Answers
Suggested answer: A

Explanation:

"both VSX switches as a PIM Designate Router (DR). One node is the actual DR, the other node is the proxy DR." "Only the actual DR performs multicast routing and forward traffic destined to groups to its downstream VLANs in the data-path." https://www.arubanetworks.com/techdocs/AOSCX/ 10.07/HTML/5200-7888/Content/Chp_Pre_tra_loss/ip-mul-rou-10.htm

Suggested answer: C

Explanation:

Radius service tracking locates the availability of the RADIUS service configured on the switch. It helps to minimize the waiting period for new clients in the unauth-vid (Guest Vlan) when authentication fails because of service is not available, as well as previously authenticated clients in unauth-vid (Guest Vlan) when re-authentication fails because service is not available during the reauthentication period. Note that this feature is disabled by default.
