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 Google Cloud's managed end-to-end machine learning platform. It supports the full ML lifecycle, including data preparation, model training, hyperparameter tuning, deployment, and monitoring. Document AI and Natural Language API are specialized AI services with prebuilt capabilities, while Google Kubernetes Engine is a container orchestration platform rather than a managed ML lifecycle service.
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 the fully managed mode of Google Kubernetes Engine that minimizes cluster administration by automatically managing nodes, scaling, upgrades, and infrastructure, allowing development teams to focus on building Kubernetes applications. Compute Engine requires self-management, Cloud Run is serverless rather than a Kubernetes cluster service, and GKE Standard requires more hands-on cluster and node 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: Cloud SQL is the best fit for a cost-effective transactional (OLTP) relational database serving users in a single region. BigQuery is an analytics data warehouse, Bigtable is a NoSQL wide-column database, and Cloud Spanner is designed for globally distributed, horizontally scalable relational workloads and is generally more costly than needed for a single-region ecommerce application.
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: Sustained use discounts for eligible Compute Engine resources are applied automatically based on usage during the billing month. They do not require any commitment. One- or three-year commitments are for committed use discounts, while Spot/preemptible instances and smaller VM sizes are separate cost-saving choices, not requirements for 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: An effective data governance program establishes policies, ownership, lifecycle management, security, quality, access controls, retention, and compliance. These practices increase the value of data, improve cost management through proper lifecycle and storage governance, and strengthen regulatory compliance. The other options address only narrow aspects or may introduce unnecessary risk without governance.
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 the CIA triad used in cloud security, availability means ensuring systems and data are reliable and accessible when needed. Restricting access is confidentiality, checking accuracy is integrity, and meeting industry standards relates to compliance 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: Premium Customer Care is intended for organizations running mission-critical production workloads. It provides the fastest response times, 24/7 support, proactive guidance, and includes a designated Technical Account Manager (TAM). Enhanced, Standard, and Basic do not include a dedicated TAM.
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: The best choice is Pre-trained APIs because the requirement is to integrate image analysis into an application as quickly as possible. Google Cloud's pre-trained Vision capabilities can detect documents, text, and other image features without collecting training data or building a custom model. AutoML and custom training require dataset preparation and model training, while BigQuery ML is intended for ML on structured data rather than image analysis.
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 service for storing large volumes of unstructured data such as video and audio files. It is Google Cloud's scalable object storage designed for media, archives, backups, and other binary objects. Cloud Spanner and Cloud SQL are databases for structured relational data, while Cloud Bigtable is a NoSQL wide-column database for structured, high-throughput workloads rather than object storage.
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 deploying and running custom applications without managing the underlying infrastructure. The cloud provider manages servers, storage, networking, operating systems, and often the runtime, while the customer focuses on the application. IaaS still requires infrastructure management, SaaS is for consuming finished applications rather than deploying custom ones, and NaaS provides networking services rather than an application hosting platform.
