Exam VMCE v12 topic 1 question 43 discussion

When your infrastructure includes a Fibre Channel SAN where the VMware VMs are located, the recommended proxy transport mode to use in Veeam Backup & Replication is the "SAN (Direct Storage Access)" mode. Why SAN (Direct Storage Access)? Efficient Data Transfer: The SAN mode allows Veeam to directly access the storage via the Fibre Channel connection, bypassing the ESXi hosts. This minimizes the load on the network and ESXi resources, which is particularly beneficial when you have large virtual machines or high-performance storage environments. Direct Access to Data: Since the data is retrieved directly from the SAN, it ensures faster backup speeds and reduces the impact on your VMware hosts during backup operations.

The Virtual Appliance (HotAdd) mode uses the ESXi host to access the VM’s disks, which could still impact the production environment. This is not as efficient as Direct Storage Access for Fibre Channel SAN environments.

In the Direct SAN access transport mode, Veeam Backup & Replication leverages VMware VADP to transport VM data directly from and to FC, FCoE and iSCSI storage over the SAN. VM data travels over the SAN, bypassing ESXi hosts and the LAN. The Direct SAN access transport method provides the fastest data transfer speed and produces no load on the production network. https://helpcenter.veeam.com/docs/backup/vsphere/direct_san_access.html?ver=120

I think is C, because virtual appliance still uses resources of esx server.

C is understandable, but the question gives no information regarding the availability of a physical server that is connect to the Fibre Channel SAN. It should be D
