Question 1
An organization has petabytes of data gathered from a wide range of sources. They want to use the data for strategic analysis and to guide business decisions. What type of service should they use?
A. Object store
B. Non-relational document database
C. Data warehouse
D. Relational transactional database
Show Answer
Correct Answer: C
Explanation: A data warehouse is designed to consolidate large volumes of data from multiple sources for analytics, reporting, and business intelligence. It supports strategic analysis and decision-making, unlike transactional databases, document databases, or object storage, which serve different primary purposes.
Question 2
An organization is deploying applications to the cloud using platform as a service.
In the shared responsibility model, what remains the responsibility of the customer organization?
A. Operations
B. Data access policies
C. Physical security
D. Network security
Show Answer
Correct Answer: B
Explanation: In the Platform as a Service (PaaS) shared responsibility model, the cloud provider manages the underlying infrastructure, including physical security, networking infrastructure, and platform operations. The customer remains responsible for their applications, identities, and data governance, including defining and enforcing data access policies.
Question 3
An organization wants to deploy new workloads to the cloud but must keep some systems on-premises for compliance reasons. Both environments must be managed centrally. Which type of environment should the organization use?
A. Virtual machine environment
B. Multi cloud environment
C. Hybrid cloud environment
D. Container environment
Show Answer
Correct Answer: C
Explanation: A hybrid cloud environment combines on-premises infrastructure with public or private cloud services, allowing workloads to run in both locations while being managed centrally. This matches the requirement to keep some systems on-premises for compliance while deploying new workloads to the cloud.
Question 4
An organization is using new technologies to change its business processes and culture to develop new customer experiences and adapt to market dynamics.
What is the name of this approach?
A. Digital transformation
B. Data center migration
C. Operations optimization
D. User personalization
Show Answer
Correct Answer: A
Explanation: Digital transformation is the organization-wide adoption of digital technologies to fundamentally change business processes, organizational culture, and customer experiences in order to adapt to changing market conditions and create new value.
Question 5
An organization wants to refactor their application by using a microservices architecture when migrating to the cloud. Which benefit would this action provide?
A. The refactored application is more efficient and scalable.
B. No code changes will be required.
C. This migration pattern provides the fastest path to the cloud.
D. The application will become PCI-DSS compliant by default.
Show Answer
Correct Answer: A
Explanation: Refactoring to a microservices architecture typically improves scalability, agility, and resource efficiency because services can be developed, deployed, and scaled independently. It does require code changes, is not the fastest migration approach compared to rehosting (lift-and-shift), and does not automatically provide PCI-DSS compliance.
Question 6
An organization is planning to deploy a new workload to Google Cloud. They need an accurate estimate of the likely costs of running the workload. How should the organization create this estimate?
A. Use the Google Cloud Pricing Calculator.
B. Deploy workload to test environment to observe costs.
C. Use historic costs of an existing similar workload.
D. Refer to pricing information and manually calculate an estimate.
Show Answer
Correct Answer: A
Explanation: The Google Cloud Pricing Calculator is the recommended tool for estimating the cost of a planned Google Cloud workload. It models service configurations, regions, and expected usage to produce a cost estimate. Deploying a test workload incurs unnecessary costs, historical workloads may not match the new deployment, and manual calculations are more error-prone and less comprehensive.
Question 7
An organization supplies electric car chargers in a nationwide network. They store customer and charging data in BigQuery. They want to efficiently upgrade and maintain their network to reduce waste and achieve their sustainability goals. How can Google Cloud services help the organization?
A. Secure data access by using Identity and Access Management.
B. Provide access to third-party developers by creating an API using Apigee.
C. Create a model in BigQuery to predict future maintenance schedules.
D. Move data from BigQuery to Cloud Storage to reduce storage costs.
Show Answer
Correct Answer: C
Explanation: The organization already stores operational data in BigQuery and wants to upgrade and maintain its charging network efficiently while reducing waste. BigQuery ML can build predictive models directly in BigQuery to forecast maintenance needs from historical charging and equipment data, enabling predictive maintenance and better resource utilization. IAM (A) addresses security rather than maintenance optimization, Apigee (B) is for API management, and moving data to Cloud Storage (D) is a storage cost optimization that does not help predict maintenance or improve sustainability.
Question 8
What is the purpose of an application programming interface (API)?
A. To provide a set of instructions that allow computer programs to communicate with each other
B. To provide cloud plugins for integrated development environments
C. To connect networks from different cloud providers
D. To manage multiple containerized workloads
Show Answer
Correct Answer: A
Explanation: An application programming interface (API) defines a standardized way for software components or applications to communicate and interact by exposing functions, operations, or data. It is not specifically for IDE plugins, inter-cloud network connectivity, or container workload management.
Question 9
A financial organization has many customers who close their accounts every year. The organization wants to use data and AI to identify at-risk customers, so they can retain customers by offering discounts and improved services. What should the organization do?
A. Create a dashboard of previous customers that have exited, and look for obvious correlations in the visualization.
B. Create a ML model based on the demographics and activities of previous customers that exited.
C. Create a survey for all customers to identify their current level of satisfaction.
D. Create a report based on last year’s customer feedback.
Show Answer
Correct Answer: B
Explanation: The organization's goal is to identify customers at risk of closing their accounts before they do. A supervised machine learning model trained on historical data (such as demographics and customer activity) with past customer exits as the target can learn patterns associated with churn and predict which current customers are likely to leave. Dashboards, surveys, and reports provide descriptive insights but do not deliver predictive identification of at-risk customers.
Question 10
An organization is building advanced machine learning models in Google Cloud by using TensorFlow. They want to develop their models faster with purpose-built hardware. Which solution should the organization use?
A. TPUs
B. CPUs
C. CPUs
D. GPUs
Show Answer
Correct Answer: A
Explanation: Google Cloud TPUs (Tensor Processing Units) are purpose-built accelerators designed by Google specifically to speed up TensorFlow training and inference workloads. Compared with general-purpose CPUs and even GPUs, TPUs are the purpose-built hardware referenced in the question for faster TensorFlow model development.
