Vertex AI Matching Engine

Question 3

A bank is evaluating Google Cloud generative AI offerings to build an internal document-processing application. Leadership requires that the solution support grounding responses in the bank's own document repository and provide enterprise controls such as IAM-based access and audit logging. Which two Google Cloud offerings should the bank consider to meet these requirements? (Choose two.)

Accepted Answer

Vertex AI Search with enterprise data stores for grounding. Vertex AI Search with enterprise data stores and Vertex AI with Gemini grounding both let an organization ground model responses in its own documents while operating under Cloud IAM and audit logging. Those two offerings align with the bank's dual requirement of private-repository grounding and enterprise governance for a custom application, whereas prototyping tools and end-user assistant products do not.

Answer

Gemini for Google Workspace

Answer

Google AI Studio with the Gemini API

Answer

Gemini Enterprise as a standalone assistant for analysts

Question 4

A logistics company needs an assistant that answers driver questions about shipment status. The answers must reflect live data from an operational database and must include citations so dispatchers can verify each claim. The company wants a managed Google Cloud capability rather than custom retrieval code. Which capability should they use?

Accepted Answer

Grounding with Vertex AI Search data stores connected to the operational data, used through Vertex AI Agent Builder.. The requirements are live data plus citations, delivered through a managed capability. Grounding with Vertex AI Search data stores retrieves from indexed enterprise sources and returns citations, and Agent Builder provides the managed orchestration layer that surfaces them. Temperature changes, manual exports, and fine-tuning cannot supply live lookups or verifiable source references, so they fail the scenario regardless of model quality.

Answer

Increasing the Gemini model's temperature setting so responses draw more broadly on the model's internal knowledge.

Answer

Exporting the operational database nightly to a Cloud Storage bucket and pasting relevant rows into each prompt manually.

Answer

Fine-tuning the Gemini model on historical shipment records so it memorizes typical status patterns.

Question 5

A financial analyst needs to quickly extract key figures and summarize insights from a 200-page earnings report PDF. They want to use a Google Cloud generative AI model that can process long documents and answer questions. Which Gemini model capability should they leverage?

Accepted Answer

Gemini's long context window. Gemini's long context window is designed to handle very large inputs, such as a 200-page PDF, in a single request. This allows the analyst to ask questions and extract insights without manual segmentation. Other features like function calling, multimodality, or grounding address different needs and do not solve the core challenge of processing a long document.

Answer

Gemini's multimodal input

Answer

Gemini's function calling

Answer

Gemini's grounding with Google Search

Question 6

A media company is evaluating Google Cloud generative AI offerings to build a production application that summarizes long articles and generates headlines. They want to use Gemini models with enterprise controls and need to understand which capabilities are provided by Vertex AI. (Choose two.)

Accepted Answer

Access to Gemini models through a managed API with enterprise security and data governance controls.. Vertex AI delivers managed access to Gemini with enterprise security and governance, plus tuning and evaluation tools to align models with custom summarization criteria. These two capabilities directly support a production media application that needs controlled model access and measurable quality. The remaining options describe publishing outcomes or unrealistic automation that Vertex AI does not provide.

Answer

Automated generation of print-ready magazine layouts from article text.

Answer

Guaranteed placement of generated headlines on the publication's homepage.

Answer

Automatic translation of every generated article into all supported languages without configuration.

Question 7

A university wants to deploy a generative AI study assistant across six faculties. Each faculty has its own curriculum documents and privacy rules, and the central IT team must prevent one faculty's content from appearing in another faculty's answers. Which architecture decision best satisfies this governance requirement?

Accepted Answer

Create a separate grounded data store and retrieval configuration per faculty, and route each request only to its own faculty's store.. Separating grounded data stores per faculty enforces isolation at the retrieval layer, so answers can only draw on the requesting faculty's curriculum regardless of prompt wording. Each faculty keeps control of its own privacy rules, while central IT operates a single assistant platform. This structural separation is the only option that prevents leakage by design rather than by model compliance.

Answer

Fine-tune the model separately on each faculty's curriculum and expose a single endpoint that selects the adapter at random.

Answer

Deploy the assistant in a single project with one service account and apply IAM conditions based on the user's email domain.

Answer

Use one shared data store for all curricula and rely on prompt instructions telling the model to answer only from the requesting faculty's material.

