The Microsoft Azure Site Recovery Provider is a component that must be installed on each on-premises Hyper-V host whose virtual machines you intend to replicate to Azure. This provider coordinates and manages replication for all the VMs on that specific host. The scenario describes two Hyper-V hosts, Server1 and Server2, both containing VMs that need to be protected. Therefore, to enable replication for all VMs across both servers, the provider must be installed on each host, resulting in a minimum of two installations.

A: Installing only one provider would leave the virtual machines on the second Hyper-V host unprotected, as it would not be registered with the Recovery Services vault.

C: The provider is installed at the Hyper-V host level, not on each individual virtual machine. The number of VMs (five) is irrelevant to the provider count.

D: This number incorrectly sums the hosts and virtual machines. The provider is only required on the two Hyper-V hosts, not the VMs.

1. Microsoft Learn. (2024). Tutorial: Set up disaster recovery for Hyper-V VMs to Azure. In the "Prepare on-premises Hyper-V hosts" section

under Step 3 "Install the Provider

" the instruction states: "Run the installer on each Hyper-V host you want to register in the site." This confirms the per-host requirement.

2. Microsoft Learn. (2024). Replicate Hyper-V virtual machines (without VMM) to Azure. In the "Step 2: Prepare Hyper-V hosts" section

the documentation specifies: "Download and install the Microsoft Azure Site Recovery Provider on each Hyper-V host." This explicitly states the need for one provider per host.

3. Microsoft Learn. (2023). Hyper-V to Azure disaster recovery architecture. The architecture diagram and accompanying text under the "Architectural components" table describe the "Azure Site Recovery provider" as being installed on on-premises Hyper-V servers to enable registration and orchestration.
