                                  質問 # 241
                                  Which of the following is provided to a user during MFA?

                                  正解：D

                                  解説：
                                  Time-based One-Time Passwords are provided to users during multifactor authentication as a temporary, dynamically generated code. This code serves as an additional authentication factor beyond a username and password, enhancing security by requiring something the user has in addition to something they know.

                                  A user ' s new laptop, which was advertised as gaming-ready, is performing slowly when the user is playing a modern game. However, when the user is playing a less resource-demanding game, the user does not see any lag. Which of the following should a technician do to resolve the issue?

                                  正解：B

                                  解説：
                                  This is a classic symptom of graphics performance limitations: modern games stress GPU/VRAM far more than older or lightweight titles. The All-in-One guide explains that "graphically demanding applications...
                                  state specific graphics requirements," and highlights that CompTIA focuses on "dedicated graphics cards versus integrated ones." It further clarifies that integrated GPUs are typically less powerful than dedicated GPUs and that demanding software (including games) often assumes dedicated graphics, with VRAM requirements frequently included.
                                  On many "gaming-ready" laptops, the system may have both integrated and discrete graphics, and performance issues occur if the game runs on the integrated GPU instead of the discrete GPU. Selecting dedicated graphics (for the application or globally, depending on the platform) forces the workload onto the more capable GPU and typically resolves lag. Overclocking RAM is not the first-line fix and adds instability risk, NIC teaming is irrelevant to local rendering performance, and hyperthreading helps some CPU workloads but won't solve a GPU-bound modern game. Therefore, Select dedicated graphics (C) is best.

                                  Which of the following types of malware would most likely be detected when observing unusually high CPU usage?

                                  正解：A

                                  解説：
                                  The correct answer is C. Cryptominer . Cryptominer malware secretly uses a victim computer's processing resources to mine cryptocurrency for an attacker. Because cryptocurrency mining requires heavy computation, this malware commonly causes unusually high CPU or GPU usage. The All-in- One Exam Guide explains that cryptominers take control of a computer's hardware resources to mine cryptocurrency and that a telltale sign may be inexplicably high GPU or CPU utilization. The Mike Meyers/Mark Soper material states the same concept: cryptominer malware uses the target system's CPU or GPU, and one sign of infection is unexplained high resource usage. A keylogger records keystrokes, a Trojan disguises itself as legitimate software while performing malicious actions, and a rootkit hides itself using low-level OS access. Those malware types can be dangerous, but high CPU usage most strongly points to a cryptominer.

                                  A user wants to use a new laptop to play audio and video to an office projector, but the laptop does not have VGA or HDMI. Which of the following adapters should the user buy?

                                  正解：B

                                  解説：
                                  Modern laptops without VGA or HDMI typically use USB-C for video output, which supports DisplayPort over USB-C. Using a USB-C to HDMI adapter enables both audio and video transmission to the projector.
