What type of map can help in tracking the progress of a network upgrade or network outages?

The correct response is a network key map, as it specifically details aspects of the network's infrastructure, components, and connections. This type of mapping provides a visual representation of the network's layout, including critical points of interest, connections, and configurations. When tracking the progress of network upgrades or identifying areas affected by outages, a network key map is essential because it allows coordinators and technicians to pinpoint specific locations and resources involved in the network.

Through this mapping, teams can efficiently communicate and coordinate their activities, thereby facilitating a quicker response to issues that may arise during upgrades or outages. Additionally, having access to an updated network key map ensures all relevant personnel are aware of the current configurations and the status of various components, making it easier to assess the impact of any changes or problems.

In contrast, other options such as street maps and geographical maps do not provide the necessary detail about the network's infrastructure, while a design layout map may not include the real-time data required for tracking actual progress.
