20+ practice questions focused on Identify considerations for relational data on Azure — one of the most tested topics on the Microsoft Azure Data Fundamentals DP-900 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Identify considerations for relational data on Azure PracticeA startup is developing a web application that requires a relational database with PostgreSQL compatibility. They want a fully managed service that automatically handles backups, patching, and provides high availability with a 99.99% SLA. Which Azure service should they choose?
Explanation: Azure Database for PostgreSQL is the correct choice because it is a fully managed relational database service that offers PostgreSQL compatibility, automatic backups, patching, and high availability with a 99.99% SLA. This meets the startup's requirements for a managed PostgreSQL solution without the need for manual administration.
A retail company runs an e-commerce platform on a single SQL Server database. The database experiences unpredictable spikes in read-only reporting queries that degrade transactional performance. They want to migrate to Azure SQL Database and isolate the reporting workload while ensuring it sees the most current data. Which feature should they enable?
Explanation: Read Scale-out offloads read-only reporting queries to a readable secondary replica, which is kept up-to-date via asynchronous replication. While there is a small replication lag, the secondary provides transactionally consistent data with minimal delay, effectively isolating reporting workload from the primary without degrading transactional performance.
A company has an Azure SQL Database that supports a critical business application in the West US region. They want to ensure that if the primary region becomes unavailable, the database can automatically fail over to a secondary replica in the East US region with minimal data loss. The secondary replica must also be readable to offload some reporting queries when the primary is healthy. Which Azure SQL Database feature should they enable?
Explanation: The scenario requires automatic failover with minimal data loss and a readable secondary. Active Geo-Replication provides a readable secondary but requires manual or scripted failover, not automatic. Long-term retention backups, TDE, and Point-in-time restore do not provide geo-replication or automatic failover. The correct Azure feature is Auto-Failover Groups, which offers automatic failover, a single endpoint, and readable secondaries. However, this feature is not listed among the options.
A company runs a critical OLTP application on a single Azure SQL Database in the West US region. They need to ensure high availability with automatic failover to a secondary region in case of a regional outage. The solution must minimize data loss and allow the secondary database to be readable for reporting queries when the primary is healthy. Which feature should they enable?
Explanation: Failover groups with an automatic failover policy enable Azure SQL Database to replicate data asynchronously to a secondary region, ensuring zero data loss during a planned failover (by waiting for synchronization) and minimal data loss during an unplanned failover. The secondary database is readable for reporting queries when the primary is healthy, meeting both the high availability and read-scale requirements. This feature is specifically designed for cross-region disaster recovery with automatic failover, unlike other options that address security, backup retention, or performance tuning.
A company is evaluating deployment options for a new business application that requires a fully managed relational database. The application must support high availability with automatic failover and horizontal scaling for read-heavy workloads. The development team wants to minimize administrative overhead and prefers a PaaS solution that offers built-in read scale-out. Which Azure SQL deployment option should they choose?
Explanation: Azure SQL Database (single database) is the correct choice because it is a fully managed PaaS relational database that supports high availability with automatic failover (99.99% SLA) and built-in read scale-out via read-only replicas (Active Geo-Replication and failover groups). It minimizes administrative overhead by handling patching, backups, and replication automatically, and it allows horizontal scaling for read-heavy workloads by offloading read traffic to secondary replicas without manual configuration.
