質問 # 117
A technician is troubleshooting internet connectivity issues after a firewall update. Users report that they can access local network resources, such as printers and shares, but cannot access the internet. Which of the following settings is most likely causing the issue?
- A. Default gateway
- B. Subnet mask
- C. Static IP assignments
- D. VLANs
正解：A
解説：
Comprehensive and Detailed In-Depth Explanation:
If users canaccess local network resourcesbut not theinternet, the most likely culprit is amisconfigured or missing default gateway. The default gateway routes traffic from the local network to external networks (i.e., the internet). If it's not properly set or was altered during a firewall update, internet traffic won't be forwarded correctly.
* Option A:Static IPs could cause conflict, but wouldn't affect only external access if configured correctly.
* Option C:An incorrect subnet mask could isolate devices, but local communication would likely be impacted too.
* Option D:VLANs segment networks; while misconfigured VLANs could cause access issues, they'd more likely isolate local traffic as well.
CompTIA A+ Core 1 Exam Objective Reference:
* Objective 2.6: Given a scenario, configure and troubleshoot network connectivity.

質問 # 119
A technician needs to figure out why a laser printer is intermittently not feeding paper to print. The technician verifies the issue by running several copy-and-print tests. Which of the following should the technician do next?
- A. Clean the pickup rollers.
- B. Select the correct paper size.
- C. Replace the toner cartridge.
- D. Update the printer drivers.
正解：A
解説：
When a laser printer intermittently fails to feed paper, the most common hardware cause is worn or dirty pickup rollers. These rollers grab the paper from the tray and move it into the printer. Over time, dust, paper debris, or worn rubber reduces their effectiveness, causing feeding issues.
From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.3 - Troubleshoot printing problems:
"If the printer is not picking up paper correctly or is experiencing paper jams, check and clean or replace the pickup rollers and separation pads as these are responsible for feeding paper into the print path." Other options like updating drivers, selecting paper size, or replacing toner will not resolve a mechanical paper feed problem.
