DP-420 Exam Dumps : Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB

Batch size: An integer that represents how many objects are being written to Cosmos DB collection in each batch. Usually, starting with the default batch size is sufficient. To further tune this value, note:

Cosmos DB limits single request ' s size to 2MB. The formula is " Request Size = Single Document Size * Batch Size " . If you hit error saying " Request size is too large " , reduce the batch size value.

The larger the batch size, the better throughput the service can achieve, while make sure you allocate enough RUs to empower your workload.

Box 1 = Randomized

Box 2 = Deterministic

Always Encrypted for Az ure Cosmos DB supports two types of encryption: deterministic and randomized 1 . Deterministic encryption always produces the same encrypted value for any given plain text value. Randomized encryption produces a different encrypted value for the same plain text value.

For dateOfBirth, randomized encryption is the strongest type of encryption because it provides better protection against statistical analysis and brute-force attacks.  Deterministic encryption would not be suitable for dateOfBirth because it could r eveal patterns or allow equality comparisons 1 .

For healthStatus, deterministic encryption is the strongest type of encryption because it allows queries to perform equality comparisons and filters on the encrypted prop erty.  Randomized encryption would not be suitable for healthStatus because it would prevent any queries on the encrypted property 1 .
