Questions 101–110 of 486

Q101

A company needs to analyze big data and wants to avoid a long data processing time. What should they consider using?

  • A Custom-built database
  • B Cloud Bigtable
  • C Dataproc
  • D Cloud Functions
Explanation Dataproc enables fast processing of large datasets using Apache Spark; others are less suited for this scale.
Q102

You are configuring IAM roles for a team. What happens if you assign both Editor and Viewer roles to a user?

  • A User will have Editor permissions only.
  • B User will have Viewer permissions only.
  • C User will have combined permissions.
  • D This will cause a permissions error.
Explanation The user will inherit all permissions from both roles, as IAM roles are additive.
Q103

Which Google Cloud service allows you to run containers without managing the underlying infrastructure?

  • A Google Kubernetes Engine
  • B Cloud Functions
  • C Cloud Run
  • D App Engine
Explanation Cloud Run specifically allows running containers serverlessly, while others manage infrastructure differently.
Q104

A company needs to process large datasets on a regular schedule while ensuring minimal manual intervention. Which service should they use?

  • A Cloud Dataflow
  • B Cloud Functions
  • C Cloud Run
  • D BigQuery
Explanation Cloud Dataflow is designed for scheduled, automated data processing, while others are not primarily for this use case.
Q105

What happens when you set a Cloud Storage bucket's access control to 'uniform'?

  • A Only object-level permissions apply.
  • B Bucket and objects share the same permissions.
  • C Permissions automatically expire after 30 days.
  • D Individual objects can be managed separately.
Explanation Uniform control means both bucket and objects inherit the same permissions, unlike 'fine-grained' control.
Q106

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

  • A Cloud Dataflow
  • B Cloud Storage
  • C BigQuery
  • D Cloud Pub/Sub
Explanation Cloud Dataflow is designed for stream processing, while others focus on storage or querying.
Q107

A company needs to secure its data in BigQuery. What is the best practice?

  • A Public Access
  • B Access Control Lists (ACLs)
  • C IAM Roles
  • D Export Data to Cloud Storage
Explanation IAM Roles provide fine-grained access controls, which is essential for security.
Q108

What happens when two users attempt to write to the same Cloud Firestore document simultaneously?

  • A First write is applied.
  • B Last write overwrites previous.
  • C Transaction conflict occurs.
  • D Both writes succeed without issues.
Explanation Firestore enforces ACID transactions, so a conflict is detected on simultaneous writes.
Q109

Which service is optimal for real-time data processing?

  • A Cloud Dataflow
  • B Cloud Storage
  • C Cloud Functions
  • D BigQuery
Explanation Cloud Dataflow offers real-time data pipeline processing, while others serve different purposes like storage or batch processing.
Q110

A company needs to analyze streaming data from IoT devices. Which solution is suitable?

  • A Cloud Pub/Sub with BigQuery
  • B Cloud SQL with Cloud Run
  • C Cloud Storage for archiving
  • D Firebase Realtime Database
Explanation Cloud Pub/Sub can ingest real-time data, making it ideal for IoT data processing with BigQuery for analytics.
