A healthcare provider is designing the architecture for a new patient health portal on Microsoft Azure. The portal must be resilient against localized datacenter failures as well as widespread regional outages. The database administrator is configuring regions, Availability Zones, and region pairs to meet these requirements. Which of the following statements regarding these Azure infrastructure components are true? (Select two.)
- Availability Zones are unique physical locations within a single Azure region, each equipped with independent power, cooling, and networking.Cevap
- Azure region pairs are typically located at least 300 miles away from each other to minimize the likelihood of a disaster affecting both regions simultaneously.Cevap
- CAvailability Zones span across multiple separate geographical regions to ensure that if one region goes down, the zone remains available.
- DAll resources deployed in a Resource Group must reside in the same Azure region as the Resource Group itself.
- EDeploying an application across multiple Availability Zones in a single region provides disaster recovery in the event of a total regional outage.
Cevap
Availability Zones are unique physical locations within a single Azure region with independent infrastructure, and Azure region pairs are separated by a minimum physical distance to protect against regional disasters.
The statement describing Availability Zones as unique physical locations within a single Azure region with independent infrastructure, and the statement that Azure region pairs are separated by a minimum physical distance to protect against regional disasters, are correct. These accurately reflect the architectural parameters defined by Microsoft for high availability within a region and disaster recovery across regions.
