C. Configure a taboo contract and apply it to the EPG.

D. Configure the EPG as a consumer and L3 out as a provider of the contract.

An engineer must configure VMM domain integration on a Cisco UCS B-Series server that is connected to a Cisco ACI fabric. Drag and drop the products used to create VMM domain from the bottom into the sequence in which they should be implemented at the top. Products are used more than once.

Refer to the exhibit. How are the STP BPDUs forwarded over Cisco ACI fabric?

A. Cisco ACI acts as the STP root for all three external switches.

Refer to the exhibit. A client is configuring a new Cisco ACI fabric. All VLANs will be extended during the migration phase using the VPC connections on leaf switches 3. 4 and leaf switches toward the legacy network. The migration phase has these requirements;

* If The legacy switches must be able to transfer BPDUs through the ACI fabric.

* If the legacy switches fail to break a loop. Cisco ACI must break the loop.

BPDU Filter: enabled

D. MCP: disabled
BPDU Guard: enabled
BPDU Filter enable

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 VLAN.

C. 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 VLAN.
Configure the External Network object with a network of 0.0.0.0/0.

D. 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.
