Box 1: A Recovery Services vault
A Recovery Services vault is an entity that stores all the backups and recovery points you create over time.
Box 2: A backup policy
What happens when I change my backup policy?
When a new policy is applied, schedule and retention of the new policy is followed.

A Recovery Services vault is a storage entity in Azure that houses data. The data is typically copies of data, or configuration information for virtual machines (VMs), workloads, servers, or workstations. You can use Recovery Services vaults to hold backup data for various Azure services such as IaaS VMs (Linux or Windows) and Azure SQL databases.
You can use backup policy to configure schedule.

Explanation:

To allow VNet1 (192.168.8.0/24) and VNet2 (192.168.9.0/24) to communicate, the lowest-overhead Azure- native option is virtual network peering. Azure documentation describes VNet peering as a way to connect two VNets so that resources can communicate using private IP addresses as if they were on the same network.
Because the address spaces do not overlap, peering is supported and does not require deploying extra appliances. This also minimizes administrative effort compared to routing through gateways or NVAs.
For on-premises to Azure connectivity while minimizing cost, the appropriate service is an Azure VPN Gateway with a site-to-site (S2S) VPN. Azure's guidance for hybrid connectivity positions VPN Gateway as the cost-effective encrypted tunnel over the public internet for connecting on-premises networks to Azure VNets. The alternative shown, ExpressRoute, provides private dedicated connectivity but is designed for higher throughput/enterprise requirements and generally increases cost due to circuit provisioning and associated charges. Therefore, combining VNet peering (VNet-to-VNet) with VPN Gateway (on-prem-to- Azure) satisfies both communication requirements and the cost constraint.

Box 1: storageaccount1 and storageaccount2 only
Box 2: All the storage accounts
Note: The three different storage account options are: General-purpose v2 (GPv2) accounts, General-purpose v1 (GPv1) accounts, and Blob storage accounts.
General-purpose v2 (GPv2) accounts are storage accounts that support all of the latest features for blobs, files, queues, and tables.
Blob storage accounts support all the same block blob features as GPv2, but are limited to supporting only block blobs.
General-purpose v1 (GPv1) accounts provide access to all Azure Storage services, but may not have the latest features or the lowest per gigabyte pricing.
