Question 1:
A bank already reviewed top-line fairness summary metrics for a credit-risk model, but the approval board wants two additional checks before sign-off. They specifically want to identify which customer segments experience materially different failure patterns and understand which input features are driving model behavior.
Which TWO actions best address that requirement? (Select TWO.)
A.Review endpoint latency and throughput metrics
B.Run counterfactual what-if analysis first
C.Use error analysis across cohorts
D.Review feature importance explanations
E.Inspect model registry lineage
Answer: C and D
Explanation:
The requirement is not just to view overall fairness summaries but to understand subgroup failure patterns and the drivers of model behavior. In the Responsible AI dashboard, error analysis helps identify where the model performs poorly across slices or cohorts, while feature importance provides model explanations about which inputs are influencing predictions. Together, those two capabilities directly answer the board’s request.
Microsoft describes the Responsible AI dashboard as a single interface that brings together mature tools such as error analysis, model overview and fairness metrics, data analysis, feature importance, counterfactual what-if, and causal analysis. Because the scenario says the fairness summary is already reviewed, the next two most relevant tools are the ones that diagnose subgroup failures and explain feature influence.
Incorrect:
A. Endpoint latency and throughput are operational observability measures, not responsible AI evaluation techniques for model behavior. They help monitor serving performance, not subgroup error patterns or interpretability. This option confuses runtime monitoring with model assessment.
B. Counterfactual what-if analysis is a valid Responsible AI capability, but it is not the most direct pair for the stated need. The board wants to find materially different failure patterns across segments and understand feature drivers. Error analysis and feature importance map more directly to those two asks than counterfactual exploration does.
E. Model registry lineage is useful for traceability and governance, but it does not evaluate whether the model behaves differently across cohorts or explain which features drive outcomes. It addresses provenance, not responsible AI assessment of prediction behavior.
Question 2:
A support agent built in Microsoft Foundry must block medium-and-above violent or self-harm completions, but the team does not want to block low-severity user prompts that are still legitimate support requests. They also want jailbreak detection enabled and need the policy applied only to the production deployment that serves external customers.
Which action is the best fit?
A.Connect Application Insights and enable tracing
B.Create a custom content filter and associate it with the deployment
C.Raise the model temperature and shorten responses
D.Restrict public network access and tighten RBAC
Answer: B
Explanation:
Microsoft Foundry content filtering is designed for exactly this scenario. Microsoft documents that custom content filters can be created in Foundry, configured separately for input and output, and then associated with one or more deployments. Foundry also supports optional binary classifiers such as jailbreak risk, which makes a custom content filter the most direct way to enforce output safety policies without overblocking acceptable prompt traffic.
This is stronger than trying to solve the problem through model behavior tuning or infrastructure controls. The requirement is policy-based moderation on generated outputs, with separate handling for prompts and completions, plus deployment-scoped enforcement. That lines up with Foundrys built-in content filtering workflow rather than observability, networking, or generation-style tuning.
Why the other options are incorrect:
A. Connecting Application Insights and enabling tracing helps with observability and debugging, not with blocking harmful completions before they reach users. Tracing can show prompt content, retrieval operations, latency, exceptions, and span-level execution details, but it does not replace guardrail enforcement. The scenario needs runtime safety policy enforcement on inputs and outputs, which is a content-filtering responsibility.
C. Raising temperature and shortening responses changes generation behavior, but it does not implement a defined safety policy. Harm categories and severity thresholds are handled by Foundry’s content filtering system, not by stylistic generation controls. This option also fails the requirement to detect jailbreak attempts and scope the policy to a specific deployment.
D. Network restrictions and RBAC are important governance controls, but they address access and isolation rather than harmful output moderation. They do nothing to classify violent, self-harm, hate, or sexual content in prompts or completions. The problem is not who can reach the service, but how generated content is screened and blocked.
Question 3:
A customer support copilot has doubled in cost over the past week, but the team confirms that request volume and deployment count have stayed flat. They want the metric pattern that most strongly points to the real cause before they switch models or redesign prompts.
Which pattern is the best indicator of the cost driver?
A. Stable tokens but lower success rate
B. Rising 5xx errors and retry traffic
C. Higher throughput with fewer prompt tokens
D. Higher completion tokens per call
Answer: D
Explanation:
When traffic volume is flat but costs rise, the most direct explanation is often more tokens consumed per interaction. Microsoft Foundry monitoring guidance calls out token consumption as a first-class monitoring signal, and the Foundry dashboard documentation explicitly highlights prompt and completion token tracking for cost analysis. If completion tokens per request climb materially, costs can rise even when traffic and deployment footprint stay unchanged.
This also points to the right optimization path. Once the team confirms that output-token growth is the main driver, it can investigate prompt design, output constraints, model choice, or other cost-efficiency changes. But the first step is identifying the right metric signal, and completion-token growth is the clearest match to the scenario.
