質問 # 38
A context engineer is building a customer support agent on Databricks. The agent's session-initialization routine must populate a context object before turn 1 begins; the context object is then passed to every turn handler. The agent needs the user's plan tier, region, and a few entitlement flags from the Lakebase customer_profile table in that context object. The values must be present before the first turn handler executes and may be referenced on any subsequent turn. The values do not change during a session, but could change across different sessions. The team wants to minimize per-turn Lakebase round-trips and the latency they add to turn responses.
Which retrieval approach should the engineer implement for this agent architecture?
正解：D
解説：
Preloading customer profile information into the session context provides the required balance between data availability, consistency, and retrieval efficiency.
The scenario establishes three important constraints: profile attributes must be available before the first interaction, their values remain unchanged during a session, and those values may change between sessions.
Option B meets these requirements by retrieving the relevant records from Lakebase during session initialization.
The agent stores the plan tier, region, and entitlement flags in a session-scoped context object. Because the object is available to every turn handler, subsequent interactions can reuse the information without executing additional database queries.
This eliminates repeated Lakebase round-trips and reduces both latency and database workload.
Option A introduces a shared cache that may return stale values when account information changes between sessions. Option C adds unnecessary database access to individual turns. Option D introduces periodic refresh operations despite the explicit guarantee that the values do not change during an active session.
Databricks supports stateful agent architectures through session management and Lakebase-backed persistence. Session-specific context is appropriate for information needed repeatedly within a single interaction.
The implementation should retrieve the profile using the authenticated user identity, perform initialization before processing the first turn, and create a fresh context object for each new session.

質問 # 39
A context engineer is evaluating a Databricks agent deployed for a manufacturing company's field service team. The agent uses a DELTA_SYNC Databricks AI Search index to search a knowledge base of equipment troubleshooting guides. The product line includes closely related models (CX-400, CX-410, CX-420) whose guides use similar procedural language but specify different part numbers, torque values, and calibration sequences for each model. The index uses databricks-gte-large-en embeddings with a chunk_size of 512 tokens and a chunk_overlap of 50 tokens. Evaluation shows that when a technician queries for a specific model, such as "CX-400 belt tensioner replacement procedure," the agent frequently returns procedures for a different model in the same product family. The returned content appears relevant but contains incorrect part numbers and specifications for the queried model.
Which Databricks AI Search configuration change directly addresses this retrieval pattern?
正解：C
解説：
The retrieval failure results from excessive reliance on semantic similarity when documents contain nearly identical terminology but differ in critical identifiers.
The CX-400, CX-410, and CX-420 service manuals may describe the same general maintenance operations.
Consequently, their embedding vectors can occupy nearby positions in vector space despite containing different specifications and procedures.
Approximate nearest-neighbor retrieval may therefore return passages that are semantically relevant but factually inappropriate for the requested equipment model.
Databricks AI Search supports hybrid retrieval through the query_type= " HYBRID " setting.
Hybrid search combines approximate nearest-neighbor semantic retrieval with full-text keyword retrieval. The results are merged using Reciprocal Rank Fusion, allowing both conceptual similarity and exact terminology to influence ranking.
This is particularly effective when queries contain product identifiers, model numbers, technical codes, or other distinguishing terms.
Option B changes the embedding representation without explicitly addressing exact-token matching. Option C reduces chunk size but may remove necessary procedural context. Option D can improve relevance ordering, but reranking alone may not recover a correctly identified document absent from the initial candidate set.
For safety-critical maintenance procedures, hybrid retrieval should ideally be supplemented by model-specific metadata filtering and evaluation against known correct procedures.

質問 # 40
A context engineer is reviewing an agent built on Databricks that helps warehouse operations staff with inventory queries. The agent is configured with a system prompt (120 tokens), a conversation history window (400 tokens), 10 tool definitions averaging 180 tokens each (1,800 tokens total), and a RAG pipeline that retrieves a 1,600-token document chunk at runtime. The total context regularly exceeds the model's 4,096- token limit, causing conversation history to be truncated and degrading multi-turn coherence. Usage logs show low session variety, repetitive task patterns, and an average of 3-4 tools invoked per session.
Which change to the agent configuration will most effectively reduce the token budget and improve model focus?
正解：D
解説：
Dynamic tool routing is the most effective strategy because the application exposes considerably more tool definitions than are typically required for an individual request.
The configured system prompt, history, tool definitions, and retrieved document consume approximately
3,920 tokens before accounting for the current user message and response allowance.
This leaves only 176 tokens within the model ' s 4,096-token context limit.
Of the configured components, tool definitions account for 1,800 tokens, representing a substantial opportunity for optimization.
Option D introduces an intent-aware routing mechanism that dynamically selects relevant tools for each request.
If four tools are required, the tool-definition footprint falls from approximately 1,800 tokens to 720 tokens, saving 1,080 tokens. Selecting three tools would reduce the footprint to approximately 540 tokens.
Unlike a static tool shortlist, dynamic routing preserves access to less frequently used capabilities when genuinely required.
Option A reduces retrieved content but does not address unnecessary tool exposure. Option B sacrifices conversational continuity. Option C permanently excludes less frequently used tools, potentially preventing valid workflows.
Databricks supports agent tool discovery, MCP integration, and governed tool access. These capabilities can support selective tool exposure within a custom routing implementation.
The engineer should evaluate routing accuracy alongside token consumption to ensure that optimization does not prevent the agent from selecting essential tools.

