Which two statements are true regarding iSCSI adapters? (Choose two.)
The correct answer is A. Software iSCSI adapters require vmkernel networking. B. Independent Hardware iSCSI adapters offload processing from the ESXi host. Software iSCSI relies on vmkernel networking for its TCP/IP stack, while Independent Hardware iSCSI adapters have a self-contained stack that offloads all iSCSI and network processing from the ESXi host.

Why each option
Software iSCSI relies on vmkernel networking for its TCP/IP stack, while Independent Hardware iSCSI adapters have a self-contained stack that offloads all iSCSI and network processing from the ESXi host.
Software iSCSI uses the ESXi host's native TCP/IP networking stack, which is exposed through vmkernel ports - without a bound vmkernel adapter, the software initiator cannot route iSCSI traffic.
Independent Hardware iSCSI (iHBA) adapters contain a dedicated processor and their own full TCP/IP and iSCSI stack, offloading all related computation from the ESXi host CPU and removing the need for vmkernel networking.
Dependent Hardware iSCSI adapters rely on the host's NIC hardware but still use the ESXi TCP/IP stack and therefore do require vmkernel networking to be configured.
Independent Hardware iSCSI adapters manage their own TCP/IP stack entirely on the card and do not require vmkernel networking, making this statement false.
