B.      The FCoE or Fibre Channel port allocations must be contiguous on the 6200.

C.      10-G Fibre Channel ports only use SFP+ interfaces.

D.      vPC is not supported on the Ethernet ports.


Correct Answer: B




Which statement about the implementation of Cisco TrustSec on Cisco Nexus 7000 Series Switches is true?


A.      While SGACL enforcement and SGT propagation are supported on the M and F modules, 802.1AE (MACsec) support is available only on the M module.

B.      SGT Exchange Protocol is required to propagate the SGTs across F modules that lack hardware support for Cisco TrustSec.
