Question 190

At Meadowbrook Finance, the banking data reliability team maintains a financial payments and reporting database environment with requirements for traceable ledger changes and strict access to customer records. The operations owner asks for a validation result for: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Which observed result BEST proves the intended problem is corrected?

  1. An authorized application decrypts a test value while a database administrator query sees ciphertext rather than plaintext.
  2. Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.
  3. A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.
  4. DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing.

Explanation

Correct Answer

C:

A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access. That observable result supports resolution of: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. The corresponding corrective change is: Evaluate Always Encrypted with secure enclaves and the required hardware, driver and database feature support for the intended computations. The Meadowbrook Finance reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

An authorized application decrypts a test value while a database administrator query sees ciphertext rather than plaintext. That result is evidence for another corrective change: Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption. The alternative problem is: A team wants an administrator who can run queries to be unable to see highly sensitive column values, but proposes only transparent data encryption. The current Meadowbrook Finance issue is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Its decisive acceptance evidence would be: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

B:

Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values. That result is evidence for another corrective change: Use a suitably governed column or application encryption design with key management and limited decrypt permissions. The alternative problem is: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. The current Meadowbrook Finance issue is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Its decisive acceptance evidence would be: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

D:

DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing. That result is evidence for another corrective change: Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname. The alternative problem is: A network migration replaces a database's public hostname with a private endpoint but client DNS still resolves the old public address. The current Meadowbrook Finance issue is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Its decisive acceptance evidence would be: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

Question 191

At Alpine Healthcare, the clinical database operations team maintains a hybrid healthcare scheduling and records platform with requirements for patient confidentiality and high service availability. The database operations review identifies: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Which action BEST resolves this specific database administration problem?

  1. Require supported encrypted SQL connections and validate server certificates and client driver encryption settings.
  2. Evaluate Always Encrypted with secure enclaves and the required hardware, driver and database feature support for the intended computations.
  3. Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname.
  4. Configure transparent data encryption with an eligible customer-managed key in Azure Key Vault or managed HSM according to the service rules.

Explanation

Correct Answer

B:

Evaluate Always Encrypted with secure enclaves and the required hardware, driver and database feature support for the intended computations. This addresses the specific Azure SQL or SQL Server operational issue: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. The Alpine Healthcare team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

Incorrect Answers

A:

Require supported encrypted SQL connections and validate server certificates and client driver encryption settings. That relates to a separate SQL administration problem: An application attempts to connect to Azure SQL by unencrypted TDS because it assumes VPN transport replaces all database-layer TLS requirements. The Alpine Healthcare requirement is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. That approach does not directly establish the required fix; the requested acceptance evidence is: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

C:

Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname. That relates to a separate SQL administration problem: A network migration replaces a database's public hostname with a private endpoint but client DNS still resolves the old public address.

That approach does not directly establish the required fix; the requested acceptance evidence is: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

D:

Configure transparent data encryption with an eligible customer-managed key in Azure Key Vault or managed HSM according to the service rules. That relates to a separate SQL administration problem: A regulated Azure SQL Database uses default platform-managed encryption keys but requires customer-controlled key rotation and revocation evidence. The Alpine Healthcare requirement is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. That approach does not directly establish the required fix; the requested acceptance evidence is: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

Question 192

At Alpine Healthcare, the clinical database operations team maintains a hybrid healthcare scheduling and records platform with requirements for patient confidentiality and high service availability. The acceptance review requires independent evidence for: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Which observed result BEST proves the intended problem is corrected?

  1. A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.
  2. The TDE protector becomes operational and a test key rotation completes without key-access or database-availability errors.
  3. Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.
  4. The database reports the intended TDE protector and a controlled key-rotation test completes without application data exposure.

Explanation

Correct Answer

A:

A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access. That observable result supports resolution of: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability.

The Alpine Healthcare reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

B:

The TDE protector becomes operational and a test key rotation completes without key-access or database-availability errors. That result is evidence for another corrective change: Grant the supported least-privilege key permissions or role assignments for the database encryption protector identity. The alternative problem is: A customer-managed TDE deployment points at an Azure Key Vault key but the SQL service identity lacks the required key operations. The current Alpine Healthcare issue is instead: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. Its decisive acceptance evidence would be: A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access.

C:

Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values. That result is evidence for another corrective change: Use a suitably governed column or application encryption design with key management and limited decrypt permissions.

A test connection negotiates the required TLS channel and a deliberately noncompliant client connection is denied. That result is evidence for another corrective change: Require supported encrypted SQL connections and validate server certificates and client driver encryption settings. The alternative problem is: An application attempts to connect to Azure SQL by unencrypted TDS because it assumes VPN transport replaces all database-layer TLS requirements. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.

B:

The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy. That result is evidence for another corrective change: Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing. The alternative problem is: A team allows the Azure SQL server-wide firewall rule for every address just to support one temporary developer laptop. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.

C:

DNS queries from approved clients resolve the private endpoint address and the SQL login succeeds without public routing. That result is evidence for another corrective change: Configure the correct private DNS zone linkage or conditional forwarding for the Azure SQL private endpoint hostname. The alternative problem is: A network migration replaces a database's public hostname with a private endpoint but client DNS still resolves the old public address. The current Riverton Utilities issue is instead: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. Its decisive acceptance evidence would be: An approved private client connects using the intended private address and an unapproved external connection fails.
