2. True or false: You can use DHCP to specify the TFTP hosts IP address to a client PC.

3. True or false: 255.255.255.248 and /28 are two representations of the same IP mask.

4. True or false: Upper-layer protocols are identified in the IP headers protocol field. TCP is protocol 6, and UDP is protocol 17.
