Detailed Explanation:Stateless Address Autoconfiguration (SLAAC) allows IPv6 hosts to generate their own IP addresses but does not include DNS server information. DHCPv6 is typically required for DNS configuration. (Reference: HCIA-Datacom Training Material, IPv6 SLAAC and DNS)

The command lease day 0 hour 10 sets the lease time for DHCP-assigned IP addresses to 10 hours. This setting provides a short, specific lease duration for dynamically assigned IP addresses, which can be useful in networks where devices frequently join and leave, minimizing IP address retention time​.

In STP, a port moves from Learning to Forwarding state after the Forward Delay timer has expired. This delay ensures stability by allowing time for the topology to converge before the port begins forwarding user traffic, thereby preventing loops in the network during the transition​.

In a many-to-many non-NAPT (Network Address Port Translation) configuration, each private host requires a unique public IP address from the address pool. If only two public IP addresses are available and both are already in use by Host A and Host B, no IP will be available for Host C, preventing it from accessing the public network​.
