What happens when a model is overfitting on training data?
AHigh accuracy on training data
BLow accuracy on validation data
CBalanced performance on both
DIncreased training time required
Explanation
Overfitting typically leads to high training accuracy but low validation accuracy due to memorization of noise in training data.
Q262
Which Google Cloud service is best for managing ML model lifecycle?
AAI Platform
BCloud Functions
CCloud Firestore
DBigQuery
Explanation
AI Platform provides tools for model training, deployment, and versioning, while others serve different purposes.
Q263
A company needs real-time predictions for customer insights. Which should they use?
ABatch Processing with BigQuery
BAI Platform Prediction
CCloud Pub/Sub
DDataflow
Explanation
AI Platform Prediction facilitates real-time inference, while others are focused on data flow or batch processes.
Q264
You are configuring a Neural Network in TensorFlow. What happens when the learning rate is set too high?
AIt converges faster
BIt may diverge
CIt improves accuracy
DIt trains slower
Explanation
A high learning rate can cause the model to overshoot minima, leading to divergence rather than convergence.
Q265
Which service is best for deploying machine learning models at scale?
AAI Platform
BCloud Functions
CBigQuery
DCloud Dataflow
Explanation
AI Platform is specifically designed for model deployment, whereas the others serve different purposes.
Q266
A company needs to process large batches of data daily and requires low latency responses. Which Google Cloud service should they use?
ACloud Pub/Sub
BCloud Storage
CBigQuery
DDataflow
Explanation
Dataflow can process batches with low latency, while the others are less optimized for this specific use case.
Q267
What happens when you use a pre-trained TensorFlow model that exceeds the memory limit of your VM?
AModel fails to load
BAuto-scaling adjusts resources
CModel runs slower automatically
DIt's cached in memory
Explanation
The model cannot load if it exceeds the VM's memory capacity; the other options do not accurately describe the behavior in this scenario.
Q268
Which Google Cloud service helps in real-time data streaming?
ACloud Functions
BCloud Pub/Sub
CCloud Run
DBigQuery
Explanation
Cloud Pub/Sub is designed for real-time messaging, while the others serve different purposes.
Q269
A company needs to run machine learning models on large datasets while keeping costs low. Which service should they choose?
AAI Platform Notebooks
BBigQuery ML
CTensorFlow Serving
DCloud Dataflow
Explanation
BigQuery ML allows efficient ML on large datasets directly in BigQuery, unlike the other options that are more resource-intensive.
Q270
You are configuring a machine learning model for long-term predictions. What happens when you don't account for seasonality in your data preprocessing?
AReduced model complexity
BImproved accuracy
CUnderfitting of predictions
DOverfitting of predictions
Explanation
Ignoring seasonality may lead to underfitting, as the model won't capture periodic patterns.
