut costs?
A. Collate
B. Duplex Correct
C. Secure print
D. Scanner
Explanation
Duplex printing allows for automatic double-sided printing, which reduces paper consumption by up to 50%. This directly cuts costs on paper, a primary printer consumable. Collate organizes printed output but doesn't save consumables. Secure print holds jobs until authentication, potentially saving paper from unclaimed prints but is less direct. A scanner is an input device, not a cost-saving print feature.
2. A user is unable to attach documents to an email. All attachments fail after several minutes. Which of the following troubleshooting steps should a technical perform first?
A. Establish a plan of action.
B. Test the theory.
C. Verify full system functionality.
D. Establish a theory of probable cause. Correct
Explanation
Establishing a theory of probable cause is the first logical step in troubleshooting. This involves gathering information and hypothesizing why attachments fail (e.g., large file size, network timeout, email server limits). Testing the theory and establishing a plan come after forming a hypothesis. Verifying functionality is a final step after implementing a solution.
3. A user arrives at the office and is unable to access the company's network on a smartphone. The user enables Wi-Fi on the smartphone, but it only shows the 5G symbol. Which of the following smartphone settings should the user configure in for this issue?
A. Autocorrect
B. VPN Correct
C. Encryption
D. WPS
Explanation
The 5G symbol indicates a cellular data connection, not Wi-Fi. The user likely needs to connect to the company's Wi-Fi network. A VPN (Virtual Private Network) is a common requirement for accessing corporate networks securely from personal devices. The user may need to configure VPN settings provided by their IT department. Autocorrect is for text input. Encryption is a security feature, not a connection setting. WPS is for simplifying Wi-Fi setup but isn't typically used for corporate network access.
4. A user's Windows computer started running slowly after the installation of a CAD program. The computer has intermittent network issues and often has to be restarted to restore functionality. The computer operates correctly if the application is not running. Which of the following should the technician do next to troubleshoot the issue? (Select two).
A. Replace the video card.
B. Research the requirements of the application. Correct
C. Install a new case fan.
D. Run `chkdsk` on the HDD.
E. Check the Event Viewer logs. Correct
F. Reinstall the application.
Explanation
Researching the application's requirements can reveal if the computer meets the necessary specs (CPU, RAM, GPU) and identify known issues. Event Viewer logs provide detailed system error messages and warnings that can pinpoint the cause of the slowdown and network instability, such as driver conflicts or resource exhaustion caused by the new software. Replacing hardware or running chkdsk is premature without diagnostic evidence from the logs or research. Reinstalling might help but should follow investigation.
5. Which of the following configurations is used to logically aggregate computers that are physically connected to the same network?
A. VLAN
B. VPN
C. VLAN Correct
D. MARI
Explanation
A VLAN (Virtual Local Area Network) is used to logically segment a physical network into multiple broadcast domains. This allows devices on the same physical switch to be grouped together logically, improving network management, security, and performance. VPN is for secure remote access. MARI is not a standard networking term.
