最新的 A+ 220-1101 免費考試真題 (Q566-Q571):

問題 #566
Which of the following network devices operates as a bridge function?

答案：A

解題說明：
A media converter is a network device that operates as a bridge function, which means it connects two different types of network media, such as copper and fiber optic cables, and converts signals between them. This allows network devices that use different media types to communicate with each other over long distances or in different environments, without requiring major changes or upgrades to the existing network infrastructure.

問題 #567
A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the cable mediums would be the MOST cost effective without sacrificing system performance?

答案：D

解題說明：
Electromagnetic interference (EMI) is unwanted noise or interference in an electrical path or circuit caused by an outside source. Hence shielded Cat 6 is better


問題 #568
A user dropped a laptop while it was turned on. The hard drive now makes a clicking sound, and the laptop will not start up. Which of the following most likely explains this situation?

答案：D

解題說明：
A clicking hard drive is usually a sign of a mechanical failure, where the read/write heads are not functioning properly or the platters are scratched or broken. This can be caused by physical shock, such as dropping the laptop while it was turned on. A damaged hard drive may not be able to boot up the operating system or access the data stored on it. This is a serious problem that requires data recovery and hard drive replacement.


問題 #569
A user reports a tablet restarts on its own every five to ten minutes. In addition, the tablet has intermittent issues with charging. The technician gives the user a new power adapter and charging cable, and the technician also tries resetting the OS. but the issue persists. Which of the following is the MOST likely cause of the issue?

答案：C

解題說明：
A faulty battery could cause a tablet to restart on its own and have intermittent issues with charging. Water damage could also cause these symptoms, but it is not the most likely cause unless there is evidence of liquid exposure. Incorrect OS version could cause compatibility or performance issues, but not charging problems. Damaged charging port could prevent the tablet from charging, but not cause it to restart randomly.


問題 #570
A technician is installing a power supply in a workstation that contains a high-end graphics card, a 3GHz processor, and two cooling fans. Which of the following specifications should the technician verify before installing the new power supply?

答案：B

解題說明：
The most important specification that the technician should verify before installing the new power supply is A) The wattage.
The wattage of a power supply is the measure of how much power it can deliver to the components of a computer. The wattage of a power supply should match or exceed the total power consumption of the computer, otherwise the computer may not function properly or may experience instability, overheating, or damage12.
To calculate the total power consumption of a computer, the technician can use a tool such as a power supply calculator, which can estimate the required wattage based on the components and features of the computer. For example, using one of the web search results3, I entered the following information:
* CPU: 3 GHz processor
* GPU: High-end graphics card
* RAM: 16 GB DDR4
* SSD: 1 x 500 GB
* HDD: 1 x 1 TB
* Optical Drive: 1 x DVD-RW
* Fans: 2 x 120 mm
* Other Devices: Keyboard, Mouse, Monitor
The tool estimated that the recommended PSU wattage for this computer is 550 W. Therefore, the technician should verify that the new power supply has at least this wattage before installing it.
The chassis ventilation, the motherboard's firmware, and the cables' color coding are not as important as the wattage for installing a new power supply. The chassis ventilation is related to the airflow and cooling of the computer, which can affect the performance and lifespan of the components. The motherboard's firmware is the software that controls the basic functions of the motherboard, such as booting, input/output, and memory management. The cables' color coding is a standard way of identifying the function and polarity of the wires in a power supply. However, none of these specifications are directly related to the power delivery or compatibility of the new power supply.
