When evaluating the cost associated with a 1 Gbps network link using the standard metrics often applied in networking, the cost is typically represented by the number of hops or the bandwidth of the link divided by the speed. In this context, the option that corresponds with common Cisco practice states that the cost of a link can be defined in a way that considers the physical characteristics and capabilities of the network infrastructure.

In many scenarios following Cisco's guidelines, the cost of a 1 Gbps link is standardized to a value of 4. This metric helps in routing protocols such as OSPF (Open Shortest Path First) and helps determine the optimal path that data should take across the network. Therefore, with the link speed being 1 Gbps, it reflects a moderate cost associated with paths that enable efficient data transfer.

Using a standardized cost allows for predictable outcomes in various networking environments, as network routers will choose paths based on the least cost determined by these metrics. Understanding the basis for the cost assessment is essential in designing and troubleshooting network performance effectively.
