                      최신 A+ 220-1201 무료샘플문제 (Q248-Q253):

                      질문 # 248
                      Which storage device is best suited for a high-performance gaming laptop requiring fast data access?

                      정답：C

                      설명：
                      Gaming laptops prioritize speed, low latency, fast read/write times, and quick loading. CompTIA A+ explains that NVMe M.2 SSDs provide the fastest consumer storage available due to their use of the PCIe bus, which delivers significantly higher performance compared to SATA-based drives.
                      HDDs (Options A and C) are mechanical and have slow seek times, making them unsuitable for high- performance gaming. SAS SSDs (Option D) are enterprise-grade, rarely used in laptops, and require SAS controllers not found in consumer systems.
                      Thus, a 512GB NVMe M.2 SSD offers the best performance, fastest boot times, rapid texture loading, and optimal gaming responsiveness fully aligning with A+ hardware performance recommendations.


                      질문 # 249
                      A user cannot access the internet from a corporate laptop. All other employees can. The technician reviews the laptop's configuration:
                      IP Address: 169.254.2.162
                      Which explains the reason the user cannot access the internet?

                      정답：B

                      설명：
                      An IP address beginning with 169.254.x.x is an APIPA address (Automatic Private IP Addressing). CompTIA A+ explains that APIPA is assigned automatically by Windows when the NIC cannot reach a DHCP server. This indicates the laptop requested an IP lease but never received one.
                      APIPA addresses allow only local subnet communication and cannot access the internet, because no default gateway, DNS, or valid subnet configuration is provided. Since all other employees can access the internet, the DHCP server is functioning generally, but it is not delivering an address to this specific laptop-possibly due to cable issues, Wi-Fi authentication failure, DHCP scope exhaustion, or NIC misconfiguration.
                      A subnet mask misconfiguration (A) would still show a normal IP, not APIPA. IPv6-only configuration (C) would not produce a 169.254 address. An outdated NIC driver (B) could cause network instability but does not directly generate APIPA.
                      Thus, the root cause is that the DHCP server did not assign an IP address.


                      질문 # 250
                      An end user reports that their laptop has a blank screen. A technician observes the keyboard lights are on, and the fan is running. Which of the following should the technician do next?

                      정답：D

                      설명：
                      When a laptop powers on but the screen is blank, the quickest way to isolate the problem is to connect to an external monitor. This helps determine if the issue is with the laptop display or with the graphics subsystem.


                      질문 # 251
                      A technician needs to prepare a conference room for a meeting. The technician connects the laptop to the LCD projector and audio system, and then verifies the connectivity of each device. The meeting begins, but the visual presentation suddenly cuts off 30 minutes later. The audio continues to play without interruption.
                      The technician brings in a backup laptop and connects it to the projector. The meeting continues without issue for 15 minutes until the presentation suddenly cuts off again. Which of the following should the technician do to resolve this issue?

                      정답：A

                      설명：
                      Overheating is a common cause of projectors shutting down after extended use. A clogged air filter can cause overheating, resulting in intermittent shutdowns.

                      질문 # 252
                      A user would like to connect a laptop to a monitor, keyboard, and mouse when in the office. The user prefers to use as few cables as possible. Which of the following would best achieve that goal?

                      정답：C

                      설명：
                      A docking station allows users to connect multiple peripherals (monitor, keyboard, mouse, etc.) to a laptop with a single connection, reducing cable clutter and improving convenience.
