You have a small network as shown in the Exhibit.
You configure DHCP on Router1 to provide IP addresses to all hosts connected to
SwitchA. Following the configuration, you verify that Wrk1 has received an IP address
from the DHCP service. Wrk1 can ping every host on the subnet, but cannot
communicate with any hosts connected to Switch B or on the Internet.
What should you do? - answer Configure the DHCP server to deliver the default
gateway address along with the IP address.

,Router1 will provide NAT services to all hosts on the private network, and DHCP
services to hosts connected to SubnetA.
Srv1 is located on SubnetA. You want to make sure that this server is assigned the
same IP address every time it boots, but you still want to centrally manage the address
that it uses.
What should you do? - answer Configure a DHCP binding for Srv1.
You want to configure DHCP on your Cisco router to provide automatic IP address
assignment to a single subnet. You will use 192.168.12.0/27 for the subnet address.
The router interface has been configured with an IP address of 192.168.12.1.
Additionally, you want to make sure that a specific server, called SrvFS, always gets the
last IP address on the subnet as its IP address.
How should you configure DHCP on the router? (Select two.) - answer * Create a
DHCP binding for address 192.168.12.30
* Create an address pool with start address of 192.168.12.2 and end address
192.168.12.30
