1. Your organization plans to migrate its financial transaction data to Google Cloud. Auditors need to view the data and run reports in BigQuery, but they are not allowed to modify the data. You want to apply the principle of least privilege and follow Google-recommended practices. What should you do?

2. You are managing your company's first Google Cloud project. Project leads, developers, and internal testers will participate in the project, which includes sensitive information. You need to ensure that only specific members of the development team have access to sensitive information. You want to assign the appropriate Identity and Access Management (IAM) roles that also require the least amount of maintenance. What should you do?

3. You are responsible for monitoring all configuration changes to your Cloud Storage and Firestore resources in real-time. For each change, you need to invoke a security script that will verify the compliance of the change in near real-time. You want to accomplish this with minimal setup. What should you do?

4. Your application needs to process a significant rate of transactions. The rate of transactions exceeds the processing capabilities of a single virtual machine (VM). You want to spread transactions across multiple servers in a managed instance group in real time and in the most cost-effective manner. Which Google Cloud product should the transactions be sent to?

5. Your team needs to directly connect your on-premises servers to several VMs inside of a Virtual Private Cloud (VPC). You want to set up a fast and secure network connection with minimal maintenance and cost. What should you do?