Why the other options are incorrect:
A. Lower success rate can be an important reliability problem, but it is not the strongest explanation for a cost spike when request volume is flat. In many cases, a falling success rate would reduce completed output generation rather than directly double token spend. The scenario is asking for the cost driver, not just any unhealthy signal.
B. Error rates and retries can increase cost, but the option is weaker than direct evidence of increased completion-token usage. If retries were the main cause, the team would usually see a corresponding traffic-pattern anomaly rather than a pure per-call token expansion signal. This choice is plausible, but it is not the best fit given the wording of the scenario.
C. Higher throughput with fewer prompt tokens points in the opposite direction of the stated problem. That pattern would more often suggest improved efficiency or at least a need to inspect total request volume, which the scenario already says is flat. It does not explain why cost rose while the number of requests stayed steady.
Question 4:
A team is deploying a public-facing writing assistant and wants its validation pipeline to identify harmful prompts before generation and detect unsafe generated text during evaluation. The security lead does not want the team to rely only on prompt wording or manual spot checks.
Which TWO controls best fit this requirement? (Select TWO.)
A. Fluency evaluator for all prompts and outputs
B. Azure AI Content Safety for harmful content detection
C. Relevance evaluator with stricter thresholding
D. Safety system message only, with no separate safety service
E. Prompt Shields to analyze adversarial or jailbreak-style prompts before generation
Answer: B and E
Explanation:
Microsoft describes Azure AI Content Safety as a service for detecting harmful user-generated and AI-generated content. It also describes Prompt Shields as a unified API in Azure AI Content Safety that detects and blocks adversarial user input attacks on LLMs before content is generated. Together, those controls align well with a pipeline that needs both harmful-content screening and pre-generation defense against unsafe or jailbreak-style prompts.
That makes B and E the correct pair. One addresses broader harmful-content detection, and the other specifically targets adversarial prompt attacks. This is stronger than relying on prompt instructions alone, because Microsoft explicitly distinguishes safety system messages from the Azure AI Content Safety service.
Why the other options are incorrect:
A. Fluency is a language-quality metric, not a harmful-content detector. A fluent answer can still be unsafe, abusive, or policy-violating. Microsoft treats fluency as part of general response quality, not risk and safety evaluation.
C. Relevance measures how well a response addresses the query, not whether the content is harmful. Tightening a relevance threshold might filter off-topic answers, but it does not replace safety screening for hate, violence, self-harm, or adversarial prompts. This option confuses quality measurement with safety control.
D. Microsoft states that safety system messages are only one of many mitigation techniques and are different from the Azure AI Content Safety service. They are useful, but the question explicitly rejects relying only on prompt wording. A system message alone is therefore not the strongest operational answer.
Question 5:
A RAG assistant indexes long policy PDFs as very large chunks, and users report that the system often misses the one paragraph that actually contains the answer. The current vector query also applies a strict minimum threshold, so borderline-but-useful passages are often filtered out.
Which TWO changes are the best first tuning actions? (Select TWO.)
A. Increase chunk size to several pages
B. Reduce chunk size to semantically coherent sections
C. Lower the minimum similarity threshold slightly
D. Use structure-aware chunking during indexing
E. Disable vector search and rely on filters
Answer: C and D
Explanation:
Structure-aware chunking is a high-value first fix because Microsoft’s Azure AI Search guidance explains that chunk quality and semantic coherence materially affect relevance in RAG systems. Separately, Azure AI Search RAG guidance highlights minimum thresholds as a relevance-tuning lever, so relaxing an overly strict threshold can recover useful candidate passages that were being filtered out too aggressively. Together, those changes directly address both the oversized-chunk problem and the low-recall threshold problem described in the scenario.
This is why these two actions are stronger than simply making chunks even larger or removing vector retrieval entirely. Microsoft’s guidance for RAG in Azure AI Search emphasizes chunking, hybrid query patterns, semantic ranking, and relevance-tuning controls such as vector weighting and thresholds because retrieval quality depends on how content is segmented and admitted into the candidate set.
Why the other options are incorrect:
A. Increasing chunk size to several pages usually makes the problem worse, not better. Microsoft’s chunking guidance emphasizes semantically coherent, independently retrievable chunks rather than oversized segments that bury the relevant passage inside too much surrounding text. Large chunks can weaken retrieval precision and reduce answer grounding quality.
B. Reducing chunk size to semantically coherent sections is directionally correct, but it is not the best pair with itself because the question asks for exactly two changes and the stronger second action is threshold tuning under the scenario’s explicit threshold problem. Option D is more specific and more directly aligned to Microsoft’s documented structure-aware chunking guidance. Option B is plausible, but D is the more precise operational action.
