Technology Questions
Upgrades, cloning, patches, testing, instance management, Instance Data Replication, Hermes messaging, and platform core services.
About Technology
Technology domain covers the technical aspects of platform management including Instance Data Replication (IDR), Hermes messaging for high availability, upgrade best practices, and cloning with data preservers. Understanding these technical foundations is crucial for platform stability.
Why This Matters for Your Exam
Technology accounts for approximately 22.9% of the CPOA exam - the largest domain. Questions focus on IDR adapters and monitoring, Hermes near/far cluster architecture, AHA transfer processes, and upgrade best practices.
Key Concepts to Master
Understand how IDR replicates data between instances and its various adapters (Calculation, Map, Time Zone Conversion). Know the difference between near and far clusters in Hermes and how AHA transfer switches to the newly-active data center cluster.
Exam Tips
Never apply upgrades directly to production without testing in sub-production first. The IDR Monitoring Dashboard tracks producer/consumer replication sets, scheduled jobs, and seeding requests. Messages go to the near cluster under normal operation.
