Question 31
A retail organization is training a model to recommend products to customers for an ecommerce website. The model was trained on previous purchases, but did not include demographic information on each buyer. What dimension of the data is responsible for the model's poor performance?
A. Validity
B. Accuracy
C. Timeliness
D. Completeness
Show Answer
Correct Answer: D
Explanation: The model’s poor performance is due to missing relevant features—demographic information—that would help personalize recommendations. This is a data completeness issue: not all necessary data attributes are present. The data can still be valid, timely, and internally accurate, but incomplete for the task.
Question 32
An organization wants to control what types of network traffic are allowed to enter and leave its network and access its applications. Which security measure should the organization use?
A. 2-Step Verification
B. Privileged access
C. Encryption keys
D. Firewall rules
Show Answer
Correct Answer: D
Explanation: Firewall rules are designed to control network traffic by allowing or blocking specific IP addresses, ports, protocols, and directions of traffic entering or leaving a network and accessing applications. The other options focus on authentication, authorization, or data protection rather than traffic flow control.
Question 33
An organization is deciding on the layout of their resource hierarchy in Google Cloud. They have several projects within a folder. What will happen when user access policies are applied to the folder?
A. The policy will be inherited by the projects in the folder but will not affect their resources.
B. The policy will be inherited by the projects and their resources within the folder.
C. The policy will be applied to all folders within the organization.
D. The policy applies to the folder only, and will not be inherited by any projects.
Show Answer
Correct Answer: B
Explanation: In Google Cloud, IAM policies follow the resource hierarchy and are inherited downward. When an IAM policy is applied at the folder level, it is inherited by all projects within that folder and by the resources contained in those projects. This enables centralized access control management across multiple projects.
Question 34
What is a defining function of streaming analytics?
A. Processing data records continuously
B. Processing data records in batches
C. Processing a one-off data backfill
D. Accessing data with high latency
Show Answer
Correct Answer: A
Explanation: Streaming analytics is defined by the continuous, real-time processing of data as it is generated or ingested. This distinguishes it from batch processing, one-off historical backfills, or high-latency data access, all of which contradict the low-latency, continuous nature of streaming systems.
Question 35
What is generative AI?
A. A machine learning model for language translation
B. A specific field of AI that can be used to create content
C. An umbrella term that includes all types of machine learning algorithms
D. An AI model for labeling images
Show Answer
Correct Answer: B
Explanation: Generative AI refers to a subset of artificial intelligence designed to create new content such as text, images, audio, or video by learning patterns from data. It is not an umbrella term for all machine learning, nor is it limited to tasks like translation or labeling, which are typically discriminative or transformational rather than content-generating.
Question 36
An organization is concerned about their cloud costs. They want to be informed when their spending exceeds a specific threshold, rather than waiting to see their bill at the end of the month. What should the organization do?
A. Pause virtual machines during non-business hours.
B. Configure a budget threshold rule and alert.
C. Adjust project resource quota policies.
D. Use historical cost data to predict future overspend.
Show Answer
Correct Answer: B
Explanation: To be informed when cloud spending exceeds a specific threshold before the end of the billing period, the organization should configure a budget threshold rule with alerts in the cloud provider’s cost management tools. This proactively notifies stakeholders as spending approaches or surpasses the defined limit, enabling timely corrective action. The other options focus on cost reduction, resource limits, or forecasting, but they do not provide real-time spending alerts.
Question 37
How does the legal concept of data sovereignty affect data?
A. Data is subject to the laws and regulations of the country where it resides.
B. A country has the right to access the data generated within its borders.
C. An individual has the right to control their personal data.
D. Data must always be encrypted in transit and at rest.
Show Answer
Correct Answer: A
Explanation: Data sovereignty is the legal principle that data is governed by the laws and regulations of the country in which it is physically stored or processed. Therefore, data must comply with that country’s legal framework. The other options describe related but distinct concepts: governmental access rights (B), individual data privacy rights (C), and technical security practices like encryption (D), none of which define data sovereignty itself.
Question 38
An organization wants to migrate a workload to the cloud without changing the application code or architecture. Which migration path describes this approach?
A. Rehosted
B. Reimagined
C. Replatformed
D. Refactored
Show Answer
Correct Answer: A
Explanation: The requirement is to migrate the workload to the cloud without changing application code or architecture. This exactly matches the rehosted migration path, commonly called lift-and-shift, where the application is moved as-is. Replatformed involves some changes, while reimagined and refactored require major redesign.
Question 39
An organization wants a centralized view of their cloud infrastructure in a fully managed system that includes uptime checks. Which Google Cloud service should they use?
A. Cloud Trace
B. Cloud Monitoring
C. Cloud Logging
D. Cloud Profiler
Show Answer
Correct Answer: B
Explanation: Cloud Monitoring provides a centralized, fully managed view of cloud resources, including metrics, dashboards, alerting, and built-in uptime checks. The other options focus on specific aspects (tracing, logging, or profiling) rather than comprehensive infrastructure monitoring.
Question 40
An organization is transforming their raw data into a format that can be used to derive business insights. Which step of the data value chain does this action represent?
A. Data analysis
B. Data collection
C. Data storage
D. Data processing
Show Answer
Correct Answer: D
Explanation: Transforming raw data into a usable format for deriving business insights corresponds to data processing. This stage includes cleaning, structuring, aggregating, and converting data so it is ready for analysis. Data collection gathers the data, storage holds it, and analysis comes after processing to extract insights.
