                                  CompTIA A+ Certification Exam: Core 2 認定 220-1202 試験問題 (Q296-Q301):

                                  質問 # 296
                                  A user ' s machine is infected with malware that the user ' s existing security software did not detect. Which of the following best explains the reason the infection was undetected?

                                  正解:D

                                  解説:
                                  Antivirus/antimalware detection depends heavily on its definitions/signatures. If those are outdated, new malware variants may not be recognized. Quentin Docter explains that the "definitions database" is a core antivirus component and that its effectiveness depends on "the frequency of updates and the comprehensiveness of the database signatures." He adds that new signatures are discovered frequently and added to the database, meaning stale definitions leave gaps.
                                  Docter is also explicit that security software "is not perfect" and that malware may get around it, "especially a new threat (and especially if you haven't updated your definitions lately)." That statement directly matches this scenario: the software exists, but it failed to detect the infection-most likely because the detection data wasn't current.
                                  The other answers don't fit as well: folder permissions and user permissions can limit what malware can change, but they don't explain why security software didn't detect it. Port security relates to network access control, not local signature detection. Therefore, Outdated definitions (B) is the best explanation.


                                  質問 # 297
                                  Which of the following is used in addition to a password to implement MFA?

                                  正解:B

                                  解説:
                                  Multi-Factor Authentication (MFA) requires at least two different types of authentication factors:
                                  Something you know (e.g., password or PIN)
                                  Something you have (e.g., smartphone or hardware token)
                                  Something you are (e.g., fingerprint or facial recognition)
                                  Option A, sending a code to the user's phone, is an example of " something you have " - a physical device that receives a one-time passcode. Combined with a password, this forms a proper MFA implementation.
                                  B). Date of birth is another knowledge-based factor (like a password), not a second factor type.
                                  C). Solving a math problem is not a recognized authentication factor.
                                  D). A PIN is also " something you know " and does not count as a distinct MFA factor when paired with a password.

                                  質問 # 298
                                  A help desk technician is setting up speech recognition on a Windows system. Which of the following settings should the technician use?

                                  正解:C

                                  解説:
                                  Windows places speech recognition and other accessibility features under the Ease of Access settings. From there, you can configure Speech options - including enabling Windows Speech Recognition and adjusting its settings - so that users relying on voice input can operate the system effectively.


                                  質問 # 299
                                  Which of the following is a Linux command that is used for administrative purposes?

                                  正解:B

                                  解説:
                                  Comprehensive and Detailed Explanation From Exact Extract:
                                  The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.
                                  A: runas is a Windows command for executing a program under another user's context.
                                  B: cmcl is not a valid Linux or administrative command.
                                  C: net user is a Windows command for managing local user accounts.

                                  質問 # 300
                                  An administrator must configure a server that prioritizes data availability. Because the server will be accessed by many users, the administrator must also consider performance. Which of the following RAID levels best meets these requirements within a single array?

                                  正解:C

                                  解説:
                                  RAID 10 combines mirroring and striping, providing high data availability through redundancy and improved performance through parallel read/write operations, making it ideal for environments with many users and high access demands.


                                  質問 # 301
