Question 4

You are writing a single-page web application with a user-interface that communicates with a third-party API for content using XMLHttpRequest. The data displayed on the UI by the API results is less critical than other data displayed on the same web page, so it is acceptable for some requests to not have the API data displayed in the UI. However, calls made to the API should not delay rendering of other parts of the user interface. You want your application to perform well when the API response is an error or a timeout.

What should you do?

Set the asynchronous option for your requests to the API to false and omit the widget displaying the API results when a timeout or error is encountered.

Set the asynchronous option for your request to the API to true and omit the widget displaying the API results when a timeout or error is encountered.

Catch timeout or error exceptions from the API call and keep trying with exponential backoff until the API response is successful.

Catch timeout or error exceptions from the API call and display the error response in the UI widget.

Question 5

Your team develops services that run on Google Cloud. You need to build a data processing service and will use Cloud Functions. The data to be processed by the function is sensitive. You need to ensure that invocations can only happen from authorized services and follow Google-recommended best practices for securing functions. What should you do?

Enable Identity-Aware Proxy in your project. Secure function access using its permissions.

Create a service account with the Cloud Functions Viewer role. Use that service account to invoke the function.

Create a service account with the Cloud Functions Invoker role. Use that service account to invoke the function.

Create an OAuth 2.0 client ID for your calling service in the same project as the function you want to secure. Use those credentials to invoke the function.

Question 8

You have an application that uses an HTTP Cloud Function to process user activity from both desktop browser and mobile application clients. This function will serve as the endpoint for all metric submissions using HTTP POST.

Due to legacy restrictions, the function must be mapped to a domain that is separate from the domain requested by users on web or mobile sessions. The domain for the Cloud Function is https://fn.example.com. Desktop and mobile clients use the domain https://www.example.com. You need to add a header to the function's HTTP response so that only those browser and mobile sessions can submit metrics to the Cloud Function. Which response header should you add?

Access-Control-Allow-Origin: *

Access-Control-Allow-Origin: https://*.example.com

Access-Control-Allow-Origin: https://fn.example.com

Access-Control-Allow-origin: https://www.example.com

Question 9

You have an HTTP Cloud Function that is called via POST. Each submission's request body has a flat, unnested JSON structure containing numeric and text data. After the Cloud Function completes, the collected data should be immediately available for ongoing and complex analytics by many users in parallel. How should you persist the submissions?

Directly persist each POST request's JSON data into Datastore.

Transform the POST request's JSON data, and stream it into BigQuery.

Transform the POST request's JSON data, and store it in a regional Cloud SQL cluster.

Persist each POST request's JSON data as an individual file within Cloud Storage, with the file name containing the request identifier.

Question 10

Your security team is auditing all deployed applications running in Google Kubernetes Engine. After completing the audit, your team discovers that some of the applications send traffic within the cluster in clear text. You need to ensure that all application traffic is encrypted as quickly as possible while minimizing changes to your applications and maintaining support from Google. What should you do?

Use Network Policies to block traffic between applications.

Install Istio, enable proxy injection on your application namespace, and then enable mTLS.

Define Trusted Network ranges within the application, and configure the applications to allow traffic only from those networks.

Use an automated process to request SSL Certificates for your applications from Let's Encrypt and add them to your applications.