E. Disabling vector search and relying on filters would remove the semantic retrieval capability that RAG systems use to surface conceptually relevant passages. Microsoft’s RAG guidance instead recommends improving relevance with chunking, thresholds, vector tuning, hybrid queries, and semantic ranking. This option throws away a core retrieval strength rather than tuning it.

Question 6:
A team is building a compliance assistant in Foundry and wants the model to answer only within policy scope, return a fixed JSON schema, and explicitly say when the supplied information is insufficient. They also want the behavior to remain consistent across repeated tests before they start broader evaluation runs.
Which prompt design change should they make first?
A. Add a system message that defines role, scope, output contract, and a when-unsure rule
B. Increase temperature and top-p together to surface more policy interpretations
C. Move the policy text into the user message and remove higher-priority instructions
D. Replace the prompt with a batch scoring dataset and let the evaluator infer the schema
Answer: A
Explanation:
Microsoft’s system message guidance for Azure OpenAI says system messages are used to define the assistant’s role and boundaries, set tone, specify output formats such as JSON, and add safety and quality constraints. The same guidance also recommends adding a “when unsure” policy for ambiguous, out-of-scope, or underinformed cases.
That makes a well-structured system message the best first move here. It directly addresses the team’s need for scope control, consistent output structure, and graceful handling of missing information before they begin larger evaluation and iteration cycles. Microsoft also warns that prompt behavior must be tested and iterated because system messages can fail in edge cases, which fits the scenario’s emphasis on consistency before wider rollout.
Why the other options are incorrect:
B. Raising temperature and top-p generally increases variability, which works against the requirement for stable policy-constrained behavior. The team wants consistency and predictable adherence to role and format, not more diverse completions. The primary issue is instruction design, not creativity tuning.
C. Microsoft describes the system message as the highest-level instruction layer for chat behavior, so moving critical constraints out of it weakens control rather than strengthening it. That would make scope, format, and refusal behavior less reliable in multi-turn use. The scenario requires stronger instruction hierarchy, not a weaker one.
D. Evaluation is important later, but an evaluator does not replace prompt design. The team first needs a prompt that clearly states role, boundaries, and output expectations before it makes sense to score that behavior. Evaluation measures quality; it does not author the operational prompt contract for the model.
Question 7:
A pharmaceutical knowledge assistant uses a general embedding model, but retrieval quality is poor for drug names, formulation abbreviations, and highly specialized clinical terminology. The team confirms that this vocabulary is strongly domain-specific and that no approved domain embedding model is currently available for deployment.
Which approach is the best fit?
A. Fine-tune a general embedding model
B. Use keyword search as the only retriever
C. Enable semantic captions and answers only
D. Increase the chat model token limit
Answer: A
Explanation:
Microsoft’s RAG architecture guidance says embedding-model choice significantly affects vector-search relevance and recommends choosing based on vocabulary overlap with the target data. It further shows that when the content is domain-specific and no domain model is available, the next best path is to fine-tune a general model. That makes fine-tuning the best-fit action here.
This is more targeted than changing answer formatting or abandoning semantic retrieval. The retrieval problem originates in the embedding space, where specialized vocabulary is not being represented well enough for similarity search. Improving the embedding model is therefore the most direct way to improve domain-specific retrieval accuracy.
Incorrect:
B. Keyword-only retrieval may recover some exact matches, but it abandons the semantic retrieval benefits that embeddings provide. The problem described is not that retrieval should stop using vectors; it is that the current embedding model does not represent the specialized vocabulary well enough. Microsoft’s guidance points to better embedding selection or fine-tuning, not retreating to keyword-only search.
C. Semantic captions and answers are downstream search features that can improve presentation and some aspects of ranking, but they do not fix a weak embedding space for domain vocabulary. The core issue here is poor vector relevance caused by terminology mismatch. This option treats symptoms around result presentation rather than improving the representation used for retrieval.
D. Increasing the chat model token limit affects generation length, not how the search system encodes or retrieves specialized content. It would not improve similarity matching for drug names or domain abbreviations. The retrieval failure occurs before answer generation.
Question 8:
A legal-tech team needs to adapt a foundation model to highly specialized contract language. They have a limited tuning budget, want faster iteration across multiple experiments, and do not want to retrain the full base model for every revision.
Which approach is the best fit?
A. Full retraining on a larger base
B. Parameter-efficient fine-tuning
C. Prompt-only versioning
D. Batch endpoint shadow testing
Answer: B
Explanation:
Parameter-efficient fine-tuning is the best fit because it is designed for domain adaptation when teams want lower cost and faster iteration than full-model retraining. It lets the team customize model behavior for specialized legal language while keeping the tuning process more operationally manageable. That matches the stated constraints better than a heavyweight retraining strategy.
