What is Orion High Availability (HA), and what benefits does it provide for NPM?

• A. HA duplicates data on a single server
• B. HA provides no failover capabilities
• C. HA requires dedicated storage hardware
• D. Orion HA uses a secondary server to mirror the primary, providing failover protection for the Orion Platform services and preserving monitoring with minimal downtime

Answer: (D)

Orion High Availability is about keeping the Orion Platform running by using a second server that mirrors the primary. This setup lets the backup take over the Orion Platform services if the primary encounters a failure, ensuring monitoring continues with minimal downtime. Because the secondary is prepared to assume control, the transition preserves the current monitoring state—polling, alerts, dashboards, and configurations—so there’s little disruption to NPM operations. The idea that data would be duplicated on a single server isn’t how HA works; redundancy comes from having a separate, standby machine ready to take over. Requiring dedicated storage hardware isn’t a defining trait of Orion HA, and the absence of failover would defeat the purpose of high availability.
