Refer to the exhibit.The enterprise has decided to use the network address 172.16.0.0. The network administrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40 and 50 hosts, as shown. What subnet mask would accommodate this network?
A. 255.255.255.192 B. 255.255.255.224 C. 255.255.255.240 D. 255.255.255.248 E. 255.255.255.252 |

The network manager has requested a 300-workstation expansion of the network. The workstations are to be installed in a single broadcast domain, but each workstation must have its own collision domain. The expansion is to be as cost-effective as possible while still meeting the requirements. Which three items will adequately fulfill the request? (Choose three).
A. one IP subnet with a mask of 255.255.254.0 B. two IP subnets with a mask of 255.255.255.0 C. seven 48-port hubs D. seven 48-port switches E. one router interface F. seven router interfaces |
ADE

--300 host need 9 bits host section
--Workstation must have its own collision domain means need to use switch not hub --Single broadcast domain means need only one router |
|
|
What is the purpose of assigning an IP address to a switch?
A. provides local hosts with a default gateway address B. allows remote management of the switch C. allows the switch to respond to ARP requests between two hosts D. ensures that hosts on the same LAN can communicate with each other |
