What three steps are necessary to enable Jumbo Frames for use with an iSCSI storage array? (Choose three.)
A.
Configure the MTU on the physical switch.
B.
Configure the MTU on the virtual switch.
C.
Configure the MTU on the VTEP.
D.
Configure the MTU on the LAG group.
E.
Configure the MTU on the VMKernel port.
From https://communities.vmware.com/thread/415873
Physical switch: change to MTU on the iSCSI VLAN to 9000. This should not affect anything.
Virtual switch : change the MTU on the vSwitches connecting to the Vmkernels for iSCSI. Should also not disturb anything.
Vmkernel iSCSI adapters : change the MTU to 9000
So this should be A, B and E ..

A B E
I suppose A B E

Agreed, A B E would be correct. D iSCSI should not be setup on a LACP LAG. C VXLAN Tunnel End Point (VTEP) which contains all the functionality needed to provide Ethernet layer 2 services to connected end systems. iSCSI operates on the Session layer — layer 5 — of the ISO OSI model.
I definitely sure A B and E, because I am System Integrator.