質問 # 41
A context engineer is creating a Databricks agent to triage incoming customer support tickets for a B2B software platform. Each ticket averages 200 tokens.
For each ticket, the agent must:
(1) assign a severity rating of P0/P1/P2/P3 based on whether the issue is fully blocking, degrades core functionality, affects a non-critical feature, or is informational-a judgment that requires reading the ticket body rather than matching keywords; (2) route the ticket to one of eight engineering teams based on the technical area implied by the ticket; (3) generate a brief, context-aware acknowledgment reply.
The pipeline must process up to 500 tickets per minute with an end-to-end latency budget of under 2 seconds per ticket. The token budget per invocation is 2,048 tokens, and the operations team has flagged that inference costs must remain minimal at this throughput.
Which reasoning mode should the context engineer configure for the agent?
正解：C
解説：
Reduced thinking is the most appropriate configuration because the workload requires limited semantic reasoning while operating under stringent throughput, latency, and inference-cost constraints.
The agent must interpret ticket descriptions, distinguish severity levels, identify the responsible engineering team, and generate an acknowledgment. These operations require contextual understanding, but they do not ordinarily warrant extensive multi-step deliberation.
Databricks Foundation Model APIs support model-dependent controls for reasoning effort. Lower reasoning effort generally reduces reasoning-token consumption and can improve response latency, while higher effort may benefit more complex analytical workloads.
Option A prioritizes minimum inference overhead but assumes reasoning can be eliminated without compromising classification accuracy. That assumption is not justified by the scenario. Options B and C introduce extended reasoning overhead that is difficult to justify for short, repetitive triage requests.
Option D provides a more suitable balance between classification accuracy and execution efficiency.
In production, the engineer should benchmark low-effort reasoning against labeled tickets, monitor severity- classification accuracy, routing accuracy, acknowledgment quality, p95 latency, and token usage, and verify that the system meets its throughput requirements.
The exact configuration parameter depends on the selected serving model; reduced thinking is a conceptual choice rather than a universally named Databricks API mode.

質問 # 42
A context engineer is building a multi-agent Databricks workflow where an orchestrating agent coordinates five sub-agents, each performing document analysis, entity extraction, and summarization tasks. The orchestrator receives the complete raw output from each sub-agent, including intermediate reasoning chains, extracted entity lists, and status messages, and appends all of it to its running context window before issuing follow-up instructions. After scaling to production document volumes, the orchestrator's context window consistently saturates before all sub-agent results are processed, causing truncation errors and a loss of task coherence.
Which two changes to sub-agent output design would reduce the orchestrator's context load while preserving the information it needs to continue coordinating tasks?
Choose two
正解：C、D
解説：
The orchestrator is suffering from context saturation because sub-agents return excessive intermediate information rather than concise, actionable results.
Option A introduces structured output contracts that restrict each sub-agent ' s response to essential coordination information. These records should include execution status, extracted entities, confidence scores, and relevant task identifiers.
Removing verbose intermediate reasoning and redundant status messages substantially reduces the context consumed by each agent response.
Option E complements this approach by moving complete sub-agent outputs into persistent storage backed by Lakebase. Instead of transferring large documents and intermediate results through the orchestrator ' s prompt, sub-agents can return identifiers referencing their stored outputs.
A practical implementation combines both approaches: the orchestrator receives a concise structured summary and a reference to the complete underlying result.
When additional evidence is required, the orchestrator can retrieve the relevant stored information selectively.
Databricks supports multi-agent orchestration and Lakebase-backed persistent agent state. These capabilities enable application-specific designs that separate active context from durable execution artifacts.
Option B reduces available specialization, while Option C merely increases capacity without resolving inefficient information transfer. Option D abandons the existing multi-agent architecture and may recreate the original context-saturation problem.
The selected design improves scalability while maintaining access to detailed results and supporting evidence.
