What load balancing rules should an admin create to address slowness caused by simultaneous self-service developers in a multi-node environment?

In a multi-node environment, managing resources effectively is crucial, especially when multiple self-service developers are accessing the server simultaneously, which can lead to performance issues. The correct choice, which refers to the conditions involving the "Central" node and a non-empty resource stream, is significant because it helps direct traffic appropriately during peak usage times.

In this context, the "Central" node typically acts as the main hub for Qlik Sense, handling most of the requests and tasks. By creating load balancing rules targeted at the Central node when resources are not empty, you ensure that the node responsible for key operations is effectively utilized, thereby alleviating potential bottlenecks. This means that simultaneous developers can be efficiently managed without overwhelming the Central node.

The choice indicates that when there is a demand for resources (non-empty resources), the system can distribute these demands intelligently, ensuring that no single node remains overloaded. This leads to improved performance and a better user experience for developers.

The conditions in the other options do not target traffic as effectively or are focused on development nodes rather than the Central node, which is less optimal in addressing slowness in a production environment where developers are actively working.
