A group of friends is gathering in a room to play video games. One of the friends has a game server. Which of the following network types should the group use so they can all connect to the same server and the internet?
Correct Answer: C
The appropriate network type for this scenario is a Local Area Network (LAN), which is designed for small, localized networks, such as within a single building or room. LANs are ideal for gaming because they provide high-speed, low-latency connections. Option A (SAN): Incorrect. A Storage Area Network is used for data storage, not for gaming or general networking. Option B (MAN): Incorrect. A Metropolitan Area Network covers a city or campus, far exceeding the scope needed for a gaming setup in a single room. Option D (PAN): Incorrect. A Personal Area Network is designed for a single user, such as Bluetooth devices, and would not support multiple devices connecting to a game server.

Question 52
Which of the following components enables finger-based screen input for two-in-one laptops?
Correct Answer: B
A digitizer is the component in a two-in-one laptop that enables finger-based or stylus input on the screen. It is responsible for converting touch inputs into digital signals that the device can interpret. Why Digitizer? A digitizer is integrated into the screen assembly and works to detect and process inputs such as taps, swipes, or pinches. This is a standard feature in modern touchscreens, enabling functionality for both finger-based and stylus-based interactions.
Question 53
A company needs to develop a disaster recovery solution based on virtual machines. Which of the following service models is the most suitable?
Correct Answer: A
Infrastructure as a Service (IaaS)providesvirtualized computing resources over the internetsuch as servers, storage, and networking. It allows a business to quickly spin up virtual machines and is ideal fordisaster recoveryand scalable IT infrastructure needs. Option B:SecaaS focuses on cloud-delivered security, not infrastructure. Option C:PaaS offers development environments, not full virtual infrastructure. Option D:SaaS delivers applications over the internet (e.g., email, CRM) not for disaster recovery.

Question 54
An employee requires a workstation with three high-end graphics cards to render 3-D models. A technician must choose a power supply that meets the power requirements for the components and takes into consideration the mission-critical nature of the work. Which of the following meet the requirements? (Select two).
Correct Answer: B,D
A workstation running three high-end GPUs requires a power supply capable of both high wattage and stable, reliable output. In CompTIA A+ power supply fundamentals, modularity and redundancy are emphasized for high-performance and mission-critical systems. Modularity (B) allows the technician to connect only the necessary cables, reducing clutter, improving airflow, and enabling proper cable routing to multiple GPUs. High-end graphics cards require multiple PCIe connectors, and modular PSUs provide the flexibility to attach the exact number of required GPU power cables. This is important for systems where space management and cooling efficiency directly affect performance and component longevity. Redundancy (D) is critical for mission-critical workstations used for 3-D modeling and rendering. A redundant power supply ensures that if one PSU module fails, the system continues running without interruption. CompTIA A+ highlights redundancy as a key feature in professional environments where uptime is essential. These systems typically use dual hot-swappable power modules to guarantee continuous power delivery. The other options do not meaningfully address the requirements. A 12V output is standard on all PSUs. A 20-pin connector is outdated; modern motherboards use 24-pin. The 3.3V rail is not relevant to GPU loads, and 240 VAC input only refers to wall power compatibility, not PSU capability. Therefore, modularity and redundancy best meet the workstation's needs.
Question 55
Which of the following tools is best to track where an Ethernet cable is patched?
Correct Answer: D
Atoner probe (also known as a tone generator and probe) is the best tool for tracing and identifying cables in a patch panel or wall jack. The tone generator sends a signal through the wire, and the probe helps locate the cable by detecting the tone.
