220-1201 Practice Test 33 — 15 Questions

Question 1

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 2

A technician is tasked with securing a workstation that will be used in a public kiosk. The requirement is that the system must only boot from the internal SSD and must prevent booting from USB drives or optical media. Which UEFI security feature should be configured?

Accepted Answer

Disable all external boot devices in the UEFI boot order and set a supervisor password.. Disabling all external boot devices in the UEFI boot order and setting a supervisor password ensures the system only boots from the internal SSD and prevents unauthorized changes to boot settings. The supervisor password protects the UEFI configuration from being altered. This directly meets the requirement.

Answer

Enable Secure Boot and set a UEFI administrator password.

Answer

Set the boot mode to Legacy BIOS and disable USB support.

Answer

Enable the TPM and set a power-on password.

Question 3

A company uses a public cloud IaaS provider. The security team discovers that a virtual machine's data disk was accidentally deleted by an administrator. They need to recover the data from a snapshot taken 24 hours ago. The snapshot is stored in the same cloud region. What is the most efficient recovery method?

Accepted Answer

Create a new data disk from the snapshot and attach it to the VM. Creating a new data disk from the snapshot and attaching it to the existing VM is the most efficient recovery method because it restores only the deleted data disk without affecting the OS disk or requiring a full VM rebuild. This minimizes downtime and preserves the VM's configuration, network settings, and other attached disks.

Answer

Restore the entire VM from the snapshot

Answer

Download the snapshot to an on-premises server and then upload it

Answer

Use the snapshot to create a new VM and then copy files via network

Question 4

A technician is troubleshooting a monitor that displays a 'fuzzy' image with ghosting. The monitor is connected via VGA. The technician has already tried a different VGA cable and the issue persists. What should the technician check next?

Accepted Answer

Route the VGA cable away from power cables and other electronics.. The symptoms described (fuzzy image with ghosting) are classic signs of electromagnetic interference (EMI) affecting an analog VGA signal. Since the technician has already ruled out a faulty VGA cable, the next logical step is to ensure the cable is not running parallel to power cables or near other electronics that can induce interference. Re-routing the VGA cable away from such sources can eliminate the ghosting without replacing hardware or changing settings.

Answer

Replace the monitor.

Answer

Change the resolution to a lower setting.

Answer

Update the graphics driver.

Question 5

A user reports that their laptop can connect to the corporate Wi-Fi but cannot access any network resources. The technician checks the IP configuration and sees an IP address of 192.168.1.105 with a subnet mask of 255.255.255.0 and a default gateway of 192.168.1.1. The technician pings the gateway successfully but cannot ping a server at 192.168.2.10. What is the most likely issue?

Accepted Answer

The default gateway does not have a route to the 192.168.2.0 subnet.. The technician can ping the default gateway (192.168.1.1) but not the server at 192.168.2.10, indicating that Layer 3 connectivity exists within the local subnet but fails beyond it. This points to a routing issue on the default gateway, which likely lacks a route to the 192.168.2.0/24 network. Without that route, the gateway cannot forward packets destined for the server, even though the laptop's IP configuration is correct.

Answer

The laptop's DNS server is misconfigured.

Answer

The server at 192.168.2.10 is offline.

Answer

The laptop's subnet mask is incorrect.

Question 6

A customer complains that their PC randomly shuts down after about 30 minutes of use, especially when playing games. The case feels warm to the touch. What should you check first?

Accepted Answer

Check CPU and GPU temperatures. Random shutdowns after ~30 minutes of use, especially during gaming, combined with a warm case, strongly suggest overheating. Checking CPU and GPU temperatures first is the most logical diagnostic step to confirm thermal throttling or shutdown protection.

Answer

Replace the power supply

Answer

Update the graphics driver

Answer

Run a memory diagnostic

Question 7

A technician is configuring a new workstation for video editing. After installing a high-end GPU and additional RAM, the system powers on but the screen is blank. The motherboard has diagnostic LEDs; the VGA LED is lit. What is the most likely issue?

Accepted Answer

Loose GPU power cables. A lit VGA diagnostic LED on the motherboard indicates that the system is failing the video initialization phase of POST. The most common cause after installing a high-end GPU is that the GPU's auxiliary power cables (6-pin or 8-pin PCIe power connectors) are not connected or not fully seated. Without adequate power, the GPU cannot initialize, and the motherboard halts at the VGA check.

Answer

Incompatible RAM

Answer

Faulty CPU

Answer

Monitor set to wrong input

Question 8

A network administrator notices that a managed switch is not reporting its status to the central monitoring system. The monitoring system uses a protocol that collects device information such as CPU load and interface errors. Which protocol is most likely not configured on the switch?

Accepted Answer

SNMP. SNMP (Simple Network Management Protocol) is the standard protocol used by network monitoring systems to collect device information such as CPU load, interface errors, and uptime. If the managed switch is not reporting to the central monitoring system, SNMP is most likely not configured or its community strings are misconfigured, preventing the monitoring server from polling the switch.

