You are developing a solution that performs real-time analysis of IoT data in the cloud. The solution must remain available during Azure service updates. You need to recommend a solution. Which two…

Deploying to two separate regions that are not paired still offers redundancy, but paired regions are specifically optimized for coordinated updates and disaster recovery scenarios, making them more suitable.

Deploying an Azure Stream Analytics job to each region in a paired region provides regional redundancy, as Azure service updates are typically rolled out to only one region of a pair at a time, ensuring the other remains operational.

Monitoring jobs in both regions for failure is essential for high availability, allowing for immediate detection of issues in either region and enabling prompt failover or intervention to maintain continuous service.

Monitoring jobs only in the primary region is insufficient for a highly available solution, as failures in the secondary region would go unnoticed, compromising failover capability.

Deploying an Azure Stream Analytics job to only one region in a paired region does not provide the necessary redundancy for high availability, making the service vulnerable to single-region outages or updates.
