                      問題 #42
                      An administrator is configuring a bare-metal server to host several virtual machines. Which of the following should the administrator use to complete this task?

                      答案:E

                      解題說明:
                      A hypervisor allows a bare-metal server to host multiple virtual machines by abstracting the underlying hardware and allocating resources to each virtual instance.


                      問題 #43
                      After a technician installs a new motherboard, the computer will not start and fails POST. The technician verifies the power supply is functioning as expected, and the CPU is installed correctly.
                      Which of the following steps should the technician complete next?

                      答案:C

                      解題說明:
                      A common reason for a POST failure after a motherboard installation is improperly seated RAM.
                      The system requires working memory to successfully complete POST. Reseating (removing and reinserting) the RAM ensures it's making proper contact with the motherboard.


                      問題 #44
                      Laura, a customer, has instructed you to configure her home office wireless access point.
                      She plans to use the wireless network for finances and has requested that the network be setup with the highest encryption possible.
                      Additionally, Laura knows that her neighbors have wireless networks and wants to ensure that her network is not being interfered with by the other networks.
                      She requests that the default settings be changed to the following.
                      Wireless Name: HomeWiFi
                      Shared Key: CompTIA
                      Router Password: Secure$1
                      Finally, Laura wants to ensure that only her laptop and Smartphone can connect to the network.
                      Laptop: IP Address 192.168.1.100
                      Hardware Address: 00:0A:BF:03:C4:54
                      Smartphone: IP Address 192.168.1.101
                      Hardware Address: 09:2C:D0:22:3F:11
                      INSTRUCTIONS
                      Configure Laura's wireless network using the network adapter window.
                      If at any time you would like to bring back the initial state of the situation, please click the Reset All button.

                      問題 #45
                      The power supply for a user's gaming computer fails. The user buys a replacement online. The user connects the power supply to the motherboard, the graphics card, and the SSDs, but the computer fails to start and displays a critical error. Which of the following is the most likely cause?

                      答案:D

                      解題說明:
                      Modern motherboards require two separate power connections from the power supply: the 24-pin ATX connector for general motherboard power and a 4-pin or 8-pin CPU (EPS) connector dedicated to powering the processor. According to CompTIA Core 1 (220-1201) power supply installation and troubleshooting guidelines, failing to connect the CPU power connector commonly results in a system that does not boot and may display a critical or CPU-related error.
                      In this scenario, the user connected power to the motherboard, graphics card, and storage devices, but the system fails to start. This strongly indicates that the CPU power connector was overlooked, which is a frequent mistake during PSU replacement. Without this connection, the processor cannot initialize, preventing POST.
                      Insufficient wattage typically causes instability, shutdowns, or reboots under load rather than immediate failure with a critical error. RAM upgrades are unrelated to PSU replacement, and redundant power supplies are used in enterprise systems, not standard gaming PCs.
                      CompTIA emphasizes verifying all required PSU connectors, especially the CPU power connector, as a critical troubleshooting step when a system will not power on after a PSU replacement.


                      問題 #46
                      An IT specialist is setting up a new, custom computer. The specialist wants to minimize the number of power cables to keep the internal components organized and uncluttered. Which of the following power supply types should the specialist use?

                      答案:C

                      解題說明:
                      A modular power supply allows the user to connect only the cables needed, reducing clutter and improving organization inside the case.
                      From CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 - Power supplies:
