Exam AZ-900 topic 1 question 37 discussion

Availability Regions contain Availability Zones (Datacenters). If you have a mission-critical app that your customers require access to frequently, you would want redundancy for your databases, meaning you would like to have copies of databases spread across different yet nearby AZs. Hence, in an event of a failure, your AZ should have "Fault Tolerance" Capability.

A is correct

Fault tolerance ensures that a system continues to function even if some of its components fail. In the context of Azure, this means deploying servers across multiple Availability Zones or using Azure Site Recovery to maintain availability in case of a data center failure. This strategy prevents downtime due to a single point of failure in one Azure region.

Fault Tolerance refers to the ability of a system or application to continue operating without disruption in the event of a failure. This is achieved through redundancy and failover mechanisms that ensure that if one component fails, another component takes over seamlessly, without any downtime or interruption of service.

A is correct Fault Tolerance Fault tolerance is about maintaining operations during a failure. Reliability is about minimizing failures over time.

Fault Tolerance is correct. Elasticity and Scalability are not definitions for avaialbility of the servers. I was thinking on low latency but Fault Tolerance capability is key on Availability zones or Datacenters.

A - Fault Tolerance

A - Fault Tolerance

Fault tolerance refers to a system's ability to continue functioning even in the event of a failure or error. This means that the system can detect and recover from faults or errors without causing a complete shutdown or failure

Fault Tolerance will be the correct anser as it ensures you have other Datacentres runningif the existing one goes offline.

a is correct

A es la respuesta correcta

A. Fault tolerance

Fault tolerance is the answer here. Without the tolerance you have no fail over. Elastic and Scale is about adjusting resources available. Low latency is speed related.
