What is the best way to ensure that IKE/ISAKMP packets are not dropped when QoS is enabled on the uplink interface of the Teleworker router?（）

A.QoS and IPSec should never be used together.

B.IKE/ISAKMP packets are DiffSERV codepoint CS6, so the traffic is never dropped.

C.Source IKE/ISAKMP packets off the loop-back address.

D.Classify IKE/ISAKMP packets so they are appropriately prioritized.
