Question 790

A central team manages production notebooks, job definitions and workspace folders. Following Review available workspace audit events for permissions and actors, the incident team needs evidence that Auditors require a record of changes to workspace permissions. Which observation supports closure?

  1. Deployment updates work only under deployer identity
  2. The group starts permitted runs but cannot mutate job settings
  3. Job reads target tables and fails queries on unrelated restricted tables
  4. The audit record identifies who changed the ACL and when

Explanation

Correct Answer

D:

The audit record identifies who changed the ACL and when is the matching outcome for the implemented control (Review available workspace audit events for permissions and actors) and the stated requirement “Auditors require a record of changes to workspace permissions.”

Incorrect Answers

A:

That observation is a valid indicator for “Production deployment automation needs to modify jobs while analysts need view-only access” when using Separate deployer service principal management rights from analyst view rights. The scenario instead tests “Auditors require a record of changes to workspace permissions”; the relevant result is The audit record identifies who changed the ACL and when.

B:

The group starts permitted runs but cannot mutate job settings would demonstrate the separate action Grant the appropriate run permission without job management rights, which addresses “A group should be able to run a production job but not edit its definition.” It does not verify the requirement “Auditors require a record of changes to workspace permissions” following Review available workspace audit events for permissions and actors.

C:

That observation is a valid indicator for “A job's service identity should read only the catalog tables it needs” when using Grant minimum UC USE and SELECT privileges on the exact required objects. The scenario instead tests “Auditors require a record of changes to workspace permissions”; the relevant result is The audit record identifies who changed the ACL and when.

Question 791

A compliance review validates masking and erasure across a streaming data flow. The change request states: New source rows containing PII must be masked before entering the shared silver table. Which implementation best satisfies that requirement?

  1. Add schema-evolution QA and governed-tag classification checks
  2. Restrict sink selection and enforce data-classification checks before publishing
  3. Use UC object grants and downstream projection to separate raw and aggregate access
  4. Apply governed masking/transformation at the silver promotion boundary

Explanation

Correct Answer

D:

The requirement concerns “New source rows containing PII must be masked before entering the shared silver table.” The selected operation, Apply governed masking/transformation at the silver promotion boundary, is the direct engineering control. Its effect can be checked by confirming: Test input PII is unreadable to unauthorized silver consumers.

Incorrect Answers

A:

The alternative Add schema-evolution QA and governed-tag classification checks has a distinct purpose—The team needs to prove masked columns remain protected after a new data column appears. It would not establish the required outcome (New source rows containing PII must be masked before entering the shared silver table); the necessary verification concerns Test input PII is unreadable to unauthorized silver consumers.

B:

The alternative Restrict sink selection and enforce data-classification checks before publishing has a distinct purpose—A streaming pipeline must not emit personal data to an external unapproved sink. It would not establish the required outcome (New source rows containing PII must be masked before entering the shared silver table); the necessary verification concerns Test input PII is unreadable to unauthorized silver consumers.

C:

This action solves a different issue: “The original raw table must remain in restricted bronze while analysts query safe gold aggregates.” Its normal signal is Analysts can query safe aggregate data but are denied direct raw-table access. Here the requested behavior is “New source rows containing PII must be masked before entering the shared silver table,” so that signal is not sufficient.

Question 792

A compliance review validates masking and erasure across a streaming data flow. After configuring Apply governed masking/transformation at the silver promotion boundary, the engineer must validate: New source rows containing PII must be masked before entering the shared silver table. What evidence is decisive?

  1. Analysts can query safe aggregate data but are denied direct raw-table access
  2. The current serving table no longer contains the erased customer
  3. Test input PII is unreadable to unauthorized silver consumers
  4. A new sensitive column receives the required mask before consumer access

Explanation

Correct Answer

C:

Test input PII is unreadable to unauthorized silver consumers directly measures whether Apply governed masking/transformation at the silver promotion boundary achieved the requirement “New source rows containing PII must be masked before entering the shared silver table.” It checks the operating result rather than just a configured resource name.

