Answer Description

Availability Zones are physically separate locations within an Azure region, each with independent power, cooling, and networking. By deploying resources across multiple Availability Zones, your application can continue to operate even if one zone experiences an outage.

Availability Sets protect against hardware failures within a datacenter but do not provide resilience against datacenter failures.

Azure Regional Pairs provide disaster recovery capabilities across different regions, not within the same region.

Azure Traffic Manager is used for DNS-based load balancing and distribution of traffic but does not protect against datacenter failures within a single region.
