Question 320

An architecture proposal for sql migration compatibility decisions relies on the following approach: Delete the source database before measuring migration completeness. Which specific failure or mismatch should the design reviewer identify?

  1. Unsupported instance features can block lift-and-shift.
  2. Offline migrations require an interruption and final transaction cutoff.
  3. Premature deletion destroys rollback options and verification sources.
  4. Dedicated maximum capacity per tenant can waste substantial compute.

Explanation

Correct Answer

C:

Delete the source database before measuring migration completeness. Premature deletion destroys rollback options and verification sources.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Assume a new cloud SQL Database automatically supports every local server feature.' not to the recommendation under review. Here, Premature deletion destroys rollback options and verification sources.

B:

That assessment refers to the separate proposal 'Promise zero downtime from a tool whose selected path is offline-only.' not to the recommendation under review. Here, Premature deletion destroys rollback options and verification sources.

D:

This concern applies to Overprovision every single database for the sum of all hypothetical peaks. in another design data storage solutions for relational data design. The current proposal specifically fails because premature deletion destroys rollback options and verification sources.

Question 321

Acceptance testing must establish the following operational result: Data verification plus rollback readiness establishes safe cutover. Which verification action most directly establishes that outcome?

  1. Inventory Agent jobs, linked servers and engine features in the assessment output.
  2. Compare row counts and application transaction checks before final switch.
  3. Time a nonproduction dress rehearsal and record cutover steps.
  4. Monitor pool utilization and per-database resource consumption over a cycle.

Explanation

Correct Answer

B:

Data verification plus rollback readiness establishes safe cutover.

Incorrect Answers

A:

That verification addresses the different requirement: A company is retiring physical SQL Server hosts and must preserve SQL Agent and instance-level semantics. It does not directly establish data verification plus rollback readiness establishes safe cutover.

C:

That verification addresses the different requirement: A mission-critical database migration seeks near-zero downtime but the target option lacks required online support. It does not directly establish data verification plus rollback readiness establishes safe cutover.

D:

This is a test for A software vendor hosts 60 small customer databases with staggered peak usage. The requirement here is instead demonstrated by compare row counts and application transaction checks before final switch.

Question 322

A mission-critical database migration seeks near-zero downtime but the target option lacks required online support. Which Azure architecture choice best meets this requirement?

  1. Assume a new cloud SQL Database automatically supports every local server feature.
  2. Select a migration method only after validating online/offline capabilities for source and target.
  3. Delete the source database before measuring migration completeness.
  4. Promise zero downtime from a tool whose selected path is offline-only.

Explanation

Correct Answer

B:

Downtime feasibility depends on the supported migration path and replication mode.

Incorrect Answers

A:

Unsupported instance features can block lift-and-shift. In the present requirement, a mission-critical database migration seeks near-zero downtime but the target option lacks required online support. The needed design instead works because downtime feasibility depends on the supported migration path and replication mode.

C:

Premature deletion destroys rollback options and verification sources. In the present requirement, a mission-critical database migration seeks near-zero downtime but the target option lacks required online support. The needed design instead works because downtime feasibility depends on the supported migration path and replication mode.

D:

Offline migrations require an interruption and final transaction cutoff. This proposal contradicts the stated architecture constraint.

Question 323

An architecture proposal for sql migration compatibility decisions relies on the following approach: Promise zero downtime from a tool whose selected path is offline-only. Which specific failure or mismatch should the design reviewer identify?

  1. The VM adds patching and server operations with no stated compatibility requirement.
  2. Offline migrations require an interruption and final transaction cutoff.
  3. Premature deletion destroys rollback options and verification sources.
  4. Unsupported instance features can block lift-and-shift.

Explanation

Correct Answer

B:

Promise zero downtime from a tool whose selected path is offline-only. Offline migrations require an interruption and final transaction cutoff.

Incorrect Answers

A:

This concern applies to Provision a dedicated Windows VM simply to host a small new database. in another design data storage solutions for relational data design. The current proposal specifically fails because offline migrations require an interruption and final transaction cutoff.

C:

That assessment refers to the separate proposal 'Delete the source database before measuring migration completeness.' not to the recommendation under review. Here, Offline migrations require an interruption and final transaction cutoff.

D:

That assessment refers to the separate proposal 'Assume a new cloud SQL Database automatically supports every local server feature.' not to the recommendation under review. Here, Offline migrations require an interruption and final transaction cutoff.

