CompTIA A+ Certification Exam: Core 2 認定 220-1202 試験問題 (Q309-Q314):

質問 # 309
A user has been adding data to the same spreadsheet for several years. After adding a significant amount of data, they are now unable to open the file. Which of the following should a technician do to resolve the issue?

正解：B

解説：
As spreadsheets grow in size and complexity, they demand more system memory to load and manipulate data. If the file becomes so large that the available RAM is insufficient, the application may fail to open it. Adding more RAM gives the spreadsheet software the resources it needs to load and work with the expanded dataset.


質問 # 310
A security administrator teaches all of an organization ' s staff members to use BitLocker To Go. Which of the following best describes the reason for this training?

正解：D

解説：
BitLocker To Go is a Microsoft encryption feature specifically designed for removable drives such as USB flash drives and external hard drives. It allows users to protect the data on these devices by requiring a password to decrypt the contents, thereby preventing unauthorized access in the event the device is lost or stolen.
A is correct because BitLocker To Go is directly tied to password-protecting removable media.
B and C are unrelated to BitLocker To Go; Secure Boot and VPN encryption are entirely different security layers.
D applies to BitLocker (not BitLocker To Go) and full disk encryption on internal drives using TPM.
Reference:
CompTIA A+ 220-1102 Objective 2.2: Compare and contrast common security measures and tools.
Study Guide Section: Encryption technologies (BitLocker, BitLocker To Go)


質問 # 311
Performance on a user's smartphone is degrading. Applications take a long time to start, and switching between windows also takes a long time. Which of the following diagnostic steps should a mobile technician take first?

正解：D

解説：
Comprehensive and Detailed Explanation From Exact Extract:
Thefirst stepin troubleshooting degraded mobile performance is typically arestart. This clears RAM and stops background processes that might be causing issues.
FromAll-in-One Exam Guide:
"Before taking invasive measures like a factory reset, always restart the device. A reboot clears temporary files and can significantly improve responsiveness."


質問 # 312
A user ' s computer is running slowly. Web pages take several seconds to open, and applications are slow to respond. A technician opens the Windows Task Manager and sees the following:
Disk: 2%
Network: 12%
GPU: 15%
CPU: 70%
Memory: 97%
Which of the following would a technician most likely do to resolve the issue?

正解：A

解説：
Highmemory usage (97%)suggests the system is overloaded with active processes. The technician should close unneeded applications to free up RAM and improve performance.
FromMike Meyers ' Lab Manual:
"When memory usage is near capacity, close all non-essential programs. This can dramatically improve response time without needing hardware upgrades."


質問 # 313
A company's Windows 10 devices have been infected with ransomware, and all files are now encrypted. The executives have decided against paying the ransom. Which of the following actions will achieve full operation without any trace of the ransomware?

正解：B

解説：
The correct answer is C. Perform a clean installation . When ransomware has encrypted files and the organization does not pay the ransom, the priority is to remove all traces of malware and rebuild the system from a trusted state. Quentin Docter's Complete Study Guide explains that in ransomware situations, remediation may not be possible because user files are encrypted. It further states that in cases where no one can be certain what the malware payload has done, the proper remediation might be to sanitize the drive and reinstall the operating system from an image or manually reinstall it. A recovery partition or Windows Recovery Environment repair may leave infected files, settings, persistence mechanisms, or damaged user data behind. Upgrading to Windows 11 does not guarantee malware removal. A clean installation removes the existing compromised OS and provides the best path to full operation, followed by restoring clean data from known-good backups.
