CompTIA Updated 220-1201 Exam Questions and Answers by essa

A private cloud is the best choice when an organization requires ownership and control of all physical hardware. In CompTIA A+ terms, a private cloud is a cloud deployment model where the cloud infrastructure is dedicated to a single organization and can be implemented on-premises (or hosted for that organization only). If the requirement explicitly states the organization must own the servers, storage, and network equipment, that aligns with a private cloud built and maintained using the organization’s own datacenter resources. This provides greater control over security, compliance, customization, and data governance compared with shared models.

A public cloud is owned and operated by a third-party provider, so the organization does not own the underlying hardware. A hybrid cloud combines private and public components; since part of it relies on provider-owned infrastructure, it does not meet the requirement of owning all physical hardware. IaaS and PaaS are cloud service models (what is consumed), not deployment/delivery models (how it is deployed), and they commonly run on provider-owned hardware as well. Therefore, Private cloud is the correct answer.

C. Initiate the system restore:

If the technician is confident that rolling back the system to a previous restore point will resolve the issue, the next logical step is to initiate the System Restore process.

System Restore allows the system to revert to a state before the OS update, which can eliminate the performance issues caused by the update.

Incorrect Options:

A. Document the findings: Documentation is important but should occur after resolving the issue.

B. Investigate any recent infrastructure changes: This is unnecessary if the issue is already attributed to the OS update.

D. Verify full system functionality: This step should be performed after the System Restore is completed.

Key Takeaway: When confident that rolling back will resolve the issue, the technician should proceed with initiating a System Restore to revert the OS.

Comprehensive and Detailed Step-by-Step Explanation:

When delivering 10Gbps speeds over long distances, fiber optic cables are the best choice. Here’s the breakdown:

A. Multimode Fiber (Correct Answer):

Multimode fiber is designed for relatively short to medium distances (up to 1,312 feet or 400 meters) while supporting high-speed data transfer (10Gbps and above).

It uses LED light sources and is cost-effective for environments like data centers or within buildings.

For the specified distance of over 328ft but under 1,312ft, multimode fiber is the most suitable option.

Incorrect Options:

B. Single-mode Fiber: While single-mode fiber supports much greater distances (up to several miles or kilometers) and higher speeds, it is more expensive and unnecessary for the specified range. Single-mode fiber is generally used for long-haul networking or telecommunications.

C. Cat 6a: Cat 6a is capable of 10Gbps speeds but only up to 328ft (100 meters). It cannot reliably handle the specified distance of over 328ft.

D. Cat 6: Cat 6 is also limited to 10Gbps speeds at distances up to 328ft (100 meters). Beyond this range, it is unsuitable.

Key Takeaway:

For delivering 10Gbps speeds over distances longer than 328ft (100m) but under 1,312ft (400m), Multimode Fiber is the best choice due to its ability to support high-speed data over medium distances at a reasonable cost.

A tablet’s display is made of two key parts that work together: the LCD (or OLED) that shows the image, and the digitizer that detects touch input. If the screen image looks normal but the device does not respond to taps, swipes, or gestures, the most likely failed component is the digitizer (or the digitizer layer/cable). The digitizer is a transparent sensor grid that converts touch into signals the system can interpret. When it fails, the tablet may still power on and show a clear picture, but touch will not register at all or will behave erratically.

Because the device shows no physical damage and a system reset does not fix the issue, this points away from a software glitch and toward a hardware input failure. Replacing the LCD screen is typically indicated when you see display problems such as no image, distorted colors, flickering, dead pixels, or backlight issues—not purely touch failure. A battery problem would affect power/charging, not touch responsiveness. A motherboard replacement is far more invasive and not the most likely first hardware fix for a touch-only failure. Therefore, the correct component to replace is the digitizer.
