Which parameter is NOT considered in selecting the best path by routing protocols?

Routing protocols use various parameters to determine the best path for data packets across a network. Among these parameters, cost, latency, and administrator preference all play significant roles in the decision-making process.

Cost refers to the metric assigned to a route, which can be based on factors such as bandwidth, hop count, or other considerations. Lower cost routes are generally preferred, allowing for efficient data transmission.

Latency measures the time it takes for a packet to traverse the network. Routing protocols often select paths that minimize latency to ensure faster delivery of data.

Administrator preference allows network administrators to influence routing decisions. This can be achieved through configuration adjustments such as setting route preferences or adjusting metrics, enabling more control over routing behavior according to specific network design goals.

In contrast, randomized selection does not align with the principles of effective routing. Routing protocols aim to make informed decisions based on measurable and logical parameters rather than relying on chance. Hence, it is not considered when selecting the best path, as it would lead to unpredictable and potentially inefficient routing outcomes.