Question 8

A company is using Google Cloud's generative AI offerings to build a customer-facing application. They need to ensure that the AI-generated content complies with their brand guidelines and does not produce harmful or inappropriate responses. They also want to monitor and filter content in real-time. Which Google Cloud feature should they use?

Accepted Answer

Vertex AI safety filters and attributes. Vertex AI safety filters and attributes are the correct choice because they are specifically designed to detect and block harmful content in generative AI outputs. They can be configured to enforce brand-specific guidelines and are applied in real-time during model inference. The other options are security or data protection services that do not address content moderation for generative AI.

Answer

Cloud Armor

Answer

Identity and Access Management (IAM)

Answer

Cloud Data Loss Prevention (DLP)

Question 9

A financial analytics firm is building a generative AI application that must analyze long earnings call transcripts and produce summaries. The transcripts often exceed 200,000 tokens, and the firm wants to minimize cost while maintaining high accuracy. They plan to use Gemini models on Vertex AI. Which approach should they take?

Accepted Answer

Use gemini-1.5-pro with its long context window and pass the entire transcript in a single request.. Gemini 1.5 Pro's extended context window allows the entire transcript to be processed in one request, preserving cross-references and reducing the need for complex chunking pipelines. Chunking loses context, gemini-1.0-pro lacks the required context length, and fine-tuning does not increase context capacity, so the long-context model is the most accurate and cost-effective choice.

Answer

Use gemini-1.0-pro and rely on its built-in automatic long-document summarization feature.

Answer

Split the transcript into 1,000-token chunks and summarize each chunk separately, then concatenate the summaries.

Answer

Fine-tune a smaller Gemini model on the firm's past transcripts and use it for summarization.

Question 10

A software vendor is building a product that must call a Gemini model through a stable, versioned API with enterprise controls such as VPC Service Controls, and must run on Google Cloud infrastructure. Which Google Cloud offering should the vendor use?

Accepted Answer

The Gemini API in Vertex AI. The Gemini API in Vertex AI is the enterprise path to Google's foundation models: it offers versioned endpoints, runs on Google Cloud, and integrates with IAM, VPC Service Controls, and audit logging. Workspace is an end-user assistant, AI Studio targets prototyping without enterprise governance, and Feature Store serves ML features rather than generative model inference.

Answer

Gemini for Google Workspace

Answer

Google AI Studio

Answer

Vertex AI Feature Store

Question 11

A marketing team uses a generative AI model on Vertex AI to create ad copy variations. The outputs are often too random and include off-brand phrases. They want to reduce randomness while still allowing some creativity. Which parameter should they adjust?

Accepted Answer

Temperature. Temperature is the primary parameter that scales the randomness of token selection. Lowering temperature makes the model more likely to choose high-probability tokens, resulting in more predictable and brand-safe output. While top-K and top-P also influence diversity, they are secondary to temperature for controlling overall randomness.

Answer

Top-P

Answer

Top-K

Answer

Max output tokens

Question 12

Question 13

A small marketing agency wants to add an AI assistant that summarizes campaign briefs and drafts social posts. The developers have limited cloud experience and prefer a fully managed, serverless way to call Google's Gemini models without provisioning infrastructure. Which approach best meets this requirement?

Accepted Answer

Use the Gemini API through Google AI Studio for rapid prototyping and API-key access. When the goal is simply to consume Gemini capabilities with minimal setup, the managed Gemini API accessed through Google AI Studio removes infrastructure concerns entirely. It supports summarization and drafting through straightforward API calls, letting a small team focus on prompts and application logic rather than serving stacks. Self-hosted or custom-trained alternatives introduce operational or data-science overhead the scenario does not require.

Answer

Build a Cloud Run service that hosts a self-managed transformer container

Question 14

An e-commerce company wants to add a conversational shopping assistant to its mobile app. The assistant must answer product questions using the company's catalog, call a backend API to check live inventory, and escalate to a human agent when the customer requests it. Which Google Cloud offering is designed for this?

Accepted Answer

Vertex AI Agent Builder. Vertex AI Agent Builder provides the components to build conversational agents with grounding in enterprise data, function calling for backend APIs, and escalation paths to human agents. It directly supports catalog-grounded answers, live inventory checks, and handoff, matching the scenario. The other services are model catalogs, batch pipelines, or productivity tools that do not deliver agent orchestration for a mobile assistant.

Question 15

A bank is building a Gemini-powered assistant on Vertex AI that must answer questions about internal policy documents and must not fabricate policy details. The architects want to reduce hallucination and provide auditable sourcing. Which two Google Cloud capabilities should they combine? (Choose two.)

