Question 76

You are training an object detection model using a Cloud TPU v2. Training time is taking longer than expected. Based on this simplified trace obtained with a Cloud TPU profile, what action should you take to decrease training time in a cost-efficient way?

Options:

A.

Move from Cloud TPU v2 to Cloud TPU v3 and increase batch size.

B.

Move from Cloud TPU v2 to 8 NVIDIA V100 GPUs and increase batch size.

C.

Rewrite your input function to resize and reshape the input images.

D.

Rewrite your input function using parallel reads, parallel processing, and prefetch.

Question 77

You are an ML engineer on an agricultural research team working on a crop disease detection tool to detect leaf rust spots in images of crops to determine the presence of a disease. These spots, which can vary in shape and size, are correlated to the severity of the disease. You want to develop a solution that predicts the presence and severity of the disease with high accuracy. What should you do?

Options:

A.

Create an object detection model that can localize the rust spots.

B.

Develop an image segmentation ML model to locate the boundaries of the rust spots.

C.

Develop a template matching algorithm using traditional computer vision libraries.

D.

Develop an image classification ML model to predict the presence of the disease.

Question 78

You are an ML engineer at a global shoe store. You manage the ML models for the company's website. You are asked to build a model that will recommend new products to the user based on their purchase behavior and similarity with other users. What should you do?

Options:

A.

Build a classification model

B.

Build a knowledge-based filtering model

C.

Build a collaborative-based filtering model

D.

Build a regression model using the features as predictors

Question 79

You are training an object detection machine learning model on a dataset that consists of three million X-ray images, each roughly 2 GB in size. You are using Vertex AI Training to run a custom training application on a Compute Engine instance with 32-cores, 128 GB of RAM, and 1 NVIDIA P100 GPU. You notice that model training is taking a very long time. You want to decrease training time without sacrificing model performance. What should you do?

Options:

A.

Increase the instance memory to 512 GB and increase the batch size.

B.

Replace the NVIDIA P100 GPU with a v3-32 TPU in the training job.

C.

Enable early stopping in your Vertex AI Training job.

D.

Use the tf.distribute.Strategy API and run a distributed training job.
