1. You are experimenting with the GCP Translation API. You have created a Jupyter Notebook and plan to use Python 3 to build a proof-of-concept system. What are the first two operations that you would execute in your notebook to start using the Translation API?

2. A developer asks for your help tuning a text-to-speech service that is used with a health and wellness app. The app is designed to run on watches and other personal devices. The sound quality is not as good as the developer would like. What would you suggest trying to improve the quality of sound?

3. You have developed a mobile app that helps travelers quickly find sites of interest. The app uses the GCP Translation service. The initial release of the app used the REST API, but adoption has grown so much that you need higher performance from the API and plan to use gRCP instead. What changes do you need to make to the way that you use the Translation service?

4. Your e-commerce startup has been growing rapidly since its launch six months ago. You are starting to notice that the rate of revenue growth is slowing down. Your board of directors is asking you to develop a strategy to increase revenue. You decide to personalize each customer’s experience. One of the ways in which you plan to implement your strategy is by showing customers products that they are likely to interact with next. What recommendation type would you use?

5. Your team is building a chatbot to support customer support. Domain experts from the customer support team have identified several kinds of questions that the system should support, including questions about returning products, getting technical help, and asking for product recommendations. You will use Dialogflow to implement the chatbot. What component of Dialogflow will you configure to support the three question types?

6. You are using the Cloud Vision API to detect landmarks in images. You are using the batch processing with asynchronous requests. The source images for each batch is in a separate Cloud Storage bucket. There are between 1 and 5,000 images in each bucket. Each batch request processes one bucket. All buckets have the same access controls. Sometimes, the operations succeed and sometimes they fail. What could be the cause of the errors?

7. A developer asks for your help tuning a speech-to-text service that is used to transcribe text recorded on a mobile device. The quality of the transcription is not as good as expected. The app uses LINEAR16 encoding and a sampling rate of 12,000 Hz. What would you suggest to try to improve the quality?

8. You are building a machine learning model to analyze unusual events in traffic through urban areas. Your model needs to distinguish cars, bikes, pedestrians, and buildings. It is especially important that the model be able to identify and track moving vehicles. Video will be streamed to your service from cameras mounted on traffic lights. What GCP service would you use for the object analysis and tracking?

9. As a founder of an e-commerce startup, you are particularly interested in engaging with your customers. You decide to use the GCP Recommendations AI API using the “others you may like recommendation type. You want to maximize the likelihood that users will engage with your recommendations. What optimization objective would you choose?"

10. A startup is building an educational support platform for students from ages 5–18. The platform will allow teachers to post assignments and conduct assessments. Students will be able to upload content, including text and images. The founder of the startup wants to make sure that explicit images are not uploaded. What GCP service would you use?

11. You have been hired by a law firm to help analyze a large volume of documents related to a legal case. There are approximately 10,000 documents ranging from 1 to 15 pages in length. They are all written in English. The lawyers hiring you want to understand who is mentioned in each document so that they can understand how those individuals worked together. What functionality of the Natural Language API would you use?

12. You work for an enterprise with a large fleet of vehicles. The vehicles are equipped with several sensors that transmit data about fuel utilization, speed, and other equipment operating characteristics. The chief of operations has asked you to investigate the feasibility of building a predictive maintenance application that can help identify breakdowns before they occur. You decide to prototype an anomaly detection model as a first step. You want to build this as quickly as possible, so you decide to use a machine learning service. Which GCP service would you use?
