질문 # 517
Which of the following cable types can be used to transfer data and video?
정답：D
설명：
USB-Cis a versatile connector capable oftransmitting data, video, audio, and power. With standards likeDisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more - all through one cable.
Option B (HDMI):Supports video and audio but not general data transfer.
Option C (DisplayPort):Similar to HDMI - supports video/audio but not general file transfer.
Option D (VGA):Legacy analog video only - no data or audio support.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 3.1: Identify common connector types.
질문 # 518
A technician replaced a failed PSU on a high-end workstation PC. Now, the PC fails to POST and does not stay turned on for more than five seconds. Which of the following power connections was most likely forgotten during installation?
정답：B
설명：
The issue described suggests the 12V CPU power connector was likely forgotten during installation. The 12V power rail is essential for the operation of high-end workstation components, including the CPU. Without the 12V connection, the system will fail to POST and may power off shortly after being turned on.
Why 12V?
The 12V connector is critical for providing power to the CPU via the motherboard. Modern CPUs require a dedicated power source from the PSU, usually supplied through the 4-pin or 8-pin EPS12V connector.
If this connection is omitted, the motherboard will not receive adequate power for the CPU to function, resulting in the system failing to POST or shutting down after a brief period.
질문 # 519
A user receives an error when installing a new email app on their phone. Technician verifies OS is updated and app is supported. What should the technician check next?
정답：B
설명：
When an application fails to install on a smartphone despite being supported by the OS and device type, CompTIA A+ stresses that the most common cause is insufficient storage. Mobile devices require not only space for the app itself but also additional temporary space for the installation process, cached data, and updates. If internal storage is nearly full, the app store will display installation errors-even if the OS and hardware meet requirements.
Battery health has no impact on app installation. A SIM card is unrelated to installing local applications-it only affects cellular connectivity. Processor architecture issues would have been caught during compatibility checking, but the technician already verified the device supports the application.
Therefore, after confirming compatibility, the next logical step is to check available storage space. If storage is low, deleting unused apps, clearing cached data, or transferring media to cloud storage or an SD card typically resolves the installation issue.
Thus, Option A: Storage is the correct answer.
질문 # 520
A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage. Which of the following should the technician do to resolve the issue? (Choose two.)
정답：B,C
설명：
Repair the backup power source. Ensuring the UPS actually holds power through outages prevents the PC from abruptly losing all power, which contributes to time resets.
Replace the CMOS battery. A fresh CMOS battery maintains the BIOS clock when the system is shut down or loses power.
질문 # 521
Marketing department users report network performance degradation in the morning and early afternoon, but sales and customer service department users do not report any issues. All structured cabling is Cat 5e. All departments are connected to a core switch. The running network configuration shows the following:
Which of the following is the most likely cause of the performance issues?
정답：C
설명：
From the configuration, the Sales and Customer Service ports are hard-set to full duplex, 1000 Mbps, while the Marketing interface (GigabitEthernet0/3) is set to duplex auto and speed auto.
CompTIA A+ explains that mismatched or lower-negotiated speeds and duplex settings can cause noticeable network slowdowns, collisions, and retransmissions--especially at busy times of the day when utilization is high.
Because all cabling is Cat 5e, it fully supports Gigabit Ethernet, so the cabling is not the limiting factor. The IP addresses are all in the same subnet (192.168.1.0/24) and formatted correctly, so there is no subnet or addressing problem. That rules out options A and C.
With speed auto, the Marketing port may be negotiating only 10/100 Mbps, or even a duplex mismatch (e.g., half duplex vs full). This would severely limit throughput compared to the gigabit links used by the other departments. In peak periods, that slower link would become congested first, which matches the users' reports of performance degradation only in Marketing.
Therefore, the most likely cause is that the Marketing interface is operating at 10/100 instead of
1000 Mbps, making option D correct.
