Newly Released CompTIA 220-1201 Exam PDF

A valid public IP address must fall outside the private IP address ranges:

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

66.157.195.20 is outside these ranges, making it a public IP address.

Why Not A, C, D: These IPs fall within private IP address ranges.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, IP addressing​.

A. Run the maintenance application:

Most modern printers include a built-in maintenance application that can calibrate the print heads and correct alignment issues. Running this tool is the first step to address misalignment.

Incorrect Options:

B. Clean the rollers: Cleaning rollers is typically done to resolve paper feed or jamming issues, not alignment problems.

C. Upgrade the firmware: While updating firmware is beneficial for performance improvements, it is not the first step for fixing alignment.

D. Reinstall the drivers: Misaligned printing is usually hardware-related, not a driver issue.

Key Takeaway: The maintenance application should be run first to resolve alignment issues in a newly installed printer.

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.
