In this lesson
Prepare for the AZ-305 exam (Microsoft Azure Solutions Architect Expert). In this lesson: designing semi-structured and unstructured data: Azure Cosmos DB and its APIs (NoSQL, MongoDB, Apache Cassandra, Gremlin, Table, PostgreSQL), the five consistency levels and partition keys, Blob Storage access tiers and Data Lake Storage, Azure Files and Azure NetApp Files, and durability with redundancy options, immutable storage, soft delete, versioning and customer-managed keys. Includes three original practice questions.
Preview the topics

- A broker must keep trade records for seven years, and regulators require that nobody can modify or delete them during that time. What should the architect recommend?
