質問 # 369
A company wants to enable access to corporate email on smartphones. Employees must install software that separates corporate and personal data. Which should the company implement?
正解：A
解説：
The requirement to separate corporate and personal data on employee smartphones is a core function of Mobile Device Management (MDM). CompTIA A+ describes MDM as an enterprise toolset used to enforce security policies, manage applications, configure email profiles, and separate work-related data from personal user data. This separation is typically achieved through features such as containerization, where corporate data is stored in a protected, encrypted workspace that is isolated from the personal side of the device.
This ensures security, prevents data leakage, and enables IT administrators to remotely wipe corporate data without affecting the user's personal information. MDM solutions are widely used in BYOD (Bring Your Own Device) environments and corporate-issued devices.
Encryption (A) protects data but does not create separation. Network access control (B) restricts network access but does not manage mobile apps or data separation. Endpoint protection (D) refers to antivirus
/antimalware, not data partitioning.
Thus, Mobile Device Management (MDM) is the correct solution.
質問 # 370
A technician is replacing a failed power supply in a ten-year-old computer When installing the customer-provided power supply, the technician discovers the ATX connector would not plug into the motherboard. The customer wants a cost-effective solution. Which of the following should the technician do next?
正解：C
解説：
Older motherboards use 20-pin connectors, while newer power supplies use 24-pin connectors. An adapter resolves the compatibility issue cost-effectively.
Why Not A (Adjust the input voltage): Input voltage adjustment is unrelated to connector compatibility.
Why Not B (Install a modular power supply): While modular supplies are versatile, this doesn't address the connector issue directly.
Why Not C (Rebuild the failed power supply): Rebuilding is costly and complex compared to using an adapter.
CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.4, power supply compatibility.
質問 # 371
Which of the following connectors can be used to charge most modern mobile devices and may have the capacity to send data audio and video?
正解：A
解説：
USB-C is a versatile connector that supports charging, high-speed data transfer, and the ability to send audio and video signals (e.g., DisplayPort over USB-C).
It is used by most modern mobile devices and laptops because of its fast transfer speeds and power delivery capabilities.
質問 # 372
A technician needs to prepare a conference room for a meeting. The technician connects the laptop to the LCD projector and audio system, and then verifies the connectivity of each device. The meeting begins, but the visual presentation suddenly cuts off 30 minutes later. The audio continues to play without interruption.
The technician brings in a backup laptop and connects it to the projector. The meeting continues without issue for 15 minutes until the presentation suddenly cuts off again. Which of the following should the technician do to resolve this issue?
正解：D
解説：
Overheating is a common cause of projectors shutting down after extended use. A clogged air filter can cause overheating, resulting in intermittent shutdowns.
From CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 - Troubleshooting displays:
"If a projector shuts down after running for a period, clean or replace the filter to prevent overheating and automatic shutdown." Verified Source:

質問 # 373
A technician needs to replace a failed computer power supply. The customer wants to minimize the amount of heat the computer generates. Which of the following specifications should the technician recommend?
正解：C
解説：
A power supply with higher energy efficiency (such as 80 PLUS Gold or Platinum rated) converts more of the input power into usable output while wasting less energy as heat. This minimizes heat generation and improves overall system performance.
