220-1201 Practice Test 8 — 10 Questions

Question 1

A technician is configuring a new server and needs to ensure that only signed operating system bootloaders can be loaded. Which UEFI feature should be enabled?

Accepted Answer

Enable Secure Boot. Secure Boot enforces cryptographic verification of bootloaders, preventing unauthorized code from running during boot. This is a key security feature in UEFI. The question tests understanding of Secure Boot's purpose and implementation.

Answer

Enable Fast Boot

Answer

Enable Legacy Boot

Answer

Enable Boot from USB

Question 2

A technician needs to boot a laptop from a USB drive to run a diagnostic tool. The USB is plugged in but the system skips it and boots from the internal SSD. Which UEFI setting is most likely preventing the USB boot?

Accepted Answer

Disable Secure Boot. If Secure Boot is enabled and the USB is not signed or UEFI-bootable, the system may ignore it. Alternatively, the boot order may not include USB. This tests understanding of boot security and order settings.

Answer

Enable Fast Boot

Answer

Set SATA mode to RAID

Answer

Disable the TPM

Question 3

A user complains that their LCD monitor has a persistent dark spot in the center of the screen that does not change with different images. What is the most likely issue?

Accepted Answer

There is a stuck pixel.. This scenario describes a stuck or dead pixel, a common LCD defect. A dark spot that remains constant indicates a pixel that is not receiving power or is stuck in the off state. This is a hardware defect, not a software or connection issue.

Answer

The monitor's backlight is failing.

Answer

The graphics card is overheating.

Answer

The video cable is loose.

Question 4

A user reports that they can access internal resources using IP addresses but cannot access them using hostnames. Other users on the same network have no issues. What is the most likely cause?

Accepted Answer

The user's DNS settings are incorrect. The ability to use IP addresses but not hostnames points to a DNS resolution problem on the user's device. This could be due to a misconfigured DNS server address in the network settings or a local hosts file issue. Other users working normally suggests the problem is client-specific.

Answer

The DHCP server is out of addresses

Answer

The DNS server is down

Answer

The router's NAT is misconfigured

Question 5

A technician is troubleshooting a laptop that shuts down randomly after a few minutes of use. The fan is spinning, and the vents are clear. The CPU temperature reaches 95°C quickly. What is the most likely cause?

Accepted Answer

The thermal paste between the CPU and heatsink has dried out.. High CPU temperature despite a spinning fan indicates poor thermal transfer, often due to dried-out thermal paste or a heatsink that is not making proper contact. Reapplying thermal paste and reseating the heatsink is the solution. The fan working rules out a fan failure.

Answer

The fan is running at low speed due to a faulty fan controller.

Answer

The CPU is faulty and needs replacement.

Answer

The BIOS is set to an aggressive power-saving mode.

Question 6

A user reports that their laptop screen suddenly went black, but the laptop is still powered on (fans running, power light on). Connecting an external monitor shows the desktop correctly. What is the most likely cause?

Accepted Answer

The laptop's LCD inverter or backlight has failed.. The external display working normally indicates the GPU and OS are functional. The black built-in display points to a failure in the LCD panel, backlight, or the display cable (e.g., LVDS/eDP ribbon cable) connecting the motherboard to the screen. A loose or damaged internal cable is a common cause, especially in laptops that have been moved frequently.

Answer

The graphics driver has crashed and needs to be reinstalled.

Answer

The Windows display settings are set to 'Show only on external display'.

Answer

The laptop's RAM is faulty and causing video output issues.

Question 7

A user reports that they cannot send emails from their Outlook client, but they can receive emails. The email server is using standard ports. Which port is most likely blocked on the firewall?

Accepted Answer

25. Port 25 is the default SMTP port used for outgoing email transmission. If a firewall blocks port 25, the Outlook client cannot connect to the SMTP server to send emails, but receiving via POP3 (port 110) or IMAP (port 143) remains unaffected. This matches the user's symptom of being able to receive but not send emails.

Answer

110

Answer

143

Answer

443

Question 8

A technician is troubleshooting a laptop that has a blinking battery light and will not power on, even when plugged into AC power. The technician has already verified the AC adapter is working on another laptop. Which component is most likely faulty?

Accepted Answer

The battery. A blinking battery light often indicates a battery or charging circuit error. Since the AC adapter is known to be good, the issue is likely with the laptop's internal battery, the DC jack, or the charging circuit on the motherboard. The battery is the most common failure point.

Answer

The CPU

Answer

The RAM

Answer

The hard drive

Question 9

A technician is troubleshooting a network where users report intermittent connectivity. The technician finds that the switch logs show excessive CRC errors on multiple ports connected to different workstations. What is the most likely cause of these errors?

Accepted Answer

The Ethernet cables are run too close to power cables. CRC errors indicate data corruption at the physical layer, typically caused by electromagnetic interference (EMI) from nearby power cables. Running Ethernet cables too close to power cables induces noise, corrupting frames and causing CRC mismatches at the switch port.

Answer

The switch is configured with the wrong VLAN assignments

Answer

The workstations have duplicate IP addresses

Answer

The switch firmware is outdated

Question 10

A company's multifunction printer supports faxing over VoIP. Users report that faxes are frequently incomplete or fail to send. The fax line is connected to an analog telephone adapter (ATA). What should you check first?

Accepted Answer

Check the ATA's configuration to ensure T.38 fax relay is enabled.. Fax over VoIP is sensitive to jitter and latency. The ATA's settings for fax passthrough (T.38) must be enabled and properly configured. Without T.38, fax data may be corrupted by voice codecs.

Answer

Replace the fax modem card in the printer.

Answer

Increase the printer's print resolution.

Answer

Disable the printer's firewall.
