質問 # 484
After moving a user's legacy workstation into a new private office that does not have a LAN connection, the technician is unable to connect to a wireless network. Which of the following is the most likely reason?
- A. Incorrect Wi-Fi channel
- B. Hidden Wi-Fi SSID
- C. Wi-Fi AP replacement
- D. Missing Wi-Fi adapter
正解：D
解説：
The most likely reason is A. Missing Wi-Fi adapter.
A Wi-Fi adapter is a device that allows a computer to connect to a wireless network. A legacy workstation may not have a built-in Wi-Fi adapter, or it may have an outdated or incompatible one. If the workstation does not have a Wi-Fi adapter, it will not be able to detect or access any wireless networks, regardless of the location, signal strength, or configuration of the network.
To fix this issue, the technician can install a Wi-Fi adapter on the workstation, either internally or externally.
An internal Wi-Fi adapter is a card that fits into a slot on the motherboard, while an external Wi-Fi adapter is a device that plugs into a USB port. The technician should choose a Wi-Fi adapter that is compatible with the workstation's operating system, hardware, and wireless standards .
The other options are less likely to be the reason for the issue. A Wi-Fi AP replacement means changing the wireless access point that provides the network connection. This may affect the network name, password, or settings, but it should not prevent the workstation from detecting any wireless networks. A hidden Wi-Fi SSID means that the network name is not broadcasted publicly, but it can still be accessed by entering the name manually. A hidden Wi-Fi SSID may make it harder to find the network, but it should not prevent the workstation from detecting other wireless networks. An incorrect Wi-Fi channel means that the network is using a frequency band that is crowded or interfered by other devices. This may affect the network performance or stability, but it should not prevent the workstation from detecting any wireless networks.

質問 # 486
Which of the following is considered a connectionless protocol?
- A. TCP
- B. HTTPS
- C. UDP
- D. SSH
正解：C
解説：
UDP (User Datagram Protocol) is a connectionless protocol that does not establish a connection before sending or receiving data. UDP simply sends datagrams to the destination without checking if the receiver is ready or not. UDP does not guarantee reliable delivery, error correction, or in-order arrival of the data. UDP is faster and more efficient than connection- oriented protocols for applications that do not require reliability, such as streaming audio or video.
質問 # 487
A technician was called in to look at a user's PC. The user reported the PC was very sluggish.
The HDD light on the PC was constantly on without blinking. The PC itself was slow receiving input and took a very long time to load the OS. The technician also noticed updates had failed.
Which of the following is MOST likely the cause of these issues?
- A. The HDD has no free space.
- B. A RAID disk failed.
- C. The HDD cables need reseating.
- D. The hard disk drivers have been corrupted.
正解：A
解説：
One of the possible reasons for the sluggish performance of the PC could be a lack of free space on the hard disk drive (HDD). When the hard disk is filled to capacity, the operating system and applications are forced to compete for limited space, slowing down performance. The constant light on the HDD and slow input/output performance are signs that the disk is running close to its maximum capacity. The failed updates may also be a result of a lack of disk space as Windows updates require a certain amount of free space to be installed.
質問 # 488
A technician is selecting RAM for a new high-end workstation. The motherboard has eight slots that support DDR5 memory. Which of the following should the technician do to optimize performance?
- A. Increase memory timings.
- B. Utilize all channels.
- C. Use the minimum number of modules.
- D. Increase the virtual RAM.
正解：B
解説：
The best option that the technician should do to optimize performance is D. Utilize all channels. This option means that the technician should install the RAM modules in a way that maximizes the number of memory channels that are used by the motherboard. Memory channels are pathways that connect the memory controller to the RAM modules, and they allow data to be transferred between them. The more memory channels that are used, the higher the memory bandwidth and performance1.
DDR5 memory supports up to eight memory channels per module, which is twice as many as DDR42.
However, not all motherboards can support eight channels per module, and some may only support four or two channels per module. Therefore, the technician should check the motherboard specifications and manual to determine how many memory channels it supports and how to install the RAM modules accordingly.
For example, if the motherboard supports four channels per module, then the technician should install four RAM modules in slots 1, 3, 5, and 7 to use all 16 available channels. If the motherboard supports two channels per module, then the technician should install eight RAM modules in all slots to use all 16 available channels. If the technician installs fewer modules than the number of slots, then some channels will be left unused and the performance will be lower1.

質問 # 493
A large office is eliminating all personal primers for VIP staff members and replacing these devices with one enterprise MFP. Human resources staff members are concerned about printing confidential documents on the new device. Which of the following best addresses this concern?
- A. Secure print
- B. Audit logs
- C. Wi-Fi direct printing
- D. Central printer server
正解：A
解説：
Secure print is the best option to address the concern of printing confidential documents on a shared enterprise multifunction printer (MFP). Secure print requires users to enter a PIN or use an ID card at the printer to release their print jobs. This ensures that documents are only printed when the user is physically present to collect them, preventing sensitive information from being left unattended or viewed by unauthorized individuals. While a central printer server, audit logs, and Wi-Fi direct printing have their own benefits, they do not provide the same level of immediate security for confidential documents as secure print does. A central printer server centralizes management but does not prevent unauthorized viewing. Audit logs provide a record of activity but do not prevent the initial security breach. Wi-Fi direct printing allows for a direct connection to the printer but does not secure the document during printing.

質問 # 498
A technician has noticed that a monitored server is receiving a disk failure notice during startup. When the technician clicks to continue, the machine still seems to startup into Windows but at a much slower speed. The technician looks at the BIOS information and sees the machine utilizes a RAID 5 configuration. Which of the following does the technician MOST likely need to perform?
- A. Replace the failed drivers.
- B. Restart the system.
- C. Reinstall the HDD drivers.
- D. Rebuild The RAID.
正解：D
解説：
The disk failure notice during startup indicates that one or more disks in the RAID array have failed. The machine still seems to startup into Windows but at a much slower speed because the RAID 5 configuration can tolerate one disk failure and still operate, but with reduced performance and reliability. The technician most likely needs to rebuild the RAID, which means replacing the failed disk(s) and restoring the data from the parity information. Reinstalling the HDD drivers will not fix the disk failure. Replacing the failed drivers is not a valid option, as drivers are software, not hardware. Restarting the system will not fix the disk failure either. References: https://www.comptia.org/blog/what-is-raid-0-1-5-6-10
