Refer to the exhibit. Which two options must be configured on the Layer 3 Gateway switches to isolate the HSRP between the two data centers? (Choose two.)
A.
routed access control list on the DCI on the SVIs that blocks the HSRP control traffic.
B.
VLAN access control list that blocks the HSRP control traffic.
C.
ARP inspection filter that blocks the HSRP GARPs
D.
disable HSRP GARP on the SVIs for the VLANs that move across the DCI
E.
port access control list on the DCI port-channel that blocks the HSRP control traffic BC
The answer is perfectly defined as DE here:
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/interfaces/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_Interfaces_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_Interfaces_Configuration_Guide_7x_appendix_01110.html
In this example, the Layer 3 (L3) gateway is configured on the same vPC pair and acts as the DCI. In order to isolate the Hot Standby Routing Protocol (HSRP), you must configure a Port Access Control List (PACL) on the DCI port-channel and disable HSRP Gratuitous Address Resolution Protocols (ARPs) (GARPs) on the Switched Virtual Interfaces (SVIs) for the VLANs that move across the DCI.
I think, B+C are correct.
