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?
Explanation
Correct Answer
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
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.
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.
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.
