Which service offers a fully managed Jupyter notebook environment?
AAI Platform Notebooks
BDataflow
CBigQuery ML
DCloud Functions
Explanation
AI Platform Notebooks provides a fully managed Jupyter notebook environment, while others serve different purposes.
Q302
A company needs to analyze large datasets efficiently. Which Google Cloud service should they use?
ACloud Storage
BBigQuery
CPub/Sub
DCloud Functions
Explanation
BigQuery is designed for efficient analysis of large datasets; the other options are for storage, messaging, or serverless execution.
Q303
You are configuring AutoML for image classification. What input format is required?
ACSV with labels
BTFRecord format
CUnlabeled images only
DImages with labels
Explanation
Images must have associated labels for supervised learning; TFRecords is not a required format and the other options are incorrect in context.
Q304
A data scientist is using BigQuery for analysis. Which feature allows for real-time data analysis?
AStreaming inserts
BBatch loading
CExporting data
DPartitioned tables
Explanation
Streaming inserts enable real-time updates, while other options are for batch processing or different data management tasks.
Q305
You are configuring a machine learning model on Vertex AI. What is the role of hyperparameter tuning?
AImproving model accuracy
BData cleaning
CDeploying the model
DLoad balancing
Explanation
Hyperparameter tuning focuses on refining parameters to enhance model performance, unlike data cleaning or deployment tasks.
Q306
What happens when a persistent disk is detached from a VM instance in Google Cloud?
AData is permanently deleted
BDisk remains available
CInstance is terminated
DSnapshot is automatically created
Explanation
The persistent disk remains available for later use, while data deletion and instance termination are incorrect outcomes.
Q307
A company needs to stream data from an IoT device to Google Cloud. Which service should they use?
ACloud Pub/Sub
BBigQuery
CCloud Functions
DCloud Storage
Explanation
Cloud Pub/Sub is designed for real-time event streaming, while others are meant for data storage or processing.
Q308
What happens when a model suffers from overfitting?
AModel performs poorly on training data
BModel generalizes well to unseen data
CModel predicts accurately on training data
DModel has high bias
Explanation
Overfitting occurs when a model is too complex, reflecting high accuracy on training but poor generalization.
Q309
You are configuring AutoML to test various models. What should you prioritize to prevent data leakage?
AUsing validation data for training
BSeparating training and test datasets
CUsing a single dataset for all tasks
DRandomly sampling validation data
Explanation
Separating training and test datasets avoids exposing the model to future data, preventing data leakage.
Q310
Which service would you use for real-time data processing in Google Cloud?
ACloud Dataflow
BCloud Storage
CCloud Firestore
DBigQuery
Explanation
Cloud Dataflow is designed for real-time data processing, while the others serve different purposes.
