   What is MP-BGP used for in Cisco ACI fabric?

   • AMP-BGP VPNv4 AF is used as protocol on L3Out between a border leaf and an external router
   • BMP-BGP Layer 2 VPN EVPN AF is used to propagate L3Out routes that are received from a border leaf
   • CMP-BGP VPNv4 AF is used to propagate L3Out routes that are received from a border leaf to the fabric
   • DMP-BGP VPNv4 AF is used between spines in an ACI Multi-Pod fabric to propagate the endpoint

   What are two descriptions of ACI Multi-Site? (Choose two.)

   • ARouters in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP
   • BACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites
   • CThe Multi-Site orchestrator must be directly attached to one ACI leaf
   • DACI Multi-Site is a solution that supports a dedicated APIC cluster per site
   • EThe Inter-Site network routers should run OSPF to establish peering with the spines

   A Cisco ACI is integrated with a VMware vSphere environment. The port groups must be created automatically in vSphere and propagated to hypervisors when created in the ACI environment. Which action accomplishes this goal?

   • ACreate the port groups on the vCenter that reflect the EPG names in the APIC
   • BAssign the uplinks of the ESXi hosts to the vDS that the APIC created
   • CConfigure contracts for the EPGs that are required on the ESXi hosts
   • DAssociate the VMM domain with the EPGs that must be available in vCenter

   A network engineer is integrating a new Hyperflex storage duster into an existing Cisco ACI fabric. The Hyperflex cluster must be managed by vCenter, so a new vSphere Distributed switch must be created. In addition, the hardware discovery must be performed by a vendor-neutral discovery protocol. Which set of steps meets these requirements?

   • AConfigure an Interface Policy group, select CDP, and apply it to the desired interfaces. Enter the vCenter IP and credentials in the Create vCenter Controller dialog box. In the Create VMware VMM domain dialog box, select Read-Only Mode.
   • BConfigure an Interface Policy group, select LLDP, and apply it to the selected interfaces. Create a VLAN pool, add it to the VMware VMM domain, and include the appropriate interfaces. Enter the vCenter IP and credentials in the Create vCenter Controller dialog box.
   • CConfigure a Switch Policy group, select LLDP, and apply it to the indicated interfaces. Set up a VMware VMM domain and apply it to the appropriate interfaces. Enter the APIC management IP and credentials in the Create vCenter Controller dialog box.
   • DConfigure an Interface Policy group, select CDP, and apply it to the designated interfaces. Create a VMware VMM domain, add it to the VLAN pool, and associate it to the designated interfaces. Select Read Only Mode in the Create VMware VMM domain dialog box.
