Explanation
Box 1: Yes
By moving much of Azure's software-defined networking stack off the CPUs and into FPGA-based SmartNICs, compute cycles are reclaimed by end user applications, putting less load on the VM, decreasing jitter and inconsistency in latency.
Box 2: Yes
Box 3: No
Accelerated Networking (AN) is generally available (GA) and widely available for Windows and the latest distributions of Linux References:

The Azure network functionality used is:
* Azure virtual networks are connected to the ExpressRoute circuit that connects to your on-premises network assets.
* An ExpressRoute circuit that connects on-premises to Azure should have a minimum bandwidth of 1 Gbps or higher. This minimal bandwidth allows adequate bandwidth for the transfer of data between on-premises systems and systems that run on VMs. It also allows adequate bandwidth for connection to Azure systems from on-premises users.
* All SAP systems in Azure are set up in virtual networks to communicate with each other.

If you want to move an existing deployed system from another relational database management system (RDBMS) to HANA. SAP provides reports to run on your existing SAP system. If the database is moved to HANA, these reports check the data and calculate memory requirements for the HANA instance.
/SDF/HDB_SIZING is a standard Executable ABAP Report available within your SAP system (depending on your version and release level).

Explanation:
Box 1: No
To log in to a Linux VM with Azure AD credentials, install the Azure Active Directory login VM extension.
Note: Azure AD Connect is the Microsoft tool designed to meet and accomplish your hybrid identity goals.
Box 2: Yes
If you deploy SAP VMs in a cross-premises scenario, where on-premises Active Directory and DNS are extended in Azure, it is expected that the VMs are joining an on-premises domain.
Box 3: No
