A company needs to run batch processing jobs regularly on large datasets. Which GCP solution should they choose?
ACloud Run
BCloud Dataflow
CCompute Engine
DApp Engine
Explanation
Cloud Dataflow is optimized for batch processing, unlike the others.
Q72
You are configuring a machine learning model with high variance. What is a recommended approach to improve the model?
AIncrease training data size
BDecrease training data size
CUse linear regression
DReduce feature set complexity
Explanation
Increasing training data can help reduce overfitting due to high variance.
Q73
You are configuring a TensorFlow model in Vertex AI. What is the purpose of using a custom training pipeline?
AHandle data preprocessing automatically.
BOptimize hyperparameters effectively.
CDefine and automate training workflows.
DProvide pre-trained models only.
Explanation
Custom training pipelines automate the training workflow in Vertex AI, while other options do not represent the pipeline's primary purpose.
Q74
A company needs to classify images using a machine learning model. Which Google Cloud service can offer this functionality without managing infrastructure?
ACloud Functions
BAI Platform Prediction
CCloud Run
DBigQuery ML
Explanation
AI Platform Prediction allows image classification without managing infrastructure, while other options do not specifically focus on machine learning classification.
Q75
What happens when you enable AutoML in Vertex AI for a dataset?
ATraining begins immediately.
BIt requires manual feature selection.
CModels will be trained automatically.
DNo data exploration occurs.
Explanation
Enabling AutoML allows for automatic training and model recommendation, while the other options imply incorrect manual requirements or lack of exploration.
Q76
Which Google Cloud service is best for managing APIs?
ACloud Endpoints
BCloud Functions
CCloud Pub/Sub
DCloud Storage
Explanation
Cloud Endpoints is specifically designed to create, secure, and monitor APIs, while the others serve different purposes.
Q77
A company needs real-time processing of streaming data. Which Google Cloud solution should they use?
ACloud Dataflow
BBigQuery
CDataproc
DCloud Storage
Explanation
Cloud Dataflow is designed for real-time data processing, while the others focus on batch processing or storage.
Q78
You are configuring a machine learning model to predict customer churn. What happens when you set the threshold too low?
AHigh precision, low recall
BHigh recall, low precision
CBalanced accuracy
DHigh false negative rate
Explanation
Setting a low threshold increases recall (capturing more positives) but decreases precision (more false positives).
Q79
Which Google Cloud service is used for developing machine learning models using pre-trained APIs?
ACloud AI Platform
BBigQuery
CCloud Functions
DCloud Storage
Explanation
Cloud AI Platform offers tools for model development; BigQuery handles data analysis, Cloud Functions is for serverless computing, and Cloud Storage is for file storage.
Q80
A company needs to create a data pipeline that processes real-time events. Which Google Cloud service should they use?
ACloud Bigtable
BCloud Pub/Sub
CCloud Spanner
DCloud Functions
Explanation
Cloud Pub/Sub supports real-time messaging and streaming; Cloud Bigtable is a NoSQL datastore, Cloud Spanner is a relational database, and Cloud Functions runs event-driven code, but not as a full pipeline solution.
