Passcert verified Google Professional Machine Learning Engineer Exam Dumps help you in preparation for the exam in a short period of time. If you completely focus on our valid Google Professional Machine Learning Engineer Exam Dumps, then you will be able to pass the Google Professional Machine Learning Engineer exam in the first attempt.

A Professional Machine Learning Engineer designs, builds, and productionizes ML models to solve business challenges using Google Cloud technologies and knowledge of proven ML models and techniques. The ML Engineer is proficient in all aspects of model architecture, data pipeline interaction, and metrics interpretation and needs familiarity with application development, infrastructure management, data engineering, and security.

The Machine Learning Engineer certification exam is a two-hour exam which assesses individuals’ ability to frame ML problems, develop ML models, and architect ML solutions. It also evaluates abilities to automate ML pipelines, orchestrate ML pipelines, prepare data, process data, as well as monitor, optimize, and maintain ML solutions. We recommend you have at least three years of industry experience, including one year of experience designing and managing solutions using Google Cloud before taking the exam.

Frame ML problems

Architect ML solutions

Prepare and process data

Develop ML models

Monitor, optimize, and maintain ML solutions

NO.1 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?

A. Build a collaborative-based filtering model

B. Build a classification model

C. Build a regression model using the features as predictors

D. Build a knowledge-based filtering model

Answer: A

NO.2 You have been asked to develop an input pipeline for an ML training model that processes images from disparate sources at a low latency. You discover that your input data does not fit in memory. How should you create a dataset following Google-recommended best practices?

A. Convert the images to tf .Tensor Objects, and then run tf. data. Dataset. from_tensors ().

B. Convert the images to tf .Tensor Objects, and then run Dataset. from_tensor_slices{).

C. Convert the images Into TFRecords, store the images in Cloud Storage, and then use the tf. data API to read the images for training

D. Create a tf.data.Dataset.prefetch transformation

Answer: C

NO.3 You work for an online retail company that is creating a visual search engine. You have set up an end-to-end ML pipeline on Google Cloud to classify whether an image contains your company's product. Expecting the release of new products in the near future, you configured a retraining functionality in the pipeline so that new data can be fed into your ML models. You also want to use Al Platform's continuous evaluation service to ensure that the models have high accuracy on your test data set. What should you do?

A. Keep the original test dataset unchanged even if newer products are incorporated into retraining

B. Extend your test dataset with images of the newer products when they are introduced to retraining

C. Replace your test dataset with images of the newer products when they are introduced to retraining.

D. Update your test dataset with images of the newer products when your evaluation metrics drop below a pre-decided threshold.

Answer: C

NO.4 You are developing a Kubeflow pipeline on Google Kubernetes Engine. The first step in the pipeline is to issue a query against BigQuery. You plan to use the results of that query as the input to the next step in your pipeline. You want to achieve this in the easiest way possible. What should you do?

A. Use the BigQuery console to execute your query and then save the query results Into a new BigQuery table.

B. Write a Python script that uses the BigQuery API to execute queries against BigQuery Execute this script as the first step in your Kubeflow pipeline

C. Locate the Kubeflow Pipelines repository on GitHub Find the BigQuery Query Component, copy that component's URL, and use it to load the component into your pipeline. Use the component to execute queries against BigQuery

D. Use the Kubeflow Pipelines domain-specific language to create a custom component that uses the Python BigQuery client library to execute queries

Answer: A

NO.5 You manage a team of data scientists who use a cloud-based backend system to submit training jobs. This system has become very difficult to administer, and you want to use a managed service instead. The data scientists you work with use many different frameworks, including Keras, PyTorch, theano. Scikit-team, and custom libraries. What should you do?

A. Set up Slurm workload manager to receive jobs that can be scheduled to run on your cloud infrastructure.

B. Create a library of VM images on Compute Engine; and publish these images on a centralized repository

C. Configure Kubeflow to run on Google Kubernetes Engine and receive training jobs through TFJob

D. Use the Al Platform custom containers feature to receive training jobs using any framework

Answer: A
