Which approach would fulfill these requirements?

• A.Implement PIM-SM and SSM with SSM maps to support IGMPv2 clients
• B.Assign group addresses in the 224/4 range and implement PIM-DM
• C.Implement MLD
• D.Implement bidirectional PIM

Exhibit.

You are authenticating user devices connected to your ex Series switch. You have 802.1X and MAC RADIUS configured for all ports A user is complaining about the time it takes to connect their non-802.1X device on ge-0/0/15 using MAC RADIUS authentication Referring to the exhibit, what should be done to accelerate the authentication process?

• A.Configure the no-reauthentication feature for 802.1X on ge-0/0/15
• B.Change the 802.1X retry attempts value to 5 on ge-0/0/15
• C.Configure the restrict feature for MAC RADIUS on ge-0/0/15.
• D.Change the supplicant mode to multiple on ge-0/0/15

A BA classifier, input policer, and a multifield classifier are applied to an interface in which order are these features processed?

• A.BA classifier -> multifield classifier -> policer
• B.policer > multifield classifier -> BA classifier
• C.multifield classifier -> BA classifier -> policer
• D.policer -> BA classifier -> multifield classifier
