Q141

What happens when you set your Cloud Pub/Sub subscription to 'acknowledge' only after a delay?

  • A Messages are reprocessed immediately.
  • B Messages are deleted after the delay.
  • C Messages will not be sent again.
  • D Messages may be redelivered after delay.
Explanation Delayed acknowledgment can lead to message redelivery based on ack deadline settings.
Q142

Which service should you use for hosting machine learning models at scale?

  • A Cloud Run
  • B Cloud Functions
  • C AI Platform
  • D App Engine
Explanation AI Platform is specifically designed for ML model deployment, whereas others are general-purpose compute services.
Q143

A company needs to analyze large datasets stored in BigQuery regularly. What is the best way to automate this?

  • A Cloud Functions
  • B Cloud Scheduler and Dataflow
  • C Compute Engine VMs
  • D BigQuery Storage API
Explanation Cloud Scheduler can trigger Dataflow jobs to automate analysis on regular schedules, which fits requirements.
Q144

What happens when you set a high learning rate in a neural network training process?

  • A Slower convergence
  • B Faster convergence
  • C Easier overfitting
  • D Poor accuracy
Explanation A high learning rate can cause the model to bounce around the optimal minimum, leading to poor performance.
Q145

Which Google Cloud service is best for analyzing large datasets using SQL?

  • A BigQuery
  • B Cloud Datastore
  • C Cloud Functions
  • D Cloud Spanner
Explanation BigQuery is designed specifically for large SQL analytics, while the others serve different purposes.
Q146

A company needs to deploy machine learning models that automatically scale based on incoming request volume. Which Google Cloud solution should they use?

  • A AI Platform Prediction
  • B Compute Engine
  • C App Engine
  • D Cloud Functions
Explanation AI Platform Prediction is tailored for scalable ML model deployment, unlike the other options.
Q147

You are configuring a Dataflow pipeline. What happens when you set the 'maxNumRecords' option to a low value?

  • A Dataflow ignores all records.
  • B The pipeline processes all records.
  • C Only a limited number of records processed.
  • D Pipeline terminates with an error.
Explanation Setting 'maxNumRecords' throttles the processing to a specified limit, preserving resources.
Q148

A data scientist needs to deploy a machine learning model that can process incoming data in real-time. Which Google Cloud service should they use?

  • A Cloud Functions
  • B Cloud Dataflow
  • C Cloud Run
  • D Vertex AI
Explanation Cloud Dataflow is designed for real-time stream processing, while the other options serve different use cases.
Q149

You are configuring a training job in Vertex AI and need to avoid overfitting. What is a recommended approach?

  • A Increase training dataset size
  • B Reduce model complexity
  • C Use dropout layers
  • D All of the above
Explanation All listed approaches are effective in preventing overfitting during machine learning training.
Q150

What happens when a GCP service account key is compromised?

  • A Access is immediately revoked
  • B Account receives a warning
  • C Potential unauthorized access occurs
  • D Nothing happens, it's secure
Explanation Unauthorized access can occur if a service account key is compromised, making it critical to handle them securely.