Accepted Answer

Enabling citations that map generated statements to retrieved source chunks. Grounding retrieves authoritative passages so responses are conditioned on real policy text, and citations expose exactly which passages supported each statement. Together they reduce fabrication and create an auditable chain from answer to source. Generation settings and safety controls do not supply factual anchoring, and fine-tuning on unrelated marketing material cannot substitute for retrieval over the actual policy corpus.

Answer

Fine-tuning the model on the bank's public marketing brochures

Answer

Disabling safety filters to allow unrestricted policy answers

Answer

Setting the model temperature to its maximum value

Question 16

A logistics company must answer employee questions using its internal policy manuals, which change weekly. The manuals are stored in a Cloud Storage bucket and must never be used to train a shared model. The company wants relevant, up-to-date answers with citations. Which Google Cloud approach should it use?

Accepted Answer

Use Vertex AI Search with the Cloud Storage bucket as a grounded data store. Grounding responses in a Vertex AI Search data store keeps answers tied to the current contents of the Cloud Storage bucket and provides citations to the source passages. Because the documents are indexed rather than used to train a shared model, the company retains control over sensitive policy text. Fine-tuning and prompt stuffing both fail on freshness, data handling, or scalability.

Answer

Fine-tune a Gemini model on the policy manuals and redeploy it weekly

Answer

Export the manuals into prompt text and paste them into every request

Answer

Increase the Gemini model's temperature setting to improve factual recall

Question 17

A logistics company wants its internal assistant to answer questions using its private fleet maintenance manuals. The manuals change weekly, and the company does not want to retrain a model each time. Accuracy must be traceable to the source document. Which Google Cloud approach should they implement?

Accepted Answer

Use Retrieval-Augmented Generation with Vertex AI Search as the grounding data store. Retrieval-Augmented Generation keeps the knowledge in an external index rather than in model weights. Vertex AI Search can index the private manuals, refresh them as they change, retrieve relevant passages per query, and return grounding metadata that supports citations. Fine-tuning, temperature changes, and static system instructions either require retraining, do not retrieve private data, or cannot scale to frequently updated documents.

Answer

Distill the manuals into a system instruction embedded in every prompt

Answer

Fine-tune a Gemini model on the maintenance manuals using supervised tuning

Answer

Increase the model temperature so it produces more detailed answers

Question 18

A media company is building an application that must summarize 400-page legal contracts. Their current model has a context window of only 32,000 tokens, and truncating the documents loses critical clauses. They want to use a Gemini model on Vertex AI that can ingest the entire contract in a single request. Which Gemini model capability should they select for this workload?

Accepted Answer

A Gemini model variant with a 1 million token context window. The blocker is input capacity: a 400-page contract far exceeds 32,000 tokens. Gemini 1.5 Pro and Gemini 1.5 Flash on Vertex AI offer context windows up to 1 million tokens, letting the application pass the full document plus instructions in one call. Output limits, grounding, and fine-tuning change generation length, factual grounding, or behavior respectively, but none of them enlarges the input window.

Answer

A Gemini model fine-tuned on legal contracts with supervised tuning

Answer

A Gemini model variant with a 32,000 token context window plus a larger output token limit

Answer

A Gemini model with grounding enabled through Vertex AI Search

Question 19

A marketing team wants to generate personalized email subject lines that match their brand voice. They need a Google Cloud service that allows them to fine-tune a generative model on their own email data. Which service should they use?

Accepted Answer

Vertex AI. Vertex AI is the Google Cloud platform that supports fine-tuning generative models like Gemini on custom datasets. It allows the marketing team to train a model on their email data to capture their brand voice and generate personalized subject lines. Other services either lack generative capabilities or are not intended for fine-tuning on custom text data.

Question 20

A media company wants its editorial team to summarize long internal reports and ask follow-up questions about the content, all inside a Google Workspace interface they already use daily. They prefer not to build any custom application or call APIs. Which Google Cloud generative AI offering should they adopt?

Accepted Answer

Gemini for Google Workspace. Gemini for Google Workspace is the offering designed to bring Gemini capabilities directly into the productivity apps an organization already uses, including document summarization and conversational assistance. Because the team wants those abilities inside Docs and Gmail without developing a custom application, the embedded Workspace assistant fits, whereas developer consoles and narrow pretrained APIs do not match the consumption model or the feature set requested.
