질문 # 284
A company wants to enable access to corporate email on smartphones. Employees must install software that separates corporate and personal dat a. Which should the company implement?
정답：B
설명：
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.
질문 # 285
A technician upgrades a CPU heat sink with a higher-performing model. While stress testing the computer, the technician finds that the CPU temperatures have drastically increased. Which of the following is most likely causing the issue?
정답：A
설명：
Whenever a CPU heat sink is removed or replaced, thermal paste must be reapplied. Thermal paste fills microscopic gaps between the CPU heat spreader and the heat sink, ensuring efficient heat transfer. Without it, there is a significant air gap, which acts as an insulator, causing CPU temperatures to rise dramatically even under light load. CompTIA A+ stresses thermal compound application as a key step in CPU cooling installation.
The scenario indicates that temperatures increased drastically after upgrading to a better heat sink. A higher- performing heat sink should improve temperatures, not worsen them-unless a critical installation step was missed. Missing thermal paste is the most common cause of this symptom and easily explains the sudden overheating.
Decreased CPU voltage would lower temperatures, not raise them. Higher fan RPM increases cooling efficiency, not reduces it. Airflow interruption is possible but less likely in a simple heat sink upgrade scenario unless the technician installed the CPU cooler incorrectly; however, the most direct and common cause described by CompTIA is missing thermal paste.
Thus, D is the correct answer.
질문 # 286
A user reports that a software application functioned as expected the previous day, but this morning, the user is unable to launch the application.
Which of the following describe what the technician should do next?
정답：C
설명：
Identifying changes made to the system is the next step to troubleshoot why an application no longer launches, as recent changes often cause such issues.
질문 # 287
Which of the following will most likely be used in a testing environment to execute unauthorized or experimental code without affecting production systems?
정답：C
설명：
CompTIA A+ strongly emphasizes that virtual machines (VMs) are ideal for testing potentially unsafe software, malware samples, or experimental code because they isolate the environment from the host system.
VMs allow snapshots, cloning, and rollback functionality, which makes them essential in development, QA, and cybersecurity environments where code might be unstable or harmful.
Hybrid cloud refers to infrastructure strategy, not code execution isolation. Load balancers distribute production traffic but have no testing or sandboxing purpose. Application gateways filter traffic but do not provide execution environments.
Virtual machines create a safe sandbox where failure, infection, or corruption is contained. This is covered in the Virtualization and Cloud Computing domain of the CompTIA A+ exam, making VMs the correct tool for executing unauthorized code safely.
질문 # 288
An end user wants to share their cellular internet connection with their laptop. Which of the following technologies should they use?
정답：C
설명：
To share a phone's cellular data connection with a laptop, the user should use a hotspot, also known as mobile hotspot or Wi-Fi tethering. In CompTIA A+ Core 1 terms, this feature allows a smartphone to act like a small wireless router: it takes the phone's mobile data (4G/5G) connection and rebroadcasts it over Wi-Fi so another device (the laptop) can join the wireless network using an SSID and password. This is the most common and straightforward method because laptops universally support Wi-Fi and the connection typically provides better throughput than other tethering methods. Hotspot/tethering settings also commonly allow configuration of security (WPA2/WPA3) and can limit connected devices to reduce unauthorized access and manage data usage.
