A service changes the embedding dimension but its SQL vector column has a fixed old dimension
After the team applies the intended design, which observation would most directly verify that the specific requirement was met?
A fixed-dimensional vector column cannot store embeddings of an incompatible dimension without schema or model changes.
Model hosting and batch generation must align on dimensions, security boundaries and quotas.
CDC captures historical change records from the log, unlike key-only change tracking.
Operational logs can reveal sensitive source text or access tokens if not carefully configured.
A critical SQL function needs fast repeatable checks for boundary inputs after every edit
Which SQL design or implementation decision most directly addresses this requirement?
Unit tests isolate programmable behavior and catch regression before full integration deployment.
Policy-enforced reviews prevent bypassing designated security and database approvers.
A successful compiler build is necessary but not sufficient for quality or secure schema changes.
Automated schema comparisons may propose destructive changes that need explicit approval and migration planning.
A vector-index experiment changes ANN search parameters and results become faster but less relevant
Which SQL design or implementation decision most directly addresses this requirement?
Fast response alone is not sufficient; index parameters shift the speed-quality tradeoff.
Index freshness includes removal as well as addition and edits; stale documents can yield harmful answers.
Distance calculation requires aligned dimensions and semantics, and metric choice affects ordering.
Index membership can make data discoverable; search permission cannot be inferred from index design.
A service runs event-driven processing using an Azure SQL source and SQL trigger binding support
After the team applies the intended design, which observation would most directly verify that the specific requirement was met?
SQL trigger bindings react to detected table changes and require correct change tracking and idempotent handler logic.
Logic Apps orchestrate heterogeneous connectors and retries more directly than embedding cross-service calls in a SQL trigger.
Configuration separation allows consistent entities while credentials and endpoints differ securely across environments.
DAB entity mapping and permissions limit accessible objects and operations, complementing SQL grants.
A finance summary must retain numerical values exactly when an LLM generates narrative prose
After the team applies the intended design, which observation would most directly verify that the specific requirement was met?
LLMs are not authoritative for arithmetic or source-of-truth values; database computations should remain deterministic.
RAG context can be missing or ambiguous; the model must not fill unsupported gaps with invented facts.
RAG supplies relevant external context at answer time, reducing dependence on stale model memory but not guaranteeing truth.
Data minimization reduces privacy exposure, inference risk and token costs without impairing the specific answer.
An app uses session context in an RLS predicate but fails to reset the context between users
Which SQL design or implementation decision most directly addresses this requirement?
RLS predicates must receive authenticated tenant context and connection pooling can retain session state unless managed.
Centralized identity management reduces shared-secret exposure and improves attribution and revocation.
Separating audit custody from operational administrators reduces the risk of tampering and premature deletion.
A DENY generally overrides an inherited GRANT for an ordinary user; exceptional cases require explicit security review.
An AI coding tool calls several MCP tools and incident response cannot reconstruct its activity
After the team applies the intended design, which observation would most directly verify that the specific requirement was met?
Traceable AI-assisted operations support accountability while logs require access and retention controls.
Prompt injection in tool output must not grant new authority or override the application trust boundary.
Instruction files influence generation but do not guarantee compliance, so contradictions must be removed and checked.
Secrets in repository configuration can be leaked or copied; managed credentials reduce exposure and support rotation.
Compliance auditors need to ask what customer address was valid at a past point in time
Which SQL design or implementation decision most directly addresses this requirement?
System-versioned temporal tables maintain historical row versions so FOR SYSTEM_TIME queries can reconstruct earlier states.
Unicode-capable character types retain characters outside a single legacy code page and require appropriate length planning.
Nullability is a core schema invariant and should not be delegated solely to an API form.
Avoiding functions on the indexed search column can let the optimizer use an index seek.
A service team wants to expose a database operation but not allow uncontrolled dynamic SQL
After the team applies the intended design, which observation would most directly verify that the specific requirement was met?
DAB can expose approved programmable objects while caller identity and database permissions enforce access.
Application identity, API entity permissions and SQL authorization must jointly prevent overbroad access.
Pagination bounds response size and limits database work per request, while stable ordering is essential.
DAB reads configuration to expose chosen database objects as endpoints, subject to role and permission controls.
An optimizer change makes a critical query use a new plan with much higher IO
Which SQL design or implementation decision most directly addresses this requirement?
Query Store retains plan and runtime history so regressions can be tied to specific plan choices.
A deadlock is a cycle in lock dependencies, not merely long blocking; SQL chooses a victim transaction.
DMVs expose current and cumulative SQL diagnostics that help distinguish contention from capacity or query-plan issues.
SQL may abort one deadlock participant; retries can succeed but must not repeat non-idempotent side effects.
A SQL workload's throughput drops after reducing a database compute tier to save cost
Which SQL design or implementation decision most directly addresses this requirement?
Saving compute cost is not safe if CPU, IO or memory limits violate service-level objectives.
A deadlock is a cycle in lock dependencies, not merely long blocking; SQL chooses a victim transaction.
Efficient row identification can shorten lock holding; excess indexes can slow writes and require balanced tuning.
Versioned read-committed isolation reduces reader/writer blocking but changes consistency semantics and tempdb/version-store demand.
