The DHCP Client will attempt to renew its lease after what percentage of the lease time has elapsed?

• A. 50%
• B. 25%
• C. 100%
• D. 75%

Answer: (A)

DHCP lease renewal is triggered at the halfway point of the lease duration. When a client obtains a lease, it tracks how long the lease lasts and, at halfway through that period, it sends a DHCPREQUEST to the server that granted the lease to renew it. If the renewal is accepted, the lease is extended and normal operation continues without interruption. If renewal fails, the client will move to the next phase, attempting to rebind later (closer to the end of the lease) by broadcasting to any available DHCP server. This approach keeps the IP address alive without waiting until the lease actually expires, while still ensuring the client has a chance to renew with the original server first. So the correct understanding is that renewal occurs at the halfway point of the lease time.
