質問 # 315
A user replaces their PC power supply and connects it to the components, but the PC fails to start. What is the most likely cause?
正解：A
解説：
Modern motherboards require both the 24-pin ATX connector and a 4-pin or 8-pin CPU power connector. If the CPU power connector is not attached, the motherboard will receive power but the system will not boot. CompTIA A+ specifically lists this as a common mistake after replacing a power supply.
Insufficient wattage may cause instability, but usually the system still attempts to start. RAM does not prevent power-on if missing; instead, the system produces beep codes. Redundant PSUs are used in servers, not standard desktops.
Therefore, the missing CPU power connector is the most likely cause, and this scenario reflects typical troubleshooting steps outlined in A+ hardware diagnostics.
質問 # 316
A user is testing a new OS that is contained on a USB drive. The user wants the new OS to load automatically when the computer is turned on. Which of the following should the user configure?
正解：C
解説：
To boot from a USB drive, the user must configure the boot order in the system BIOS/UEFI to prioritize the USB device. This setting tells the computer to load the operating system from the USB device on startup.
質問 # 317
An administrator is helping a new employee configure email on a smartphone. The employee also needs access to a shared mailbox. Which is the best email client for this situation?
正解：D
解説：
A corporate-provided email client is designed to integrate with enterprise services such as shared mailboxes, MDM policies, and enterprise authentication. CompTIA A+ states that corporate clients support additional management features, secure authentication protocols (such as OAuth or Kerberos), and policy-enforced access control essential for accessing shared or departmental mailboxes.
Open-source clients (Option A) may lack compatibility with enterprise environments. Built-in smartphone clients (Option B) often don't support complex mailbox structures such as shared mailboxes. Employee- preferred apps (Option D) are discouraged because they may not meet security requirements.
Corporate clients ensure full compatibility with organizational mail servers, shared folders, calendars, and enterprise security features, making corporate email clients the correct choice according to CompTIA's mobile device email configuration standards.
質問 # 318
A user goes to their office and forgets their laptop charger. After borrowing a charger, the user notices that the battery is charging slowly. Which of the following steps should a technician take first to charge the battery normally?
正解：B
解説：
Using a different power supply ensures the charger provides the correct wattage and amperage required by the laptop, which is necessary for the battery to charge at a normal rate.
質問 # 319
Which of the following is used to implement PoE?
正解：B
解説：
The correct answer is D. Injector.
Power over Ethernet (PoE) allows network cables to carry electrical power to devices such as wireless access points, IP cameras, and VoIP phones, eliminating the need for separate power supplies. According to the CompTIA A+ Core 1 220-1201 objectives under Networking, PoE can be implemented in the following ways:
* PoE-enabled switches: Switches that can supply power directly over the Ethernet ports.
* PoE injectors: Devices that add power to an existing Ethernet connection when the switch or router does not provide PoE.
Why the other options are incorrect:
* A. Modem: A modem connects a network to the Internet but does not provide PoE functionality.
* B. Range extender: Extends the range of a wireless network; does not supply power over Ethernet.
* C. Media converter: Converts one type of network media to another (e.g., fiber to copper) but does not implement PoE.
Therefore, when a switch does not natively provide PoE, a PoE injector is the standard solution to add power to the Ethernet line.
