A technician is troubleshooting a connectivity issue on a network computer. The technician runs ipconfig in a command prompt and receives the following IP address:169.254.0.6. Which of the following is most likely the type of IP address being assigned?
Correct Answer:
C
Comprehensive and Detailed In-Depth Explanation:
An IP address starting with169.254.x.xis aself-assigned address(also calledAPIPA– 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 butno 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.

A small company wants the ability to print in full color but needs to pay a minimal initial purchase price for the printer Which of the following is the best option?
Correct Answer:
B
Inkjet printers are the best choice for a small company seeking full-color printing with a minimal initial cost. While they have higher operating costs (due to ink), they are affordable and capable of high-quality color output.
Why Not A (Thermal printer): Thermal printers are not designed for color printing and are typically used for labels or receipts.
Why Not C (Dot matrix printer): Dot matrix printers are outdated, noisy, and do not support full-color printing.
Why Not D (Laser printer): Laser printers have lower running costs but a higher initial purchase price, especially for color models.

Which of the following networking devices will most likely need to be installed in between the ISP running DOCSIS and the LAN in a SOHO environment?
Correct Answer:
C
Comprehensive and Detailed Step-by-Step Explanation:
To determine the correct device, we need to understand how a DOCSIS (Data Over Cable Service Interface Specification) network functions in a Small Office/Home Office (SOHO) environment:
* C. Cable Modem:
A cable modem is required to convert the signal provided by the ISP (Internet Service Provider) over a DOCSIS network into a format that is usable by the local area network (LAN).
DOCSIS is a standard for high-speed internet over cable television infrastructure, and the cable modem acts as the gateway between the ISP's coaxial network and the LAN. Without the cable modem, devices in the LAN would not be able to access the internet. Reference: CompTIA A+ Core 1 Exam Objectives (220-1201), Domain 2.2 – Compare and contrast Internet connection types, network types, and their features.
Incorrect Options:
* A. Switch:
A switch is used to connect multiple devices within the LAN. It does not connect the LAN to the ISP's DOCSIS network.
* B. Firewall:
While firewalls provide security by managing inbound and outbound traffic, they do not serve as the interface between the ISP and LAN.
* D. Router:
A router directs traffic between different networks (e.g., between a LAN and the internet). However, in a DOCSIS network, the cable modem is the device that first connects to the ISP. Many modern cable modems also include built-in routers, but the modem is the primary device needed.
* E. Access Point:
An access point provides wireless connectivity within the LAN. It does not connect directly to the ISP or handle DOCSIS signals.
Key Takeaway:The correct device required to interface between the ISP's DOCSIS network and the SOHO LAN is the cable modem.

After a technician installs a new motherboard, the computer will not start and fails POST. The technician verifies the power supply is functioning as expected, and the CPU is installed correctly. Which of the following steps should the technician complete next?
Correct Answer:
C
Comprehensive and Detailed In-Depth Explanation:
A common reason for aPOST failureafter a motherboard installation isimproperly seated RAM. The system requires working memory to successfully complete POST. Reseating (removing and reinserting) the RAM ensures it's making proper contact with the motherboard.
✑ Option A:Flashing the BIOS is not possible if the system won??t POST.
✑ Option B:A dead CMOS battery can cause BIOS settings to reset, but it usually won??t prevent POST entirely.
✑ Option D:Reinstalling the old motherboard is premature — basic troubleshooting steps should be completed first.
