220-1101 Practice Test 22 — 15 Questions

Question 1

A user reports that they can access the internet and browse other websites normally, but when they try to visit https://www.example.com, the browser displays 'This site can't be reached'. Other computers on the same network can access the website. The technician has confirmed that the computer can ping the IP address of the website's server (93.184.216.34) successfully. The DNS settings appear correct. Which of the following should the technician check FIRST?

Accepted Answer

C. Verify the computer's hosts file has no entry for www.example.com. The hosts file (located at C:\Windows\System32\drivers\etc\hosts on Windows) is a local override for DNS resolution. Since the computer can ping the server by IP (93.184.216.34) but fails to reach the FQDN (www.example.com) via HTTPS, a misconfigured hosts entry could be redirecting the domain to an incorrect or unreachable IP, bypassing the otherwise correct DNS settings. This is the first check because it directly explains the symptom without affecting other computers.

Answer

A. Check the browser's proxy settings

Answer

B. Run the Windows Network Troubleshooter

Answer

D. Release and renew the DHCP lease

Question 2

A user's Android phone screen is cracked but still works. The user wants to continue using the phone temporarily without risk of glass cuts or further damage. What is the BEST immediate solution?

Accepted Answer

Apply a tempered glass screen protector. Applying a tempered glass screen protector over the cracked screen will hold the broken glass together, preventing glass fragments from falling out and reducing the risk of cuts. Replacing the digitizer is a permanent repair, not immediate. Using gloves is impractical for daily use and does not protect the phone from further damage. Removing the broken glass can expose internal components and is dangerous. A screen protector is the safest temporary measure.

Answer

Replace the digitizer

Answer

Use the phone with gloves

Answer

Remove the broken glass

Question 3

A user's workstation is unable to access the internet. The technician runs ipconfig and sees an IP address of 169.254.1.15 with a subnet mask of 255.255.0.0. What is the most likely cause?

Accepted Answer

The DHCP server is not responding.. The IP address 169.254.1.15 with a subnet mask of 255.255.0.0 is an Automatic Private IP Addressing (APIPA) address, which Windows assigns when a DHCP client fails to receive an IP lease from a DHCP server. This indicates that the DHCP server is not responding to the client's DHCP Discover messages, causing the client to self-assign an APIPA address and lose internet connectivity.

Answer

The default gateway is unreachable.

Answer

The DNS server is misconfigured.

Answer

The IP address is statically assigned.

Question 4

A user's Android phone has a cracked screen, but the touch functionality still works. The user wants to prevent glass fragments from falling out and to protect their fingers until the phone can be repaired. Which of the following is the BEST immediate action?

Accepted Answer

Apply a screen protector. Applying a screen protector is the best immediate action because it adheres to the cracked glass, holding fragments in place and providing a smooth surface to protect the user's fingers until a full repair can be performed. The touch functionality still works, so the digitizer (the touch-sensitive layer beneath the glass) is intact, meaning a simple protective layer is sufficient for temporary containment without interfering with capacitive touch sensing.

Answer

Replace the digitizer assembly

Answer

Power off the phone

Answer

Use a case that covers the screen

Question 5

A user's iPhone 11 is stuck in a boot loop after an attempted jailbreak. The device repeatedly shows the Apple logo and then restarts. The technician connects the iPhone to a computer; iTunes displays a message that the device is in recovery mode and must be restored. The technician attempts a force restart and tries a different USB cable and computer, but the iPhone remains in recovery mode and enters the boot loop after any restore attempt. Which of the following is the NEXT best step?

Accepted Answer

Perform a DFU restore. The iPhone is stuck in a boot loop after a failed jailbreak, and standard recovery mode restores are failing. A DFU (Device Firmware Update) restore bypasses the bootloader and iBoot, allowing the device to be completely wiped and the firmware reinstalled at the lowest level, which is necessary to recover from a corrupted boot chain caused by the jailbreak attempt.

Answer

Replace the battery

Answer

Replace the logic board

Answer

Update iOS using over-the-air (OTA)

Question 6

A user's iPhone is not receiving any cellular signal. The technician confirms that Airplane Mode is off, the device is not in a low-signal area, and the SIM card is properly inserted and not damaged. Which of the following should the technician try FIRST?

Accepted Answer

Reset network settings. Resetting network settings clears cellular and Wi-Fi configurations without affecting personal data, often resolving software-related signal issues. Changing the SIM card or performing a hard reset are more drastic steps. Updating carrier settings is less common as a first step.

Answer

Insert a different SIM card

Answer

Perform a hard reset

Answer

Update carrier settings

Question 7

A user's Android smartphone was dropped, causing the glass to shatter. The display still shows images correctly, and touch input works in most areas except for a small region near the top-left corner. The user wants to back up all internal data before taking the phone to a repair shop. Which of the following is the BEST method for the technician to back up the device's data immediately?

Accepted Answer

Use a USB-OTG adapter to connect a mouse. Option A is correct because a USB-OTG (On-The-Go) adapter allows the technician to connect a physical mouse to the Android device, providing an alternative input method to navigate the partially broken touchscreen. This enables the user to unlock the phone, access settings, and initiate a backup (e.g., to cloud storage or a connected USB drive) without needing the damaged touch area. It is the fastest and most reliable method when the display is still functional but touch input is compromised in a small region.

Answer

The device cannot be backed up until the screen is replaced

Answer

Use ADB from a computer, assuming USB debugging is already enabled

Answer

Remove the microSD card and copy data via a card reader

Question 8

A user's iPhone 12 is not making any sound during calls or notifications, but the ringer switch is not set to silent. The volume is turned up. The technician has already performed a force restart and updated iOS. Which of the following is the most likely cause?

