Exam Content Breakdown

It is important to note that the C100DBA test is broken into various sections, each focused on a specific aspect of MongoDB administration. This is a quick overview of the areas that are covered:

1. MongoDB Architecture (20%)

• A brief overview of MongoDB: Understanding the fundamental principles of MongoDB, as well as its document-based database model, and how it is compared with traditional databases.
• Replication: Implementing replica sets in order to ensure high availability and redundancy of data. This includes setting up replica sets, recognizing the primary and secondary nodes, and failover procedures.
• Sharding: Understanding the way MongoDB shares data across multiple servers through the sharding technique. This article focuses on the shard keys, distribution of chunks,s and balancing data across clusters.

2. Deployment and Operations (25 %)

• Installation and Configuration: Installing MongoDB on different platforms and setting it up for production use.
• Configuration: Setting up MongoDB to optimize performance, which includes tuning the database to optimize storage capacity, I/O on disks and the performance of networks.
• Recover and Backup: MongoDB allows regular backups to be made through tools like the mongodump tool and also mongorestore. Point-in-time recovery is achieved using replica sets and the Oplog that records every write operation, allowing data to be restored at the time.
•  Security: Setting up authentication, authorization, along encryption for secure MongoDB databases.

3. MongoDB Data Management (20 %)

• Operation CRUD: Understanding the basics of Create, Read, Update, deletion (CRUD) actions and the method by which they are executed in MongoDB.
• Indexes: How to build, manage, and optimize indexes for better performance of queries.
• Aggregation Framework: using the aggregation pipeline for complicated queries and transforms on data.

4. Monitoring and Performance Tuning (15 %)

• Monitoring tools: Monitoring MongoDB’s tools to monitor performance, pinpoint bottlenecks and optimize the execution of queries.
• Performance tuning: Analyzing and tuning the performance of databases through indexing optimization of queries and adjustments to hardware.
• Logs and metrics: Understanding the logs and metrics of MongoDB to find and fix problems with database operations.

5. Data Consistency and Durability (20 %)

• Writing Concern Understanding the various levels of Concern for writing in MongoDB and their effect on data durability and consistency.
• Read Problem: Controlling data consistency in reads, especially in distributed environments using replica sets.
• Transactions: How to make use of MongoDB’s multi-document transactions to ensure consistency and integrity of data across all operations.
