Dynatrace Pro Certification Practice Exam

Where is RUM (Real User Monitoring) data stored?

1. Elasticsearch

2. Cassandra

3. Transactions Store

4. Data Lake

The correct answer is: Elasticsearch

Real User Monitoring (RUM) data is primarily stored in the Data Lake. The Data Lake is designed to handle large volumes of diverse data types collected from various sources, and it provides a scalable and efficient storage solution for monitoring data. By utilizing a Data Lake architecture, Dynatrace can ensure that RUM data is kept in a centralized repository, allowing for extensive data analysis and advanced querying capabilities. Elasticsearch, while often associated with indexing and searching capabilities in observability solutions, is not where RUM data is stored. It is more commonly used for transaction data or logs that require quick retrieval and searching capabilities. In contrast, RUM data captures end-user interactions and environment performance metrics, making it more suited for storage in the Data Lake. Cassandra, known for its distributed database capabilities, is utilized within some monitoring solutions but does not specifically serve as the storage mechanism for RUM data in Dynatrace. The Transactions Store is used for storing transaction-specific information, but it does not encompass the full range of user interaction data that RUM captures. In summary, recognizing that RUM data is housed in the Data Lake aligns with the understanding of how Dynatrace aggregates and processes diverse data types for effective user experience monitoring and performance analysis.
