Question 210

At Oakridge Public Services, the citizen data administration team maintains a municipal case-management and application database platform with requirements for reproducible configuration and controlled access. The acceptance review requires independent evidence for: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. 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 approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.
  3. Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.
  4. An authorized application decrypts a test value while a database administrator query sees ciphertext rather than plaintext.

Explanation

Correct Answer

C:

Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values. That observable result supports resolution of: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. The corresponding corrective change is: Use a suitably governed column or application encryption design with key management and limited decrypt permissions. The Oakridge Public Services reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

A supported query performs the approved confidential operation with enclave attestation while plaintext keys remain outside ordinary engine access. That result is evidence for another corrective change: Evaluate Always Encrypted with secure enclaves and the required hardware, driver and database feature support for the intended computations. The alternative problem is: An application requires supported computations on encrypted database columns but is deployed with Always Encrypted columns without enclave capability. The current Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

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 Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

D:

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 Oakridge Public Services issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

Question 211

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. An authorized design review finds: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Which action BEST resolves this specific database administration problem?

  1. Use a suitably governed column or application encryption design with key management and limited decrypt permissions.
  2. Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption.
  3. Configure transparent data encryption with an eligible customer-managed key in Azure Key Vault or managed HSM according to the service rules.
  4. Configure a private endpoint and private DNS with appropriate network rules and disable unnecessary public network access.

Explanation

Correct Answer

A:

Use a suitably governed column or application encryption design with key management and limited decrypt permissions. This addresses the specific Azure SQL or SQL Server operational issue: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. The Meadowbrook Finance team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

Incorrect Answers

B:

Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption. That relates to a separate SQL administration problem: 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 Meadowbrook Finance requirement is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. That approach does not directly establish the required fix; the requested acceptance evidence is: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

C:

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 Meadowbrook Finance requirement is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. That approach does not directly establish the required fix; the requested acceptance evidence is: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

D:

Configure a private endpoint and private DNS with appropriate network rules and disable unnecessary public network access. That relates to a separate SQL administration problem: An Azure SQL Database is reachable through a public endpoint from unrestricted networks even though only an internal application subnet should connect. The Meadowbrook Finance requirement is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. That approach does not directly establish the required fix; the requested acceptance evidence is: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

Question 212

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. After a claimed fix, the release reviewer evaluates: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Which observed result BEST proves the intended problem is corrected?

  1. The approved client reaches the database and a separate outside-IP test is rejected by the Azure SQL network access policy.
  2. Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.
  3. A test connection negotiates the required TLS channel and a deliberately noncompliant client connection is denied.
  4. An authorized application decrypts a test value while a database administrator query sees ciphertext rather than plaintext.

Explanation

Correct Answer

B:

Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values. That observable result supports resolution of: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. The corresponding corrective change is: Use a suitably governed column or application encryption design with key management and limited decrypt permissions.

The current Meadowbrook Finance issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

C:

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 Meadowbrook Finance issue is instead: A database stores customer payment tokens in reversible plaintext even though only a small service needs to decrypt selected fields. Its decisive acceptance evidence would be: Only the approved service returns plaintext from the test column and unauthorized SQL readers cannot recover its sensitive values.

D:

Question 213

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. A routine platform check identifies: An organization opens all inbound traffic to SQL Managed Instance because internal client DNS and subnet routing were never configured. Which action BEST resolves this specific database administration problem?

  1. Replace broad access with the narrow approved client range or private connectivity and remove expired rules after testing.
  2. Require supported encrypted SQL connections and validate server certificates and client driver encryption settings.
  3. Configure the managed instance's supported private connectivity, name resolution and narrow network security group access.
  4. Use Always Encrypted for suitable columns with keys managed outside the database engine and supported client-side encryption.

Explanation

Correct Answer

C:

Configure the managed instance's supported private connectivity, name resolution and narrow network security group access. This addresses the specific Azure SQL or SQL Server operational issue: An organization opens all inbound traffic to SQL Managed Instance because internal client DNS and subnet routing were never configured. The Meadowbrook Finance team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: The authorized private application resolves and connects on permitted ports while a forbidden subnet cannot establish a SQL session.

The corresponding corrective change is: Configure the managed instance's supported private connectivity, name resolution and narrow network security group access. The Alpine Healthcare reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

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 organization opens all inbound traffic to SQL Managed Instance because internal client DNS and subnet routing were never configured. Its decisive acceptance evidence would be: The authorized private application resolves and connects on permitted ports while a forbidden subnet cannot establish a SQL session.

B:

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 Alpine Healthcare issue is instead: An organization opens all inbound traffic to SQL Managed Instance because internal client DNS and subnet routing were never configured. Its decisive acceptance evidence would be: The authorized private application resolves and connects on permitted ports while a forbidden subnet cannot establish a SQL session.

C:

The authorized private application resolves and connects on permitted ports while a forbidden subnet cannot establish a SQL session. That result is evidence for another corrective change: Configure the managed instance's supported private connectivity, name resolution and narrow network security group access. The alternative problem is: An organization opens all inbound traffic to SQL Managed Instance because internal client DNS and subnet routing were never configured. The current Keystone BioLabs issue is instead: A security team assumes a service endpoint automatically gives a database a private IP address inside the application's subnet. Its decisive acceptance evidence would be: A client resolves the expected private endpoint DNS chain and reaches the service over the permitted private route.

D:

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 Keystone BioLabs issue is instead: A security team assumes a service endpoint automatically gives a database a private IP address inside the application's subnet. Its decisive acceptance evidence would be: A client resolves the expected private endpoint DNS chain and reaches the service over the permitted private route.
