Free 220-1101 Practice Test Questions 2026

Explanation: Before attempting to resolve the issue, it is important to first determine the cause or probable cause of the issue, so that a plan of action can be developed. In this case, the fact that the retention policy was updated shortly before users first noticed the issue suggests that this could be the cause of the issue. The systems administrator should investigate this further to determine if this is indeed the cause of the email server issue.

Explanation: The ATX 3.0 16-pin connector provides power to high-end graphics cards, and a poor connection could lead to power issues and burning smells.

Explanation: SSH (Secure Shell) encrypts data communications for secure remote login and management of network devices, ensuring all console connections are encrypted.
✑ Why Not B (LDAP): LDAP is used for directory services and does not encrypt by default.
✑ Why Not C (FTPS): FTPS encrypts file transfers, not console communications.
✑ Why Not D (SMTP): SMTP is used for email transmission, not for securing login sessions.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, network security protocols.

Explanation: The correct answers are A. Identify the location of devices that utilize 2.4GHz and D. Map all of the wireless signals in the restaurant. In order to troubleshoot the issue, the technician should first identify the location of devices that utilize the 2.4GHz frequency, as this can cause interference with the wireless signal. Additionally, the technician should map all of the wireless signals in the restaurant in order to identify any potential sources of interference. Checking to see if the phones are IJTP or STP lines, testing to see if the copper electrical wires are causing interference, verifying T568B is being used in the wiring closet patch panel, and scheduling timed router reboots throughout the day are not necessary steps for troubleshooting this issue.

Explanation: For network printing, the required ports are typically those used by printing protocols. Port 515 is used by the Line Printer Daemon (LPD) protocol, and port 631 is used by the Internet Printing Protocol (IPP). These ports need to be opened in the firewall to allow print jobs to be sent to and from network printers.

Explanation: M.2 NVMe SSD provides the fastest data access possible for a laptop. It is a high-performance solid-state drive that connects directly to the motherboard through an M.2 slot.

Explanation: The 12VHPWR connector can supply up to 600 watts of power, designed for high-end graphics cards.
✑ Why Not A (400W): This is less than the connector’s maximum capability.
✑ Why Not B (MOW): This is an invalid option.
✑ Why Not D (700W): The maximum supported power is 600W.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.4, power supply and connectors.

Explanation: When a computer frequently freezes and requires hard restarts, the first step a technician should take, especially when hardware components have not been recently changed, is to read the event logs. Event logs can provide critical insights into what is causing the system to freeze, including errors and warnings that precede the freeze. This information is essential for diagnosing software or operating system issues that might be causing instability. Checking the temperature or updating drivers might be subsequent steps based on findings from the event logs.

Explanation: To terminate an RJ45 port, a technician should use a punchdown tool. This tool is specifically designed to insert and cut (terminate) the wires into a patch panel, keystone jack, or a network surface mount box. The punchdown tool ensures that the wire is properly seated in the terminal block and that the connection is secure. It also trims the excess wire during the termination process, which is not a function that cable testers, toner probes, or cable strippers are designed to perform.

Explanation: NFC (Near Field Communication) is a wireless communication technology that is commonly used for contactless payments, mobile payments, and other mobile transactions. It allows two devices to communicate with each other when they are placed in close proximity. Contactless payments commonly use NFC (Near Field Communication). NFC is a wireless communication technology that allows two devices to communicate with each other when they are in close proximity. Contactless payments use NFC to enable customers to make payments by simply tapping their contactless card or mobile device on a payment terminal.
