What is the default behavior of the T1 timer in DHCP renewal?

Rebind with any DHCP server
Release the current IP address
Check in with the DHCP server to renew the IP address
Wait for additional server responses

The correct answer is: Check in with the DHCP server to renew the IP address

The default behavior of the T1 timer in DHCP renewal is to check in with the DHCP server to renew the IP address. Upon obtaining an IP address through the DHCP lease process, the client device will begin counting down the T1 timer, which is typically set to 50% of the lease duration. Once this timer reaches its expiration, the client attempts to renew its lease with the original DHCP server from which it obtained the IP address. This renewal process is critical for maintaining the client’s currently assigned IP address and ensuring ongoing network connectivity. If the DHCP server successfully responds to the renewal request, the lease is extended, allowing the client to continue using the same IP address without disruption. This proactive approach helps in minimizing conflicts and ensures efficient management of IP addresses within the network. In contrast, other options focus on alternatives that occur either after the T1 timer has expired or involve different behaviors related to DHCP lease management.
