                                  質問 # 149
                                  A technician installs VPN client software that has a software bug from the vendor. After the vendor releases an update to the software, the technician attempts to reinstall the software but keeps getting an error message that the network adapter for the VPN already exists. Which of the following should the technician do next to mitigate this issue?

                                  正解：C

                                  解説：
                                  Comprehensive and Detailed Explanation From Exact Extract:
                                  VPN clients often create virtual network adapters. If the software wasn't uninstalled properly or crashed during install, leftover (often hidden) virtual adapters can prevent reinstallation. The proper solution is to delete hidden network adapters using Device Manager (with "Show hidden devices" enabled).
                                  A: OS updates won't fix a leftover driver or adapter issue.
                                  B: Mapping an adapter to the software is not a standard or viable solution.
                                  C: Firmware updates apply to physical adapters, not virtual VPN adapters.

                                  質問 # 150
                                  An end user discovers a virus on their computer. A technician quarantines the computer, scans for viruses, and remediates the infection. Which of the following is the next step the technician should take?

                                  正解：D

                                  解説：
                                  Educating the end user is the next step to help prevent future infections by informing them about safe practices and how to avoid similar threats.


                                  質問 # 151
                                  Independent contractors often work from a business ' s lobby. Although the business has Wi-Fi, contractors often plug in their laptops to Ethernet ports in the lobby. Which of the following should a security engineer do to most efficiently address a potential security concern with this network setup?

                                  正解：D

                                  解説：
                                  Open Ethernet ports in a public-facing area create a direct, high-trust entry point into the internal network.
                                  The most efficient fix is to remove that exposure by disabling the lobby ports and moving untrusted users to a segmented guest network. Quentin Docter explains why disabling unused/unauthorized access points matters:
                                  "Ports on a switch, router, or firewall not in use present an open door for an attacker to enter and should be disabled or disconnected." That directly supports disabling lobby switch ports that shouldn't be available to external users.
                                  He also describes guest network isolation: guests "never need to connect to the organization's servers and internal systems," so a guest SSID should be created that "isolates guest traffic from production traffic." This is exactly what option B accomplishes: it prevents contractors from gaining internal wired access while still providing Internet access through a controlled guest network.
                                  WPA3 (A) only improves Wi-Fi encryption; it doesn't stop wired port access. Monitoring traffic (C) is reactive. Signage (D) is weak administrative control compared to disabling the ports.


                                  質問 # 152
                                  After installing new webcam software, a PC experiences BSOD during videoconference calls. What should the technician do next?

                                  正解：C

                                  解説：
                                  BSOD after driver installation suggests a compatibility issue.Safe Mode allows rollback of driversthat may be causing the crash.
                                  FromTravis Everett - CompTIA A+ All-in-One Exam Guide:
                                  "If a BSOD occurs after a driver update, boot into Safe Mode and roll back to the previous driver version to restore system stability."


                                  質問 # 153
                                  Which of the following operating systems is used to join a domain?

                                  正解：C

                                  解説：
                                  Windows 11 Pro supports domain joining, unlike Windows Home and SE editions, which lack the necessary domain-join functionality.
