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.)
The issue described suggests a problem with ARP spoofing, where invalid MAC addresses are causing connectivity issues. To mitigate ARP spoofing, 'arp inspection untrusted' should be enabled on the end-user's physical ports to ensure that only legitimate ARP replies are accepted. Additionally, enabling 'arp inspection' on the end-user VLAN will help validate ARP packets in that VLAN, preventing invalid MAC address assignments. These measures will ensure that only valid ARP responses from trusted devices are allowed and help resolve the connectivity issues.
My answer is A & C.
