CompTIA 220-1101 Practice Test

Explanation: Enabling secure boot will verify the digital signature of the bootloader and operating system, ensuring that the system only boots from trusted and authorized sources. This can prevent booting from an unauthorized live CD or other external media. The best way to prevent booting from a live Linux CD on a computer in a shared space on campus is to enable secure boot. Secure boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs.

Secure Boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs. Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots)1.

Booting from a live Linux CD is a process that allows you to run a Linux operating system from a CD or DVD without installing it on your hard drive. This can be useful for testing or troubleshooting purposes. To boot from a live Linux CD, you need to insert the CD or DVD into your computer’s CD/DVD drive and restart your computer. Most systems are set up to automatically boot from the CD/DVD drive, but if your system is not set up this way, you may need to change a system setting to boot from a Linux CD/DVD23.

Explanation: The technician will need to connect the DVI port on the computer to the new display's HDMI port. To do this, a DVI to HDMI cable will be needed. This type of cable will allow the computer's DVI video signal to be transmitted to the new display's HDMI port. A digital-to-analog converter (DAC) is used to convert a digital signal to an analog signal. An A/V switcher is used to switch between multiple audio and video sources and display them on a single monitor or display. A DisplayPort to HDMI adapter is used to convert a DisplayPort signal to an HDMI signal, but it is not necessary in this scenario as the computer has a DVI port and not a DisplayPort.

Explanation: Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.
✑ Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.
✑ Why Not C (VPN): VPN secures communication but does not enforce device controls.
✑ Why Not D (SSL): SSL secures data in transit but does not provide device management.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, device management concepts.

Explanation: TPM 2.0 (Trusted Platform Module) is often disabled by default in the UEFI BIOS. Enabling it is necessary to meet the requirements for certain Windows installations, including Windows 11.
✑ Why Not B (Install an HSM): A Hardware Security Module (HSM) is a separate device used for cryptographic functions and is not related to TPM on the motherboard.
✑ Why Not C (Perform a clean install): A clean installation will not bypass the TPM 2.0 requirement.
✑ Why Not D (Implement BitLocker): BitLocker requires TPM but does not resolve its absence or lack of activation.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.4, BIOS/UEFI configuration.

Explanation: Verifying the correct type of paper is loaded is the best solution for resolving the issue of blank receipts being printed by a point-of-sale printer. Some receipt printers require a specific type of paper, and using the wrong type can result in blank receipts.

Verify the correct type of paper is loaded. If a point-of-sale printer is printing blank receipts, one possible cause could be that the wrong type of paper is loaded in the printer. Thermal printers require thermal paper to print properly. If regular paper is loaded instead of thermal paper, the printer will not be able to produce an image on the paper and will print blank receipts.

Explanation: The ticking noise likely indicates a failing hard drive. The technician should attempt to extract data before the drive fails completely.

Explanation: The concept described in the question is related to virtualization and resource management in a virtual environment. The approach that allows all virtual machines (VMs) to have memory (RAM) allocated for use is known as resource pooling. Therefore, the correct answer is D: "Resource pooling." This approach allows resources to be allocated dynamically to VMs based on their current needs, and ensures that resources are used efficiently in the virtual environment.

Resource pooling is a technique used in virtualization to share resources among multiple virtual machines (VMs). With resource pooling, RAM can be allocated dynamically to VMs as needed, allowing all VMs in a virtual environment to have RAM allocated for use.

Explanation: VGA (Video Graphics Array) is a legacy 15-pin connector used for transmitting analog video signals. VGA was commonly used to connect monitors to computers, but it has been largely replaced by more modern digital interfaces like DVI and HDMI.
✑ C. VGA: A legacy 15-pin connector used for analog video signals. Why the other options are incorrect:
✑ A. DisplayPort: DisplayPort is a newer digital interface and does not use a 15-pin connector. ✑ B. DVI: DVI (Digital Visual Interface) is a digital connector used for video signals but does not have 15 pins.
✑ D. HDMI: HDMI is also a digital interface for audio and video, but it uses a different connector with no 15 pins.

Explanation: NFC (Near Field Communication) devices commonly authenticate users through methods like badging, where a user’s badge or ID card, enabled with NFC, grants access. Passwords and passcodes are not NFC methods, while biometrics are typically used in high-security areas with specific hardware. NFC’s authentication, as outlined in the CompTIA A+ Core 1 objectives, facilitates access in environments needing convenient user verification.
