220-1201 Practice Test 4 — 10 Questions

Question 1

A small business runs a legacy application that requires Windows 7. The company wants to upgrade all desktops to Windows 11 while still running that application. Which virtualization solution would allow the application to run on the new OS without compatibility issues?

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

Accepted Answer

Use a Type 2 hypervisor such as VirtualBox to run Windows 7 as a virtual machine. This scenario tests understanding of application virtualization, where a legacy OS runs as a guest on a modern host. Using a Type 2 hypervisor like VirtualBox allows Windows 7 to run inside Windows 11, solving the compatibility problem without hardware changes.

Answer

Install Windows 7 in a dual-boot configuration

Answer

Deploy Windows 11 and use Windows 7 compatibility mode

Answer

Replace the legacy application with a cloud-based alternative

Question 2

A technician is setting up a temporary network for a conference where attendees' laptops need to share files directly without any central access point or router. The conference room has no existing network infrastructure. Which network type should be configured, and what is a potential security risk?

Accepted Answer

Ad hoc network; each laptop connects directly to others, but encryption may not be enforced.. An ad hoc network (IBSS) allows laptops to communicate directly without a central access point, which matches the requirement for direct file sharing with no existing infrastructure. The security risk is that encryption (like WEP or WPA2-Personal) may not be enforced by default in ad hoc mode, leaving data transmissions vulnerable to eavesdropping.

Answer

Infrastructure mode WLAN; configure a laptop as a software access point.

Answer

PAN network using Bluetooth; all laptops pair via Bluetooth.

Answer

Mesh network; each laptop acts as a node forwarding traffic.

Question 3

A user's iPhone connects to a public Wi-Fi hotspot but cannot load any web pages. The Wi-Fi icon shows full signal. Other devices on the same network work fine. What is the most likely issue?

Accepted Answer

The iPhone is not accepting the captive portal's terms and conditions.. The most likely issue is that the iPhone has connected to the Wi-Fi network but has not completed the captive portal authentication process. Captive portals require users to accept terms and conditions or log in via a web page before internet access is granted. Since other devices work fine, the network itself is functional, and the iPhone's full signal indicates a good physical connection, pointing to a failure in the portal acceptance step.

Answer

The iPhone's DNS settings are misconfigured.

Answer

The iPhone's Wi-Fi antenna is faulty.

Answer

The public Wi-Fi network is using an incompatible security protocol.

Question 4

A technician is building a new PC for a video editing workstation. The selected components include an Intel i9-13900K, an NVIDIA RTX 4080, 64GB DDR5 RAM, three NVMe SSDs, and six case fans. What is the minimum recommended power supply wattage for this build?

Accepted Answer

1000W. High-end CPUs and GPUs like the i9-13900K and RTX 4080 can draw over 300W each under load, plus other components. A 1000W PSU provides sufficient headroom for peak power spikes and ensures stability during intensive tasks.

Answer

750W

Answer

850W

Answer

1200W

Question 5

A small office uses an inkjet printer that has started leaving horizontal white lines across printed documents. The printhead cleaning cycle has been run twice without improvement. Which step should be taken next?

Accepted Answer

Perform a manual printhead cleaning using distilled water or a cleaning solution. Horizontal white lines on inkjet output indicate clogged nozzles in the printhead. If cleaning cycles fail, a more thorough cleaning using a manual method or a printhead soak may be needed. Replacing ink cartridges or the entire printer would be premature, and adjusting print settings does not address the physical clog.

Answer

Replace the ink cartridges

Answer

Adjust the print quality settings to 'Best'

Answer

Replace the printer

Question 6

A technician is troubleshooting a system that experiences random lockups and blue screens. The technician suspects a CPU issue but has already run a stress test without errors. Which diagnostic step should the technician perform next to isolate the problem?

Accepted Answer

Run a memory diagnostic tool like MemTest86. Random lockups and blue screens can also be caused by memory errors. Running a memory diagnostic tool like MemTest86 will test the RAM for faults, which can produce symptoms similar to a failing CPU. This helps rule out memory before replacing the CPU.

Answer

Replace the CPU with a known good one

Answer

Update the motherboard BIOS to the latest version

Answer

Check the CPU voltage in BIOS and increase it slightly

Question 7

A user reports that their laptop can connect to the internet via Ethernet but cannot connect to any Wi-Fi networks. The wireless adapter is enabled and shows available networks, but connecting always fails. What is the most likely cause?

Accepted Answer

The wireless security settings are incorrect.. When a device can connect via Ethernet but not Wi-Fi, the issue is usually with the wireless configuration or hardware, not the network itself. Incorrect wireless security settings, such as a mismatched encryption type or password, are a common cause of connection failure after the network is detected.

Answer

The DHCP server is out of IP addresses.

Answer

The wireless adapter driver is corrupted.

Answer

The router’s SSID is hidden.

Question 8

A technician is setting up a multifunction printer for a small business that wants to allow employees to print from their smartphones. The printer does not have Wi-Fi Direct, but it is connected to the company's wired network. Which solution would enable mobile printing?

Accepted Answer

Configure the printer to support AirPrint. This question tests knowledge of mobile printing solutions in a network environment. AirPrint is a built-in iOS feature that discovers printers on the same network via Bonjour. Google Cloud Print is deprecated, and Bluetooth or USB tethering are not suitable for a wired network.

Answer

Enable Bluetooth on the printer and pair it with each phone

Answer

Use a USB cable to connect each phone to the printer

Answer

Install Google Cloud Print on the printer

Question 9

A user's laser printer is producing pages with a repeating horizontal line defect every 3.75 inches. Which component is most likely causing this issue?

Accepted Answer

OPC drum. The distance between repeating defects often matches the circumference of a roller. In laser printers, the OPC drum is a common source of such defects. A defect repeating every 3.75 inches indicates a damaged component with a circumference of 3.75 inches. Some OPC drums have a circumference of approximately 3.75 inches (meaning a diameter of about 1.19 inches), making the OPC drum the most likely cause. Other components have different circumferences.

Answer

Fuser roller

Answer

Transfer roller

Answer

Toner cartridge

Question 10

A user reports that their inkjet printer prints blank pages even though the ink cartridges are full and the printer shows no error messages. The technician has already checked the ink levels and performed a nozzle check, which showed no ink on the test pattern. What is the most likely cause?

Accepted Answer

The printhead has failed and needs to be replaced.. Blank pages despite full cartridges and no errors often indicate a failed printhead that cannot deliver ink to the nozzles. The nozzle check pattern being blank confirms no ink is being ejected. A clogged printhead might show partial patterns, but a completely blank test suggests electrical or mechanical failure of the printhead.

Answer

The printer driver is corrupted and needs reinstallation.

Answer

The paper type setting is set to 'transparency'.

Answer

The ink cartridges are not properly seated.
