Which of these capabilities is essential for MID Servers in a cluster?

For MID Servers in a cluster, it is essential that they have the same defined capabilities. This uniformity is crucial because it ensures that all servers in the cluster can effectively share the load and manage tasks consistently. When MID Servers possess the same capabilities, they can efficiently handle failover situations, where if one server goes down, another can seamlessly take over without any disruption in performance. This consistency also simplifies management and configuration, as all servers can be administered as a single entity, ensuring that they are aligned in terms of functionality and performance.

Having diverse capabilities or supporting different applications can lead to potential inconsistencies and issues, especially when attempting to distribute workloads or during failover events. Consequently, maintaining the same capabilities across all MID Servers in a cluster is vital for reliability, performance, and ease of administration in the ServiceNow Discovery process.
