Which role assignment for Operator2 satisfies the technical requirements?

The Desktop Virtualization Host Pool Contributor role allows Operator2 to manage host pools, including adding and removing session hosts, which directly addresses the technical requirement of managing session hosts. The Desktop Virtualization Session Host Operator role primarily allows viewing and performing basic operations on session hosts, but not adding or removing them from a host pool. The Desktop Virtualization User Session Operator role focuses on managing user sessions, not the host pool or session hosts themselves. The Desktop Virtualization Contributor role is a broader role that grants full control over all Azure Virtual Desktop resources, which is more permissive than necessary for simply managing session hosts within a host pool.