Incorrect Answers

A:

This signal belongs to the adjacent case “The original raw table must remain in restricted bronze while analysts query safe gold aggregates,” whose remedy is Use UC object grants and downstream projection to separate raw and aggregate access. The observed result for the present requirement is Test input PII is unreadable to unauthorized silver consumers.

B:

The current serving table no longer contains the erased customer would demonstrate the separate action Apply ordered CDC deletion handling to the curated target and downstream purge policy, which addresses “A deletion event arrives after a customer's record was previously emitted.” It does not verify the requirement “New source rows containing PII must be masked before entering the shared silver table” following Apply governed masking/transformation at the silver promotion boundary.

D:

A new sensitive column receives the required mask before consumer access pertains to a different control (Add schema-evolution QA and governed-tag classification checks) and a different need (The team needs to prove masked columns remain protected after a new data column appears). It cannot establish that Apply governed masking/transformation at the silver promotion boundary met the stated goal.

Question 793

A compliance review validates masking and erasure across a streaming data flow. The current design is incomplete because: A streaming pipeline must not emit personal data to an external unapproved sink. Which change addresses it directly?

  1. Apply governed masking/transformation at the silver promotion boundary
  2. Restrict sink selection and enforce data-classification checks before publishing
  3. Use UC object grants and downstream projection to separate raw and aggregate access
  4. Apply ordered CDC deletion handling to the curated target and downstream purge policy

Explanation

Correct Answer

B:

The requirement concerns “A streaming pipeline must not emit personal data to an external unapproved sink.” The selected operation, Restrict sink selection and enforce data-classification checks before publishing, is the direct engineering control. Its effect can be checked by confirming: An attempted unauthorized export fails under the policy.

Incorrect Answers

A:

The alternative Apply governed masking/transformation at the silver promotion boundary has a distinct purpose—New source rows containing PII must be masked before entering the shared silver table. It would not establish the required outcome (A streaming pipeline must not emit personal data to an external unapproved sink); the necessary verification concerns An attempted unauthorized export fails under the policy.

Which observation supports closure?

  1. A new sensitive column receives the required mask before consumer access
  2. Analysts can query safe aggregate data but are denied direct raw-table access
  3. An attempted unauthorized export fails under the policy
  4. The current serving table no longer contains the erased customer

Explanation

Correct Answer

C:

The team used Restrict sink selection and enforce data-classification checks before publishing to fulfill “A streaming pipeline must not emit personal data to an external unapproved sink.” Observing An attempted unauthorized export fails under the policy confirms the intended effect in the resulting workload.

Incorrect Answers

A:

A new sensitive column receives the required mask before consumer access would demonstrate the separate action Add schema-evolution QA and governed-tag classification checks, which addresses “The team needs to prove masked columns remain protected after a new data column appears.” It does not verify the requirement “A streaming pipeline must not emit personal data to an external unapproved sink” following Restrict sink selection and enforce data-classification checks before publishing.

B:

Analysts can query safe aggregate data but are denied direct raw-table access pertains to a different control (Use UC object grants and downstream projection to separate raw and aggregate access) and a different need (The original raw table must remain in restricted bronze while analysts query safe gold aggregates). It cannot establish that Restrict sink selection and enforce data-classification checks before publishing met the stated goal.

D:

  1. Use UC object grants and downstream projection to separate raw and aggregate access
  2. Add schema-evolution QA and governed-tag classification checks
  3. Apply ordered CDC deletion handling to the curated target and downstream purge policy
  4. Restrict sink selection and enforce data-classification checks before publishing

Explanation

Correct Answer

C:

The requirement concerns “A deletion event arrives after a customer's record was previously emitted.” The selected operation, Apply ordered CDC deletion handling to the curated target and downstream purge policy, is the direct engineering control. Its effect can be checked by confirming: The current serving table no longer contains the erased customer.

