A malicious user gained network access by spoofing printer connections that were authorized using MAB on four different switch ports at the same time.What two catalyst switch security features will prevent further violations? (Choose two)
Answer(s): A,E
Which command enables 802.1X globally on a Cisco switch?
Answer(s): A
Which RADIUS attribute can you use to filter MAB requests in an 802.1 x deployment?
Answer(s): C
Because MAB uses the MAC address as a username and password, you should make sure that the RADIUS server can differentiate MAB requests from other types of requests for network access. This precaution will prevent other clients from attempting to use a MAC address as a valid credential.Cisco switches uniquely identify MAB requests by setting Attribute 6 (Service-Type) to 10 (Call-Check) in a MAB Access- Request message. Therefore, you can use Attribute 6 to filter MAB requests at the RADIUS server.

A network administrator configures Dynamic ARP Inspection on a switch. After Dynamic ARP Inspection is applied, all users on that switch are unable to communicate with any destination. The network administrator checks the interface status of all interfaces, and there is no err-disabled interface.What is causing this problem?
Answer(s): D
Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.
