Explanation

In Cisco ISE, a 'split' or distributed deployment is used to scale performance by distributing workloads across multiple nodes. The AAA (Authentication, Authorization, and Accounting) load is the primary load that is split between Policy Service Nodes (PSNs). Multiple PSNs can be deployed so that RADIUS/TACACS+ authentication and authorization requests are distributed (load-balanced) across them. This improves scalability and provides redundancy. Network admission control and device admission are functions performed as part of AAA, not separate load categories. Log collection is handled by the Monitoring and Troubleshooting (MnT) node, which is a separate persona and is not what is 'split' in this context.
