The licenses are applied to the MAC address of the Cisco DCMN system
The licenses are applied using the Cisco DCNM.
VACLs support which two actions? (Choose two.)
Which function does the graceful restart feature allow a Cisco Nexus 7000 Series router to perform?
Remain in the data forwarding path through a process restart.
Which two reasons explain why a server on VLAN 10 is unable to join a multicast stream that originates on VLAN 20? (Choose two.)
IGMP snooping and mrouter are not enabled on VLAN 10.
The mrouter on VLAN 20 does not see the PIM join.

The peer device does not support LLDP.
Unexpected DCBX negotiation occurred with the peer device.
Which Cisco Nexus platform security feature provides an intelligent and scalable access control solution that mitigates security access risks across the entire network?
Which two issues explain why a packet is not being routed as desired in a policy-based routing configuration? (Choose two.)
The next hop that is configured in the route map is not in the global routing table.
The next hop that is configured in the route map has a higher metric than the default next hop.
Which two options are roles of the authentication server in Cisco TrustSec? (Choose two.)
verifies the identities of the supplicant that are part of the Cisco TrustSec
authenticates the user if the supplicant is an endpoint device
Which two enhanced Ethernet features are required for FCoE? (Choose two.)