Prompt-only versioning can help with behavior shaping, but it is not the same as fine-tuning and may not be sufficient for deep domain adaptation. Batch endpoint shadow testing is a deployment validation pattern rather than a tuning method. Full retraining is the most expensive and operationally heavy option here, which directly conflicts with the budget and iteration constraints.
Incorrect:
A. Full retraining on a larger base is far heavier than the scenario requires. It increases cost, infrastructure demands, and iteration time, which makes it a poor match when the team explicitly wants faster experimentation. It also introduces more operational burden than necessary for a customization problem. The question is about the best fine-tuning method under constraints, not the biggest possible training strategy.
C. Prompt-only versioning is useful for experimentation and orchestration, but it does not implement advanced fine-tuning. If the team needs the model itself to adapt more deeply to specialized contract patterns, prompts alone may not provide durable enough behavior change. It also leaves the model weights untouched, which is a key limitation in this scenario. This is a lighter customization technique, not the best fit method.
D. Batch endpoint shadow testing is about evaluation in a deployment workflow, not about creating the customized model itself. It can be valuable later in the lifecycle, but it does not answer how to perform the fine-tuning. Choosing it would confuse deployment validation with model adaptation. The scenario is asking for the tuning approach, not the production test pattern.
Question 9:
An insurer must score 4 million claim records every night and deliver results before 4:00 AM. The workload is not interactive, requests arrive as large files rather than per-user API calls, and the operations team wants a managed Azure Machine Learning inference pattern rather than custom orchestration.
Which deployment choice is the best fit?
A. Managed online endpoint with one deployment
B. Serverless API endpoint for nightly scoring
C. Batch endpoint with managed compute
D. AKS online endpoint with custom ingress rules
Answer: C
Explanation:
A batch endpoint with managed compute is the best fit because the scoring pattern is scheduled, file-based, and non-interactive. The requirement is high-throughput offline inference within a time window, not low-latency request-response serving. Batch endpoints are designed for exactly this kind of production scoring workload.
The other choices all introduce unnecessary real-time serving semantics or extra infrastructure overhead. A managed online endpoint is optimized for request-driven inference, while an AKS-based option adds operational complexity that the scenario does not require. The best decision is the one that matches workload shape, operational model, and managed-service intent together.
Incorrect:
A. A managed online endpoint is intended for request-response inference where clients need fast answers per invocation. That does not match a nightly bulk scoring job over millions of records. It would force the team into an operational pattern centered on API traffic instead of file-oriented batch execution. Even though it is managed, it is still the wrong serving model for this workload.
B. A serverless API endpoint still represents an online inference pattern. The workload described is not event-driven interactive traffic but large-scale scheduled scoring, so serverless API semantics do not solve the core job design. It can also make throughput planning and input partitioning less natural than a batch construct. The question is about workload fit, not just avoiding infrastructure management.
D. An AKS online endpoint with custom ingress rules adds cluster-level and networking complexity without a stated requirement for that control plane. The scenario explicitly prefers managed inference options, which makes a Kubernetes-heavy answer less attractive. It also keeps the team in an online serving model for a fundamentally offline workload. That is design drift, not best fit.
Question 10:
A team stores training files in Azure Data Lake Storage Gen2 and wants multiple Azure Machine Learning jobs to reference that storage without hardcoding long URIs into every job definition. The security team also wants connection handling centralized so the platform can use supported authentication patterns instead of embedding secrets in scripts.
What should the team create first?
A. A versioned data asset
B. A compute cluster
C. An environment
D. A datastore
Answer: D
Explanation:
A datastore is the Azure Machine Learning resource used to connect an existing Azure storage service to the workspace. Microsoft documentation is explicit that datastores do not create the underlying storage account; they link existing storage for machine learning use. That makes a datastore the correct first construct when the requirement is centralized workspace access to storage without repeating raw storage paths in every job.
A data asset can absolutely be layered on top afterward for versioning, lineage, reproducibility, and friendly named references. But that is a different concern from establishing the workspace storage connection itself. In this scenario, the team first needs the storage connection abstraction, so datastore is the right answer and the most natural starting point.
Incorrect:
A. A data asset is useful when you want versioning, reproducibility, lineage, and a named reference to specific data. Microsoft even notes that data assets behave like friendly bookmarks to data paths. But a data asset is not the primary construct for linking the workspace to the storage service in the first place, so it is not the best first step here.
B. A compute cluster is a managed compute target for running jobs, especially scalable training workloads. It does not solve the workspace storage-link problem or provide the connection abstraction the scenario is asking for. Choosing compute first confuses execution infrastructure with data connection management.
C. An environment defines packages, Docker settings, and runtime dependencies for training or inference. It is about software reproducibility, not storage connectivity. Selecting an environment here would mix up runtime configuration with data access architecture.
