A user reports that when scanning or copying from an MFP, lines appear to be running down the paper. The technician examines the printer and determines that it is processing jobs properly. Which of the following should the technician do to resolve this issue?
A. Replace the transfer roller.
B. Remove the pickup rollers.
C. Clean the glass bed.
D. Apply a maintenance kit.
Show Answer
Correct Answer: C
Explanation: Because printed jobs are processing properly, the issue is likely in the scanning path rather than the print engine. Dirt or debris on the scanner glass or ADF scan strip can create lines on scans and copies, so clean the glass bed.
Question 51
A technician is troubleshooting an all-in-one laser printer that prints a vertical line when making copies and scans. When users print or receive faxes, the output from the printer is correct. Which of the following should the technician examine to determine the cause of the issue?
A. The pickup rollers
B. The corona wire
C. The document feeder
D. The drum assembly
Show Answer
Correct Answer: C
Explanation: Copies and scans use the scanner/document-feeding path, while ordinary print jobs and incoming faxes use the printer’s imaging components. Since those outputs are clean, inspect the document feeder and its scanning path for dirt or debris causing the vertical line.
Question 51
A technician must upgrade a computer system to improve its overall processing performance. Which of the following should the technician focus on to ensure maximum system performance?
A. Integrated GPU
B. Power connectors
C. Voltage regulator module
D. Clock frequency
Show Answer
Correct Answer: D
Explanation: Clock frequency is the CPU’s operating speed, measured in cycles per second. A higher clock frequency can improve processing performance, making it the best choice among the options. The other choices concern graphics, power delivery, or voltage regulation rather than directly increasing processing speed.
Question 52
A user is having issues when charging a device with a Lightning cable. The cable is not recognized when it is plugged into the device. This issue is usually resolved by flipping the cable over. This issue does not occur with other devices of the same type. Which of the following would most likely cause the issue?
A. The device needs to be restarted.
B. The battery may be swelling and needs inspection.
C. The cable is failing and needs to be replaced.
D. The charging port is dirty or damaged
Show Answer
Correct Answer: D
Explanation: Because the cable works normally with other devices, the problem is most likely specific to this device. A dirty, obstructed, or damaged Lightning port can prevent reliable contact in one cable orientation.
Question 52
Which of the following will most likely be used in a testing environment to execute unauthorized code?
A. Virtual machines
B. Hybrid cloud
C. Load balancers
D. Application gateways
Show Answer
Correct Answer: A
Explanation: Virtual machines provide an isolated environment for testing or running untrusted code, limiting its impact on the host system. Hybrid clouds, load balancers, and application gateways serve different infrastructure or traffic-management purposes.
Question 52
Users have noticed their devices are frequently disconnecting or experiencing slow speeds in the company lobby, but the Wi-Fi signal is strong. Which of the following is the first step to troubleshoot the issue?
A. Increase the number of access points throughout the building to boost the overall signal strength.
B. Inspect the area for possible sources of interference or physical obstructions that could be disrupting the signal.
C. Recommend that all affected users switch to a wired connection to avoid wireless instability.
D. Change the wireless network frequency from 2.4GHz to 5GHz to enhance the connection stability and speed.
Show Answer
Correct Answer: B
Explanation: A strong Wi-Fi signal with poor performance or frequent disconnects commonly indicates interference, congestion, or environmental factors rather than insufficient signal strength. The first troubleshooting step is to inspect the area for sources of RF interference or physical conditions affecting connectivity before making configuration changes or adding hardware.
Question 53
A user's computer can connect to internal network resources but cannot access websites on the internet. Other users on the same network do not have this issue. Which of the following should a technician do first to troubleshoot the issue?
A. Verify the computer's DNS settings.
B. Replace the network cable.
C. Restart the DHCP server.
D. Adjust the firewall rules on the router.
Show Answer
Correct Answer: A
Explanation: The computer can reach internal network resources, indicating the local network connection is functioning. Because the issue is isolated to one device and affects only internet website access, DNS misconfiguration is the most likely first thing to verify. Replacing the cable is unlikely since LAN connectivity works, restarting the DHCP server would affect other clients and is not warranted for a single-host issue, and router firewall rules would typically impact multiple users rather than one device.
Question 53
Which of the following will a company most likely use to control which websites a user can access?
A. Proxy server
B. Spam gateway
C. DHCP server
D. RADIUS server
Show Answer
Correct Answer: A
Explanation: A proxy server can filter web requests and block access to specified websites, allowing a company to enforce browsing policies. A spam gateway filters unwanted email, DHCP assigns network configuration, and RADIUS handles authentication and access control.
Question 54
A user only has access to basic printer functions. A technician notices that the advanced printer features are missing. Which of the following actions will fix this issue?
A. Modifying the printer settings and rebooting the printer
B. Installing the drivers from the printer's manufacturer
C. Restarting the OS and attempting to reprint the document
D. Applying the OS-provided patches for the printer
Show Answer
Correct Answer: B
Explanation: Basic-only functionality usually indicates the operating system installed a generic driver. Installing the printer manufacturer’s full-feature driver enables the printer’s advanced features.
Question 55
A technician must install additional RAM in a desktop computer. Which of the following types of RAM will the technician most likely use?
A. Static
B. ECC
C. DIMM
D. Registered
Show Answer
Correct Answer: C
Explanation: Desktop computers typically use DIMM (Dual In-line Memory Module) memory modules. Static, ECC, and registered describe other memory characteristics or types, not the standard desktop module form factor.
