Q291

What happens when you set up a VPC using a private IP range?

  • A Public resources are deployable
  • B Instances lose external IPs
  • C Canada is selected as location
  • D No network traffic restriction exists
Explanation Setting a private IP range means VM instances cannot communicate directly over the internet without a NAT, while the other options are misleading regarding IP assignments and locations.
Q292

Which service is best for building machine learning models?

  • A AI Platform
  • B Cloud Functions
  • C Cloud Spanner
  • D Compute Engine
Explanation AI Platform is specifically designed for ML models, while others serve different purposes.
Q293

A company needs to process large amounts of streaming data. Which Google Cloud service should they use?

  • A BigQuery
  • B Pub/Sub
  • C Cloud Storage
  • D Dataflow
Explanation Dataflow is designed for stream processing; Pub/Sub is for messaging, not processing.
Q294

You are configuring IAM roles for a new project. What happens if a user has multiple conflicting roles?

  • A Only the highest role's permissions apply.
  • B All permissions are aggregated.
  • C The user gains no permissions.
  • D Permissions are denied.
Explanation Google Cloud combines permissions from all assigned roles for a user.
Q295

Which service is best for stream processing in GCP?

  • A Dataflow
  • B BigQuery
  • C Cloud Functions
  • D Cloud Storage
Explanation Dataflow is specifically designed for stream processing, while others serve different purposes.
Q296

A company needs to ensure their data in BigQuery is automatically encrypted. What should they enable?

  • A Customer Managed Keys
  • B Data Loss Prevention
  • C Default Encryption
  • D External Tables
Explanation BigQuery automatically encrypts data at rest by default; manual key management is optional.
Q297

You are configuring a DataStore. What happens if you exceed your write capacity?

  • A Writes are automatically queued
  • B The system throws an error
  • C All writes are dropped
  • D Latency is drastically increased
Explanation Exceeding write capacity results in write errors, requiring proper management to avoid them.
Q298

Which Google Cloud service is used for event-driven asynchronous messaging?

  • A Cloud Pub/Sub
  • B Cloud Functions
  • C Cloud Storage
  • D Cloud SQL
Explanation Cloud Pub/Sub is specifically designed for asynchronous messaging, whereas the others serve different purposes.
Q299

A company needs to run a machine learning model at scale on new data daily. What is the best approach?

  • A Manual model training
  • B Scheduled batch processing
  • C Real-time processing using Dataflow
  • D Using a desktop application
Explanation Dataflow allows real-time processing and scaling, which is ideal for daily model updates.
Q300

You are configuring a Virtual Private Cloud (VPC) for your application. What happens if two subnets in the same VPC have overlapping IP ranges?

  • A It works without issues.
  • B It causes routing conflicts.
  • C Only one subnet functions.
  • D Both subnets are deleted.
Explanation Overlapping IP ranges lead to routing conflicts, preventing proper network communication.
