Enable Authentication to Google Cloud Platform APIs
Question
You are building an application that will run in your data center.
The application will use Google Cloud Platform (GCP) services like AutoML.
You created a service account that has appropriate access to AutoML.
You need to enable authentication to the APIs from your on-premises environment.
What should you do?

Explanation:
To enable authentication to Google Cloud Platform (GCP) APIs from an on-premises environment, you can use a service account. A service account is a special type of Google account that belongs to your application or a virtual machine (VM), instead of to an individual end user. Service accounts can be used to authenticate and authorize API calls to GCP services, and can be configured with granular permissions to access specific GCP resources.
To use a service account for authentication from your on-premises environment, you need to follow these steps:
Create a service account: You can create a service account in the GCP Console, Cloud SDK, or using the REST API. When creating the service account, you need to specify the roles or permissions that the service account should have. In this case, you need to grant the service account appropriate permissions to use AutoML.
Generate a private key for the service account: Once you have created the service account, you need to generate a private key file that will be used to authenticate API calls from your on-premises environment. You can generate the private key using the Cloud Console or the gcloud command-line tool. The private key will be a JSON file that contains the service account email address and a private key that can be used to sign API requests.
Use the private key in your on-premises application: Finally, you need to use the private key in your on-premises application to authenticate API calls to GCP services. Depending on the programming language and API client you are using, you may need to configure the API client to use the private key as a credential when making API calls.
Option B, using gcloud to create a key file for the service account, is partially correct, but it does not provide enough information about how to use the key file in your on-premises application. Option C, setting up direct interconnect between your data center and GCP, is not necessary for authentication purposes and is also more complicated and expensive than using a service account. Option D, granting a user account permissions similar to the service account permissions, is not recommended as it is less secure than using a service account, since user accounts are tied to individual people rather than to applications or VMs.
