Try 3 A+ 220-1201 (V15) Core 1 practice questions
Choose an answer, explore the explanation, and see why the other options are less suitable. Three short scenarios. No sign-in required.
1. Pairing a Bluetooth keyboard
A user wants to pair a Bluetooth keyboard with a tablet, but Bluetooth is currently turned off. Before the technician can discover the keyboard or enter any pairing code, what should the technician do first?
Answer and full explanation
Correct answer: B — Enable Bluetooth on the tablet.
Why B is correct
Bluetooth must be enabled before the tablet can begin the pairing process with a Bluetooth accessory. The Core 1 objectives list enabling Bluetooth before enabling pairing, finding the device, entering a PIN when required, and testing connectivity. The clue is that the Bluetooth radio is currently turned off, so discovery cannot begin yet. Enabling Bluetooth addresses that prerequisite directly. Afterward, the technician can place the keyboard in pairing mode and continue through discovery and connection testing.
Why the other options are less suitable
- A — Enable the mobile hotspot: A hotspot shares the tablet's network connection with other devices. It is not required to pair a Bluetooth keyboard directly with the tablet.
- C — Enable location services: Location services support GPS and cellular location functions. They do not replace the need to turn on Bluetooth before pairing the keyboard.
- D — Enable cellular data: Cellular data provides internet connectivity through the mobile network. A local Bluetooth accessory can be paired without first enabling cellular data.
Key takeaway: For Bluetooth pairing, enable Bluetooth first, then discover, pair, authenticate if required, and test the connection.

2. Secure remote command-line access
A technician is configuring remote administration for a Linux server that sits behind a firewall. The administrator needs an encrypted command-line session from another network, and only the required service should be allowed. Which port and protocol should the firewall permit?
Answer and full explanation
Correct answer: C — TCP 22 for Secure Shell (SSH).
Why C is correct
CompTIA's Core 1 networking objectives associate Secure Shell (SSH) with port 22. SSH is the protocol in the listed choices intended for secure remote command-line administration. The scenario specifically asks for a Linux server and a secure administrative connection, making SSH the direct match. Allowing TCP 22 permits the expected SSH traffic through the firewall. The other listed ports serve different remote-access or application purposes.
Why the other options are less suitable
- A — TCP 3389 for RDP: Port 3389 is associated with Remote Desktop Protocol. RDP is a remote desktop technology, not the SSH command-line service requested here.
- B — TCP 443 for HTTPS: Port 443 is associated with HTTPS for secure web traffic. It would be appropriate for a web service, not the SSH administrative session described.
- D — TCP 23 for Telnet: Port 23 is associated with Telnet. Telnet does not meet the scenario's requirement for the secure remote command-line protocol identified in the objectives.
Key takeaway: Match the service to its purpose and port: SSH uses port 22 for secure remote command-line administration.
3. Faint output from a laser printer
A laser printer in an office has started producing uniformly faint pages. Its control panel also reports that the toner cartridge is nearly empty, while paper feeding and connectivity are normal. Which maintenance action is the most appropriate first response?
Answer and full explanation
Correct answer: D — Replace the laser printer's toner cartridge.
Why D is correct
The Core 1 hardware objectives identify toner replacement as a normal laser-printer maintenance task. The printer is already reporting low toner, and the output is uniformly faint, so the toner supply is the most direct maintenance item to address. Replacing the toner cartridge matches both the printer type and the symptom in the scenario. Other laser maintenance actions such as applying a maintenance kit, calibration, or cleaning may be useful under different conditions. Here, the low-toner warning makes toner replacement the best first response.
Why the other options are less suitable
- A — Clean an inkjet printhead: Printhead cleaning is associated with inkjet maintenance. The device in the scenario is a laser printer, so this action targets the wrong printer technology.
- B — Replace thermal paper and clean the heating element: These are maintenance tasks for thermal printers. They do not address a laser printer that is reporting low toner.
- C — Replace an impact-printer ribbon: Ribbon replacement is appropriate for impact printers. A laser printer uses toner rather than an impact ribbon to create output.
Key takeaway: Identify the printer technology first, then choose the maintenance item that matches both that technology and the observed symptom.

Requirements
- CompTIA recommends 12 months of hands-on experience in an IT support specialist job role; practical familiarity with device hardware, networking, peripherals, and troubleshooting will help with these scenarios.
- If parts of Core 1 are unfamiliar, combine question practice with foundational study from the official objectives and your own exercises such as hardware identification, SOHO networking, printer configuration, and virtual-machine setup.
- You will need an internet-connected device, a current web browser, and an ExamsDigest account to use the online practice product; do not rely on offline access or a separate mobile app.

Which CompTIA A+ exam version do these practice questions target?
Who is CompTIA A+ Core 1 practice for?
This practice is suited to learners preparing for entry-level IT support work and for candidates reviewing the Core 1 blueprint. CompTIA recommends 12 months of hands-on experience in an IT support specialist role. That is a recommendation, not a stated prerequisite in the objectives document. Familiarity with PC hardware, mobile devices, networking, printers, virtualization, cloud basics, and troubleshooting will make the scenarios easier to interpret.
How should I combine the practice questions with my Core 1 study?
What should I do when I answer a question incorrectly?
What question formats appear on the official 220-1201 exam?
CompTIA’s official 220-1201 objectives document lists multiple-choice and performance-based questions for Core 1. The three preview questions on this page are single-answer multiple-choice examples only, so they do not reproduce performance-based tasks or every format that may appear on the official exam. Use them to practise technical reasoning and objective recall, while preparing separately for task-oriented items described by CompTIA.
Does completing this practice earn the CompTIA A+ certification?
30-day conditional refund policy
