Question 79/132
After the administrator performs the configuration shown in the figure on a router, which of the following commands can be used to specify a short lease for addresses assigned using DHCP?
Correct Answer: C
The command lease day 0 hour 10 sets the lease time for DHCP-assigned IP addresses to 10 hours. This setting provides a short, specific lease duration for dynamically assigned IP addresses, which can be useful in networks where devices frequently join and leave, minimizing IP address retention time.
