You are meeting with the CIO to discuss your VDC design. They question the amount of capital
that is being invested in iSCSI adapters. They state that, because of the number of adapters
required, it is more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated
hypervisor software stack.
How should you justify the increased cost of the iSCSI Adapters?

A.
Using NICs and the software stack will increase CPU load on each hypervisor, requiring more
hypervisors to deliver the same performance levels. This will result in additional hardware and
licensing costs.

B.
iSCSI adapters can encrypt iSCSI frames, preventing unauthorized access to the data. The
hypervisor software stack cannot encrypt iSCSI frames, leaving the data vulnerable.

C.
Using NICs and the software stack will require additional NICs for each hypervisor to deliver the
same throughput. To obtain the additional PCIe slots for the NICs, larger form-factor servers will
be required, increasing hardware costs.

D.
iSCSI adapters can use Jumbo Frames, providing improved performance for storage traffic.
The hypervisor software stack cannot use Jumbo Frames, resulting in poorer performance.
