A customer with an ArubaOS-CX 6300M switch is having a performance issue on the network and has received complaints about users experiencing intermittent connectivity. After performing troubleshooting, it is determined that many of the local websites on the LAN that users are unable to reach are resolved to an invalid MAC address.
What are the minimum steps that should be performed to mitigate this condition? (Choose two.)
To address the issue described, implementing ARP ACLs to define trusted MAC address to IP bindings ensures that only legitimate MAC addresses can be associated with specific IP addresses, preventing resolution to invalid MAC addresses. Additionally, enabling 'arp inspection' on the end-user VLAN helps monitor and validate ARP packets in the VLAN, ensuring ARP requests and responses are correct and thus mitigating the problem of invalid MAC addresses being resolved.
My answers are B & C. Question is not so clear and it maybe release related. DHCP Snooping is a must for a working ARP inspection under vlan level. You need to declare truste interface, not untrusted.
