Although B is the most correct answer; the wording of the answer is incorrect. The answer should read ‘IPFIX **or** sFLOW must be enabled on each physical device’. The reference reads ‘(devices) must be configured to send samples using **one of** those protocols”, so ‘or’ describes this; not ‘and’.
LLDP + LLDP-MED must also enabled
