Question 51
An organization wants to build custom machine learning models. They require a managed platform that provides services to gather data, build models, and then deploy and monitor those models. Which service should they use?
A. Document AI
B. Natural Language API
C. Kubernetes Engine
D. Vertex AI
Show Answer
Correct Answer: D
Explanation: Vertex AI is a fully managed machine learning platform that supports the entire ML lifecycle, including data preparation, model building and training, deployment, and ongoing monitoring. The other options are either pre-built AI APIs or general infrastructure services and do not provide end-to-end managed ML capabilities.
Question 52
An organization is developing applications by using Kubernetes. They want their teams to spend more time developing rather than managing clusters. Which Google Cloud service should the organization choose?
A. GKE Autopilot
B. Compute Engine
C. Cloud Run
D. GKE Standard
Show Answer
Correct Answer: A
Explanation: GKE Autopilot is a fully managed Kubernetes mode where Google handles cluster infrastructure, node provisioning, scaling, and maintenance. This minimizes operational overhead so teams can focus on application development rather than managing Kubernetes clusters. Compute Engine requires self-managed clusters, Cloud Run is not Kubernetes-based, and GKE Standard requires more hands-on cluster management.
Question 53
An organization has an ecommerce application that requires a cost-effective, transactional database. The application will only serve customers in a single region. Which service should they use?
A. BigQuery
B. Cloud Bigtable
C. Cloud Spanner
D. Cloud SQL
Show Answer
Correct Answer: D
Explanation: The application needs a cost-effective, transactional (OLTP) database and serves users in a single region. Cloud SQL is a managed relational database optimized for transactional workloads and regional deployments at lower cost. BigQuery is for analytics, Cloud Bigtable is a NoSQL system not suited for relational transactions, and Cloud Spanner is a globally distributed database that is more complex and expensive than needed for a single-region ecommerce app.
Question 54
An organization is using Compute Engine and wants to receive sustained-use discounts. What should the organization do?
A. Choose preemptible or spot instances when creating virtual machines.
B. Choose low-powered virtual machines.
C. Nothing. Sustained use discounts are automatically applied.
D. Commit to virtual machine usage for a one or three-year period.
Show Answer
Correct Answer: C
Explanation: In Google Compute Engine, sustained-use discounts are applied automatically when a VM runs for a significant portion of the billing month. No special VM type, sizing choice, or long-term commitment is required. Preemptible/spot VMs and committed use contracts are separate discount models, not sustained-use discounts.
Question 55
An organization has migrated several large databases to the cloud. It wants to increase the value of its data, improve cost controls and strengthen regulatory compliance. What should the organization do?
A. Delete data stored for over a year.
B. Export relational data to modern NoSQL databases.
C. Create monthly reports on data access and uses.
D. Establish an effective data governance program.
Show Answer
Correct Answer: D
Explanation: Establishing an effective data governance program addresses all stated goals: it increases data value through standards and stewardship, improves cost control via lifecycle and usage management, and strengthens regulatory compliance through policies, controls, and auditing. The other options are partial or tactical and do not comprehensively meet these objectives.
Question 56
In Google’s cloud security model, how does availability contribute to a robust security posture for data?
A. By restricting data access to authorized users
B. By ensuring data meets industry standards
C. By checking that data is accurate and trustworthy
D. By ensuring data is reliable and accessible
Show Answer
Correct Answer: D
Explanation: In Google’s cloud security model, availability focuses on ensuring systems and data remain reliable and accessible when needed. This supports business continuity and resilience against failures or outages. The other options map to different security principles: A to confidentiality, C to integrity, and B to compliance/standards rather than availability.
Question 57
An organization is running critical workloads in production and requires a Google Cloud support service with fast response times and a dedicated Technical Account Manager. Which customer care service level should the organization choose?
A. Enhanced
B. Basic
C. Premium
D. Standard
Show Answer
Correct Answer: C
Explanation: Organizations running critical production workloads that require fast response times and a dedicated Technical Account Manager should choose Google Cloud Premium Support. Premium Support offers 24/7 assistance, the fastest SLA response times, proactive guidance, and a dedicated TAM—features not included in Basic, Standard, or Enhanced support tiers.
Question 58
A real estate organization processes photos of properties uploaded by their agents to an internal application. They must manually check and remove photos that contain personally identifiable information like passports and credit cards. They want a solution that their developer can use to integrate with their app as quickly as possible. Which solution should they use?
A. Pre-trained APIs
B. AutoML
C. Custom training
D. BigQuery ML
Show Answer
Correct Answer: A
Explanation: They need the fastest way to integrate image analysis for detecting personally identifiable information in photos. Pre-trained APIs (such as Cloud Vision API) are ready to use, require no model training, and can immediately detect sensitive content like passports or credit cards. AutoML and custom training require data preparation and training time, and BigQuery ML is designed for structured data rather than image processing.
Question 59
An organization has a large archive of unstructured data, including video and audio files. Which storage solution should the organization use?
A. Cloud Spanner
B. Cloud Storage
C. Cloud Bigtable
D. Cloud SQL
Show Answer
Correct Answer: B
Explanation: Cloud Storage is the correct choice because it is designed for large-scale unstructured data such as video and audio files. It provides highly scalable, durable, and cost-effective object storage with multiple storage classes suitable for archiving. The other options—Cloud Spanner, Cloud Bigtable, and Cloud SQL—are database services optimized for structured or semi-structured data and transactional or low-latency workloads, not for storing large unstructured media files.
Question 60
An organization wants to run their custom application in the cloud in a flexible and scalable way without managing any infrastructure. Which service model should they use?
A. Infrastructure as a service
B. Platform as a service
C. Software as a service
D. Network as a service
Show Answer
Correct Answer: B
Explanation: Platform as a Service (PaaS) is designed for running custom applications without managing underlying infrastructure. The cloud provider handles servers, storage, networking, OS, and runtime, while the organization focuses on application code. IaaS still requires infrastructure management, SaaS does not support deploying custom applications, and NaaS focuses only on networking services.
