Question 1

Which Azure SQL Database feature enables automatic failover to a secondary database in a different region with minimal data loss?

Accepted Answer

Active geo-replication

Answer

Active geo-replication continuously replicates an Azure SQL Database to up to four readable secondary databases in different regions, and supports manual or automatic failover.

Question 2

What is the maximum number of fault domains supported by an Azure Availability Set?

Accepted Answer

3

Answer

Azure Availability Sets support up to 3 fault domains, which correspond to separate physical racks with independent power and network within a datacenter.

Question 3

A web application must remain available even if an entire Azure datacenter fails. Which redundancy option should be used?

Accepted Answer

Deploy VMs across Availability Zones in the same region

Answer

Availability Zones are physically separate datacenters within a region, so deploying VMs across multiple zones ensures availability even if one entire datacenter fails.

Question 4

Which Azure Cosmos DB feature provides automatic failover to a secondary region with zero data loss?

Accepted Answer

Multi-region writes (multi-master) configuration

Answer

Multi-region writes (multi-master) in Azure Cosmos DB allow writes to any region, and with bounded staleness or strong consistency, automatic failover occurs with no data loss.

Question 5

What type of Azure Site Recovery failover should you use to test your DR plan without impacting production workloads?

Accepted Answer

Test failover

Answer

Test failover in Azure Site Recovery spins up replicated VMs in an isolated network, allowing validation of the DR plan without affecting production or causing replication to pause.
