Summary: In-memory caching layer (via dedicated gateway) reducing RU cost/latency for repeated reads.
Overview
The Azure Cosmos DB integrated cache is an in-memory caching layer, provisioned via a dedicated gateway, that automatically caches the results of point reads and queries to reduce RU consumption and latency for repeated read operations, without requiring changes to application query logic.

Answer Key
Answers are listed at the very end so you can attempt the questions first.
- Q1 (Integrated Cache): A. Reduced RU consumption and latency for repeated point reads and queries — The integrated cache reduces RU cost and latency by serving repeated reads/queries from an in-memory cache.
- Q2 (Integrated Cache): A. A dedicated gateway — The integrated cache is provisioned through a dedicated gateway deployment.
