Sample questions

Prefer a smaller suitable model for lower response latency: Which approach is most appropriate?

1. Add retrieval so every response performs an additional document lookup.

   Retrieval can improve grounding, but unnecessary lookups may add latency when the team has no document requirement.
2. Use an agent that plans several tool calls before answering each request.

   Planning and tool calls can increase latency, making an agent unsuitable when fast direct responses are the priority.
3. Use a larger model for broader capability despite the latency priority.

   A larger model may add latency without providing needed value when quality is already adequate and complex reasoning is unnecessary.
4. Prefer a smaller suitable model for lower response latency. ✓

   A smaller suitable model can reduce response latency when its quality meets the interactive requirement.

Use retrieval units that balance focus and context: Which approach is best?

1. Split every sentence into a separate retrieval unit regardless of meaning.

   Overly small units can separate related ideas and remove context needed to interpret answers.
2. Use retrieval units that balance focus and context. ✓

   Effective chunking creates focused retrieval units while preserving enough surrounding information to answer questions accurately.
3. Place every manual into one retrieval unit to preserve all context.

   Very large units can reduce retrieval focus and consume available context with irrelevant material.
4. Remove surrounding context from each passage to minimize token usage.

   Removing context may reduce usefulness when meaning depends on definitions, conditions, or nearby explanations.

Use machine learning to predict discontinuation: Which approach best meets this requirement?

1. Use a rules engine with conditions defined by education specialists.

   Rules apply predefined logic and do not learn predictive relationships from historical outcomes.
2. Use deep learning to model the outcome with multiple neural-network layers.

   Deep learning can support prediction, but the requirement does not indicate that multilayer neural networks are necessary.
3. Use machine learning to predict discontinuation from historical student data. ✓

   Machine learning learns relationships from labeled historical examples and applies them to new student records.
4. Use a generative model to write personalized explanations of likely discontinuation.

   Generating explanations is different from selecting or predicting which students may discontinue.

Use a dedicated role with narrowly scoped permissions: Which approach is best?

1. Use a content filter to decide which cloud resources the workload may access.

   Content filters inspect selected inputs or outputs; they do not define identity permissions for cloud resources.
2. Store a long-lived administrator credential in the application environment.

   Long-lived administrator credentials increase exposure and violate least-privilege and credential-protection practices.
3. Use a dedicated role with narrowly scoped permissions for required resources and actions. ✓

   A dedicated, narrowly scoped role limits workload access to resources and actions required for its documented purpose.
4. Grant broad administrator access so the workload can handle future features.

   Broad administrator access exceeds current needs and increases the impact of compromised credentials or unintended actions.

Measure recall overall and across relevant subgroups: Which evaluation approach best addresses responsible per

1. Measure recall overall and across relevant subgroups, emphasizing missed-alert costs. ✓

   Recall captures detected alerts, while subgroup analysis reveals whether missed-alert performance differs across relevant populations.
2. Remove alert-related group information so evaluation cannot reveal unequal outcomes.

   Removing attributes can prevent subgroup analysis and does not eliminate proxy information or unequal performance.
3. Use balanced class counts as proof that the classifier is fair and reliable.

   Balanced counts do not prove equal performance, label quality, or acceptable consequences across subgroups.
4. Report overall accuracy only because it summarizes all classification outcomes in one number.

   Overall accuracy can hide missed alerts, especially when alert classes are imbalanced or operational costs differ.

Choose a model with a context window that fits: Which choice best addresses the requirement?

1. Fine-tune the model on contract examples to expand context

   Fine-tuning can adapt behavior or style, but does not ordinarily expand the context window.
2. Lower temperature to accept more contract text

   Temperature affects sampling variability, not the maximum context the model can process.
3. Choose a model with a context window that fits the contract ✓

   The complete contract must fit within the model’s usable context window for one-request processing.
4. Use embeddings alone instead of supplying the contract context

   Embeddings support similarity tasks but do not let a generative model process the complete contract directly.

Attention weighs relationships among sequence elements: Which concept best explains this capability?

1. Diffusion iteratively removes noise from an initially noisy representation.

   Denoising describes diffusion generation, not how transformers relate sequence elements during processing.
2. Chunking divides long documents into smaller retrieval units.

   Chunking organizes source material for retrieval but does not explain token-to-token relationships inside a model.
3. Embedding conversion grants a model access to every source document.

   Embeddings create numerical representations for comparison and do not inherently provide unrestricted document access.
4. Attention weighs relationships among sequence elements when processing the input. ✓

   Attention helps transformers consider relationships between tokens, including information located elsewhere in the sequence.

Deep learning: Which technology is most directly associated with this requirement?

1. Unsupervised clustering of travel bookings

   Clustering groups similar records but does not directly identify named landmarks in uploaded photographs.
2. Rule-based matching with fixed landmark conditions

   Fixed rules are difficult to maintain for varied photographs, viewpoints, lighting, and landmark appearances.
3. Deep learning ✓

   Deep learning uses multilayer neural networks and is commonly suited to complex image-recognition patterns.
4. Generative text completion for itinerary descriptions

   Text generation can create descriptions but does not itself provide landmark image recognition.
