  1. An exclusion
  2. A lease
  3. A reservation ✔

Why: A reservation ties an address to one DHCP client, so the device always gets the same IP. An exclusion keeps addresses out of the pool, and a lease is the time an address can be used.

Huh, didn't know that: Microsoft notes that unused leased addresses automatically return to the pool for reallocation.