Incorrect Answers

A:

Use UC object grants and downstream projection to separate raw and aggregate access belongs to the separate case “The original raw table must remain in restricted bronze while analysts query safe gold aggregates,” where Analysts can query safe aggregate data but are denied direct raw-table access would be expected. That differs from the condition in this stem: “A deletion event arrives after a customer's record was previously emitted.”

B:

Add schema-evolution QA and governed-tag classification checks belongs to the separate case “The team needs to prove masked columns remain protected after a new data column appears,” where A new sensitive column receives the required mask before consumer access would be expected. That differs from the condition in this stem: “A deletion event arrives after a customer's record was previously emitted.”

D:

This action solves a different issue: “A streaming pipeline must not emit personal data to an external unapproved sink.” Its normal signal is An attempted unauthorized export fails under the policy. Here the requested behavior is “A deletion event arrives after a customer's record was previously emitted,” so that signal is not sufficient.

Question 796

A compliance review validates masking and erasure across a streaming data flow. The team implements Apply ordered CDC deletion handling to the curated target and downstream purge policy. The goal was: A deletion event arrives after a customer's record was previously emitted. Which observed result best verifies success?

  1. The current serving table no longer contains the erased customer
  2. A new sensitive column receives the required mask before consumer access
  3. Analysts can query safe aggregate data but are denied direct raw-table access
  4. An attempted unauthorized export fails under the policy

Explanation

Correct Answer

A:

The acceptance criterion for “A deletion event arrives after a customer's record was previously emitted” is The current serving table no longer contains the erased customer; this is the expected evidence after Apply ordered CDC deletion handling to the curated target and downstream purge policy.

Incorrect Answers

B:

That observation is a valid indicator for “The team needs to prove masked columns remain protected after a new data column appears” when using Add schema-evolution QA and governed-tag classification checks. The scenario instead tests “A deletion event arrives after a customer's record was previously emitted”; the relevant result is The current serving table no longer contains the erased customer.

C:

It cannot establish that Apply ordered CDC deletion handling to the curated target and downstream purge policy met the stated goal.

Question 797

A compliance review validates masking and erasure across a streaming data flow. A design review specifies the following target: The team needs to prove masked columns remain protected after a new data column appears. Which action is most appropriate?

  1. Apply ordered CDC deletion handling to the curated target and downstream purge policy
  2. Add schema-evolution QA and governed-tag classification checks
  3. Use UC object grants and downstream projection to separate raw and aggregate access
  4. Apply governed masking/transformation at the silver promotion boundary

Explanation

Correct Answer

B:

The requested outcome is “The team needs to prove masked columns remain protected after a new data column appears.” Add schema-evolution QA and governed-tag classification checks is the matching action; A new sensitive column receives the required mask before consumer access gives observable acceptance evidence.

Incorrect Answers

A:

This action solves a different issue: “A deletion event arrives after a customer's record was previously emitted.” Its normal signal is The current serving table no longer contains the erased customer. Here the requested behavior is “The team needs to prove masked columns remain protected after a new data column appears,” so that signal is not sufficient.

  2. Apply ordered CDC deletion handling to the curated target and downstream purge policy
  3. Add schema-evolution QA and governed-tag classification checks
  4. Apply governed masking/transformation at the silver promotion boundary

Explanation

Correct Answer

A:

Use UC object grants and downstream projection to separate raw and aggregate access addresses the requested condition (“The original raw table must remain in restricted bronze while analysts query safe gold aggregates”) rather than an adjacent platform task. The independent success check is: Analysts can query safe aggregate data but are denied direct raw-table access.

Incorrect Answers

B:

Apply ordered CDC deletion handling to the curated target and downstream purge policy is appropriate when “A deletion event arrives after a customer's record was previously emitted”; it would be verified by The current serving table no longer contains the erased customer. It does not directly satisfy “The original raw table must remain in restricted bronze while analysts query safe gold aggregates,” whose relevant acceptance evidence is Analysts can query safe aggregate data but are denied direct raw-table access.

C:
