20+ practice questions focused on Architecting Low-Code ML Solutions — one of the most tested topics on the Google Professional Machine Learning Engineer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Architecting Low-Code ML Solutions PracticeA company wants to use BigQuery ML to train a DNN_CLASSIFIER model on a dataset with 100 million rows. They are concerned about training time and cost. Which approach can help optimize training performance while staying within BigQuery ML?
Explanation: BigQuery ML automatically handles many training optimizations internally, including distributed training across slots and query optimization, so no additional configuration is strictly required to train a DNN_CLASSIFIER on 100 million rows. While options like sampling or limiting iterations can reduce cost, they change model quality and are not the 'optimize while staying within BigQuery ML' answer the exam expects. The correct answer reflects that BigQuery ML manages training performance natively.
A company needs to analyze customer feedback from app reviews to identify common themes and sentiment. They have millions of reviews in multiple languages. Which combination of pre-built APIs should they use?
Explanation: The reviews are text in multiple languages, so the Translation API is needed to convert them into a single language (e.g., English) that the Natural Language API can analyze for sentiment and entity/theme extraction. The Natural Language API supports multiple languages for sentiment, but its entity and syntax analysis is optimized for English, and translation ensures consistent theme detection across all reviews. Combining Translation API then Natural Language API directly addresses the multilingual text requirement.
A retail company uses Recommendations AI to power personalized product recommendations on their website. They notice that the 'frequently-bought-together' model is not capturing complementary items that are often purchased in the same session but not necessarily in the same transaction. Which TWO actions should they take to improve the model?
Explanation: Option B is correct because enabling the 'others-you-may-like' recommendation type complements 'frequently-bought-together' by surfacing related items based on broader user behavior and co-view/co-purchase signals, which helps capture complementary products that appear in the same session but not the same transaction. Option E is correct because Recommendations AI learns from user event data, and ingesting session-level events such as product detail views, add-to-cart actions, and page views within the same session gives the model the behavioral context needed to identify items frequently browsed together even when they are not bought in one transaction. The unmarked options do not belong: A would reduce historical signal and hurt learning, C introduces a separate custom modeling path rather than improving the existing Recommendations AI model, and D would restrict the model to only 'frequently-bought-together', which is exactly the limitation being addressed.
A retail company wants to build a recommendation system for their e-commerce website. They have user purchase history and product metadata. Which Google Cloud service is most suitable for building a 'frequently bought together' recommendation model with minimal custom ML development?
Explanation: Recommendations AI is a Google Cloud service specifically designed for building recommendation systems with minimal ML expertise. It offers pre-built model types, including 'frequently bought together', which directly addresses the requirement. This allows the retail company to deploy a recommendation model quickly without custom development.
A retailer wants to implement a recommendation engine that suggests products based on a user's current cart. They have limited ML expertise and want a quick deployment. Which Recommendations AI model type should they use?
Explanation: The 'Frequently bought together' model type is the correct choice because it directly leverages collaborative filtering based on co-purchase patterns in historical transaction data, enabling the retailer to recommend items commonly purchased alongside the current cart contents. This model requires minimal ML expertise and can be quickly deployed using pre-built Recommendations AI templates, as it does not require user-level personalization or real-time session data.
