DP-900Domain 2: Identify Considerations for Relational Data on AzureRelational Data on AzureeasySingle choice
An open-source app built on PostgreSQL must migrate to Azure with minimal code change. Which Azure service hosts it?
A.Azure Database for PostgreSQL
Managed PostgreSQL = direct answer. Correct.
B.Azure SQL Database
Different engine — dialect incompatibilities.
C.Azure Cosmos DB
Cosmos is NoSQL — not relational PostgreSQL.
D.Azure Synapse Analytics
Synapse is analytics warehousing.
Why this answer
Azure offers managed open-source engines: Database for PostgreSQL, MySQL, and MariaDB — lift-and-shift compatible. Azure SQL is Microsoft's engine (T-SQL dialect differences); Cosmos is NoSQL.
