CompTIA 220-1101 Practice Test

Explanation: If the touch-screen features on a Windows device have stopped working, a technician should check the Tablet/PC settings. The Tablet/PC settings contain options for configuring the touch-screen features on a Windows device. By checking the Tablet/PC settings, the technician can ensure that the touch-screen features are enabled and configured correctly. If the touch-screen features on a Windows device have stopped working, a technician should check the Tablet/PC settings. The touch-screen settings may have been disabled or there may be a driver issue that needs to be resolved. References: CompTIA A+ Certification Exam Guide, pg. 536

Explanation: The first step a technician should take before upgrading the Wi-Fi card on a laptop, or performing any internal hardware modifications, is to remove the power cable to ensure the device is not powered on. This is a crucial safety measure to prevent any electrical damage to the laptop or the technician. It also helps in avoiding any unintended changes or data loss that might occur if the device is powered on during the upgrade process.

Explanation: A smart card provides an additional factor of authentication by storing secure credentials, such as certificates, that cannot be guessed or replicated. It complements user accounts and is "something you have".
✑ Why Not A (Fingerprint reader): This is "something you are", but the scenario specifically requires a physical token.
✑ Why Not C (Secure token): Secure tokens are also valid but may not integrate as seamlessly into multi-factor authentication for physical and system access.
✑ Why Not D (NFC scanner): An NFC scanner is a device and not a token itself; it reads cards or other credentials.

Explanation: Mobile Device Management (MDM) allows IT departments to enforce compliance controls, such as restricting the installation of unapproved software, on laptops and mobile devices.
✑ Why Not A (EDR): Endpoint Detection and Response focuses on detecting and mitigating security threats, not compliance controls.
✑ Why Not B (VPN): Virtual Private Networks provide secure connections but do not enforce software installation policies.
✑ Why Not D (SaaS): Software as a Service refers to software delivery models and does not enforce compliance controls.

Explanation: When a printer is offline for one user but works for others, the issue often lies in the user's print queue settings, such as a paused queue or failed print jobs. Checking and clearing the print queue can resolve the problem.
✑ Why Not B (Check the printer's IP address): If other users can print, the printer’s IP address is not the issue.
✑ Why Not C (Check the user's network settings): Network issues are unlikely if the user can access other resources on the network.
✑ Why Not D (Check the printer's firmware version): Firmware issues would affect all users, not just one.

Explanation: Duplex printing allows printing on both sides of a paper, which can significantly reduce paper consumption and costs associated with buying paper. This makes duplex printing the best feature for cutting costs on consumables.

Explanation: Port 20 is used for FTP data transfer (along with port 21 for control), so enabling this port is required. Ports 23, 53, and 68 are unrelated to FTP functionality, as they correspond to Telnet, DNS, and DHCP respectively. CompTIA A+ Core 1 objectives outline the importance of knowing standard port numbers for network services.

Explanation: Containers are lightweight, isolated environments perfect for deploying and running microservices in a cloud or virtualized infrastructure.
