Which set of steps accomplishes these goals?

An ACI engineer is implementing a Layer 3 out inside the Cisco ACI fabric that must meet these requirements:

✑ The data center core switch must be connected to one of the leaf switches with a single 1G link.

✑ The routes must be exchanged using a link-state routing protocol that supports hierarchical network design.

✑ The data center core switch interface must be using 802.1Q tagging, and each vlan will be configured with a dedicated IP address.

Which set of steps accomplishes these goals?
A . Set up the ElGRP Protocol policy with the selected Autonomous System number. Set up the Routed External Network object ana Node Profile, selecting ElGRP Create the Switch profile, selecting Port-channel and the appropriate interfaces Create the default network and associate it with the Routed Outside object.
B . Set up the BGP Protocol policy with the Autonomous System number of 0.
Configure an interface policy and an External Bridged Domain.
Create an External Bridged Network using the configured VLAN pool.
Build the Leaf profile, selecting Routed sub-interface and the appropriate VLA
D . Configure the OSPF Protocol policy with an area of 0.
Create Routed Outside object and Node Profile, selecting OSPF as the routing protocol.
Build the Interface profile, selecting Routed Sub-interface and the appropriate VLA
E . Configure the External Network object with a network of 0.0.0.0/0.
F . Set up the ElGRP Protocol policy with the selected Autonomous System number. Create the Routed Outside object and Node Profile selecting ElGRP Configure the Interface profile selecting Routed Interface and the appropriate interfaces. Create the External Network object with a network of 0.0.0.0/0.
