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 issue is that an important class of data (customer demographic information) was omitted from the training dataset. This is a data completeness problem: the dataset lacks relevant features needed for the recommendation task. Validity concerns whether data conforms to expected formats or business rules, accuracy concerns correctness of the recorded values, and timeliness concerns whether the data is up to date. No web search results were provided, so there are no supporting URLs.
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 inbound and outbound network traffic by allowing or denying connections based on criteria such as IP addresses, ports, and protocols. The other options address authentication, authorization, or data protection rather than network traffic 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 applied at a folder are inherited by all descendant resources in the resource hierarchy. That means projects within the folder inherit the policy, and resources within those projects also inherit it unless overridden where applicable. The policy does not automatically apply to unrelated folders or remain confined only to the folder.
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 continuously processing data as it arrives, enabling low-latency, near real-time insights. Batch processing, one-off backfills, and high-latency access are not defining characteristics of streaming analytics.
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 is a subset of artificial intelligence focused on creating new content such as text, images, audio, video, or code. It is not an umbrella term for all machine learning, nor is it limited to translation or image labeling.
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 receive notifications when cloud spending exceeds a predefined amount before the billing cycle ends, the organization should configure a budget with threshold-based alerts. Budget alerts are designed for proactive cost monitoring. The other options either reduce costs, limit resource usage, or provide forecasting, but they do not notify administrators when actual spending crosses a specified threshold.
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 jurisdiction where it is stored or processed. It is about which country's legal framework applies to the data. Individual control of personal data relates to privacy rights, encryption is a security control, and government access may be a consequence of jurisdiction but is not the defining concept of data sovereignty.
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: Rehosting (often called 'lift and shift') migrates an application to the cloud without changing its application code or architecture. Replatforming involves minor optimizations, while refactoring and reimagining require more substantial architectural and/or code changes.
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 is Google Cloud's fully managed monitoring service that provides a centralized view of cloud infrastructure, including metrics, dashboards, alerting, and uptime checks. Cloud Trace is for request latency analysis, Cloud Logging is for log collection and analysis, and Cloud Profiler is for application performance profiling.
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 is the data processing stage of the data value chain. This includes activities such as cleaning, validating, transforming, and organizing data so it is ready for analysis. Data analysis is the subsequent step where insights are extracted; collection gathers the data, and storage preserves it.
