When setting up the iSCSI software initiator on an ESX Server, which virtual switch port types are required? (Choose Two.)

A.
iSCSI

B.
virtual machine

C.
Service Console

D.
VMkernel

Explanation:
With the software-based iSCSI implementation, you can use standard network adapters to connect your ESX/ ESXi host to a remote iSCSI target on the IP network. The software iSCSI initiator that is built into ESX/ESXi facilitates this connection by communicating with the network adapter through the network stack.

Before you configure the software iSCSI initiator, you must perform the following tasks:
1 Create a VMkernel port for physical network adapters. [D above] 2 Enable the software iSCSI initiator.
3 If you use multiple network adapters, activate multipathing on your host using the port binding technique.
4 If needed, enable Jumbo Frames. Jumbo Frames must be enabled for each vSwitch through the vSphere
CLI. Also, if you use an ESX host, you must create a VMkernel network interface enabled with Jumbo Frames.

Networking Configuration for Software iSCSI Storage

Server Configuration Guide : Networking Scenarios and Troubleshooting : Networking Configuration for Software iSCSI Storage

The storage you configure for an ESX Server host might include one or more storage area networks (SANs) that use iSCSI, which is a means of accessing SCSI devices and exchanging data records using TCP/IP protocol over a network port rather than through a direct connection to a SCSI device. In iSCSI transactions, blocks of raw SCSI data are encapsulated in iSCSI records and transmitted to the requesting device or user. Before you can configure iSCSI storage, you must create a VMkernel port to handle iSCSI networking and a service console connection to the iSCSI network. [C and D above].
