You have an Azure SQL database that you access directly from the internet.
You recently changed your external IP address.
After changing the IP address, you can no longer access the database. You can connect to other resources in Azure
What is a possible cause of the issue?
- A . a database-level firewall
- B . role-based access control (RSAC)
- C . Dynamic Host Configuration Protocol (DHCP)
- D . Domain Name Service (DNS)
A
Explanation:
The Azure SQL Database firewall lets you decide which IP addresses may or may not have access to either your Azure SQL Server or your Azure SQL database.
When creating an Azure SQL Database, the firewall needs to be configured before anyone will be able to access the database. By default, no external access to your SQL Database will be allowed until you explicitly assign permission by creating a firewall rule.

Which type of data store should you use?
- A . Key/value
- B . Graph
- C . Document
- D . columnar
B
Explanation:
Data as it appears in the real world is naturally connected. Traditional data modeling focuses on defining entities separately and computing their relationships at runtime. While this model has its advantages, highly connected data can be challenging to manage under its constraints.
A graph database approach relies on persisting relationships in the storage layer instead, which leads to highly efficient graph retrieval operations. Azure Cosmos DB’s Gremlin API supports the property graph model.
