VCE
A Cisco ACI environment consists of multiple silent hosts that are often relocated between leaf switches. When the host is relocated, the bridge domain takes more than a few seconds to relearn the host's new location. The requirement is to minimize the relocation impact and make the ACI fabric relearn the new location of the host faster. Which action must be taken to meet these requirements?
A. Set Unicast Routing to Enabled.
B. Configure ARP Flooding to Enabled.
C. Set L2 Unknown Unicast to Hardware Proxy.
D. Configure IP Data-Plane Learning to No.
Refer to the exhibit.

A Cisco ACI fabric is created with L2Out to N7K1 and N7K2 switches. The switches are running MSTP with native VLAN 10. The N7K1 and N7K2 act as the root bridge for VLAN 20. An EPG named Data has been created. The ACI fabric must be configured with these requirements:
1.
The ACI fabric must receive MSTP BPDU.
2.
The N7K1 switch must act as the root bridge for VLAN 20.
Which set of actions accomplishes these goals?
A. Encapsulate EPG Data with VLAN 20. Set the VLAN mode to Trunk.
B. Encapsulate EPG Data with VLAN 10. Set the VLAN mode to Trunk.
C. Encapsulate EPG Data with VLAN 10. Set the VLAN mode to 802.1P.
D. Encapsulate EPG Data with VLAN 20. Set the VLAN mode to 802.1P.
An engineer wants to configure Cisco ACI switches to use authenticated ZMQ when communicating with the proxy spine.
Which configuration allows MD5 ZMQ messages only?
A. COOP Group policy in strict mode
B. IS-IS password using MD5
C. BGP password using MD5
D. COOP Group policy in compatible mode
