A company has an Azure Function that processes incoming messages from an Azure Storage queue. For each message, the function must write a new file to Azure Blob Storage. The function should use an output binding to write the blob. What should the developer use as the output binding?

Blob output binding with a path that includes the message ID

Cosmos DB output binding that writes a document

Queue output binding that writes a message to another queue

HTTP output binding that returns a response

An e-commerce platform uses Azure Functions to react to new customer orders. Each order is stored as a JSON document in Azure Cosmos DB. When a new order is inserted, the function must send a confirmation message to an Azure Service Bus queue. Which trigger and binding should the function use?

Timer trigger with a Cosmos DB input binding

Cosmos DB trigger with a Service Bus output binding

Service Bus trigger with a Cosmos DB output binding

HTTP trigger with a Cosmos DB input binding

A company exposes an Azure Function as a webhook for a third-party service. The service sends a secret in the 'X-Webhook-Secret' header. The function must validate the secret and return 401 if it is invalid. The function is currently set to authorization level 'Anonymous'. What should the developer do?

Keep the authorization level as 'Anonymous' and validate the header in the function code.

Change the authorization level to 'Function' and require the third-party service to use the function key.

Use Azure AD authentication and require the third-party service to obtain a token.

Set the authorization level to 'Admin' and rely on the platform to validate the secret.