Question 324

Acceptance testing must establish the following operational result: Measured outage establishes credible service objectives. Which verification action most directly establishes that outcome?

  1. Verify automatic backups and managed service connection behavior.
  2. Compare row counts and application transaction checks before final switch.
  3. Time a nonproduction dress rehearsal and record cutover steps.
  4. Inventory Agent jobs, linked servers and engine features in the assessment output.

Explanation

Correct Answer

C:

Measured outage establishes credible service objectives.

Incorrect Answers

A:

This is a test for A new cloud-native API needs one managed relational database without server-level dependencies. The requirement here is instead demonstrated by time a nonproduction dress rehearsal and record cutover steps.

B:

That verification addresses the different requirement: A legacy OLTP app can tolerate a brief cutover but requires schema and data fidelity. It does not directly establish measured outage establishes credible service objectives.

D:

That verification addresses the different requirement: A company is retiring physical SQL Server hosts and must preserve SQL Agent and instance-level semantics. It does not directly establish measured outage establishes credible service objectives.

Question 325

A regulated database needs data encrypted at rest without developers implementing custom column crypto. Which Azure architecture choice best meets this requirement?

  1. Assume NSG inbound rules encrypt persisted database pages.
  2. Make auditors database owners and rely only on SQL server errors.
  3. Use Azure SQL Transparent Data Encryption with supported key management.
  4. Use TDE alone and claim privileged database users cannot read sensitive columns.

Explanation

Correct Answer

C:

TDE protects database files, logs and backups at rest at the engine layer.

Incorrect Answers

A:

Network access controls do not encrypt database storage. This proposal contradicts the stated architecture constraint.

B:

Ownership expands privileges and error logs are not a complete audited access stream. In the present requirement, a regulated database needs data encrypted at rest without developers implementing custom column crypto. The needed design instead works because tDE protects database files, logs and backups at rest at the engine layer.

D:

TDE does not hide decrypted column values from authorized SQL queries. In the present requirement, a regulated database needs data encrypted at rest without developers implementing custom column crypto. The needed design instead works because tDE protects database files, logs and backups at rest at the engine layer.

Question 326

An architecture proposal for sql encryption and access relies on the following approach: Assume NSG inbound rules encrypt persisted database pages. Which specific failure or mismatch should the design reviewer identify?

  1. TDE does not hide decrypted column values from authorized SQL queries.
  2. Ownership expands privileges and error logs are not a complete audited access stream.
  3. Network access controls do not encrypt database storage.
  4. Always-on provisioned compute can waste idle capacity in this scenario.

Explanation

Correct Answer

C:

Assume NSG inbound rules encrypt persisted database pages. Network access controls do not encrypt database storage.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Use TDE alone and claim privileged database users cannot read sensitive columns.' not to the recommendation under review. Here, Network access controls do not encrypt database storage.

B:

That assessment refers to the separate proposal 'Make auditors database owners and rely only on SQL server errors.' not to the recommendation under review. Here, Network access controls do not encrypt database storage.

D:

This concern applies to Keep a large provisioned database running continuously despite the idle workload. in another design data storage solutions for relational data design. The current proposal specifically fails because network access controls do not encrypt database storage.

Question 327

Acceptance testing must establish the following operational result: Configuration proof validates the at-rest control. Which verification action most directly establishes that outcome?

  1. Review pause/resume history and effective compute billing.
  2. Execute a controlled audited query and locate the audit record.
  3. Inspect database encryption state and key configuration.
  4. Run an authorized query without the client encryption key.

Explanation

Correct Answer

C:

Configuration proof validates the at-rest control.

Incorrect Answers

A:

This is a test for A development database receives traffic twice daily and is idle overnight, with tolerance for wake-up latency. The requirement here is instead demonstrated by inspect database encryption state and key configuration.

B:

That verification addresses the different requirement: Security needs SQL audit events centralized without giving auditors table modification privileges. It does not directly establish configuration proof validates the at-rest control.

D:

That verification addresses the different requirement: Developers must not see highly sensitive values even when operating the SQL server. It does not directly establish configuration proof validates the at-rest control.

Question 328

Developers must not see highly sensitive values even when operating the SQL server. Which Azure architecture choice best meets this requirement?

  1. Evaluate Always Encrypted with protected client key access for selected columns.
  2. Assume NSG inbound rules encrypt persisted database pages.
  3. Make auditors database owners and rely only on SQL server errors.
