  • A Modify the subnet mask to the network 192.168.1.0 255.255.254.0 command in the DHCP pool
  • B Configure the DHCP lease time to a smaller value
  • C Configure the DHCP lease time to a bigger value
  • D Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool
Explanation

The 192.168.1.0/24 pool has only 205 usable, nonexcluded DHCP addresses available, while about 300 users may need leases. A 12-day lease retains addresses for far longer than the users’ maximum two-hour daily activity, so the pool can become exhausted. Configuring a shorter lease duration releases unused addresses sooner for reassignment.
