DP-420 Question #67: Real Exam Question with Answer & Explanation

Question

The server-side latency direct and server-side latency gateway are two metrics that can be used to view the server-side latency of any operation in two different connection modes. Which of the following API(s) in Azure Cosmos DB supports both of these metrics?

Options

• ASQL
• BMongoDB
• CCassandra
• DGremlin
• ETable

Explanation

{"question_number": 6, "question_summary": "Which Azure Cosmos DB APIs support both server-side latency direct and server-side latency gateway metrics", "correct_answer": "A and E", "explanation": "The correct answers are A (SQL) and E (Table). Azure Monitor exposes two server-side latency metrics for Azure Cosmos DB: 'Server Side Latency' for direct mode connections and 'Server Side Latency Gateway' for gateway mode connections. These metrics are only available for the Core (SQL) API and the Table API. The MongoDB, Cassandra, and Gremlin APIs have their own wire-protocol-specific monitoring paths and do not expose both of these specific latency metrics in Azure Monitor. When designing monitoring solutions for Cosmos DB accounts using these two APIs, engineers can leverage both metrics to distinguish latency introduced by the gateway layer versus the backend.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
