Correct answer: A
A.
Azure Availability Zones are physically separate locations within a single Azure region. Each zone is made up of one or more data centers equipped with independent power, cooling, and networking. The purpose of Availability Zones is to ensure high availability and fault tolerance within a region. If one zone goes down, the others remain unaffected, ensuring that applications and services remain operational.
B.
This describes Geo-redundant storage (GRS) or using geographically paired regions, not Availability Zones. GRS replicates data to a secondary region, whereas Availability Zones ensure redundancy within a region.
C.
Replication between regions refers to Azure Site Recovery or cross-region replication, which is a separate feature designed for disaster recovery across regions, not Availability Zones within a single region.
D.
While Azure offers many security services, including Network Security Groups (NSGs) and Azure Active Directory, Availability Zones are not primarily a security feature. They focus on fault tolerance and high availability, not security.
