1. A director at Mountkirk Games has asked for your recommendation on how to measure the success of the migration to GCP. The director is particularly interested in customer satisfaction. What KPIs would you recommend?

2. Mountkirk Games will analyze game players

3. In the Dress4Win case study, the volume of data and compute load will grow with respect to what factor?

4. You manage a service with several databases. The queries to the relational database are increasing in latency. Reducing the amount of data in tables will improve performance and reduce latency. The application administrator has determined that approximately 60 percent of the data in the database is more than 90 days old and has never been queried and does not need to be in the database. You are required to keep the data for five years in case it is requested by auditors. What would you propose to decrease query latency without increasing costs

5. What security control can be used to help detect changes to data?

6. TerramEarth has interviewed dealers to better understand their needs regarding data. Dealers would like to have access to the latest data available, and they would like to minimize the amount of data they have to store in their databases and object storage systems. How would you recommend that TerramEarth provide data to their dealers?

7. You are consulting for a multinational company that is moving its inventory system to GCP. The company wants to use a managed database service, and it requires SQL and strong consistency. The database should be able to scale to global levels. What service would you recommend?

8. Your company has a data classification scheme for categorizing data as secret, sensitive, private, and public. There are no confidentiality requirements for public data. All other data must be encrypted at rest. Secret data must be encrypted with keys that the company controls. Sensitive and private data can be encrypted with keys managed by a third party. Data will be stored in GCP. What would you recommend in order to meet these requirements while minimizing cost and administrative overhead?

9. A new data warehouse project is about to start. The data warehouse will collect data from 14 different sources initially, but this will likely grow over the next 6 to 12 months. What managed GCP service would you recommend for managing metadata about the data warehouse sources?

10. Your company is running several custom applications that were written by developers who are no longer with the company. The applications frequently fail. The DevOps team is paged more for these applications than any others. You propose replacing those applications with several managed services in GCP. A manager who is reviewing your cost estimates for using managed services in GCP notes that the cost of the managed services will be more than what they pay for internal servers. What would you recommend as the next step for the manager?

11. A customer-facing application is built using a microservices architecture. One of the services does not scale as fast as the service that sends it data. This causes the sending service to wait while the other service processes the data. You would like to change the integration to use asynchronous instead of synchronous calls. What is one way to do this?

12. You have received complaints from customers about long wait times while loading application pages in their browsers, especially pages with several images. Your director has tasked you with reducing latency when accessing and transmitting data to a client device outside the cloud. Which of the following would you use?

13. You have been hired to consult with a new data warehouse team. They are struggling to meet schedules because they repeatedly find problems with data quality and have to write preprocessing scripts to clean the data. What managed service would you recommend for addressing these problems?

14. You are working with a U.S. hospital to extract data from an electronic health record (EHR) system. The hospital has offered to provide business requirements, but there is little information about regulations in the documented business requirements. What regulations would you look to for more guidance on complying with relevant regulations?

15. Your company uses Apache Spark for data science applications. Your manager has asked you to investigate running Spark in the cloud. Your manager

16. A product manager at TerramEarth would like to use the data that TerramEarth collects to predict when equipment will break down. What managed services would you recommend TerramEarth to consider?

17. Mountkirk Games is implementing a player analytics system. You have been asked to document requirements for a stream processing system that will ingest and preprocess data before writing it to the database. The preprocessing system will collect data about each player for one minute and then write a summary of statistics about that database. The project manager has provided the list of statistics to calculate and a rule for calculating values for missing data. What other business requirements would you ask of the project manager?

18. Your company has large volumes of unstructured data stored on several network-attached storage systems. The maintenance costs are increasing, and management would like to consider alternatives. What GCP storage system would you recommend?

19. You have deployed an application that receives data from sensors on TerramEarth equipment. Sometimes more data arrives than can be processed by the current set of Compute Engine instances. Business managers do not want to run additional VMs. What changes could you make to ensure that data is not lost because it cannot be processed as it is sent from the equipment? Assume that business managers want the lowest-cost solution.
