What aspect of systems is a network engineer NOT typically associated with?

A network engineer is primarily focused on the design, implementation, maintenance, and management of communication networks, which includes activities such as setting up network infrastructure and monitoring for security breaches. Their role typically involves ensuring that the network operates efficiently and securely, protecting against unauthorized access and vulnerabilities.

While upgrading hardware systems can sometimes fall within their purview—especially when it pertains to network devices like routers and switches—designing web pages is not part of a network engineer's responsibilities. Web page design is usually the domain of web developers or web designers who specialize in creating the look and functionality of websites, often using languages and tools such as HTML, CSS, JavaScript, and various content management systems. Therefore, a network engineer would not typically be involved in the aesthetics or user interface concerns associated with web development, making that option clearly distinct from their usual functions.
