  1. See Explanation section for answer.

Answer(s): A

Explanation:




A key mechanism that allows Azure Data Lake Storage Gen2 to provide file system performance at object storage scale and prices is the addition of a hierarchical namespace. This allows the collection of objects/files within an account to be organized into a hierarchy of directories and nested subdirectories in the same way that the file system on your computer is organized. With a hierarchical namespace enabled, a storage account becomes capable of providing the scalability and cost-effectiveness of object storage, with file system semantics that are familiar to analytics engines and frameworks.
One advantage of hierarchical namespace is atomic directory manipulation: Object stores approximate a directory hierarchy by adopting a convention of embedding slashes (/) in the object name to denote path segments.

When provisioning an Azure Cosmos DB account, which feature provides redundancy within an Azure region?

  1. multi-master replication
  2. Availability Zones
  3. the strong consistency level
  4. automatic failover

Answer(s): B

Explanation:

With Availability Zone (AZ) support, Azure Cosmos DB will ensure replicas are placed across multiple zones within a given region to provide high availability and resiliency to zonal failures.
Note: Azure Cosmos DB provides high availability in two primary ways. First, Azure Cosmos DB replicates data across regions configured within a Cosmos account. Second, Azure Cosmos DB maintains 4 replicas of data within a region.

What is a benefit of the Azure Cosmos DB Table API as compared to Azure Table storage?

  1. provides resiliency if an Azure region fails
  2. supports partitioning
  3. provides a higher storage capacity
  4. supports a multi-master model

Answer(s): D

Explanation:

Multi-master support for Azure Cosmos DB is now available in all public regions.
Azure CosmosDB table API is a key-value storage hosted in the cloud. It's a part of Azure Cosmos DB, that is Microsoft's multi-model database.
