質問 # 95
A technician is creating a new RAID array for a customer After interviewing the customer, the technician decides to implement a RAID array of striping without parity. Which of the following reasons would lead the technician to choose striping without parity instead of striping with parity?
- A. Uptime is the customer's biggest concern
- B. Redundancy and speed are equally important
- C. Speed is the most important consideration.
- D. Available storage space needs to be maximized
正解：C
解説：
Explanation
Speed is the most important consideration. Striping without parity, also known as RAID 0, is a RAID configuration that splits data across multiple disks without any redundancy. This improves the performance of read and write operations, as multiple disks can work in parallel. However, this also increases the risk of data loss, as any disk failure will result in losing all data on the array. Therefore, striping without parity is suitable for situations where speed is prioritized over reliability. According to the CompTIA Core1 objectives, one of the advantages of RAID 0 is increased speed. A research paper on RAID performance also confirms that RAID 0 has the highest throughput among all RAID levels.

質問 # 106
A user with an older laptop is unable to connect to the office network after new access points were installed. The user confirms that from home the laptop can connect wirelessly to the network. Which of the following should the user to do to quickly resolve the issue?
- A. Install a new Bluetooth card.
- B. Connect a new USB adapter.
- C. Connect a new biometric device.
- D. Install a new SSD
正解：B
解説：
A USB adapter is a device that can plug into a USB port on a laptop and provide wireless connectivity to a network. A USB adapter can support different wireless standards, such as 802.11a, 802.11b, 802.11g, 802.11n, or 802.11ac. A USB adapter can also support different wireless frequencies, such as 2.4 GHz or 5 GHz.
In this case, the user with an older laptop may not be able to connect to the office network after new access points were installed because the laptop's built-in wireless card does not support the same wireless standard or frequency as the new access points. For example, if the new access points use 802.11ac and 5 GHz, and the laptop's wireless card only supports 802.11g and 2.4 GHz, the laptop will not be able to communicate with the access points.
To quickly resolve this issue, the user should connect a new USB adapter that supports the same wireless standard and frequency as the new access points. This way, the user can bypass the laptop's wireless card and use the USB adapter to connect to the office network wirelessly.
質問 # 107
A technician is setting up a new laptop for a user who wants to be able to quickly pack up the laptop and leave if needed. The user has the following accessories:
- USB badge reader
- USB badge printer
- USB signature pad
- 3.5mm headset
- HDMI external monitor
- Mouse
Which of the following is the best way to meet the user's requirement?
- A. Connect everything to a compatible docking station.
- B. Provide the user with a second laptop.
- C. Directly connect all accessories to the laptop.
- D. Provide the user with a USB hub.
正解：A
解説：
A docking station is a device that allows a laptop to connect to multiple peripherals and accessories with a single connection. A docking station usually has ports for USB, HDMI, audio, Ethernet, and power, as well as slots for expansion cards. A docking station can enhance the functionality and convenience of a laptop by providing a desktop-like experience. A compatible docking station is one that matches the laptop's model, brand, and connector type. A port replicator is a simpler device that only replicates the ports of the laptop, such as USB and HDMI, without providing additional features or power. A port replicator can also allow a laptop to connect to multiple peripherals and accessories with a single connection, but it does not offer the same benefits as a docking station.
質問 # 108
The owner of a restaurant reports that wireless network connections are lost intermittently throughout the day.
Which of the following steps should a technician take to troubleshoot the issue? (Select TWO).
- A. Schedule timed router reboots throughout the day.
- B. Identify the location of devices that utilize 2.4GHz.
- C. Test to see if the copper electrical Wires are causing interference.
- D. Check to see if the phones are IJTP or STP lines.
- E. Verify T568B is being used in the wiring closet patch panel.
- F. Map all of the wireless signals in the restaurant.
正解：B、F
解説：
The correct answers are A. Identify the location of devices that utilize 2.4GHz and D. Map all of the wireless signals in the restaurant. In order to troubleshoot the issue, the technician should first identify the location of devices that utilize the 2.4GHz frequency, as this can cause interference with the wireless signal.
Additionally, the technician should map all of the wireless signals in the restaurant in order to identify any potential sources of interference. Checking to see if the phones are IJTP or STP lines, testing to see if the copper electrical wires are causing interference, verifying T568B is being used in the wiring closet patch panel, and scheduling timed router reboots throughout the day are not necessary steps for troubleshooting this issue.
質問 # 109
A technician recently reinstalled a previously virtualized application directly to a user's computer.
Now, the application is not launching. Which of the following did the technician most likely do to cause this issue?
- A. Installed the wrong license type.
- B. Reset the user's application virtualization session.
- C. Installed the software on the base operating system.
- D. Installed the application with administrator rights.
正解：C
解説：
If an application was previously running in a virtualized environment and is not launching after being installed directly on the base operating system, it's possible that the technician did not account for dependencies or configurations specific to the virtualized environment that are not present or are incompatible with the base operating system. This mismatch can prevent the application from launching properly.
質問 # 110
A technician is relocating a router access point farther away from the modem to optimize signal coverage for a SOHO client. Which of the following will the technician most likely use to complete the relocation? (Select two).
- A. Wi-Fi analyzer
- B. Network tap
- C. Punchdown tool
- D. Clamp-style wire stripper
- E. Crimper
- F. Loopback plug
正解：A、E
解説：
A crimper is a tool that is used to attach connectors to network cables, such as RJ-45 or RJ-11. A technician might need a crimper to create a longer cable for the router access point or to replace a damaged connector.
A Wi-Fi analyzer is a software or hardware tool that can scan and measure the wireless signal strength, interference, channel usage, and security of a Wi-Fi network. A technician might need a Wi-Fi analyzer to find the optimal location and configuration for the router access point to improve the signal coverage for the SOHO client.

A Wi-Fi mesh network has been optimized to eliminate poor coverage areas, yet users still experience decreased bandwidth and connectivity issues. Which of the following actions should the technician take NEXT?
- A. Use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.
- B. Turn off broadcasting of the SSID on the mesh network so that other networks cannot see it.
- C. Use the signal strength indicator on a mobile device to roam the coverage area and generate a heat map to isolate zones with weak signals.
- D. Relocate any large, dense, solid, and metal objects, such as mirrors and file cabinets, in the mesh network coverage area to the perimeter so that wireless reflections, absorptions, and occlusions are minimized.
正解：A
解説：
If users are experiencing decreased bandwidth and connectivity issues in a Wi-Fi mesh network, the technician should use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.
