MongoDB Atlas Admin Associate study guide
MongoDB Atlas Admin Associate · Work through your exam, one topic at a time.
The MongoDB Atlas Admin Associate credential is aimed at administrators who run day-to-day operations on MongoDB Atlas rather than developers writing application queries. It validates that you can stand up a cluster with the right tier, region, and topology, then keep it secure, reachable, observable, recoverable, and reproducible. The MongoDB Atlas Admin Associate study guide has 8 sections and about 2,486 words.
01Atlas Deployment and Cluster Configuration
This domain tests how you choose and configure Atlas cluster topology: dedicated versus shared tiers, replica set and sharded layouts, region placement, scaling, and maintenance behavior. Dedicated clusters (M10 and above) provide isolated resources, Atlas-managed backups, private connectivity, and configurable IOPS; M0/Flex are for development and have feature limits.
325 words, about 2 min02Security, Authentication, and Authorization
This domain tests identity and access separation in Atlas: who can manage the platform, who can read or write data, how each is authenticated, and how data is protected. Atlas users are control-plane identities for the UI, CLI, and API.
318 words, about 2 min03Networking and Connectivity
This domain tests how clients reach Atlas privately and securely: access lists, VPC peering, private endpoints, DNS, and TLS. Atlas clusters have public endpoints by default.
315 words, about 2 min04Monitoring, Alerting, and Performance Tuning
This domain tests how you observe Atlas health, configure alerts, and use Atlas tooling to find and fix slow queries. Atlas metrics cover CPU, memory, disk utilization and IOPS, connections, opcounters, replication lag, cache, and query targeting.
311 words, about 2 min05Backup, Restore, and Data Recovery
This domain tests backup design and restore execution: what Atlas protects, how far back you can recover, and how to prove recovery works. Atlas-managed cloud backups and point-in-time restore require dedicated M10+ clusters.
320 words, about 2 min06Automation and Tooling
This domain tests repeatable operations: using the Atlas Administration API, CLI, Terraform, Kubernetes Operator, and database tools safely. The Atlas Administration API is the foundation for automation.
311 words, about 2 min07Data Migration and Data Movement
This domain tests choosing a migration method, preserving data fidelity, and cutting over with minimal downtime. mongodump and mongorestore move BSON and indexes and suit offline or smaller migrations.
300 words, about 2 min08Troubleshooting and Operational Readiness
This domain tests systematic diagnosis and operational readiness: isolating connectivity, authentication, performance, and failover issues before they become outages. Troubleshoot in layers: DNS, network path, TLS, authentication, authorization, then cluster and query performance.
