Zorluk: OrtaDesign Relational Database HA and DR

A company is planning to migrate an on-premises database to Azure. The database relies on SQL Server Agent jobs and cross-database queries. The migrated database must meet the following requirements:
- Provide high availability and automatic failover to a paired secondary region.
- Do not require modifications to the application connection strings during a failover.
- Support offloading read-only reporting queries to the secondary region.

Which two options should you include in the design to meet the requirements? (Select two.)

  1. Azure SQL Managed Instance as the database deployment optionCevap
  2. An auto-failover group configured for the database instancesCevap
  3. C
    Azure SQL Database single database as the database deployment option
  4. D
    Active geo-replication configured between database servers

Cevap

The design must include Azure SQL Managed Instance and an auto-failover group.
To meet the requirements, the design must use Azure SQL Managed Instance because it supports SQL Server Agent and cross-database queries, which are legacy features from the on-premises environment. Additionally, configuring an auto-failover group ensures automatic failover and provides read-write and read-only listener endpoints that prevent the need to modify application connection strings during a failover.

Adım Adım Çözüm

1
Analyze legacy feature requirements of the on-premises database.
Identify SQL Server Agent and cross-database queries as key features.
These features are only natively supported in Azure SQL Managed Instance or SQL Server on Azure VMs, ruling out Azure SQL Database single database.
2
Evaluate high availability and disaster recovery requirements.
Identify the need for automatic failover, no connection string modifications, and read-only reporting offload.
Auto-failover groups provide automatic failover and unique listeners (read-write and read-only) that automatically route traffic to the appropriate region without client-side updates.

Anahtar Kavram

Selecting the appropriate Azure SQL deployment option based on legacy feature requirements and configuring auto-failover groups for seamless multi-region HA/DR with read-scale routing.
