Is historic lease history always available by default?

• A. Yes, historic lease history is always available.
• B. No, it must be enabled via Lease History or Reporting Server.
• C. Only for IPv6 leases.
• D. Only when a client is currently connected.

Answer: (B)

Historic lease history is not available by default. To retain and access past DHCP lease events, you must enable the feature, either through Lease History or via a Reporting Server. When enabled, the system records lease lifecycle changes (such as when a lease is issued, renewed, released, or expired) so you can audit or report on which device had which address at a given time. Without enabling it, only the current lease state is kept and historical data aren’t stored. This capability isn’t limited to IPv6 and isn’t dependent on the client being connected, so those options don’t apply.
