Company Overview
HipLocal is a community application designed to facilitate communication between people in close proximity. It is used for event planning and organizing sporting events, and for businesses to connect with their local communities. HipLocal launched recently in a few neighborhoods in Dallas and is rapidly growing into a global phenomenon. Its unique style of hyper-local community communication and business outreach is in demand around the world.
Executive Statement
We are the number one local community app; it's time to take our local community services global. Our venture capital investors want to see rapid growth and the same great experience for new local and virtual communities that come online, whether their members are 10 or 10000 miles away from each other.
Solution Concept
HipLocal wants to expand their existing service, with updated functionality, in new regions to better serve their global customers. They want to hire and train a new team to support these regions in their time zones. They will need to ensure that the application scales smoothly and provides clear uptime data.
Existing Technical Environment
HipLocal's environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform.
The HipLocal team understands their application well, but has limited experience in global scale applications.
Their existing technical environment is as follows:
* Existing APIs run on Compute Engine virtual machine instances hosted in GCP.
* State is stored in a single instance MySQL database in GCP.
* Data is exported to an on-premises Teradata/Vertica data warehouse.
* Data analytics is performed in an on-premises Hadoop environment.
* The application has no logging.
* There are basic indicators of uptime; alerts are frequently fired when the APIs are unresponsive.
Business Requirements
HipLocal's investors want to expand their footprint and support the increase in demand they are seeing. Their requirements are:
* Expand availability of the application to new regions.
* Increase the number of concurrent users that can be supported.
* Ensure a consistent experience for users when they travel to different regions.
* Obtain user activity metrics to better understand how to monetize their product.
* Ensure compliance with regulations in the new regions (for example, GDPR).
* Reduce infrastructure management time and cost.
* Adopt the Google-recommended practices for cloud computing.
Technical Requirements
* The application and backend must provide usage metrics and monitoring.
* APIs require strong authentication and authorization.
* Logging must be increased, and data should be stored in a cloud analytics platform.
* Move to serverless architecture to facilitate elastic scaling.
* Provide authorized access to internal apps in a secure manner.
HipLocal's data science team wants to analyze user reviews.
How should they prepare the data?

A. Use the Cloud Data Loss Prevention API for de-identification of the review dataset.
B. Use the Cloud Data Loss Prevention API for redaction of the review dataset.
C. Use the Cloud Natural Language Processing API for de-identification of the review dataset.
D. Use the Cloud Natural Language Processing API for redaction of the review dataset.

答案：C

問題 #301
For this question, refer to the HipLocal case study.
HipLocal's application uses Cloud Client Libraries to interact with Google Cloud. HipLocal needs to configure authentication and authorization in the Cloud Client Libraries to implement least privileged access for the application. What should they do?

A. Create a service account for the application and for each Google Cloud API used by the application.
Export and deploy the private keys used by the application. Use the service account with one Google Cloud API to interact with Google Cloud.
B. Use the default compute service account to interact with Google Cloud.
C. Create a service account for the application. Export and deploy the private key for the application. Use the service account to interact with Google Cloud.
D. Create an API key. Use the API key to interact with Google Cloud.

答案：D

問題 #302
You are designing an application that shares PDF files containing time-sensitive information with users. The PDF files are saved in Cloud Storage. You need to provide secure access to the files.
You have the following requirements:
- Users should only have access to files that they are allowed to view.
- Users should be able to request to read, write, or delete the PDF
files for 24 hours.
Not all users of the application have a Google account. How should you provide access to data objects?

A. Configure the application to generate signed URLs with an expiration time of 24 hours. Share the signed URLs with users. Attach the signed URL to the PDF files that users require access to.
B. Provide users with the Service Account Token Creator IAM role to impersonate the application's service account. Assign the Cloud Storage User IAM role to the application's service account to access the Cloud Storage bucket. Rotate the application's service account key every 24 hours.
C. Assign the Storage Object User IAM role to users that request access to the PDF files. Set an IAM condition on the role to expire after 24 hours.
D. Generate a service account that grants access to the POF files. Configure the application to provide users with a download link to the service account's key file. Set an expiration time of 24 hours to the service account Keys. Instruct users to authenticate by using the service account key file.

答案：A

解題說明：
Signed URLs are an effective way to provide secure, time-limited access to files stored in Cloud Storage, especially for users without Google accounts. With signed URLs, the application can grant users access to specific files with a specified expiration time (in this case, 24 hours). The signed URL approach meets the requirement for fine-grained, temporary access control without needing users to authenticate via Google accounts or service account keys, which simplifies the process and improves security.

問題 #303
You are planning to add unit tests to your application. You need to be able to assert that published Pub/Sub messages are processed by your subscriber in order. You want the unit tests to be cost-effective and reliable.
What should you do?

A. Use the Pub/Sub emulator.
B. Add a filter by tester to the subscription.
C. Create a topic and subscription for each tester.
D. Implement a mocking framework.

答案：A

問題 #304
Your company's development teams want to use Cloud Build in their projects to build and push Docker images to Container Registry. The operations team requires all Docker images to be published to a centralized, securely managed Docker registry that the operations team manages.
What should you do?

A. Create a separate project for the operations team that has Container Registry configured. Create a Service Account for each development team and assign the appropriate permissions to allow it access to the operations team's registry. Store the service account key file in the source code repository and use it to authenticate against the operations team's registry.
B. Create a separate project for the operations team that has Container Registry configured. Assign appropriate permissions to the Cloud Build service account in each developer team's project to allow access to the operation team's registry.
C. Create a separate project for the operations team that has the open source Docker Registry deployed on a Compute Engine virtual machine instance. Create a username and password for each development team.
Store the username and password in the source code repository and use it to authenticate against the operations team's Docker registry.
D. Use Container Registry to create a registry in each development team's project. Configure the Cloud Build build to push the Docker image to the project's registry. Grant the operations team access to each development team's registry.

答案：D
