Explanation Dataflow provides real-time data processing capabilities, unlike the others.
Q24

What happens when you set a Cloud Storage bucket to 'Uniform' access?

  • A Object-level permissions enforced
  • B Bucket-level permissions enforced
  • C No permissions allowed
  • D Public access granted

A company needs to store large volumes of structured data with low latency access. Which solution fits best?

  • A BigQuery
  • B Cloud Spanner
  • C Cloud Storage
  • D Firestore
Explanation Cloud Spanner provides strong consistency and low latency for structured data, while the others are either unstructured or not designed for high transactional workloads.
Q27

What happens when you set a GCS bucket's storage class to 'Nearline'?

  • A Lower cost, frequent access
  • B High redundancy with low latency
  • C Lower cost, infrequent access
  • D No redundancy, higher cost
Explanation Nearline storage is cheaper for infrequently accessed data, unlike the other options which describe different storage characteristics.
Q28

Which service is used for serverless event-driven applications?

  • A Cloud Functions
  • B Cloud Run
  • C App Engine
  • D Cloud Run for Anthos
Explanation Cloud Functions is specifically designed for serverless event-driven apps, while others are broader application platforms.
