220-1201 Practice Test 7 — 10 Questions

Question 1

A technician is installing a new VoIP phone for a user. The user's desk already has a Cat6 wall jack, but the phone requires both network connectivity and a separate power source. The technician has a limited number of power outlets nearby. What is the simplest solution?

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

Accepted Answer

Use a Power over Ethernet (PoE) injector between the wall jack and the phone.. This question tests knowledge of Power over Ethernet (PoE) as a cabling-related concept. The correct answer is to use a PoE switch or injector, which sends power over the Ethernet cable, eliminating the need for a separate power adapter.

Answer

Run a new power extension cord from the nearest outlet.

Answer

Replace the Cat6 cable with a USB-C cable for power.

Answer

Install a wireless bridge to eliminate the cable.

Question 2

A technician is setting up a new office with 20 workstations. The cabling is Cat6, and all runs are under 90 meters. After terminating the cables at the patch panel and wall jacks, the technician tests each run with a cable certifier. One run fails the test for near-end crosstalk (NEXT). What is the most likely cause?

Accepted Answer

The cable pairs are untwisted too much at the termination point.. This question tests understanding of cable termination quality and crosstalk. The correct answer is that the untwisting of pairs at the termination point is too long, which can cause NEXT failures.

Answer

The cable is too long for Cat6 specifications.

Answer

The cable is not properly shielded.

Answer

The cable is damaged from being pulled too hard during installation.

Question 3

A user is setting up a new monitor that uses a DisplayPort connection, but their desktop PC only has an HDMI port. They have an adapter. Which adapter type will allow the monitor to display correctly?

Accepted Answer

HDMI to DisplayPort adapter. DisplayPort and HDMI are both digital video standards, and a passive adapter can convert between them without signal loss. This tests knowledge that DisplayPort and HDMI are electrically compatible for video, unlike VGA (analog) or USB-C (which may require active conversion).

Answer

HDMI to VGA adapter

Answer

DisplayPort to USB-C adapter

Answer

DVI to HDMI adapter

Question 4

A user complains that their external monitor flickers intermittently. The monitor is connected via a DVI cable to a graphics card that has both DVI-I and DVI-D ports. Which of the following is the most likely cause of the flickering?

Accepted Answer

The DVI cable is loose or damaged. A loose or damaged DVI cable is a common cause of intermittent flickering, as poor contact can disrupt the signal. DVI-I and DVI-D are compatible, so port type is less likely the issue. This tests troubleshooting skills for display connection problems.

Answer

The graphics card driver is outdated

Answer

The monitor's refresh rate is set too high

Answer

The DVI port is incompatible with the cable

Question 5

A technician is replacing a failed hard drive in a server. The new drive has a SATA III connector, but the server's backplane only supports SATA II. What will be the result of using this drive?

Accepted Answer

The drive will operate at SATA II speeds. SATA III is backward compatible with SATA II, so the drive will work but at SATA II speeds (3 Gbps). This tests knowledge of SATA generation compatibility and performance limitations. The drive will not be damaged but will not achieve its maximum speed.

Answer

The drive will not be recognized

Answer

The drive will operate at SATA III speeds

Answer

The drive will be damaged

Question 6

A user reports that their USB 3.0 external SSD is only achieving USB 2.0 speeds when connected to a front panel port. The technician checks the motherboard and finds the front panel header is connected to a USB 3.0 header. Which of the following is the most likely cause of the slow speed?

Accepted Answer

The front panel USB cable is damaged or not fully seated. A damaged or poorly connected front panel USB cable can cause the port to fall back to USB 2.0 speeds. The motherboard header is correct, so the issue is likely with the cable or connection. This tests advanced troubleshooting of USB 3.0 connectivity.

Answer

The SSD is formatted with FAT32

Answer

The motherboard BIOS needs updating

Answer

The SSD is connected via a USB 2.0 hub

Question 7

A technician is tasked with connecting a legacy printer that uses a parallel port to a modern laptop that only has USB ports. Which adapter is required to make this connection work?

Accepted Answer

USB to parallel adapter. A USB to parallel adapter allows a modern laptop to communicate with a legacy parallel printer. This requires an active adapter that converts USB signals to parallel. This tests knowledge of legacy connector adaptation and the need for active conversion.

Answer

USB to serial adapter

Answer

USB to PS/2 adapter

Answer

USB to VGA adapter

Question 8

A technician is troubleshooting a PC that powers on for a few seconds then shuts off. The technician removes the 24-pin connector and jumps the green wire to a black wire; the PSU fan spins and stays on. What does this indicate?

Accepted Answer

The motherboard has a short circuit causing the PSU to shut down.. The paperclip test confirms the PSU can power on independently. If the fan runs continuously, the PSU is likely functional. The issue is probably elsewhere, such as a short on the motherboard or a faulty component drawing too much power.

Answer

The power supply is definitely faulty and should be replaced.

Answer

The CPU is overheating and triggering thermal shutdown.

Answer

The power supply fan is defective, causing it to overheat and shut off.

Question 9

A technician is setting up a new network printer in a conference room. The printer has an RJ45 port for wired networking, but the only available wall jack is labeled with a different room number. The technician needs to connect the printer to the network. What is the best approach?

Accepted Answer

Use a tone generator and probe to trace the wall jack to the patch panel. The wall jack may be connected to a different network drop. The technician should use a tone generator and probe to identify which port on the patch panel corresponds to that wall jack, ensuring correct connectivity.

Answer

Connect the printer directly to the router using a long Ethernet cable

Answer

Assume the jack is functional and connect the printer

Answer

Use a WiFi adapter for the printer instead

Question 10

A technician is tasked with connecting a legacy projector that only has a VGA input to a modern laptop that has only HDMI and USB-C outputs. Which adapter should the technician use?

Accepted Answer

HDMI to VGA active adapter. Since VGA is analog and HDMI is digital, an active converter is needed. A USB-C to VGA adapter can work if the laptop supports video over USB-C, but an HDMI to VGA adapter is also an option if the laptop has HDMI. The best answer is an HDMI to VGA active adapter, as it directly converts the digital signal to analog.

Answer

USB-C to VGA passive adapter

Answer

VGA to HDMI cable

Answer

USB-C to HDMI adapter
