A FreeBSD workstation has a stale DHCP lease and needs to obtain a fresh IP address from the DHCP server. Which sequence of commands accomplishes this?

ifconfig em0 down && ifconfig em0 up

killall dhclient && dhclient em0

dhclient em0 && dhclient -r em0

What is an interface alias in BSD networking?

An additional IP address assigned to the same physical interface.

A symbolic name for a network interface.

A virtual interface created for VPN connections.

A secondary network interface used for backup.

A FreeBSD server hosts multiple websites, each with its own IP address, on the same physical NIC (em0). The administrator needs to add a second IP address that persists across reboots. Which configuration is correct?

Run 'ifconfig em0 inet 192.0.2.11 netmask 255.255.255.0'

Add 'ifconfig_em0="inet 192.0.2.10 netmask 255.255.255.0 inet 192.0.2.11 netmask 255.255.255.0"' to /etc/rc.conf

Create /etc/ifconfig.em0 with 'inet 192.0.2.11 netmask 255.255.255.0'

Add 'ifconfig_em0_alias0="inet 192.0.2.11 netmask 255.255.255.0"' to /etc/rc.conf

What is the main purpose of DHCPv6?

To provide stateful configuration for IPv6 hosts, including address assignment and other options.

To provide stateless autoconfiguration of IPv6 addresses.
