You want to run a single caching HTTP reverse proxy on GCP for a latency-sensitive website.
This specific reverse proxy consumes almost no CPU. You want to have a 30-GB in-memory cache, and need an additional 2 GB of memory for the rest of the processes. You want to minimize cost. How should you run this reverse proxy?

• A. Run it on Compute Engine, and choose a custom instance type with 6 vCPUs and 32 GB of memory.
• B. Run it on Compute Engine, choose the instance type n1-standard-1, and add an SSD persistent disk of 32 GB.
• C. Package it in a container image, and run it on Kubernetes Engine, using n1-standard-32 instances as nodes.
• D. Create a Cloud Memorystore for Redis instance with 32-GB capacity.

You have a batch workload that runs every night and uses a large number of virtual machines (VMs). It is fault-tolerant and can tolerate some of the VMs being terminated. The current cost of VMs is too high.
What should you do?

• A. Run a test using simulated maintenance events.
  If the test is successful, use preemptible N1 Standard VMs when running future jobs.
• B. Run a test using simulated maintenance events.
  If the test is successful, use N1 Standard VMs when running future jobs.
• C. Run a test using a managed instance group.
  If the test is successful, use N1 Standard VMs in the managed instance group when running future jobs.
• D. Run a test using N1 standard VMs instead of N2.
  If the test is successful, use N1 Standard VMs when running future jobs.

Your management has asked an external auditor to review all the resources in a specific project.
The security team has enabled the Organization Policy called Domain Restricted Sharing on the organization node by specifying only your Cloud Identity domain. You want the auditor to only be able to view, but not modify, the resources in that project. What should you do?

• A. Create a temporary account for the auditor in Cloud Identity, and give that account the Security Reviewer role on the project.
• B. Ask the auditor for their Google account, and give them the Viewer role on the project.
• C. Ask the auditor for their Google account, and give them the Security Reviewer role on the project.
• D. Create a temporary account for the auditor in Cloud Identity, and give that account the Viewer role on the project.

You are creating an application that will run on Google Kubernetes Engine. You have identified MongoDB as the most suitable database system for your application and want to deploy a managed MongoDB environment that provides a support SLA. What should you do?

• A. Create a Cloud Bigtable cluster and use the HBase API
• B. Download a MongoDB installation package and run it on Compute Engine instances
• C. Download a MongoDB installation package, and run it on a Managed Instance Group
• D. Deploy MongoDB Alias from the Google Cloud Marketplace

Your organization is a financial company that needs to store audit log files for 3 years. Your organization has hundreds of Google Cloud projects. You need to implement a cost-effective approach for log file retention. What should you do?

• A. Create an export to the sink that saves logs from Cloud Audit to a Coldline Storage bucket.
• B. Write a custom script that uses logging API to copy the logs from Stackdriver logs to BigQuery.
• C. Create an export to the sink that saves logs from Cloud Audit to BigQuery.
• D. Export these logs to Cloud Pub/Sub and write a Cloud Dataflow pipeline to store logs to Cloud SQL.
