                                  質問 # 186
                                  A user takes an iOS-based smartphone to a repair shop due to performance issues. The technician observes:
                                  Battery charge: 25%
                                  Battery health: 90%
                                  Hotspot: On
                                  Used space: 63.76GB / 64GB
                                  Which of the following is the most likely cause of the performance issue?

                                  正解：E

                                  解説：
                                  Running atnear full storage capacitysignificantly slows down smartphones. iOS in particular requires space for caching and temporary files. Performance improves when storage is cleared.

                                  "Lack of free space causes mobile operating systems to struggle with temp files and updates. Performance improves significantly with adequate storage."


                                  質問 # 187
                                  Which of the following is used to implement PoE?

                                  質問 # 188
                                  A customer's computer does not have an active connection to the network. A technician goes through a few troubleshooting steps but is unable to resolve the issue. The technician has exhausted their knowledge. The customer expresses frustration at the time taken to resolve this issue. Which of the following should the technician do?

                                  正解：A

                                  解説：
                                  When you've exhausted your troubleshooting expertise and the customer is frustrated, the appropriate next step is to escalate the ticket to a more experienced technician or specialized team. At the same time, communicate clearly to the customer what you're doing and what they can expect next. This maintains transparency, manages expectations, and ensures the issue is resolved as quickly as possible.


                                  質問 # 189
                                  A help desk team was alerted that a company-owned cell phone has an unrecognized password-cracking application. Which of the following should the help desk team do to prevent further unauthorized installations from occurring?

                                  正解：D

                                  解説：
                                  Mobile Device Management (MDM) is used to control, monitor, and enforce policies on mobile devices. It allows IT teams to restrict app installations, push approved apps, and monitor device compliance. Deploying MDM would prevent unauthorized applications, such as password crackers, from being installed on company- managed devices.
                                  A). Group Policy is for managing Windows environments and not applicable to smartphones.
                                  B). PAM (Privileged Access Management) controls administrative access, not app installation.
                                  C). Anti-malware can help detect malicious apps but doesn't prevent their installation proactively.
