Microsoft Azure Administrator Associate AZ-104 Practice Question

An Availability Set ensures that virtual machines are distributed across multiple fault domains and update domains within a single data center. This configuration provides redundancy and minimizes the impact of hardware failures or maintenance events. Virtual Machine Scale Sets are used for deploying and managing a set of identical VMs for scalability. Availability Zones distribute VMs across separate physical locations within an Azure region, which is more suitable for protection against data center-level failures. Proximity Placement Groups are used to co-locate VMs for low-latency requirements.
