Which two types of adapters must the administrator configure? (Choose two.)
To configure remote direct memory access (RDMA) over Converged Ethernet v2 (RoCE v2), two main types of adapters are required. The RDMA network adapter is essential for providing the necessary hardware support for RDMA operations, enabling efficient data transfers with low latency over Ethernet networks. Additionally, a Software NVMe over RDMA storage adapter is required for enabling the direct memory access technology, especially to facilitate communication with NVMe storage devices using RDMA. Therefore, these two adapters are crucial for achieving the desired RDMA functionality over Converged Ethernet v2.
B and D looks right answers

AB is right answer
For RoCE v2, you need at least : - Network adapter that supports RDMA over Converged Ethernet (RoCE v2) - Software NVMe over RDMA adapter Source : https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-storage/GUID-9AEE5F4D-0CB8-4355-BF89-BB61C5F30C70.html
Option A and B are the correct types of adapters that support RDMA over Converged Ethernet v2 (RoCE v2).
A. Paravirtual RDMA adapter: This type of adapter is a virtualized adapter that provides optimized support for RDMA within certain virtualization platforms. However, it is not a standard type of adapter used for RDMA over Converged Ethernet (RoCE v2) in physical environments. B. RDMA network adapter: This is the correct type of adapter for RoCE v2. RDMA network adapters have hardware support for RDMA operations, enabling efficient data transfers with low latency over Ethernet networks. C. Software iSCSI adapter: This type of adapter is used for iSCSI storage communication, not for RDMA over Converged Ethernet. D. Fibre Channel over Ethernet (FCoE) adapter: This type of adapter allows encapsulation of Fibre Channel traffic over Ethernet networks, but it is not used for RDMA over Converged Ethernet. E. Software NVMe over RDMA storage adapter: This type of adapter enables NVMe over RDMA, which allows direct access to NVMe storage devices using RDMA technology, but it is not directly related to RDMA over Converged Ethernet.
I agree: "RDMA allows direct memory access from the memory of one computer to the memory of another computer without involving the operating system or CPU. The transfer of memory is offloaded to the RDMA-capable Host Channel Adapters (HCA) . A PVRDMA network adapter provides remote direct memory access in a virtual environment" Option A, the PVRDMA is required to establish the connection and in virtual environments and option B, the RDMA physical adapter is required for the connection between separate ESXi, this as per KB: https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-9AADBB49-876E-4E44-8149-D0523D8ADA6A.html?hWord=N4IghgNiBcIEoBECyBBABAewG4FMBOacGAwgKJoBqATCAL5A
B E is correct. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-storage/GUID-F4B42510-9E6D-4446-816A-5012866E0038.html
Paravirtual RDMA adapters are not directly related to RoCE v2 configuration, and software iSCSI and Fibre Channel over Ethernet (FCoE) adapters are not specifically required for configuring RDMA over Converged Ethernet v2 (RoCE v2)
I answered BE on the exam. Passed with 428.
BE is the correct answer
B,E - ESXi 7 and later supports RoCE v2 technology, which enables RDMA over an Ethernet network. Hosts use an RDMA network adapter installed on the host and a software NVMe over RDMA storage adapter.
