Important Microsoft DP-800 Exam Questions

Answer: D

Explanation:

The requirement is very specific: prevent ddl_Audit from firing during the next deployment, but leave the trigger object in place. Microsoft documents DISABLE TRIGGER as the statement used to disable a trigger without dropping it. That is exactly the right operation for a temporary suspension of a DDL trigger. For a database-scoped DDL trigger, the syntax is on the database scope, for example DISABLE TRIGGER ddl_Audit ON DATABASE;.

The other options do not meet the requirement as directly:

ALTER TRIGGER changes the trigger definition, not simply disables execution.

ALTER DATABASE is not the direct statement for disabling a specific DDL trigger.

ALTER SERVER AUDIT SPECIFICATION and ALTER DATABASE AUDIT SPECIFICATION are audit-feature statements, not trigger-control statements.

So the correct Transact-SQL statement is DISABLE TRIGGER.

Answer: B

Explanation:

The requirement says the stored values and query inputs must both be protected, and users must not be able to infer relationships or repetitions in the data from the encrypted output. Microsoft documents that deterministic encryption always produces the same ciphertext for the same plaintext, which allows equality comparisons but also leaks patterns. By contrast, randomized encryption produces a different encrypted value each time for the same plaintext, which improves security and prevents pattern analysis based on repeated ciphertext values.

That makes randomized encryption the right choice here:

It protects data at rest and in transit/query parameters under Always Encrypted's client-side encryption model.

It prevents attackers from learning that the same plaintext value appears repeatedly, because repeated inputs do not produce repeated ciphertext.

Why the other options are wrong:

A . Always Encrypted with secure enclaves adds richer confidential query support, but the key protection property the question is testing is the encryption type. The requirement to prevent inference from repeated ciphertext points specifically to randomized encryption.

C . RLS controls row access, not value confidentiality.

D . Deterministic encryption allows equality-based operations but leaks repetition patterns, which the question explicitly forbids.

Answer: B

Explanation:

This does not meet the goal. A row-by-row DELETE against the oldest month is not the lowest-impact way to purge data from a monthly partitioned table. Microsoft's partitioning guidance specifically says partitioning lets you perform maintenance and retention operations more efficiently by targeting just the relevant partition, including the ability to truncate data in a single partition.

The proposed statement:

DELETE FROM dbo.Orders WHERE OrderDate < DATEADD(month, -36, SYSUTCDATETIME());

would log row deletions and can hold locks longer, creating more overhead for other queries than a partition-level maintenance operation. Since the table is already partitioned by month, the expected low-impact approach is to operate on the oldest partition directly, not issue a broad delete predicate over rows. Microsoft explicitly highlights partition-targeted truncation as a faster, more efficient retention operation than working against the whole table or rowset.

Answer: D

Explanation:

The correct answer is D because the policy explicitly prohibits sharing customer PII, secrets, and query result sets with any AI service. The safe way to use GitHub Copilot Chat here is to provide only schema-level information such as table names, column names, relationships, and the required procedure behavior, without sharing actual table contents or result sets. That lets Copilot help generate and review the Transact-SQL while avoiding disclosure of customer data. This is consistent with Microsoft and GitHub guidance that content provided in prompts is what the AI can use, so avoiding real data in the prompt is the appropriate control.

The other options violate the requirement:

A pastes real rows containing email addresses, which is direct PII disclosure.

B shares actual query result sets, which the policy forbids.

C provides the connection string so Copilot can validate against the database, which is inappropriate because it exposes connection details and could enable access beyond schema-only assistance.

So the correct approach is to ask Copilot to generate the stored procedure using only the schema and requirements, not real customer data.

Answer: A

Explanation:

GitHub documents that repository custom instructions for Copilot Chat can be disabled for your own use in the editor settings, and that doing so does not affect other users. In VS Code, this is controlled through settings related to instruction files, where you can disable the use of repository instruction files for your own environment.

The other options are incorrect:

B is not a documented mechanism for disabling repository-level Copilot instructions.

C would remove the repository instruction file itself and therefore affect everyone using that repository, which violates the requirement.
