A network administrator found that the IP device tracking table on a switch is not getting updated when the client has a static IP address, but if the address is from DHCP, the table is getting updated. Which description of the cause of this issue is true?
Correct Answer: C
If you don't have DAI enabled, IP device tracking can update it's database because it uses probes which are activated by default. If you do have DAI enabled (with DHCP Snooping of course), the DHCP Snooping DB will not be populated and DAI will deny the ARP Requests from that port, making ip device tracking DB unable to get the IP-MAC binding. Creating an ARP ACL and applying it to DAI solves this problem and populates the ip device tracking table as well.
