You are configuring a machine learning model training in Google Cloud. What happens when you set a lower learning rate?
AFaster convergence to optimal solution
BModel may underfit data
CHigher chance of overshooting minima
DIncreased training time
Explanation
A lower learning rate typically increases training time, as the model updates more gradually; the other options describe effects not associated with lower rates.
Q412
Which service should you use for visualizing data?
ABigQuery
BData Studio
CCloud Pub/Sub
DCloud Functions
Explanation
Data Studio is designed specifically for data visualization, while the others serve different purposes.
Q413
A company needs to register their domain with Google Cloud. Which service should they use?
ACloud DNS
BGoogle Domains
CApp Engine
DCloud Storage
Explanation
Google Domains is the correct service for domain registration, while Cloud DNS is for DNS management.
Q414
You are configuring machine types for your VM instance. What happens when you select a custom machine type?
AYou can only use predefined types.
BYou can set any number of vCPUs.
CYou are restricted to standard configurations.
DYou can choose vCPUs and memory.
Explanation
Selecting a custom machine type allows configuration of both vCPUs and memory size based on requirements.
Q415
Which service is designed for building conversational interfaces?
ADialogflow
BBigQuery
CCloud Spanner
DCompute Engine
Explanation
Dialogflow specifically focuses on natural language understanding, while the other services serve different purposes.
Q416
A company needs to analyze large datasets efficiently. Which Google Cloud service should they use?
ACloud Functions
BCloud Pub/Sub
CBigQuery
DCloud Storage
Explanation
BigQuery is optimized for large dataset analysis, unlike the other choices.
Q417
You are configuring an AutoML model. What happens if your dataset is too small?
AModel accuracy improves
BModel fails to train
CModel overfits easily
DModel is faster to train
Explanation
A small dataset can lead to overfitting, making the model unreliable on new data, unlike training failures or improvements.
Q418
Which service is best for deploying machine learning models?
AAI Platform
BCloud Functions
CBigQuery ML
DFirestore
Explanation
AI Platform is designed for ML model deployment, while others serve different purposes.
Q419
A company needs to automatically scale its applications based on traffic changes. What should they implement?
AStatic Load Balancer
BAuto Scaling Groups
CCloud Functions
DCloud Storage
Explanation
Auto Scaling Groups adjust resources based on demand, while others do not provide this functionality.
Q420
What happens when you set an IAM role binding at the organization level?
AApplies to all projects
BOnly to selected users
COverrides project roles
DOnly applies to storage buckets
Explanation
Organization-level bindings affect all projects within that organization; others misrepresent how IAM roles function.
