NFC (Near-Field Communication)operates atvery short ranges usually less than 4cm, and is ideal for quick, secure transactions like contactless payments.Bluetoothsupportslonger ranges (up to 10 meters or 32 feet)and is suited for ongoing connections like wireless headsets or file transfers.

Option A:Bluetooth is faster for large file transfers.

Option B:NFC usesless power, not more.

Option C:NFC doesnotrequire pairing Bluetooth does.

DisplayPort is a fully digital video interface that supports HDCP (High-bandwidth Digital Content Protection), a digital rights-management protocol used to protect copyrighted content such as movies, streaming video, and Blu-ray playback. The CompTIA A+ study guide notes that DisplayPort and HDMI support HDCP, while analog connections like VGA and DVI-A do not support HDCP because analog signals cannot enforce digital content protection.

F-type connectors are used for coaxial cabling (cable TV, satellite), not digital video output. DisplayPort ' s support for encrypted high-definition video streams makes it the correct answer and aligns with CompTIA’s coverage of display connectors and digital content protection technologies.

CompTIA A+ strongly emphasizes that virtual machines (VMs) are ideal for testing potentially unsafe software, malware samples, or experimental code because they isolate the environment from the host system. VMs allow snapshots, cloning, and rollback functionality, which makes them essential in development, QA, and cybersecurity environments where code might be unstable or harmful.

Hybrid cloud refers to infrastructure strategy, not code execution isolation. Load balancers distribute production traffic but have no testing or sandboxing purpose. Application gateways filter traffic but do not provide execution environments.

Virtual machines create a safe sandbox where failure, infection, or corruption is contained. This is covered in the Virtualization and Cloud Computing domain of the CompTIA A+ exam, making VMs the correct tool for executing unauthorized code safely.

A PoE injector is used to add power to an Ethernet cable, enabling the cable to deliver both power and data. This is crucial when connecting to PoE-enabled devices like IP cameras or wireless access points that are far from power outlets.

RAID 0 (striping) provides the fastest read (and write) speeds at the lowest cost, as all disk capacity is used for storage and performance. However, it offers no redundancy.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – RAID types:

" RAID 0 stripes data across multiple disks, offering the best performance and lowest cost but no fault tolerance. "

Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide)

CompTIA networking fundamentals describe VLANs (Virtual Local Area Networks) as a method to segment network traffic logically, even while using the same physical switch hardware.

A VLAN allows a company to:

Separate traffic by department

Improve security

Reduce broadcast domains

Control inter-department access

To separate accounting and customer service networks, VLANs are the industry-standard and the CompTIA-approved method.

Why the other options are incorrect

A. VPN – Used for secure remote connections, not internal LAN segmentation.

B. DNS – Resolves hostnames to IPs, not used for network separation.

D. DHCP – Assigns IP addresses; does not isolate network groups.

Final Answer: C

DHCP normally assigns IP addresses dynamically using timed leases, meaning the address may change after expiration. However, many devices—such as servers, printers, or specialized workstations—require permanent, predictable IP addresses. CompTIA A+ identifies a DHCP reservation as the correct method for assigning a consistent IP while still using DHCP.

A reservation binds a device’s MAC address to a specific IP address in the DHCP server. Each time the device requests an address, the DHCP server recognizes the MAC address and issues the same IP. This provides reliability while still allowing centralized management of network addressing.

A lease is temporary and not permanent. An exclusion simply removes certain IP addresses from the assignable pool—it does not assign any device a fixed address. A scope option configures additional network parameters such as DNS, gateway, or WINS settings but does not assign static IPs.

Therefore, a reservation is the correct method to permanently assign an IP address using DHCP without requiring static configuration on the device itself.

Satellite internet is commonly used in rural or remote locations where wired broadband options such as cable and fiber are not available and where DSL service may be limited by distance from the provider’s equipment. CompTIA A+ Core 1 emphasizes understanding internet connection types and where each is typically deployed. Satellite works by using a dish at the customer site to communicate with a satellite, which then relays traffic to a ground station connected to the internet backbone. Because it does not depend on local cable plant, telephone central office proximity, or neighborhood fiber buildouts, it can be deployed in areas with minimal infrastructure.

Fiber (A) provides very high speeds and low latency but requires extensive physical infrastructure that is often lacking in rural regions. Cable (D) also requires a local cable network buildout and is usually concentrated in more populated areas. DSL (C) uses existing telephone lines, but performance and availability depend heavily on distance from the DSL provider’s equipment, making it unreliable or unavailable in sparsely populated regions. While satellite often involves higher latency and can be affected by weather, it remains a primary option when traditional broadband services are not present.

Badging refers to the use of NFC-enabled ID badges or cards that authenticate users when tapped against a reader for secure print or access control.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – Secure printing and authentication:

“NFC authentication is commonly implemented using employee badges, allowing secure and convenient access to devices and functions.”
