By adjusting the VLAN settings on the switch, the technician can ensure that the sales department has access to the marketing department's network resources.

C. Switch: VLANs are configured on switches to logically separate or combine network segments.

Why the other options are incorrect:

A. Network card: A network card is a hardware component that connects a device to a network, but it does not configure VLANs.

B. Patch panel: A patch panel is used to organize and manage network cables but does not play a role in VLAN configuration.

D. Server: A server may host resources, but VLANs are managed at the switch level.

E. Hub: A hub is a basic networking device that simply forwards traffic; it cannot be used to configure VLANs.

Comprehensive and Detailed In-Depth Explanation:

If two devices have the same static IP address, an IP conflict occurs. This results in both devices being intermittently disconnected or unable to communicate on the network. It’s a common mistake when copying configurations manually.

Option B: DNS conflicts wouldn’t cause total disconnection — and wouldn't occur just from copying IP settings.

Option C: A cable issue would only affect one workstation.

Option D: Switchport security issues wouldn't affect both machines simultaneously unless port security was configured very specifically.

CompTIA A+ Core 1 Exam Objective Reference:

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

If a desktop PC shuts down suddenly and there is a burning smell coming from the area where it is connected to the wall socket, the first step should be to check that the power cable is not damaged. A damaged power cable can cause electrical shorts or overheating, leading to sudden shutdowns and a burning smell. Inspecting the power cable for fraying, cuts, or other damage can help identify if it is the source of the problem.

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, including virtualized hardware, storage, and networking components. It offers the infrastructure on which clients can install their operating systems and applications, providing an equivalent to physical hardware environments. This allows developers and businesses to develop and run their solutions without managing physical servers. SaaS delivers software applications over the internet, PaaS provides a platform allowing customers to develop, run, and manage applications, and DBaaS offers database services in the cloud.