Accepted Answer

The speaker grille is blocked by dirt or debris.. When an iPhone has no sound but the mute switch is off and volume is up, the most common cause is a blocked or dirty speaker grille. The Lightning port does not affect internal speaker audio. Bluetooth routing is possible but less likely unless a device is connected and the user is unaware. A swollen battery would cause physical distortion and other issues. Cleaning the speaker grille typically resolves this problem.

Answer

The lightning port is clogged with debris, preventing audio output.

Answer

The Bluetooth is enabled, causing audio to route to a disconnected device.

Answer

The battery is swollen, pressing against internal components.

Question 9

A user wants to synchronize their smartphone's contacts and calendar with their company's Microsoft Exchange server. Which protocol is specifically designed to provide this synchronization?

Accepted Answer

Exchange ActiveSync. Exchange ActiveSync (EAS) is a Microsoft protocol specifically designed to synchronize email, contacts, calendar, tasks, and notes between mobile devices and an Exchange server. It uses HTTP(S) and supports push synchronization, remote wipe, and policy enforcement, making it the correct choice for syncing contacts and calendar with a company's Exchange environment.

Answer

IMAP

Answer

POP3

Answer

SMTP

Question 10

A web application hosted on a public cloud platform automatically adds virtual server instances during high traffic and removes them during low traffic, without requiring manual intervention. This is an example of which cloud computing characteristic?

Accepted Answer

Rapid elasticity. The scenario describes a web application that automatically scales virtual server instances up and down based on traffic demand, which is the defining characteristic of rapid elasticity. This cloud computing feature allows resources to be provisioned and released elastically, often automatically, to match workload fluctuations. The key here is the automatic scaling without manual intervention, which distinguishes rapid elasticity from other characteristics like on-demand self-service, which focuses on user-initiated provisioning.

Answer

On-demand self-service

Answer

Broad network access

Answer

Measured service

Question 11

After a RAM upgrade, a PC fails to boot and emits memory beep codes. The technician confirms the modules are the correct generation. What is the best next step?

Accepted Answer

Reseat the RAM and test one module at a time in the recommended slot. Option C is correct because memory beep codes indicate a RAM-related issue, and the most common cause after an upgrade is improper seating or a faulty module. Reseating the RAM and testing one module at a time in the recommended slot (usually slot A2 or DIMM2 per motherboard manual) isolates the problem, ensuring each stick is properly installed and functional before adding more.

Answer

Replace the power button

Answer

Clear all browser cache

Answer

Disable DHCP

Question 12

A user wants to connect their smartphone to an external monitor for a presentation. The monitor only has a VGA input, and the smartphone has a USB-C port that supports DisplayPort Alt Mode. Which cable or adapter should the user obtain to connect the devices?

Accepted Answer

USB-C to VGA adapter. The correct answer is B because the monitor only has a VGA input, which is an analog video interface. The smartphone's USB-C port supports DisplayPort Alt Mode, which can output a digital DisplayPort signal. A USB-C to VGA adapter contains a digital-to-analog converter (DAC) that converts the DisplayPort signal from the phone into an analog VGA signal compatible with the monitor.

Answer

USB-C to HDMI adapter

Answer

USB-C to DisplayPort cable

Answer

Thunderbolt 3 to VGA cable

Question 13

A user's smartphone has a cracked screen. The display still shows images, but the touch input is completely unresponsive. The user needs to back up all data (contacts, photos, app data) before sending the phone for repair. The phone is not rooted, and no prior backup software was configured. Which of the following methods is the MOST reliable and complete way to back up the data in this situation?

Accepted Answer

Use a USB On-The-Go (OTG) adapter to connect a mouse to the phone, navigate to enable USB file transfer, then connect to a computer via USB cable.. Option B is correct because a USB OTG adapter allows connecting a mouse to the smartphone, enabling cursor control to navigate the touch interface. This lets the user access settings to enable USB file transfer mode (MTP), after which a computer can read the phone's storage for a full backup of contacts, photos, and app data. Since the screen is cracked but functional, and the phone is not rooted, this method provides complete control without requiring prior backup software.

Answer

Connect the phone to a computer using a USB cable; the computer should automatically detect it as a mass storage device, allowing file access.

Answer

Remove the SIM card and any microSD card, then connect the phone to a computer via USB to access internal storage directly.

Answer

Put the phone in a bag of rice to dry it out, then connect to a computer via USB, as the moisture may block the touch input.

Question 14

A user's smartphone with a removable battery begins to randomly shut down and restart. The technician notices that the battery percentage jumps erratically. Which of the following is the most likely cause?

Accepted Answer

The battery is worn out and needs replacement. The erratic battery percentage jumps and random shutdowns are classic symptoms of a worn-out lithium-ion battery that can no longer hold a stable charge. As the battery ages, its internal resistance increases and its voltage sags under load, causing the device's power management IC to misread the remaining capacity and trigger unexpected shutdowns. Replacing the battery restores stable voltage output and accurate fuel gauge reporting.

Answer

The operating system requires an update

Answer

The SIM card is loose

Answer

The screen is malfunctioning

Question 15

A user's smartphone screen does not auto-rotate when the device is turned sideways. The technician checks the 'Auto-rotate' setting and finds it is enabled. Which of the following components is MOST likely malfunctioning?

Accepted Answer

Gyroscope. The gyroscope is the component responsible for detecting the device's orientation and rotation. When auto-rotate is enabled but the screen does not respond to physical rotation, a malfunctioning gyroscope is the most likely cause, as it provides the angular velocity data needed to trigger the screen orientation change.

Answer

Proximity sensor

Answer

Ambient light sensor

Answer

Magnetometer
