A company runs an Azure Event Hubs namespace with a Standard tier namespace. They observe that the ingress is throttled during peak hours. They need to increase throughput without changing the number of partitions. What should they do?

Use a larger message batch size.

Switch to a Basic tier namespace.

Increase the throughput units (TUs) on the namespace.

Add more partitions to the existing event hub.

A company wants to publish events from multiple internal applications to a single Event Grid domain. Each application should only be able to publish to its own topic within the domain. What should you use to control access?

Use a single domain-level access key for all applications.

Use Azure AD roles to grant access to the entire domain.

Create a shared access policy per topic and assign each application its own key.

Create a separate Event Grid domain for each application.

An organization uses Event Grid to deliver events to an on-premises webhook. The webhook is not publicly accessible. They want to use Azure AD authentication for the webhook endpoint. What should they do?

Create a private endpoint for the webhook.

Use a shared access signature (SAS) in the webhook URL.

Use an Azure Function with a VNet integration to call the on-premises webhook.

Expose the webhook through Azure Application Gateway and configure Azure AD authentication on the gateway.

What is the primary purpose of Azure Event Hubs?

To provide a message queue for decoupling applications

To ingest and process large volumes of telemetry data

To route events from sources to subscribers

To store events for long-term archival

An Event Grid subscription delivers events to an Azure Function. The function processes events and writes to a database. Occasionally, the function fails and the event is retried, causing duplicate database writes. The team wants to ensure idempotent processing. What should they implement?

Disable retries on the Event Grid subscription.

Use a queue trigger instead of an Event Grid trigger.

Increase the function's retry count.

Use the event ID as a unique key in the database to detect duplicates.
