Microsoft Azure Fundamentals AZ-900 Practice Question

The correct answer is "Elasticity allows automatic scaling of resources and redundancy minimizes service interruptions."

Elasticity enables the application to automatically adjust its resources in response to varying workloads, ensuring consistent performance during traffic spikes. Redundancy, a key aspect of high availability, ensures that if one component fails, others can take over, minimizing downtime. While cost savings and pay-as-you-go pricing are financial benefits, they do not directly improve performance or reduce interruptions. Advanced security features protect against threats but do not address resource scaling or availability. Global distribution reduces latency but does not inherently handle sudden workload increases or minimize service interruptions due to component failures.
