Associate Atlas Administrator

As a MongoDB Associate Atlas Administrator, I possess a strong understanding of MongoDB Atlas fundamentals, including cloud architecture best practices and the effective management of organizations, projects, and clusters. My capabilities extend to deploying various cluster types such as dedicated, shared, and serverless, and managing documents within collections using tools like the Data Explorer. I am proficient in general Atlas administration, which includes differentiating between Atlas and database users, determining optimal cluster architecture including tier types and hardware configurations, and configuring settings like autoscaling and termination protection based on cluster tiers.

A significant aspect of my expertise lies in ensuring security within Atlas. I can implement robust user management features for both database and Atlas users by applying roles, permissions, access levels, and adhering to the Principle of Least Privilege. Furthermore, I am skilled in configuring networking access through methods like peering and private endpoints, utilizing audit logs and activity feeds for oversight, and understanding Atlas's default encryption mechanisms for data at rest and in transit. My knowledge also covers comprehensive database backup and recovery procedures, allowing me to define appropriate backup policies based on RPO/RTO and business requirements for different cluster types, and execute restore operations to maintain data integrity and availability.

My certification also signifies my ability to effectively monitor MongoDB performance by identifying and analyzing core metrics for both the database (like query targeting and replication lag) and the underlying system (such as CPU, memory, and network traffic), understanding metric availability across different cluster types. I can configure and respond to alerts for critical events, analyze query performance using tools like the profiler and Performance Advisor, and retrieve and manage log data. Additionally, I am equipped to plan for database upgrades and maintenance, including designing zero-downtime strategies, understanding MongoDB's rolling maintenance, and preparing rollback plans to ensure smooth operations and feature compatibility.
