Okta Administrator Certification Practice Exam

To achieve high availability for the Okta Access Gateway (OAG) or Okta’s on-premises agents (OPP), installing agents on at least two separate servers is essential. This ensures that if one server goes down or experiences issues, the other can continue to function and provide uninterrupted service.

By having two agents, you can achieve load balancing and redundancy. This means both agents can handle requests simultaneously, improving overall system performance and reliability. In case one agent fails or requires maintenance, the other agent can take over, allowing for continuous service availability, which is a critical aspect of high availability design.

Installing only one server does not provide the necessary redundancy, as it creates a single point of failure. A configuration with three or four servers offers even more redundancy and resilience, but the minimum requirement for establishing high availability is two separate servers. Thus, having two agents installed strikes a balance between sufficient redundancy and optimal resource usage for maintaining high service availability.
