Free Practice Questions for CompTIA 220-1201 Exam

Dedicated resources (sometimes called single-tenant or bare metal) guarantee that physical hardware is allocated exclusively to one customer and not shared.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Cloud deployment models:

“Dedicated resources ensure data isolation at the hardware level for compliance and security.”

Inlaser printers, thefuser unitis responsible formelting the toner onto the paperusing heat and pressure. If the toner rubs off easily, it ' s a clear sign thefuser is failing or not heating properly. Replacing the fuser will ensure the toner bonds correctly to the paper.

Option B (Drum):Transfers the image, but doesn ' t fuse the toner.

Option C (Developer roller):Applies toner to the drum wouldn’t cause toner to rub off.

Option D (Discharge lamp):Prepares the drum for a new image; not related to toner adhesion.

PCIe (Peripheral Component Interconnect Express) is required for high-end video cards.

NVMe (Non-Volatile Memory Express) utilizes the M.2 or PCIe interface for the fastest SSD performance.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.2 – Motherboard expansion slots and storage interfaces:

“High-end video cards require a PCIe slot, while NVMe drives use M.2 (PCIe) slots for the highest data transfer rates.”

RAID 1 is known as mirroring. It duplicates all data to both drives simultaneously, providing redundancy in the event of a single drive failure. CompTIA A+ teaches that RAID 1 is ideal when reliability is the priority and only two drives are available exactly matching this scenario.

RAID 0 offers no redundancy. RAID 5 requires three or more drives. RAID 10 requires four or more drives.

Since the workstation has only two drives, RAID 1 is the only RAID configuration providing data protection and is heavily featured in CompTIA’s coverage of RAID technologies, their requirements, and their purposes in fault tolerance.

Virtual Desktop Infrastructure (VDI) delivers a desktop operating system hosted on a centralized server and streams the graphical user interface (GUI) to endpoint devices such as thin clients, zero clients, or standard PCs. According to CompTIA Core 1 (220-1201) virtualization objectives, VDI allows users to access their desktop environments remotely while all processing and data remain on the server.

Option A accurately describes this model: a GUI streamed from a server to thin clients. This approach improves centralized management, enhances security, and simplifies endpoint hardware requirements.

Provisioning a sandbox is an example of test or development virtualization, not desktop virtualization. High-performance workstations with a local OS are physical desktops, not VDI. Launching a virtual machine server on a hypervisor describes server virtualization, not desktop delivery.

CompTIA highlights VDI as a common enterprise solution that separates the desktop environment from the physical device, enabling flexibility, scalability, and centralized control.

When a newly built computer successfully passes POST, it indicates that the CPU, RAM, motherboard, video output, and other essential components are functioning at a hardware level. POST will typically fail or display error codes if there are problems with the CPU, RAM, GPU, or power delivery. Therefore, the fact that POST succeeds allows us to eliminate those components from suspicion.

The issue arises after POST, when the system attempts to load an operating system. For the OS to load, the BIOS/UEFI must detect a working storage device—such as an HDD, SSD, or NVMe drive—containing a bootable OS. If the computer cannot locate or read the drive, the system will halt at a boot error, such as “No boot device found,” “Insert boot media,” or similar messages. This is consistent with a failed or improperly connected HDD.

A failed HDD prevents access to boot files, even though the rest of the system hardware functions normally. Audio cards are irrelevant to booting. A failed CPU would cause a POST failure, not an OS loading issue. A faulty power supply would affect system stability during POST, not specifically OS boot failure unless the system is not powering at all.

Thus, the failed component is the HDD.

The most likely cause of slow charging after borrowing a charger is that the borrowed adapter is not the correct wattage or is not fully compatible with the laptop. Many laptops will still charge with an underpowered or non-matching adapter, but they often charge very slowly, may display a warning like “plugged in, not charging fast,” or may reduce performance to stay within the available power budget. In CompTIA A+ Core 1 troubleshooting, the first step is to check the simplest and most probable cause, especially when the symptom began immediately after a change. Using the proper manufacturer-recommended charger (correct voltage/amperage and connector type, or correct USB-C PD wattage profile if applicable) restores normal charging behavior in most cases.

Adjusting battery performance settings might reduce power draw but does not address the root cause of insufficient charger output. Trying a different charging port can help if a port is damaged, but the timing strongly points to the borrowed charger. Replacing the battery is the most invasive and least likely first step because the battery was presumably functioning before the charger change. Therefore, the technician should first use a different, known-good power supply with the correct specifications.

Infrastructure as a Service (IaaS) provides the foundational computing components: virtualized hardware, storage, networking, and hypervisor resources. CompTIA A+ explains that customers using IaaS are responsible for installing and maintaining:

The operating system

Applications

Patches, updates, and configurations

This model gives organizations maximum flexibility because they can build custom server environments without purchasing physical hardware.

In contrast:

SaaS (A) provides fully managed applications—users do not manage OS or software.

PaaS (B) provides a development platform and tools but does not allow OS management.

XaaS (D) is a broad term meaning “anything as a service,” not a specific model.

Thus, IaaS is the only model where OS-level control remains with the customer.

An A record maps a domain name to an IPv4 address in a DNS server.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.6 – DNS records:

“A records map hostnames to IPv4 addresses, while AAAA records map to IPv6 addresses.”
