Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company uses Azure SQL Database with Transparent Data Encryption (TDE) and a customer-managed key stored in Azure Key Vault. The Key Vault is configured with a firewall that denies all public access. The SQL server must be able to access the key. What additional configuration is necessary?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Enable trusted Microsoft services on the Key Vault firewall
Correct. Enabling 'Allow trusted Microsoft services to bypass the firewall' on the Key Vault allows Azure SQL Database to access the key even with the firewall enabled.
B
Distractor review
Create a private endpoint for Key Vault
A private endpoint is one method to allow private access, but it is not required. The trusted services setting is a simpler and often sufficient solution. The question asks 'what additional configuration is necessary?' The trusted services setting is typically the easiest path.
C
Distractor review
Assign the SQL server's managed identity to the Key Vault
Assigning the managed identity and granting key permissions is necessary for authorization but does not solve the network firewall issue. The firewall must be configured to allow access from trusted services.
D
Distractor review
Configure a service endpoint on the SQL server
Service endpoints are for connecting from virtual networks to Azure services, not for accessing Key Vault from SQL Database. SQL Database is a PaaS service, not a resource in a VNet.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Enable trusted Microsoft services on the Key Vault firewall — When Key Vault has a firewall enabled (deny all public access), Azure SQL Database (a trusted Microsoft service) can bypass the firewall if the 'Allow trusted Microsoft services to bypass the firewall' setting is enabled on Key Vault. This setting allows specific Azure services that are trusted by Microsoft to access the Key Vault even when public access is denied. This is the simplest solution. Private endpoints are an alternative but not the only required configuration. The SQL server's managed identity must be granted key permissions separately (e.g., Get, Wrap, Unwrap).
