AZ-204 Developing for Microsoft Azure Exam Prep - Data Encryption and Structured Query Language (SQL) Databases

The video tutorial covers the use of Azure databases, focusing on Transparent Data Encryption (TDE). It explains how Azure automatically manages encryption keys and offers options for using service-managed or customer-managed keys. The tutorial also discusses configuring encryption at both the server and database levels, including scenarios where encryption might be turned off. Additionally, it highlights the limitations of encrypting the master database in SQL Server due to key storage requirements.

What is the primary function of Transparent Data Encryption (TDE) in Azure databases?

• To compress data for storage efficiency

• To manage user access permissions

• To encrypt data at rest and decrypt it transparently

• To provide backup solutions for databases

How can you manage your own encryption keys in Azure?

• By disabling TDE and using manual encryption

• By entering a key identifier or selecting from a key vault

• By storing keys in a local database

• By using a third-party encryption service

At which level can you turn off encryption for a specific database in Azure?

• Database level

• Server level

• Application level

• Network level

Why might you choose to disable encryption at the database level?

• To improve data retrieval speed

• If the database is frequently accessed

• If encryption is already handled at the client level

• To reduce storage costs

Why is the master database in Azure not encrypted by default?

• It is only used for temporary data

• It is always stored in a secure location

• It is not important for security

• It contains the keys used for encrypting other data
