Question 280

At Brookfield Labs, a coding agent cannot connect to an approved SQL MCP endpoint. The observed constraint is: Client config points to an outdated URL and unsupported auth. What operational condition would provide the earliest useful regression warning?

  1. Track spend, hallucinated APIs and model changes
  2. Monitor connection errors and token expiry
  3. Monitor migration impact and drift
  4. Monitor instruction drift and ignored conventions

Explanation

Correct Answer

B:

Client config points to an outdated URL and unsupported auth. Monitor connection errors and token expiry. A valid MCP client requires the actual approved endpoint, transport and authentication flow. An outdated URL or unsupported credential method prevents safe connection.

Incorrect Answers

A:

“Track spend, hallucinated APIs and model changes” addresses the github copilot model selection situation—tool options vary in token limits, privacy policy and quality. The observed failure is: Client config points to an outdated URL and unsupported auth. Monitor connection errors and token expiry. A valid MCP client requires the actual approved endpoint, transport and authentication flow. An outdated URL or unsupported credential method prevents safe connection.

C:

“Monitor migration impact and drift” concerns DDL change could destroy legacy data or break dependencies; the reported problem instead is Client config points to an outdated URL and unsupported auth. Monitor connection errors and token expiry. A valid MCP client requires the actual approved endpoint, transport and authentication flow. An outdated URL or unsupported credential method prevents safe connection.

D:

“Monitor instruction drift and ignored conventions” concerns Assistant creates inconsistent column and object names; the reported problem instead is Client config points to an outdated URL and unsupported auth. Monitor connection errors and token expiry. A valid MCP client requires the actual approved endpoint, transport and authentication flow. An outdated URL or unsupported credential method prevents safe connection.

Question 281

A database engineer at Cascade Manufacturing is investigating this case: Copilot proposes DROP COLUMN to satisfy new report requirement. The relevant finding is: DDL change could destroy legacy data or break dependencies. What initial check best narrows the technical cause without altering business data?

  1. Inspect workspace role and Copilot feature availability
  2. Review join keys, row estimates and generated SQL before execution
  3. Inspect generated DDL and dependent objects before merging
  4. Inspect AI tool data-handling policy and secrets in prompt history

Explanation

Correct Answer

C:

DDL change could destroy legacy data or break dependencies. Inspect generated DDL and dependent objects before merging. Generated DDL can drop data or break dependencies. Review the migration delta, existing data shape and rollback script before deployment.

Incorrect Answers

A:

“Inspect workspace role and Copilot feature availability” concerns Prompt context must not broaden Fabric workspace access; the reported problem instead is DDL change could destroy legacy data or break dependencies. Inspect generated DDL and dependent objects before merging. Generated DDL can drop data or break dependencies. Review the migration delta, existing data shape and rollback script before deployment.

B:

“Review join keys, row estimates and generated SQL before execution” concerns Generated SQL may produce accidental many-to-many amplification; the reported problem instead is DDL change could destroy legacy data or break dependencies.

D:

“Inspect AI tool data-handling policy and secrets in prompt history” concerns Unreviewed prompts could expose credentials; the reported problem instead is DDL change could destroy legacy data or break dependencies.
