Your organization wants to make its internal shuttle service route more efficient. The shuttles currently stop at all pick-up points across the city every 30 minutes between 7 am and 10 am. The development team has already built an application on Google Kubernetes Engine that requires users to confirm their presence and shuttle station one day in advance. What approach should you take?

C- C. 1. Define the optimal route as the shortest route that passes by all shuttle stations with confirmed attendance at the given time under capacity constraints. 2. Dispatch an appropriately sized shuttle and indicate the required stops on the map.

You were asked to investigate failures of a production line component based on sensor readings. After receiving the dataset, you discover that less than 1% of the readings are positive examples representing failure incidents. You have tried to train several classification models, but none of them converge. How should you resolve the class imbalance problem?

C- C. Downsample the data with upweighting to create a sample with 10% positive examples.

You want to rebuild your ML pipeline for structured data on Google Cloud. You are using PySpark to conduct data transformations at scale, but your pipelines are taking over 12 hours to run. To speed up development and pipeline run time, you want to use a serverless tool and SQL syntax. You have already moved your raw data into Cloud Storage. How should you build the pipeline on Google Cloud while meeting the speed and processing requirements?

D- D. Ingest your data into BigQuery using BigQuery Load, convert your PySpark commands into BigQuery SQL queries to transform the data, and then write the transformations to a new table.

What would be the appropriate configuration to build an ML model for detecting real-time anomalies in sensor data using Pub/Sub to handle incoming requests and storing the results for further analytics and visualization?

A- 1 = Dataflow, 2 = Vertex AI, 3 = BigQuery

You are training a deep learning model for semantic image segmentation with reduced training time. While using a Deep Learning VM Image, you receive the following error: The resource 'projects/deeplearning-platforn/zones/europe-west4-c/acceleratorTypes/nvidia-tesla-k80' was not found. What should you do?

B- Ensure that the required GPU is available in the selected region.

You trained a model in a Vertex AI Workbench notebook that has good validation RMSE. You defined 20 parameters with the associated search spaces that you plan to use for model tuning. You want to use a tuning approach that maximizes tuning job speed. You also want to optimize cost, reproducibility, model performance, and scalability where possible if they do not affect speed. What should you do?

D- D. Refactor the notebook into a parametrized and dockerized Python script, and push it to Container Registry. Use the command line to set up a hyperparameter tuning job in Vertex AI. Use the created image and include Random Search as an algorithm where maximum trial count is equal to parallel trial count.

You work on a growing team of more than 50 data scientists who all use Vertex AI. You are designing a strategy to organize your jobs, models, and versions in a clean and scalable way. Which strategy should you choose?

C- Use labels to organize resources into descriptive categories. Apply a label to each created resource so that users can filter the results by label when viewing or monitoring the resources.

Your team is building a convolutional neural network (CNN)-based architecture from scratch. The preliminary experiments running on your on-premises CPU-only infrastructure were encouraging, but have slow convergence. You have been asked to speed up model training to reduce time-to-market. You want to experiment with virtual machines (VMs) on Google Cloud to leverage more powerful hardware. Your code does not include any manual device placement and has not been wrapped in Estimator model-level abstraction. Which environment should you train your model on?

A- C. A Deep Learning VM with an n1-standard-2 machine and 1 GPU with all libraries pre-installed.

You used Vertex AI Workbench user-managed notebooks to develop a TensorFlow model. The model pipeline accesses data from Cloud Storage, performs feature engineering and training locally, and outputs the trained model in Vertex AI Model Registry. The end-to-end pipeline takes 10 hours on the attached optimized instance type. You want to introduce model and data lineage for automated re-training runs for this pipeline only while minimizing the cost to run the pipeline. What should you do?

C- C. 1. Create a Cloud Storage bucket to store metadata. 2. Write a function that saves data and model metadata by using TensorFlow ML Metadata in one time-stamped subfolder per pipeline run. 3. Configure a scheduled recurring execution for the notebook. 4. Access data and model metadata in Cloud Storage.

You started working on a classification problem with time series data and achieved an area under the receiver operating characteristic curve (AUC ROC) value of 99% for training data after just a few experiments. You haven't explored using any sophisticated algorithms or spent any time on hyperparameter tuning. What should your next step be to identify and fix the problem?

B- B. Address data leakage by applying nested cross-validation during model training.
