All 220-1101 Test Inside CompTIA Questions

Comprehensive and Detailed In-Depth Explanation:

An IP address starting with 169.254.x.x is a self-assigned address (also called APIPA – Automatic Private IP Addressing). It’s used when a client device cannot contact a DHCP server. This address allows limited communication on the local network segment but no internet access.

Option A: DHCP reservations assign specific IPs from the DHCP server — they don’t result in APIPA.

Option B: Dynamic assignment from DHCP assigns valid IPs in the proper subnet, not 169.254.x.x.

Option D: Static IPs are manually set and would not fall in the 169.254.x.x range unless set incorrectly.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.6: Given a scenario, configure and troubleshoot network connectivity.

An IP address beginning with 169.254 indicates that the device has not received a valid IP from the DHCP server. Rebooting the router can resolve minor configuration or network glitches, allowing DHCP to function correctly. The other options, such as adjusting lease time or static IP addresses, do not address the core problem. CompTIA A+ Core 1 objectives emphasize DHCP troubleshooting in SOHO networks.

Vertical lines on a laser printer printout are most commonly associated with issues in the drum unit. The drum is a crucial component in the laser printing process, where it receives an electrostatic image of the document to be printed and transfers toner to the paper. If there are defects or damage to the drum's surface, it can result in vertical lines appearing on the printed output as the drum fails to evenly distribute toner across the page.
