CompTIA A+ Certification Exam: Core 2 認定 220-1202 試験問題 (Q151-Q156):

質問 # 151
A user is renaming a .txt file to a .xml file. After renaming the file, Windows Explorer shows the filename as Document....xml. However, the document properties show the type of file as Text Document (.txt). Which of the following controls enables the user to correctly change the file type?

A. Hide extensions
B. Personalization
C. Indexing options
D. Format command

正解：A

解説：
This issue happens when Windows is hiding known file extensions. If extensions are hidden, the user may only be changing the visible name (for example, changing "Document" to "Document.xml"), while the real filename remains something like Document.xml.txt. Windows Explorer then displays "Document.xml," but file properties still show the true type as Text Document (.txt) because the actual extension at the end is still .
txt, and Windows determines file type by that extension. The fix is to show file extensions by turning off the
"hide extensions" behavior-i.e., uncheck "Hide extensions for known file types" in File Explorer Options
/View settings. Quentin Docter specifically calls out that "Hide Extensions For Known File Types" is commonly changed because seeing extensions is "really handy," and shows steps to deselect "Hide File Extensions For Known File Types." The All-in-One guide and Mike Meyers' Lab Manual both reinforce that you toggle extensions by deselecting "Hide extensions for known file types." References: Quentin Docter - CompTIA A+ Complete Study Guide (File Explorer Options/View: hide extensions setting); Travis Everett & Andrew Hutz - CompTIA A+ All-in-One Exam Guide (Folder Options
/View: toggle file extensions); Mark Soper - Mike Meyers' A+ Lab Manual (show/hide extensions and how to change the setting).

質問 # 152
An application's performance is degrading over time. The application is slowing, but it never gives an error and does not crash. Which of the following tools should a technician use to start troubleshooting?

A. Disk
B. Reliability history
C. Computer management
D. Resource monitor

正解：D

解説：
Comprehensive and Detailed Explanation From Exact Extract:
Resource Monitor provides real-time monitoring of system performance and resource usage, including CPU, memory, disk, and network usage. It helps technicians identify performance bottlenecks (e.g., high memory or CPU usage) that can cause slowdowns in applications over time without producing crash errors.
A: Reliability history logs application crashes or errors - not helpful if the app doesn't crash.
B: Computer Management is a broad utility with limited real-time monitoring capability.
D: Disk is too vague - tools like CHKDSK can help with disk errors but not general performance degradation.

質問 # 153
Which of the following types of RAM is typically used in servers?

A. SODIMM
B. DDR3
C. ECC
D. Rambus

正解：C

解説：
Error-correcting code memory is commonly used in servers because it detects and corrects memory errors, improving reliability and stability in critical systems.

質問 # 154
A small office reported a phishing attack that resulted in a malware infection. A technician is investigating the incident and has verified the following:
- All endpoints are updated and have the newest EDR signatures.
- Logs confirm that the malware was quarantined by EDR on one system.
- The potentially infected machine was reimaged.
Which of the following actions should the technician take next?

A. Flash the firmware of the router to ensure the integrity of network traffic.
B. Suggest alternate preventative controls that would include more advanced security software.
C. Install network security tools to prevent downloading infected files from the internet.
D. Discuss the cause of the issue and educate the end user about security hygiene.

正解：D

解説：
With technical controls updated, EDR signatures current, and the infected system reimaged, the next step is to address the human factor. Educating the user on how to recognize phishing attempts and follow safe practices helps prevent recurrence and strengthens the organization's overall security posture.

質問 # 155
An organization is experiencing an increased number of issues. A technician notices applications that are not installed by default. Users are reporting an increased number of system prompts for software licensing. Which of the following would the security team most likely do to remediate the root cause?

A. Enable stricter UAC settings on Windows.
B. Deploy an internal PKI to filter encrypted web traffic.
C. Implement stronger controls to block suspicious websites.
D. Remove users from the local admin group.

正解：D

解説：
If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it's likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.
A). Deploying a PKI helps with secure communications but doesn't address user software installation rights.
C). Blocking suspicious websites is helpful but doesn't prevent local installations.
D). Stricter UAC may add prompts but can still be bypassed by admin users.
