Answer:
D. A network administrator.
Step-by-step explanation:
- A network administrator is responsible for the day-to-day operations of a computer network, including installing, configuring, and maintaining network devices, such as servers, routers, switches, and firewalls. They are knowledgeable about the technical aspects of a network and can troubleshoot and resolve issues as they arise. They are also responsible for ensuring that the network is secure, and that data is backed up and protected. Therefore, a network administrator would be the best fit for Eva's needs, as they have in-depth knowledge of network devices and can keep her network running efficiently.
While network architects design and plan computer networks, network security analysts focus on protecting networks from cyber threats, and network analysts analyze and optimize network performance, they may not have the same level of day-to-day operational knowledge as a network administrator.
