Q411

You are configuring a machine learning model using Vertex AI. What happens when you set 'enable_early_stopping' to true?

  • A Model trains indefinitely
  • B Training stops at optimal performance
  • C More data must be collected
  • D Model accuracy decreases
Explanation Setting 'enable_early_stopping' allows the model to halt training when it reaches optimal performance.
Q412

Which Google Cloud service is best for large-scale machine learning model training?

  • A AI Platform
  • B Cloud Functions
  • C Cloud Pub/Sub
  • D Compute Engine
Explanation AI Platform is specifically designed for large-scale ML model training, while the others serve different purposes.
Q413

You are configuring a VPC with a private subnet. Which of the following is NOT accessible directly from the Internet?

  • A Cloud SQL instance
  • B VMs in private subnet
  • C NAT Gateway
  • D Load balancer in public subnet
Explanation VMs in a private subnet do not have direct Internet access, while the others can be accessed.
Q414

A company needs to analyze logs stored in Cloud Storage efficiently. What is the best approach?

  • A Use Cloud Bigtable directly
  • B Load logs into BigQuery
  • C Analyze logs in Cloud Storage directly
  • D Use Dataflow for real-time analysis
Explanation Loading logs into BigQuery allows efficient analysis using SQL, whereas the other options are less efficient or not feasible.
Q415

Which service would you use for data warehousing on Google Cloud?

  • A BigQuery
  • B Cloud Storage
  • C Cloud Datastore
  • D Cloud Functions
Explanation BigQuery is specifically designed for analytics and data warehousing, while others serve different purposes.
Q416

A company needs to collect and process streaming data in real-time. Which Google Cloud service is the best choice?

  • A Cloud Pub/Sub
  • B Cloud Spanner
  • C Cloud SQL
  • D Cloud Firestore
Explanation Cloud Pub/Sub is tailored for real-time messaging and streaming data, unlike the others which focus on storage or databases.
Q417

You are configuring a machine learning model in AI Platform. What happens when you set a lower value for the learning rate?

  • A Faster convergence of model
  • B Stability in training process
  • C Possibly slower convergence
  • D Prevents overfitting immediately
Explanation A lower learning rate might lead to slower convergence, requiring more epochs to reach optimal performance.
Q418

Which Google Cloud service is best for handling large, real-time streams of data?

  • A Cloud Dataflow
  • B Cloud Storage
  • C Cloud Functions
  • D BigQuery
Explanation Cloud Dataflow is designed for processing real-time data streams, while Cloud Storage is for storage, Cloud Functions for serverless compute, and BigQuery for analytics.
Q419

A company needs to share sensitive dataset access with third-party users securely. Which approach should they take?

  • A IAM roles and permissions
  • B Public access buckets
  • C SSH tunnels
  • D API keys
Explanation IAM roles provide fine-grained access control, while public access, SSH tunnels, and API keys do not ensure proper security.
Q420

You are configuring a Cloud Pub/Sub topic retention policy. What happens if a message is unacknowledged after its retention duration?

  • A Message is automatically deleted
  • B Message is sent again
  • C Message remains indefinitely
  • D Message is archived
Explanation Unacknowledged messages after the retention period are discarded, while the other options do not accurately reflect Cloud Pub/Sub behavior.
