What should you configure when you create the function app?

1 / 1점

The Windows operating system and the App Service plan hosting plan

The Windows operating system and the Consumption plan hosting plan

The Docker container and an App Service plan that uses the S1 pricing tier

The Docker container and an App Service plan that uses the B1 pricing tier

When you're using the Consumption plan, instances of the Azure Functions host are dynamically added and removed based on the number of incoming events.

3.

질문 3

You have an Azure App Service API that enables users to upload documents to the cloud with a mobile device. A mobile app connects to the service by using REST API calls. When a new document is uploaded to the service, the service extracts the document metadata. Usage statistics for the app show significant increases in app usage.

The extraction process is CPU-intensive. You have to modify the API to use a queue. You need to ensure that the solution scales, handles request spikes, and reduces costs between request spikes.

What should you do?

1 / 1점

Configure a series of CPU-optimized virtual machine instances and install extraction logic to process a queue.

Move the extraction logic into an Azure Function. Create a queue-triggered function to process the queue.

Configure an Azure Container Service to retrieve items from a queue and run across a pool of virtual machine nodes using the extraction logic.

Configure a CPU-optimized virtual machine and install the web app service on the new instance.

맞습니다

The serverless and on-demand automatic scalability features of Azure Functions will be best for this solution.

1 / 1점

Reads from the output, writes to the input

Reads from input, writes to output

Reads from input, writes to output and input

맞습니다

질문 1

You’re developing an HTTP-triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob. The app continues to time out after four minutes. The app must process the blob data. You need to ensure the app does not time out and processes the blob data.

Solution: Pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a queue trigger function and return an immediate HTTP success response.

Does the solution meet the goal?

1 / 1점

Yes

No

맞습니다

Large, long-running functions can cause unexpected timeout issues. Whenever possible, refactor large functions into smaller function sets that work together and return responses fast. For example, a webhook or HTTP trigger function might require an acknowledgment response within a certain time limit; it's common for webhooks to require an immediate response. You can pass the HTTP trigger payload into a queue to be processed by a queue trigger function. This approach lets you defer the actual work and return an immediate response.

질문 2

You are developing an Azure Function App that processes images that are uploaded to an Azure Blob container. Images must be processed as quickly as possible after they are uploaded, and the solution must minimize latency. You create code to process images when the Function App is triggered.

You need to configure the Function App.

What should you do?

1 / 1점

Use an App Service plan. Configure the Function App to use an Azure Blob Storage trigger.

Use a Consumption plan. Configure the Function App to use an Azure Blob Storage trigger.

Use a Consumption plan. Configure the Function App to use a Timer trigger.

Use an App Service plan. Configure the Function App to use an Azure Blob Storage input trigger.

맞습니다

The requirement is to minimize the latency. If your function app is on the Consumption plan, there can be up to a 10-minute delay in processing new blobs if a function app has gone idle. To avoid this latency, you should use an App Service plan with Always On enabled.

3.

질문 3

You are developing a software as a service (SaaS) offering to manage photos. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2. When photos are uploaded, they must be processed to produce a thumbnail version of the image. The process to produce a mobile-friendly version of the image should start in less than one minute.

You need to design the process that starts the photo processing.

Solution: Move photo processing to an Azure Function triggered from the blob upload.

Does the solution meet the goal?

1 / 1점

Yes

No

맞습니다

The Blob storage trigger starts a function when a new or updated blob is detected. The blob contents are provided as input to the function. The Azure Blob storage trigger requires a general-purpose storage account. Storage V2 accounts with hierarchal namespaces are also supported.
