1. You are a developer at a startup company that has just released a new service. During development, you made suboptimal coding choices to keep the project on schedule. You are now planning your next two weeks of work, which you decide will include implementing a feature the product manager wanted in the initial release but was postponed to a release occurring soon after the initial release. You also include time to refactor code that was introduced to correct a bug found immediately before the planned release date. That code blocks the worst impact of the bug, but it does not correct the flaw. Revising that suboptimal code is an example of what?

2. Your startup has released a new online game that includes features that allow users to accumulate points by playing the game. Points can be used to make in-game purchases. You have discovered that some users are using bots to play the game programmatically much faster than humans can play the game. The use of bots is unauthorized in the game. You modify the game API to prevent more than 10 function calls per user, per minute. This is an example of what practice?

3. A team of developers is creating a set of tests for a new service. The tests are defined using a set of conditions or input values and expected output values. The tests are then executed by reading the test data source, and for each test the software being tested is executed and the output is compared to the expected value. What kind of testing framework is this?

4. A junior developer asks your advice about performing authentication in API functions. The developer wants to know how they can allow users of the API to make assertions about what they are authorized to do. What would you recommend?

5. You are a developer at a startup company that is planning to release its first version of a new mobile service. You have discovered a design flaw that generates and sends more data to mobile devices than is needed. This is increasing the latency of messages between mobile devices and backend services running in the cloud. Correcting the design flaw will delay the release of the service by at least two weeks. You decide to address the long latency problem by coding a workaround that does not send the unnecessary data. The design flaw is still there and is generating unnecessary data, but the service can ship under these conditions. This is an example of what?

6. You are setting up a new laptop that is configured with a standard set of tools for developers and architects, including some GCP SDK components. You will be working extensively with the GCP SDK and want to know specifically which components are installed and up to date. What command would you run on the laptop?

7. A team of developers is tasked with developing an enterprise application. They have interviewed stakeholders and collected requirements. They are now designing the system and plan to begin implementation next. After implementation, they will verify that the application meets specifications. They will not revise the design once coding starts. What application development methodology is this team using?

8. You are a consultant to an insurance company migrating to GCP. Five petabytes of business-sensitive data need to be transferred from the on-premises data center to Cloud Storage. You have a 10 GB network between the on-premises data center and Google Cloud. What transfer option would you recommend?

9. A junior developer asks your advice about handling errors in API functions. The developer wants to know what kind of data and information should be in an API error message. What would you recommend?

10. You are migrating a data warehouse from an on-premises database to BigQuery. You would like to write a script to perform some of the migration steps. What component of the GCP SDK will you likely need to use to create the new data warehouse in BigQuery?

11. A team of developers is tasked with developing an enterprise application. They meet daily with stakeholders to discuss the state of the project. The developers and stakeholders have identified a set of functionalities to be implemented over the next two weeks. After some design work, coding begins. A new requirement is discovered, and developers and stakeholders agree to prioritize implementing a feature to address this newly discovered requirement. As developers complete small functional units of code, they test it. If the code passes the tests, the code unit is integrated with the version-controlled codebase. What application development methodology is this team using?

12. As a developer of a backend service for managing inventory, your manager has asked you to include a basic API for the inventory service. You plan to follow best practice recommendations. What is the minimal set of API functions that you would include?

13. A team of developers is tasked with developing an enterprise application. They have interviewed stakeholders and set a scope of work that will deliver a subset of the functionality needed. Developers and stakeholders have identified risks and ways of mitigating them. They then proceed to gather requirements for the subset of functionalities to be implemented. That is followed by design, implementation, and testing. There is no collaboration between developers and stakeholders until after testing, when developers review results with stakeholders and plan the next iteration of development. What application development methodology is this team using?

14. As a consultant to an insurance company migrating to the Google Cloud, you have been asked to lead the effort to migrate data from AWS S3 to Cloud Storage. Which transfer method would you consider first?

15. Your company is moving an enterprise application to Google Cloud. The application runs on a cluster of virtual machines, and workloads are distributed by a load balancer. Your team considered revising the application to use containers and the Kubernetes Engine, but they decide not to make any unnecessary changes before moving the application to the cloud. This is an example of what migration strategy?
