Question 141
An organization finds that the amount of cash in their vending machines doesn't match the value of items sold. They have decided to upgrade their vending machines with cloud-based mobile payment systems.
How could the organization benefit from this upgrade?
A. They could relax data access permissions.
B. They could reduce their error budget overspend.
C. They could improve their perimeter security.
D. They could view data history to see transactions.
Show Answer
Correct Answer: D
Explanation: Upgrading to cloud-based mobile payment systems enables centralized, detailed transaction logging and history. This allows the organization to review and reconcile sales data against received payments, helping identify why cash amounts don’t match items sold. The other options are unrelated to resolving transaction discrepancies.
Question 142
A food delivery service needs access to real-time menu information from all partner restaurants. They also need to share customer order information with the restaurants in real time.
What should the organization use?
A. Site reliability engineering (SRE)
B. An application programming interface (API)
C. A customized machine learning model
D. A multi-regional database
Show Answer
Correct Answer: B
Explanation: The requirement is real-time, bidirectional data exchange between the food delivery service and partner restaurants. An application programming interface (API) is specifically designed to expose and consume real-time data such as menus and orders across different systems. SRE focuses on operations reliability, machine learning is not needed for data exchange, and a multi-regional database does not by itself enable system-to-system integration.
Question 143
An organization wants to search hundreds of scanned documents for key information like dates, names, and other specific words.
Why should the organization use application programming interfaces (APIs)?
A. To replace the scanned documents with an online survey
B. To ingest data in real time and encrypt unmatched words
C. To create digital versions of the documents and locate key information
D. To transform the documents into unstructured data.
Show Answer
Correct Answer: C
Explanation: APIs can connect to document processing services (such as OCR and text extraction) that convert scanned images into machine-readable text and then identify key information like dates, names, and keywords. This makes large volumes of scanned documents searchable and analyzable. Option D is incorrect because scanned documents are already unstructured; transforming them into unstructured data does not help with searching.
Question 144
Which policy helps Google Cloud keep customer data private?
A. Google tests the service availability of customer applications.
B. Google does not use customer data for advertising purposes.
C. Google migrates customer data to an offline server when a threat is detected.
D. Google does not allow customers to change encryption keys.
Show Answer
Correct Answer: B
Explanation: Google Cloud’s privacy policy explicitly states that customer data is not used for advertising or ads targeting. This policy directly supports keeping customer data private. The other options describe actions that are either incorrect, not privacy policies, or contradict Google Cloud’s actual practices.
Question 145
When an organization adopts cloud technology, how does their total cost of ownership (TCO) shift?
A. Away from cost management toward capital expenditure
B. Away from operational expenditure toward cost management
C. Away from capital expenditure toward operational expenditure
D. Away from operational expenditure toward capital expenditure
Show Answer
Correct Answer: C
Explanation: Adopting cloud technology shifts spending from upfront capital investments (servers, data centers, hardware) to ongoing, usage-based operating expenses. Cloud services are typically paid for on a pay-as-you-go basis, reducing capital expenditure and increasing operational expenditure within the total cost of ownership.
Question 146
An organization is altering their gaming product so that it is compatible with cloud technology.
What can they expect when moving from traditional technology to cloud technology?
A. No change to existing responsibilities
B. A shift toward OpEx
C. A shift toward using structured data
D. Increased hardware maintenance
Show Answer
Correct Answer: B
Explanation: Moving from traditional on‑premises technology to cloud technology typically changes cost structure. Instead of large upfront capital investments in hardware (CapEx), cloud services are consumed on a pay‑as‑you‑go basis, shifting spending toward operating expenses (OpEx). The other options are incorrect because cloud adoption does change responsibilities, does not inherently require structured data, and generally reduces rather than increases hardware maintenance.
Question 147
An organization wants a cost-effective relational database.
Which Google Cloud service should the organization use?
A. Cloud Storage
B. BigQuery
C. Cloud SQL
D. Dataflow
Show Answer
Correct Answer: C
Explanation: The requirement is a cost-effective relational database. Cloud SQL is a fully managed relational database service (MySQL, PostgreSQL, SQL Server) that minimizes operational overhead and cost. Cloud Storage is object storage, BigQuery is a data warehouse, and Dataflow is a data processing service, not relational databases.
Question 148
An organization's developers are growing increasingly frustrated by the limitations of their on-premises infrastructure.
How would they benefit from leveraging cloud technology?
A. They can expect 100% service availability.
B. They can avoid the limitations of serverless computing.
C. They can have new tools to innovate and optimize resource usage.
D. They can optimize maintenance for their on-premises infrastructure.
Show Answer
Correct Answer: C
Explanation: Cloud platforms provide a broad set of managed services, scalable infrastructure, and modern development tools that remove many on‑premises constraints. This enables developers to innovate faster and optimize resource usage through elasticity and managed services. Cloud does not guarantee 100% availability, does not avoid serverless limitations, and does not optimize maintenance of on‑premises infrastructure.
Question 149
Why should an organization consider the total cost of ownership (TCO) when moving from on-premises to the cloud?
A. To evaluate error budget
B. To understand service level availability
C. To evaluate return on investment
D. To calculate required compute power
Show Answer
Correct Answer: C
Explanation: Total cost of ownership accounts for all costs over the solution’s lifecycle (purchase, migration, operation, maintenance). When moving from on‑premises to the cloud, organizations use TCO to compare overall costs and determine whether the move delivers financial benefits, which directly supports evaluating return on investment.
Question 150
An organization notices that some of their cloud expenditures are too high.
What should the organization do to control costs?
A. Streamline the hardware procurement process to reduce costs.
B. Share cost views with the departments to establish more accountability.
C. Change the cost model from operational expenditure to capital expenditure.
D. Ensure that all could resources are tagged with a single tag.
Show Answer
Correct Answer: B
Explanation: To control cloud costs, organizations should increase transparency and accountability for usage. Sharing cost views with departments aligns with FinOps principles, making teams aware of their consumption and incentivizing optimization. The other options do not directly address cloud cost governance: hardware procurement is irrelevant to cloud spend, changing OpEx to CapEx doesn’t reduce costs, and using a single tag is neither sufficient nor a best practice for cost control.
