A company needs to train a model on a large dataset but is limited on disk space. What Google Cloud service can help?
ACloud Storage
BBigQuery
CCloud Functions
DCloud SQL
Explanation
BigQuery allows querying large datasets without extensive local storage.
Q312
You are configuring a machine learning model for inferencing. What happens when you set a lower 'confidence threshold'?
AFewer predictions are made.
BMore predictions are returned.
CAll predictions are ignored.
DAccuracy improves instantly.
Explanation
A lower confidence threshold increases the number of predictions returned, potentially including less certain ones.
Q313
Which service is used for managing machine learning lifecycle in Google Cloud?
AAI Platform
BCloud Functions
CDataflow
DCompute Engine
Explanation
AI Platform provides tools for model management; others focus on different functions.
Q314
A company needs to continuously analyze streaming data. Which Google Cloud service should they use?
ACloud Bigtable
BPub/Sub
CCloud SQL
DCloud Functions
Explanation
Pub/Sub handles real-time messaging; others are less suited for streaming.
Q315
You are configuring a ML model and see unusual results. What happens if you alter the learning rate?
AConvergence time increases only
BModel performance may improve
CTraining data becomes irrelevant
DLoss function errors reduce
Explanation
Adjusting the learning rate can optimize learning; other options misrepresent effects of learning rate changes.
Q316
Which Google Cloud service is optimized for time-series data analysis?
ABigQuery
BCloud Spanner
CCloud Functions
DCloud Storage
Explanation
BigQuery is designed for analytics, especially time-series data, while others serve different primary functions.
Q317
A company needs to deploy machine learning models at scale and minimize latency for predictions. Which Google Cloud service should they use?
AAI Platform Prediction
BDataflow
CFirestore
DApp Engine
Explanation
AI Platform Prediction is specifically designed for model deployment and low-latency predictions, unlike the others.
Q318
You are configuring access to a Cloud Storage bucket for a machine learning application. What happens when you apply a 'deny all' policy to the IAM role?
AAll users can access the bucket
BNo users can access the bucket
COnly certain users can access
DIt has no effect on access
Explanation
A 'deny all' policy completely restricts access, while the others misrepresent the IAM behavior under deny policies.
Q319
Which service is ideal for real-time data processing?
ACloud Pub/Sub
BCloud Storage
CCloud Bigtable
DCloud Functions
Explanation
Cloud Pub/Sub supports real-time messaging, unlike the others.
Q320
A company needs to securely share data between two Google Cloud projects. What should they use?
ACloud Interconnect
BVPC Peering
CShared VPC
DCloud IAM roles
Explanation
Shared VPC allows for secure resource sharing between projects, while others do not specifically provide this feature.
