CompTIA Updated 220-1201 Exam Questions and Answers by israel

The correct answer is C. ECC (Error-Correcting Code) .

In the CompTIA A+ Core 1 (220-1201) hardware objectives, RAM types and features include technologies designed to improve reliability and data integrity.

ECC memory is specifically designed to detect and correct data errors (faults) in memory automatically. It uses additional bits to store error-checking information, allowing the system to:

Detect single-bit and some multi-bit errors

Automatically correct errors without system interruption

Improve system stability, especially in servers and critical systems

This makes ECC the best choice for recovering from data faults .

Why the other options are incorrect:

A. Capacity

Capacity refers to how much data the RAM can hold (e.g., 8GB, 16GB). It has nothing to do with error detection or correction.

B. Speed

Speed (measured in MHz or MT/s) affects performance but does not provide any fault recovery capability.

D. DDR

DDR (Double Data Rate) refers to the generation/type of RAM (e.g., DDR3, DDR4, DDR5). It improves performance but does not handle errors.

E. Parity

Parity memory can detect errors but cannot correct them . Since the question specifically asks for recovery from faults, ECC is the correct answer because it both detects and corrects errors.

Final Answer: C. ECC

The correct answer is D. Restart the device .

According to CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:

Warning messages like this can be caused by malicious pop-ups or temporary software glitches . Restarting the device is the safest and quickest first step to clear temporary processes, refresh the system, and remove transient malware or pop-up overlays.

This approach addresses the issue without risking data loss or unnecessary downtime.

Why the other options are incorrect:

A. Force close all running applications: May help if a specific app is causing the pop-up, but restarting achieves this more reliably and fully resets background processes.

B. Replace the tablet with a newer device: Unnecessary and costly for a potentially temporary software issue.

C. Reset the device to default settings: This is a last-resort action, as it erases personal data and settings; it is not the first step.

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.

correct answer is " Overclocking " and " Reduce CPU Clock speed " CPU is at 4.5 Ghz when normal is 3.2 Ghz. Overclocking too much can cause freezes, and this is a gaming computer sothe user probably took it too far. http://blog.logicalincrements.com/2018/12/4-troubleshooting-tips-overclocking-pc/
