220-1201 Practice Test 33 — 15 Questions

Question 1

During a repair, you accidentally dislodged a small ribbon cable connecting the volume button flex to the mainboard of a smartphone. Now the volume buttons don't work. What is the most likely result of this mistake?

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

Accepted Answer

The volume buttons become unresponsive.. The volume button flex cable directly connects the physical volume buttons to the mainboard. Dislodging this cable interrupts the electrical circuit that carries the button press signal, so the buttons become unresponsive. This is a direct physical disconnection, not a software or power issue.

Answer

The phone won't power on.

Answer

The touchscreen becomes unresponsive.

Answer

The speaker stops producing sound.

Question 2

A technician is setting up a new tablet for a field worker who needs to capture signatures from customers. The tablet has a standard USB-C port. Which accessory is most appropriate for this task?

Accepted Answer

A capacitive stylus with a fine tip.. A capacitive stylus with a fine tip (Option B) is the most appropriate accessory because it allows the field worker to accurately capture signatures on the tablet's touchscreen. Capacitive styluses work by mimicking the electrical properties of a human finger, and a fine tip provides the precision needed for signature capture without relying on a digitizer or active pen protocol.

Answer

A Bluetooth keyboard for typing notes.

Answer

A USB-C to HDMI adapter for external display.

Answer

A screen protector to prevent scratches.

Question 3

A user reports that their laptop's built-in webcam is not working in any application. The device manager shows the camera with a yellow exclamation mark. The technician has already updated the driver to the latest version, but the issue persists. What should the technician do next?

Accepted Answer

Check the laptop's physical privacy shutter or function key (e.g., Fn+F10) that may disable the camera.. A yellow exclamation mark in Device Manager indicates a driver problem, but since updating the driver did not help, the issue may be a hardware conflict or a disabled device. The next step is to check if the webcam is physically disabled via a function key (e.g., Fn+F10) or a privacy shutter. Many laptops have a hardware switch or a keyboard shortcut to disable the camera for privacy.

Answer

Uninstall the webcam driver from Device Manager and restart the laptop to let Windows reinstall it automatically.

Answer

Replace the webcam module.

Answer

Disable and re-enable the webcam in Device Manager.

Question 4

A user complains that their laptop cannot connect to the company's wireless network, but other devices work fine. The network uses WPA2-Enterprise with 802.1X authentication. Which service is most likely misconfigured on the laptop?

Accepted Answer

The 802.1X authentication method is set to PEAP instead of EAP-TLS.. WPA2-Enterprise with 802.1X authentication requires the laptop to use a supplicant configured with the correct EAP method that matches the RADIUS server. If the laptop is set to PEAP (which uses a username/password or certificate) but the network requires EAP-TLS (which mandates client certificates), authentication will fail, preventing the laptop from connecting even though other devices with the correct configuration work fine.

Answer

The DHCP server is out of addresses.

Answer

The DNS server address is incorrect.

Answer

The RADIUS server is offline.

Question 5

During a network security audit, a technician finds that an employee is using a protocol that allows remote control of a computer with full graphical interface but without encryption. Which protocol should be replaced with a more secure alternative?

Accepted Answer

RDP. RDP (Remote Desktop Protocol) provides full graphical interface remote control but, by default in older versions or misconfigurations, transmits data without encryption, exposing keystrokes, screen content, and credentials to eavesdropping. The secure alternative is to use RDP with TLS/SSL encryption (e.g., via Network Level Authentication) or a VPN, or to replace it with an encrypted remote desktop solution like SSH with X11 forwarding or a modern RDP client enforcing encryption.

Answer

SSH

Answer

Telnet

Answer

FTP

Question 6

A technician is configuring a corporate iPhone for a new executive. The user needs to access company email, calendar, and contacts, but the company requires that all data be encrypted and the device be remotely wipeable. Which configuration step is essential?

Accepted Answer

Enable the device's passcode and Touch ID/Face ID.. Enabling the device's passcode and Touch ID/Face ID is essential because it activates hardware-backed encryption on iOS devices. Without a passcode, iOS cannot generate the encryption key required to protect data at rest, and remote wipe capabilities are contingent on the device being able to authenticate and enforce management commands. This step directly satisfies the corporate requirements for data encryption and remote wipeability.

Answer

Install a third-party antivirus app.

Answer

Disable iCloud backup for the device.

Answer

Set up a VPN connection for all traffic.

Question 7

A user's smartphone intermittently disconnects from a known Wi-Fi network when they move to a different room. The network uses a single access point. What is the most likely cause?

Accepted Answer

The smartphone is connecting to the 5 GHz band, which has poor wall penetration.. The 5 GHz band offers higher data rates but has significantly poorer wall penetration and range compared to the 2.4 GHz band. When the user moves to a different room, the signal from the single access point attenuates more rapidly at 5 GHz, causing intermittent disconnections. This is the most likely cause because the problem is location-dependent and occurs with a known network.

Answer

The access point is overloaded with too many clients.

Answer

The smartphone's MAC address is being filtered.

Answer

The smartphone's battery saver mode is turning off Wi-Fi.

