During a review, the administrator for Harborview Logistics is asked to troubleshoot DAI dropping valid static-IP devices that lack DHCP bindings. Which approach satisfies the precise requirement?
Explanation
Correct Answer
DAI needs a trusted IP/MAC association for hosts without DHCP-snooping entries. This is the control that implements the specified requirement.
Incorrect Answers
TCP port 23 identifies Telnet, while SSH normally uses TCP port 22. That is not sufficient here: DAI needs a trusted IP/MAC association for hosts without DHCP-snooping entries.
Segmentation limits lateral movement paths through network boundaries. That is not sufficient here: DAI needs a trusted IP/MAC association for hosts without DHCP-snooping entries.
Scanning probes service exposure and can be an early indicator of attempted intrusion. That is not sufficient here: DAI needs a trusted IP/MAC association for hosts without DHCP-snooping entries.
