Refer to the exhibit. The network administrator has assigned the LAN of LBMISS an address range of 192.168.10.0. This address range has been subnetted using a /29 prefix. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network (subnet zero is the first subnet). By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?

IP phones – 22 addresses
PCs – 20 addresses needed
Printers – 2 addresses needed

A network administrator needs to monitor network traffic to and from servers in a data center. Which features of an IP addressing scheme should be applied to these devices?

random static addresses to improve security
addresses from different subnets for redundancy
predictable static IP addresses for easier identification
dynamic addresses to reduce the probability of duplicate addresses

16. Question

Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)

It eliminates most address configuration errors.
It ensures that addresses are only applied to devices that require a permanent address.
It guarantees that every device that needs an address will get one.
It provides an address only to devices that are authorized to be connected to the network.
It reduces the burden on network support staff.

17. Question

A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24.

18. Question

Refer to the exhibit. A company is deploying an IPv6 addressing scheme for its network. The company design document indicates that the subnet portion of the IPv6 addresses is used for the new hierarchical network design, with the site subsection to represent multiple geographical sites of the company, the sub-site section to represent multiple campuses at each site, and the subnet section to indicate each network segment separated by routers. With such a scheme, what is the maximum number of subnets achieved per sub-site?
