An engineer needs to deploy a leaf access port policy group in ACI Fabric to support the
following requirements:
• Control the amount of application data flowing into the system
• Allow the newly connected device to auto-negotiate link speed with the leaf switch
Which two ACI policies must be configured to achieve these requirements? (Choose two.)


A.

L2 interface policy


B.

link level policy


C.

slow drain policy


D.

ingress control plane policing policy


E.

ingress data plane policing policy





B.
  

link level policy



E.
  

ingress data plane policing policy





Slow Drain handles FCoE packets that are causing traffic congestion on ACI fabric. So, it is
wrong.
Ingress control plane is wrong, because the request is for “application data flowing”.
L2 interface policy is concerned about QinQ and VLAN scope.

Which method does the Cisco ACI fabric use to load-balance multidestination traffic?


A.

PIM routing


B.

spanning trees


C.

shortest-path trees


D.

forwarding tag trees





D.
  

forwarding tag trees

Which two statements regarding ACI Multi-Site are true? (Choose two.)


A.

The Multi-Site orchestrator must be directly attached to one ACI leaf.


B.

Routers in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP.


C.

ACI Multi-Site is a solution that supports a dedicated APIC cluster per site.


D.

ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites.


E.

The Inter-Site network routers should run OSPF to establish peering with the spines.

Regarding the MTU value of MP-BGP EVPN control plane packets in Cisco ACI, which
statement about communication between spine nodes in different sites is true?


A.

By default, spine nodes generate 9000-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9000-bytes packets.


B.

By default, spine nodes generate 1500-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 1800-bytes packets.


C.

By default, spine nodes generate 1500-bytes packets to exchange endpoints routing
information. As a result, the Inter-Site network should be able to carry 1500-bytes packets.


D.

By default, spine nodes generate 9000-bytes packets to exchange endpoints routing
information. As a result, the Inter-Site network should be able to carry 9100-bytes packets





D.

information. As a result, the Inter-Site network should be able to carry 9100-bytes packets
