Your team detected a spike of errors in an application running on Cloud Run in your production project. The application is configured to read messages from Pub/Sub topic A, process the messages, and write the messages to topic B. You want to conduct tests to identify the cause of the errors. You can use a set of mock messages for testing. What should you do?
You need to load-test a set of REST API endpoints that are deployed to Cloud Run. The API responds to HTTP POST requests Your load tests must meet the following requirements:
• Load is initiated from multiple parallel threads
• User traffic to the API originates from multiple source IP addresses.
• Load can be scaled up using additional test instances
You want to follow Google-recommended best practices How should you configure the load testing'?
Your team is creating a serverless web application on Cloud Run. The application needs to access images stored in a private Cloud Storage bucket. You want to give the application Identity and Access Management (IAM) permission to access the images in the bucket, while also securing the services using Google-recommended best practices What should you do?
You want to view the memory usage of your application deployed on Compute Engine. What should you do?
Before promoting your new application code to production, you want to conduct testing across a variety of different users. Although this plan is risky, you want to test the new version of the application with production users and you want to control which users are forwarded to the new version of the application based on their operating system. If bugs are discovered in the new version, you want to roll back the newly deployed version of the application as quickly as possible.
What should you do?
You are building a new API. You want to minimize the cost of storing and reduce the latency of serving
images.
Which architecture should you use?
You have an on-premises application that authenticates to the Cloud Storage API using a user-managed service account with a user-managed key. The application connects to Cloud Storage using Private Google Access over a Dedicated Interconnect link. You discover that requests from the application to access objects in the Cloud Storage bucket are failing with a 403 Permission Denied error code. What is the likely cause of this issue?
You are designing a chat room application that will host multiple rooms and retain the message history for each room. You have selected Firestore as your database. How should you represent the data in Firestore?
Create a collection for the rooms. For each room, create a document that lists the contents of the messages
Create a collection for the rooms. For each room, create a collection that contains a document for each message
Create a collection for the rooms. For each room, create a document that contains a collection for documents, each of which contains a message.
Create a collection for the rooms, and create a document for each room. Create a separate collection for messages, with one document per message. Each room’s document contains a list of references to the messages.
You are responsible for deploying a new API. That API will have three different URL paths:
• https://yourcompany.com/students
• https://yourcompany.com/teachers
• https://yourcompany.com/classes
You need to configure each API URL path to invoke a different function in your code. What should you do?
You are building an API that will be used by Android and iOS apps The API must:
• Support HTTPs
• Minimize bandwidth cost
• Integrate easily with mobile apps
Which API architecture should you use?
