D306 Azure Developer Associate - Set 3 - Part 1

Correct Answer: Automatic scaling and pay-per-execution billing

The Consumption Plan for Azure Functions automatically scales and charges only for the resources consumed during function execution.

Correct Answer: Archive

The Archive tier is designed for long-term storage of data that is rarely accessed and can tolerate slower retrieval times.

Correct Answer: Strong

Strong consistency ensures that all reads return the most recent committed version of data, providing the highest level of consistency.

Correct Answer: Timer trigger

The Timer trigger allows Azure Functions to execute at specified intervals based on a schedule.

Correct Answer: Long-running, stateful workflows

Azure Durable Functions enable the orchestration of long-running, stateful workflows, such as chaining multiple functions together or running functions in parallel.

Correct Answer: Contributor

The Contributor role grants full access to manage resources but does not allow for managing user access or permissions.

Correct Answer: Session

The Session consistency level is the default for most Cosmos DB applications because it provides a good balance between consistency and performance.

Correct Answer: Variables

Variables in an ARM template allow you to define reusable values that can be referenced throughout the template.

Correct Answer: Azure Event Hubs

Azure Event Hubs is optimized for ingesting large streams of real-time data from sources such as IoT devices and processing them in real time.

Correct Answer: To manage state across multiple consumers

The lease container is used by the change feed processor to manage state across multiple consumers, ensuring that data is processed only once.

Correct Answer: To define granular permissions for SAS tokens

Stored access policies allow you to define permissions for shared access signatures (SAS tokens) to control access to Azure Storage resources.

Correct Answer: Read-Access Geo-Redundant Storage (RA-GRS)

RA-GRS allows for the automatic replication of data to another Azure region, ensuring high availability and disaster recovery capabilities.

Correct Answer: Message Sessions

Message Sessions in Azure Service Bus guarantee that messages are processed in the same order they are received, maintaining FIFO (First-In-First-Out) semantics.

Correct Answer: To authenticate the function call

The "x-functions-key" header is used to pass the function-specific API key, which is required for authenticating HTTP requests to Azure Functions.

Correct Answer: How long data will be retained before deletion

TTL in Cosmos DB defines the period after which data will be automatically deleted, useful for scenarios like expiring temporary data.

Correct Answer: Azure Logic Apps

Azure Logic Apps enable the automation of workflows that connect APIs, databases, and other services.

Correct Answer: Gremlin API

The Gremlin API in Cosmos DB allows you to perform advanced queries on graph-based data using the TinkerPop framework.

Correct Answer: Ensures that soft-deleted items cannot be permanently deleted until the retention period expires

Purge Protection prevents the permanent deletion of items in Azure Key Vault until the retention period has passed.

Correct Answer: To manage long-running, stateful workflows

Azure Durable Functions allow developers to manage long-running workflows by providing stateful orchestration of function executions.

Correct Answer: Logical partition

A logical partition in Cosmos DB ensures that all items within it share the same partition key, facilitating efficient data organization.
