CompTIA Updated 220-1201 Exam Questions and Answers by israel

The correct answer is B. Header pinouts.

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

Header pinouts on a motherboard are designated connectors for internal components such as USB ports, audio connectors, and front panel buttons/LEDs.

When adding additional internal USB ports, a technician typically connects them to the motherboard’s USB header pinouts. These headers provide the necessary data and power connections to enable USB functionality for front-panel or expansion USB ports.

Why the other options are incorrect:

A. TPM (Trusted Platform Module): Used for hardware-based security functions like encryption, not USB connectivity.

C. M.2 connector: Used primarily for SSDs and other small-form-factor expansion devices, not standard USB ports.

D. Expansion slots: Typically PCIe or PCI slots are used for expansion cards such as GPUs, network cards, or USB controller cards, but not for connecting internal USB headers directly.

The correct answer is D. DVI (Digital Visual Interface).

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

DVI is primarily a video-only interface that transmits digital or analog video signals from a source (like a computer) to a display.

Unlike HDMI or USB-C, DVI does not carry audio signals, making it strictly for video.

Why the other options are incorrect:

A. DisplayPort: Supports video and audio as well as other features such as daisy-chaining multiple monitors.

B. HDMI: Transmits both video and audio signals over a single cable.

C. USB-C: Can carry data, power, and video/audio signals depending on the device and protocol (e.g., DisplayPort Alt Mode).

The correct answer is D. Data is being throttled.

Data throttling refers to the intentional slowing down of internet speeds by a mobile carrier after a user reaches a certain data usage limit or during network congestion. In this scenario, the employee can still successfully upload files, but the speed has decreased compared to before—this is a classic symptom of throttling.

Why the other options are incorrect:

A. Wireless is turned off

If wireless were turned off, the employee would not be able to upload anything at all. The question clearly states that uploads are still successful.

B. 5G is disabled

Disabling 5G could reduce speeds slightly if the device falls back to 4G/LTE, but it would not typically cause a significant or noticeable degradation unless compared under ideal conditions. It is not the most likely cause.

C. Roaming is turned on

Roaming allows connectivity outside the home network. While it may incur additional charges, it does not inherently cause significant speed reduction in most modern networks. It is less likely than throttling.

Exam Tip (Core 1 220-1201):

Slow but working connection → Think throttling or congestion

No connection → Think disabled wireless or network issues

Final Answer: D. Data is being throttled

The correct answer is A. Containers.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud/Virtualization Concepts:

Containers provide lightweight, portable environments that package applications and their dependencies, allowing them to run consistently across multiple environments.

Containers are ideal for development teams because they require minimal underlying infrastructure, can be quickly deployed or destroyed, and isolate applications from the host system, making it easier to manage multiple applications simultaneously.

Why the other options are incorrect:

B. IaaS (Infrastructure as a Service): Provides virtualized hardware over the cloud but is more general-purpose; it includes virtual machines, storage, and networking, not minimal isolated application environments.

C. SaaS (Software as a Service): Provides fully managed software to end-users; not intended for deploying custom web applications by a development team.

D. Desktop virtualization: Provides virtual desktop environments to users; it does not provide a minimal, disposable platform for web application development.
