Q251

A company needs to ensure that their data stored in Cloud Storage is encrypted at rest. Which configuration should they implement?

  • A Use default Google-managed keys
  • B Disable all encryption
  • C Only encrypt files after upload
  • D Manually encrypt data before upload
Explanation Using Google-managed keys automatically encrypts the data at rest; the other options either defeat encryption or complicate it unnecessarily.
Q252

What happens when you set a retention policy on a BigQuery dataset?

  • A Data cannot be deleted for a period
  • B Data is deleted immediately
  • C Only query results are retained
  • D Data is encrypted using new keys
Explanation A retention policy restricts data deletion for a specified timeframe, while the other options misrepresent BigQuery's functionality.
Q253

Which service should you use for real-time event processing?

  • A Cloud Pub/Sub
  • B Cloud Storage
  • C Cloud Functions
  • D BigQuery
Explanation Cloud Pub/Sub handles real-time message streaming, while the others focus on storage or querying.
Q254

A company needs to analyze large volumes of unstructured data stored in Cloud Storage. What is the best approach?

  • A Use Dataflow for data transformation
  • B Utilize Dataproc to run Hadoop
  • C Upload data to BigQuery directly
  • D Run AI Platform models directly
Explanation Dataproc efficiently processes large datasets with unstructured data using Hadoop, while the other options are less optimal for direct analysis.
Q255

You are configuring IAM roles for a new service account. What happens if you provide overly permissive roles?

  • A Improved security for the project
  • B Access will be denied completely
  • C Increased risk of data exposure
  • D Performance improvements for service
Explanation Overly permissive roles can lead to unauthorized access, compromising data security, while the others do not accurately reflect consequences.
Q256

Which Google Cloud service provides fully managed NoSQL databases?

  • A Cloud Firestore
  • B BigQuery
  • C Cloud SQL
  • D Compute Engine
Explanation Cloud Firestore is designed for NoSQL database needs; BigQuery is for analytics, Cloud SQL is SQL-based, and Compute Engine provides VM infrastructure.
Q257

A company needs to process streaming data from IoT devices. What GCP service is ideal?

  • A Cloud Pub/Sub
  • B Cloud Storage
  • C Dataflow
  • D Bigtable
Explanation Cloud Pub/Sub is designed for real-time messaging; Cloud Storage is for file storage, Dataflow is for processing, and Bigtable is a database service.
Q258

What happens when you enable Object Versioning in Google Cloud Storage?

  • A Old versions are deleted automatically
  • B All objects will be encrypted
  • C New versions are created for updates
  • D Only public access is granted
Explanation Enabling Object Versioning stores previous versions upon updates; old versions aren't deleted automatically, encryption isn't automatic, and access remains unchanged.
Q259

Which service is best for real-time analytics in Google Cloud?

  • A BigQuery
  • B Dataflow
  • C Cloud Logging
  • D Cloud Storage
Explanation Dataflow specializes in real-time data processing, while the others serve different purposes.
Q260

A company needs to store sensitive user data with strict compliance regulations. What should they do?

  • A Use standard Cloud Storage buckets.
  • B Encrypt data and use Key Management.
  • C Store it publicly on GCS.
  • D Utilize database without encryption.
Explanation Encryption and Key Management ensure compliance for sensitive data, unlike the other options.
