CompTIA Certification Practice Exam Test! Trivia Quiz

USB-C is the correct answer because it is a reversible connector, meaning it can be plugged into a device both right-side up and upside down. This makes it more convenient and user-friendly compared to other connector types such as Micro-USB, Mini-USB, and regular USB, which can only be plugged in one way.

After replacing the physical display, if the laptop is showing images correctly but the screen no longer responds to touch, the most likely component that needs to be replaced is the digitizer. The digitizer is responsible for translating touch input into digital signals, allowing the device to recognize and respond to touch gestures. If the screen is not responding to touch after replacing the display, it indicates a problem with the digitizer, which may need to be replaced.

The technician should use a cable tester to continue troubleshooting the connection. A cable tester is a tool that can test for continuity and identify any faults or issues in the network cable. It can help determine if there are any breaks, shorts, or miswires in the cable, which could be causing the connectivity problem. By using a cable tester, the technician can quickly identify and resolve any issues with the network cable, allowing the end user to connect to the network successfully.

The technician should check the video resolution. The issue of disproportionate and illegible desktop icons on the projector screen suggests that the resolution settings may not be compatible with the projector. Adjusting the video resolution to match the projector's capabilities should resolve the problem and display the icons properly.

A cable tester is the appropriate tool to use in this situation because it can help the technician determine if there is an issue with the network cable. By connecting the cable to the tester, the technician can check for continuity, shorts, and other potential problems that may be causing the connection issue. This tool can help narrow down the source of the problem and guide further troubleshooting steps.

Connecting the printer to the company wireless network will resolve the issue because the user has already installed all necessary software for the printer on the computer and connected it to the guest wireless network. However, since nothing happens when attempting to print, it suggests that the guest wireless network may not have the necessary permissions or settings to allow printing. By connecting the printer to the company wireless network, which is likely to have the appropriate permissions and settings for printing, the user will be able to successfully print.

Fiber optic cables would be the best solution for increasing network bandwidth to 1Gbps between two office buildings that are 0.5mi apart. Fiber optic cables have a much higher bandwidth capacity compared to other options like Cat 6, Plenum, or Coaxial cables. They are capable of transmitting data at high speeds over long distances without any loss of signal quality. Therefore, using fiber optic cables would ensure a reliable and efficient network connection between the two office buildings.

The technician is troubleshooting a network speed issue with the user's mobile device. Long-term evolution (LTE) is a technology used for high-speed wireless communication for mobile devices. It is a standard for 4G wireless broadband that provides faster data transfer rates and improved network capacity. By calling the user's cellular provider, the technician can troubleshoot and resolve any network speed issues related to LTE technology.

The technician should use a punchdown tool to resolve the problem. A punchdown tool is used to secure wires into a patch panel or keystone jack. Since there are wires pulled out of the patch panel, using a punchdown tool will allow the technician to properly reinsert and secure the wires, restoring connectivity. Wire strippers are used to remove the protective coating from wires, but they are not needed in this situation. A tone generator is used to trace and identify cables, which is not relevant to the issue at hand. A crimper is used to attach connectors to the ends of cables, which is also not necessary in this case.

A multimeter is the most appropriate tool to use in order to verify if the data racks have been properly grounded. A multimeter is a versatile device that can measure various electrical parameters such as voltage, current, and resistance. By using the multimeter, the technician can check the continuity of the grounding connections and ensure that there is a proper electrical path between the racks and the ground. This will help in addressing the concern of protecting the data cabling and equipment by ensuring that any potential electrical faults are properly grounded and do not pose a risk to the equipment.

The flickering issue is specific to the projector's image, as the laptop display does not have the same problem. This suggests that the issue may be related to the connection between the laptop and the projector. Therefore, the next logical step for the technician would be to check the connectivity of the VGA cable, as a loose or faulty connection could be causing the flickering problem.

The technician should use a punchdown tool to resolve the problem. The wires pulled out of the patch panel need to be reconnected properly, and a punchdown tool is used to secure the wires into the appropriate slots on the patch panel. This will ensure proper connectivity and resolve the user's inability to connect to any resources.

The technician should enable 802.11a on the wireless SOHO router to ensure wireless connectivity to the printer. 802.11a operates on the 5GHz frequency band, which is the same frequency band supported by the printer. This will allow the printer and the router to communicate effectively and take advantage of the printer's maximum throughput of 54Mbps.

RAID 10 with 5400rpm 6TB drives is the preferred choice because it offers a combination of redundancy and performance. RAID 10 provides both mirroring and striping, which means data is duplicated across multiple drives for fault tolerance and improved read and write speeds. The 5400rpm drives may have a slower rotational speed compared to the other options, but the RAID 10 configuration compensates for this by providing better overall performance and data protection. Additionally, the 6TB capacity is still substantial and should be sufficient for most storage needs.

The correct answer is that there is a problem with a router in the office. This is because a router is responsible for routing network traffic between different networks, and if there is a problem with the router, it can cause connectivity issues for the users in the office. This can result in the users not being able to access the internet or communicate with other devices on the network.

The technician would most likely select RAID 1 with 10000 RPM 8TB drives because RAID 1 provides fault tolerance by mirroring data across multiple drives, minimizing the risk of data loss. Additionally, the 10000 RPM drives offer higher performance compared to the other options, ensuring the applications on the server can run smoothly. The 8TB capacity meets the requirement for over 10TB storage while still minimizing the number of failure points.
