If operators need to identify networked devices by name, which should be confirmed with the network manager?

Use of a static IP system
Presence of a firewall
Use of DNS or WINS
Network protocol type

The correct answer is: Use of DNS or WINS

The use of DNS (Domain Name System) or WINS (Windows Internet Name Service) is crucial when operators need to identify networked devices by name, as these services are specifically designed to translate device names into IP addresses. DNS is the more commonly used protocol in modern networking, allowing users to connect to devices using human-readable names instead of tedious numerical IP addresses. WINS, while less common now, serves a similar purpose for Windows networks. Confirming the use of these services with the network manager ensures that networked devices can be correctly resolved by name, facilitating easier management and troubleshooting. Operators can quickly reference devices by their assigned names, improving the efficiency of network operations and reducing errors associated with IP address management. The other options, while related to network management, do not directly address the need for identifying devices by name. Static IP systems relate to how devices are assigned IPs rather than their naming resolution. The presence of a firewall is significant for security but does not affect name resolution. The type of network protocol used can influence communication but also does not pertain directly to device identification by name.
