Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The replacement drive has a slightly smaller actual capacity than the original drives.. This question tests advanced RAID understanding. RAID 5 uses one drive's worth of capacity for parity, so three 1TB drives yield 2TB usable. The loss of 0.2TB suggests the replacement drive has slightly less capacity due to manufacturer differences or sector mapping.

Answer

The new drive has a different sector size (4K vs 512e).

Answer

The RAID controller is using some space for metadata.

Answer

The RAID 5 array is degraded and needs a second drive to be replaced.

Question 2

A technician is troubleshooting a desktop that has a 256GB SATA SSD (C:) and a 1TB SATA HDD (D:). The user reports that the system is running very slowly, and the C: drive is nearly full. The technician runs a disk cleanup and removes temporary files, but the C: drive still has only 5GB free. What should the technician do to resolve the performance issue without replacing the SSD?

Accepted Answer

Move the user's Documents, Pictures, and other personal folders to the D: drive.. This question tests understanding of SSD performance degradation due to low free space. SSDs need free space for wear leveling and garbage collection. When an SSD is nearly full, performance drops significantly. The best solution is to move user data and large files to the D: drive to free up space on the C: drive.

Answer

Enable write caching on the SSD in Device Manager.

Answer

Defragment the C: drive to consolidate free space.

Answer

Disable the page file on the C: drive.

Question 3

A user reports that their computer with a 256GB SSD and a 1TB HDD is running out of space on the C: drive (SSD). The user wants to move the 'Users' folder to the HDD to free space. What is the best method to accomplish this without data loss?

Accepted Answer

Use the 'Location' tab in the Users folder properties to change the target path to the HDD.. This question tests advanced storage management skills. Moving system folders like 'Users' requires using symbolic links (junctions) or the built-in 'Location' tab in folder properties to redirect the path without breaking system functionality.

Answer

Cut and paste the Users folder to the HDD, then create a shortcut on the SSD.

Answer

Format the HDD as a dynamic disk and extend the C: partition onto it.

Answer

Delete the pagefile on the SSD to free space.

Question 4

A technician is configuring a workstation for a graphic designer who needs to work with large 4K video files. The motherboard supports SATA III and has one M.2 slot. Which storage configuration will provide the best performance for this workload?

Accepted Answer

One NVMe M.2 SSD for both the OS and media files.. This question tests understanding of storage interface speeds. NVMe M.2 SSDs offer significantly higher sequential read/write speeds (up to 3500 MB/s) compared to SATA III (up to 550 MB/s), making them ideal for large file editing.

Answer

One SATA III SSD for the OS and one SATA III HDD for media files.

Answer

Two SATA III SSDs in RAID 0.

Answer

One SATA III SSD for the OS and one NVMe M.2 SSD for media files.

Question 5

During a routine hardware upgrade, you need to replace a power supply in a desktop that has a non-modular PSU. After disconnecting all cables, you notice the old PSU has a 20+4 pin main connector, but the new PSU has a 24-pin main connector. The motherboard has a 24-pin socket. What should you do?

Accepted Answer

Connect the new PSU's 24-pin connector directly to the motherboard. A 24-pin connector is compatible with a 24-pin motherboard socket; the extra 4 pins are integrated. The 20+4 pin design was for backward compatibility with older 20-pin boards. No adapter is needed.

Answer

Use the 20+4 pin connector from the old PSU on the new motherboard

Answer

Remove the 4-pin section from the new PSU's 24-pin connector to make it 20-pin

Answer

Use a 24-pin to 20-pin adapter

Question 6

A user complains that their smartphone's screen protector has started peeling off at the edges after a few weeks. They installed it themselves. What is the most likely cause of this problem?

Accepted Answer

The user did not clean the screen properly before installation, leaving dust or oil.. Improper cleaning leaves dust, oil, or debris on the screen, which creates microscopic gaps between the adhesive and the glass. These contaminants prevent full adhesion, causing the edges to lift over time as the protector is subjected to daily handling and temperature changes.

Answer

The screen protector is of low quality and does not fit the device model.

Answer

The smartphone case is too tight and pushes the protector off.

Answer

The device's screen has a factory oleophobic coating that repels the adhesive.

Question 7

A technician is troubleshooting a PC that powers on but does not display anything on the monitor. The fans spin, and the keyboard lights flash briefly. The power supply fan is spinning. What is the most efficient next step to isolate the issue?

Accepted Answer

Test the power supply output voltages with a multimeter. Testing the power supply with a multimeter or PSU tester is efficient because it quickly verifies if all rails are within spec. A failing PSU can cause no-post issues even if the fan spins. Other components like RAM or GPU could also be at fault, but checking power first avoids wasted effort.

