Pass the CompTIA A+ 220-1201 Questions and answers with CertsForce

The correct answer is A. Virtual LAN (VLAN).

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

VLANs are used to segment a physical network into multiple logical networks. By assigning the accounting department to a separate VLAN, users on other VLANs cannot access its network traffic without routing, thereby isolating sensitive departments while using the same physical switch.

VLANs improve security, reduce broadcast traffic, and allow network administrators to enforce access controls at the layer 2 level.

Why the other options are incorrect:

B. DHCP reservations: Ensure that specific devices always receive the same IP address, but do not restrict network access.

C. Content filtering: Controls web or application traffic based on content, not segmenting network access between departments.

D. Port security: Limits which devices can connect to a port but does not provide full network segmentation for an entire department.

In CompTIA A+ Core 1 (220-1201) cloud concepts, the key differentiator between cloud deployment models is where the service is hosted and who owns/uses the underlying infrastructure. If a company’s directory services server (for example, a domain controller providing authentication/authorization and centralized identity management) is located on premises, that points to infrastructure that is owned and operated by the organization for its own internal use. This aligns best with a private cloud model, which is defined as cloud resources dedicated to a single organization and can be implemented on-premises (internally hosted) or in a dedicated off-site environment.

It is not a public cloud because public cloud services are hosted by a third-party provider and shared across multiple customers. It is not hybrid cloud because hybrid requires a mix of on-prem resources and public cloud resources working together (the question only specifies on-prem). It is not community cloud because that involves shared infrastructure among multiple organizations with common needs.

The correct answer is A. 2.4GHz.

In the CompTIA A+ Core 1 220-1201 networking objectives, wireless networking technologies include frequency bands such as 2.4GHz, 5GHz, and 6GHz, along with related concepts like channels, regulations, channel selection, Bluetooth, 802.11 standards, NFC, and RFID.

The 2.4GHz band supports the most devices because it is the oldest and most widely adopted Wi-Fi frequency listed. Many legacy devices, including older laptops, printers, IoT devices, smart home devices, and wireless peripherals, still rely on 2.4GHz. It also has better range and wall penetration than higher-frequency bands, although it is usually more crowded and slower.

Why the other options are incorrect:

B. 5GHz

5GHz is newer than 2.4GHz and generally provides faster speeds with less interference, but it does not support as many older legacy devices.

C. 6GHz

6GHz is the newest Wi-Fi frequency option used with newer Wi-Fi standards, so it has the least legacy device support among the Wi-Fi frequency choices.

D. NFC

NFC is a short-range communication technology, not a Wi-Fi frequency band. It is used for close-proximity functions such as tap-to-pay, pairing, and access cards, so it is not the best answer.

Final Answer: A. 2.4GHz

Assigning a static IP to network printers ensures the printer ' s address does not change after outages or DHCP lease expirations, preventing connectivity issues.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – Printer network configuration:

“Printers should use static IPs to ensure they remain reachable and do not change addresses after network events.”

An SSD (Solid-State Drive) is the correct choice because it stores data using flash memory (NAND) and is commonly available in large capacities suitable for operating systems, applications, and mass storage. In CompTIA A+ Core 1 terms, SSDs contain no moving parts, which makes them faster and more reliable than mechanical drives for many workloads. They provide significantly improved read/write performance, lower latency, reduced heat output, and better shock resistance—important for both desktops and especially laptops. SSDs are also widely used in modern systems via SATA or NVMe (PCIe) interfaces, with NVMe offering the highest performance for large data transfers.

The other options do not match “flash memory”: DVD-RW is optical media with limited capacity and slower speeds, intended for removable storage rather than large-volume primary storage. An HDD can store large volumes of data but uses magnetic platters and moving heads, not flash memory. Tape is also magnetic media, typically used for backups and archival storage, and while it can store large amounts, it does not use flash and is designed for sequential access rather than fast random access. Therefore, SSD is the best answer.