Question 8

A technician is deploying a fleet of tablets for field workers who need to print invoices on a Bluetooth printer. The tablets are Android-based and support Bluetooth 5.0. The printer is an older model supporting Bluetooth 2.1. Which of the following is true about the compatibility between these devices?

Accepted Answer

The tablet and printer will connect but only at Bluetooth 2.1 capabilities.. Bluetooth is backward compatible, meaning a Bluetooth 5.0 device can connect to a Bluetooth 2.1 device. When paired, the connection negotiates the highest common version, which is Bluetooth 2.1. Therefore, the tablet and printer will connect but only at Bluetooth 2.1 capabilities, including its speed, range, and power consumption profile.

Answer

The tablet will not be able to pair with the printer due to version mismatch.

Answer

The connection will operate at Bluetooth 5.0 speeds and range.

Answer

The printer must be upgraded to Bluetooth 4.0 to work with the tablet.

Question 9

A technician is setting up a network printer that supports both standard and secure printing. Which port should be configured for secure IPP printing?

Accepted Answer

Port 631. Secure IPP (Internet Printing Protocol) uses HTTPS to encrypt print jobs and communications. Port 631 is the standard port for IPP, and when secured with TLS/SSL, it still uses port 631 but over HTTPS. This is defined in RFC 3510, which specifies how IPP operates over TLS, making port 631 the correct choice for secure IPP printing.

Answer

Port 9100

Answer

Port 515

Answer

Port 443

Question 10

A user reports that their email client cannot send messages but can receive them. The technician verifies that the email server is reachable and that the user's credentials are correct. Which protocol is most likely misconfigured in the email client?

Accepted Answer

SMTP. SMTP (Simple Mail Transfer Protocol) is used for sending outgoing email messages from a client to a server or between mail servers. Since the user can receive emails but not send them, and the server is reachable with correct credentials, the most likely misconfiguration is in the SMTP settings (e.g., wrong port, missing authentication, or incorrect server address).

Answer

POP3

Answer

IMAP

Answer

HTTP

Question 11

A marketing team uses tablets to capture customer signatures on glass screen protectors. They report that the capacitive stylus often skips or fails to register strokes near the edges of the screen. After testing, you find the issue persists even without the protector. Which accessory should you recommend to improve stylus precision?

Accepted Answer

A fine-tip active stylus. The issue persists without the screen protector, ruling out the protector as the cause. A fine-tip active stylus (Option C) uses a digitizer and Bluetooth or proprietary protocol to communicate with the tablet, providing precise edge-to-edge tracking. Passive capacitive styluses rely on the finger's electrical field and often fail near edges due to reduced capacitive coupling, making an active stylus the correct solution.

Answer

A tempered glass screen protector with an oleophobic coating

Answer

A Bluetooth keyboard

Answer

A different passive capacitive stylus with a larger tip

Question 12

A user needs to transfer files securely between two Linux servers over the internet. Which port should be allowed through the firewall for this purpose?

Accepted Answer

22. Secure file transfer between Linux servers typically uses SCP (Secure Copy) or SFTP (SSH File Transfer Protocol), both of which operate over SSH. SSH uses TCP port 22 by default, so allowing port 22 through the firewall enables encrypted authentication and data transfer. This is the correct choice because it provides confidentiality and integrity for the file transfer over the internet.

Answer

21

Answer

Answer

443

Question 13

A small business owner wants to connect five computers in a single office so they can share files and a printer without purchasing a server. Which network type should be configured?

Accepted Answer

Peer-to-peer network. A peer-to-peer network (B) is the correct choice because it allows five computers to share files and a printer directly without a dedicated server. Each computer acts as both a client and a server, making it ideal for small offices with fewer than 10 devices where centralized management is unnecessary.

Answer

Client-server network

Answer

Wide area network (WAN)

Answer

Metropolitan area network (MAN)

Question 14

A company's network uses a /24 subnet mask. The IT manager asks a technician to configure a new server with a static IP address of 192.168.1.300. The technician knows this is invalid. What is the reason this IP address cannot be used?

Accepted Answer

The octet value 300 exceeds the maximum of 255.. An IPv4 octet must be a decimal value between 0 and 255 inclusive. The value 300 exceeds this maximum, making the address 192.168.1.300 invalid. This is a fundamental rule of IPv4 addressing defined in RFC 791.

Answer

The address is outside the private IP range.

Answer

The address is a broadcast address.

Answer

The address is a network address.

Question 15

A customer reports that their new all-in-one printer can scan and copy locally, but they cannot send scanned documents to their email address. The printer is connected to the office network and can ping other devices. Which protocol is most likely misconfigured on the printer?

Accepted Answer

SMTP. The printer can scan and copy locally and is reachable on the network (ping works), but it cannot send scanned documents to an email address. This indicates the printer is configured to use SMTP (Simple Mail Transfer Protocol) to send the email, but the SMTP server settings (server address, port, authentication, or encryption) are likely incorrect or missing. SMTP is the standard protocol for sending outgoing email, which is exactly what the printer needs to deliver the scanned document as an email attachment.

Answer

FTP

Answer

IMAP

Answer

SNMP