Answer

Replace the power supply immediately

Answer

Reseat the GPU and RAM

Answer

Check the monitor cable connection

Question 8

A user reports that their MFP is making a loud grinding noise when printing, and the output pages have vertical streaks. The MFP is a laser printer with a separate toner cartridge and imaging drum. What is the most likely cause?

Accepted Answer

The imaging drum is damaged or worn.. Vertical streaks on laser printer output often indicate a damaged or worn imaging drum. The grinding noise suggests a mechanical issue with the drum rotation, which is a common failure point in laser MFPs.

Answer

The toner cartridge is low on toner.

Answer

The fuser unit is failing.

Answer

The paper tray is misaligned.

Question 9

A customer reports that their desktop computer intermittently freezes and emits a high-pitched whine. The issue occurs more frequently under heavy load, such as when rendering video. Which CPU-related feature is most likely causing this symptom?

Accepted Answer

Coil whine from the voltage regulator modules. The high-pitched whine from a CPU under load is typically coil whine, caused by electrical vibrations in the voltage regulator modules (VRMs) or inductors. This is not a sign of failure but can be annoying. The correct answer identifies the source as power delivery components, not the CPU itself.

Answer

CPU throttling due to overheating

Answer

A failing CPU fan bearing

Answer

Incorrect CPU multiplier setting in BIOS

Question 10

A small business uses an MFP that also functions as a network scanner. Users can scan to a shared folder on a Windows PC, but some users get an 'Access Denied' error when scanning. Other users can scan successfully. What is the most likely cause?

Accepted Answer

The MFP's scan-to-folder credentials do not have write permissions to the shared folder.. Scan to folder requires the MFP to have write permissions to the shared folder. If the MFP uses a generic service account, that account must have appropriate NTFS and share permissions. The issue is likely permission-related for the MFP's credentials.

Answer

The network switch port is faulty.

Answer

The MFP's firmware is outdated.

Answer

The Windows firewall is blocking the MFP.

Question 11

A technician is deploying an MFP that supports both USB and network connectivity. The office wants all users on the network to be able to print and scan from the device. Which connection method should the technician use?

Accepted Answer

Ethernet connection to the network switch. Network connectivity (Ethernet or Wi-Fi) allows multiple users to access the MFP simultaneously, while USB is limited to a single directly connected computer. For shared access in an office, network is required.

Answer

USB connection to a single workstation

Answer

Bluetooth connection to each user's device

Answer

Parallel port connection to a print server

Question 12

A user reports that when they scan a document to email from the office multifunction printer, the email never arrives. The printer shows a 'Connection to SMTP server failed' error. What is the most likely cause?

Accepted Answer

The SMTP server address or port is configured incorrectly.. This question tests knowledge of scan-to-email configuration. The SMTP server address or authentication credentials are the most common issues when a multifunction device cannot send email. Checking the SMTP settings in the printer's network configuration should resolve the problem.

Answer

The printer's IP address is set to static.

Answer

The toner cartridge is low.

Answer

The printer is out of paper.

Question 13

A small office has a multifunction printer that supports duplex printing. Users complain that when they select 'Print on Both Sides' from their application, the printer still prints single-sided. The printer driver is installed correctly. What should you check first?

Accepted Answer

Check the printer driver's default duplex setting and change it to 'Print on Both Sides'.. This scenario tests understanding of printer driver settings vs. application settings. Duplex printing must be enabled in both the printer driver properties and the application's print dialog. The driver default setting often overrides application choices if not set properly.

Answer

Ensure the printer has enough paper in the tray.

Answer

Replace the network cable.

Answer

Update the printer firmware to the latest version.

Question 14

A user tries to scan a document to a network folder from the multifunction printer, but receives 'Access Denied' error. The printer has been configured with the folder path and credentials. What is the most likely issue?

Accepted Answer

The user account used for scanning does not have write permissions to the folder.. Scan-to-network-folder requires the printer to have write permissions to the shared folder. Even if the path is correct, the credentials used must have 'Write' or 'Modify' permissions on that folder. This is a common misconfiguration.

Answer

The printer's IP address has changed.

Answer

The network folder share name has a typo.

Answer

The printer's hard drive is full.

Question 15

A company uses a proxy server for internet access. Users report that they can access internal websites but cannot reach external sites. The proxy server's IP is configured in the browser settings. Which network service is most likely failing?

Accepted Answer

Proxy server. The proxy server is configured in the browser settings, but users can reach internal websites (which bypass the proxy) while failing to reach external sites (which require the proxy). This indicates the proxy server itself is not functioning or unreachable, as it is the designated intermediary for external traffic. DNS, DHCP, and NAT would affect both internal and external access if they were failing, so the proxy server is the most likely culprit.

Answer

DNS

Answer

DHCP

Answer

NAT