Answer

SSH

Answer

HTTP

Answer

ICMP

Question 9

During a BIOS update on a workstation, the power is interrupted, and now the system fails to POST. The motherboard has a backup BIOS chip. What is the most efficient way to recover the system?

Accepted Answer

Switch the motherboard's dual BIOS jumper to the backup position. When a motherboard has a dual BIOS (backup BIOS) feature, the fastest recovery from a corrupted primary BIOS is to switch the hardware jumper (or use the board's BIOS switch) to boot from the backup chip. This bypasses the corrupted firmware entirely and lets the system POST immediately, after which the backup can be used to reflash the primary. It requires no external media or lengthy power-drain procedures.

Answer

Replace the motherboard

Answer

Use a USB flash drive with the correct BIOS file and press a recovery key combination

Answer

Remove the CMOS battery for 30 minutes

Question 10

A technician is troubleshooting a laser printer that produces a ghost image of the previous page on the current page. The ghost image appears slightly offset. What is the most likely cause?

Accepted Answer

The drum's cleaning blade is worn. A ghost image that appears slightly offset on a laser printer is typically caused by a worn drum cleaning blade. The cleaning blade is responsible for removing residual toner from the drum after each page; when it wears out, leftover toner from the previous page remains on the drum and gets transferred to the next page, creating a ghost image. The offset occurs because the drum rotates slightly between pages.

Answer

The fuser temperature is too high

Answer

The toner cartridge is low on toner

Answer

The laser scanner is misaligned

Question 11

A network administrator is deploying a new wireless network in a large office building. They need to ensure seamless roaming for users moving between floors. The building has concrete floors and metal studs. Which hardware configuration will best support this requirement?

Accepted Answer

Deploy thin access points connected to a wireless LAN controller.. Thin access points (APs) are designed to be managed centrally by a Wireless LAN Controller (WLC). The WLC coordinates channel selection, power levels, and client handoffs, enabling seamless roaming across floors. In a building with concrete floors and metal studs, multiple thin APs with controlled overlap ensure consistent coverage and fast roaming without the interference issues that would plague overlapping channels on thick APs.

Answer

Install multiple thick access points with overlapping channels.

Answer

Use a single high-power access point in the center of the building.

Answer

Use mesh access points with wireless backhaul.

Question 12

A technician is configuring a company-issued Android tablet for a field worker. The worker needs to use a specific business app that requires location access to log job sites. What should the technician do to ensure the app works correctly?

Accepted Answer

Grant the location permission when the app requests it.. This question tests understanding of mobile app permissions. For an app that needs location data to function, the technician must grant the location permission when prompted or via settings. Denying or ignoring the permission will prevent the app from accessing location services, leading to malfunction.

Answer

Disable location services to save battery.

Answer

Install a third-party location spoofing app.

Answer

Set the tablet to Airplane mode to prevent network interference.

Question 13

A customer reports that their external USB 3.0 hard drive is not recognized when plugged into a specific port on their desktop, but works on other ports. The drive is powered by the USB bus. What should be checked first?

Accepted Answer

Inspect the USB port for debris or physical damage.. Because the drive works on other ports and is bus-powered, the most likely cause is a physical fault at the specific port—bent pins, debris, or wear—that prevents proper contact or power delivery. Inspecting the port for debris or damage is a non-destructive first step that isolates whether the problem is the port itself rather than the drive or software. This aligns with standard troubleshooting methodology: check the simplest physical cause before replacing hardware or changing configuration.

Answer

Replace the external hard drive.

Answer

Update the USB controller drivers.

Answer

Enable the USB port in the BIOS.

Question 14

A user complains that their cloud-hosted virtual desktop is slow to open applications and frequently disconnects. They are using a satellite internet connection. Which cloud characteristic is most likely being impacted?

Accepted Answer

Latency. Latency is the delay between a request and a response, and satellite internet inherently has high latency (typically 500–700 ms round-trip) due to the signal traveling to geostationary orbit and back. This delay directly impacts interactive cloud services like virtual desktops, causing slow application launches and frequent disconnects because the remote desktop protocol (e.g., RDP, ICA) is sensitive to round-trip time. High availability, elasticity, and scalability are cloud provider characteristics that are not directly affected by the user's network latency.

Answer

High availability

Answer

Elasticity

Answer

Scalability

Question 15

A customer reports that their multifunction printer (MFP) is not scanning to email. The MFP is connected to the network via Ethernet, and other network functions like printing work fine. What is the most likely cause of this issue?

Accepted Answer

The SMTP server settings are incorrect.. Scan to email requires the MFP to communicate with an SMTP server to send the email. Incorrect SMTP server settings are a common misconfiguration that prevents this function while other network services remain operational.

Answer

The MFP is out of toner.

Answer

The network cable is loose.

Answer

The scanner glass is dirty.
