30s - Q11
Routing data between computers on a network requires several mappings between different addresses. Which of the following statements is true?
Diskless workstations use ARP to ask a server for an IP address.
Hosts use ARP to resolve known IP addresses into MAC addresses.
ICMP lets routers bypass the general network broadcast by providing a dynamic table of IP-to-MAC address mappings.
Routers use DNS to resolve MAC addresses of diskless workstations into IP addresses based on the information contained in other routers' routing tables.
30s - Q12
