A retail company is deploying a point-of-sale (POS) synchronization service to Azure. To protect the service from a natural disaster that could impact an entire geographic region, the architect proposes deploying the service across two Availability Zones within the same Azure region. The architect asserts that Availability Zones are located at least 300 miles apart to ensure regional disaster recovery. Is this statement regarding Azure Availability Zones true or false?
Answer: Answer
Answer
The statement is false because Azure Availability Zones are located within the same region to ensure low-latency connections, whereas Azure Region Pairs are separated by at least 300 miles to protect against regional disasters.
The statement is false because Azure Availability Zones are designed for high availability and local datacenter isolation within a single region, not for regional disaster recovery. To support low-latency communication, they are located relatively close to each other. Region-wide disaster recovery is instead achieved by using Azure Region Pairs, which are separated by at least 300 miles to minimize the impact of regional disasters.