Comprehensive and Detailed Explanation (100–150+ words):

Secure printing ensures that print jobs are not immediately output to the tray but instead held in a secure queue. The user must enter a PIN, password, or badge authentication directly at the printer to release the job. CompTIA A+ emphasizes secure printing as the correct method for environments where sensitive information such as HR files, performance reviews, or confidential reports must not be viewed by unauthorized individuals.

Audit logging tracks usage but does not protect documents from being seen on the printer tray. Wired connectivity has no relation to security or confidentiality. Duplex is simply a printing mode.

Secure printing is widely used in corporate environments so shared devices can remain shared without compromising sensitive data. The A+ curriculum describes this as a security control that ensures confidentiality in shared-print environments, making Secure Printing the proper solution.

According to the CompTIA A+ Core 1 (220-1201) virtualization objectives, a Type 1 hypervisor is known as a bare-metal hypervisor because it installs directly onto the physical hardware of a system rather than running on top of a traditional operating system. This architecture allows the hypervisor to manage hardware resources—such as CPU, memory, storage, and networking—without the overhead of a host operating system. Because of this direct interaction with the hardware, Type 1 hypervisors typically provide higher performance, better scalability, and improved stability compared to Type 2 hypervisors.

Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V (bare-metal deployment), and Citrix XenServer. These hypervisors are commonly used in enterprise data centers, cloud infrastructure, and large virtualization environments where multiple virtual machines must run efficiently on a single physical server. ???? ️

Option A (Host OS required) describes a Type 2 hypervisor, such as VMware Workstation or Oracle VirtualBox, which runs on top of an existing operating system. Option C (Lightweight OS) may describe some hypervisor environments but is not the defining characteristic. Option D (Local configuration options) is also not specific to Type 1 hypervisors.

Therefore, the key characteristic that defines a Type 1 hypervisor is that it performs a bare-metal server installation directly on the hardware

Refresh rate is the most relevant display attribute for reducing perceived motion blur and improving motion smoothness in fast-paced video or gaming. Refresh rate, measured in hertz, indicates how many times the display can update the image each second. A 120Hz or 144Hz display can present more individual frames per second than a 60Hz display, producing smoother movement and making rapidly moving objects easier to follow. Response time also affects ghosting because it measures how quickly pixels change from one state to another, but refresh rate is the broader attribute governing how frequently new frames are displayed. Resolution controls the number of pixels and therefore image detail, not motion smoothness. Color accuracy determines how faithfully colours are reproduced and does not directly reduce blur. For the best result, a high refresh rate should be paired with a low pixel-response time.

A DHCP reservation ensures a specific device always receives the same IP address from the DHCP server whenever it requests an address. The reservation is typically created by associating the device’s MAC address with a chosen IP address inside the DHCP scope. When that device connects and performs the DHCP process, the server recognizes the MAC address and offers the reserved IP instead of assigning the next available dynamic address. This is commonly used for devices that benefit from consistent addressing (for example, printers, servers, or network appliances) while still centrally managing addressing through DHCP rather than configuring a manual static IP on the endpoint.

An exclusion is the opposite idea: it defines a range of IP addresses within a scope that the DHCP server will not hand out (often because those addresses are used for statically assigned devices). A lease is the time period that a dynamically assigned IP address is valid before it must be renewed; it does not guarantee the same IP every time. A scope is the overall pool/range of IP addresses and DHCP options (gateway, DNS, etc.) available for a given subnet. Therefore, the component that guarantees the same IP is a reservation.

Amaintenance kitfor a laser printer often includesrollers, fuser, and other partsthat wear out over time. If the printer issmudging and misfeeding, it ' s a sign thatmultiple components are failing, which a maintenance kit is designed to resolve.

Option A (Fuser):May cause smudging if it ' s not heating correctly, but it won’t resolve paper misfeeds alone.

Option C (Corona wire):Can cause poor image quality if dirty but doesn’t affect paper feeding.

Option D (Toner cartridge):Can cause streaks if defective, but not paper feed issues.
