Question 220
At Keystone BioLabs, the regulated data engineering team maintains a clinical trial and laboratory audit database system with requirements for record confidentiality and strong audit history. The operations owner asks for a validation result for: A security team assumes a service endpoint automatically gives a database a private IP address inside the application's subnet. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
A client resolves the expected private endpoint DNS chain and reaches the service over the permitted private route. That observable result supports resolution of: A security team assumes a service endpoint automatically gives a database a private IP address inside the application's subnet. The corresponding corrective change is: Distinguish service endpoints from Private Link and select private endpoints when private-address access and public exposure reduction are required. The Keystone BioLabs reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
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 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.
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.
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.
