A network administrator wants to have the same network mask for all networks at a particular small site. The site has the following networks and number of devices:

The network administrator has deemed that 192.168.10.0/24 is to be the network used at this site. Which single subnet mask would make the most efficient use of the available addresses to use for the four subnetworks?

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).

Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?

What characteristic describes antispyware?

A network administrator wants to have the same subnet mask for three subnetworks at a small site. The site has the following networks and numbers of devices:

Subnetwork A: IP phones – 10 addresses
Subnetwork B: PCs – 8 addresses
Subnetwork C: Printers – 2 addresses
What single subnet mask would be appropriate to use for the three subnetworks?

Which two traffic types use the Real-Time Transport Protocol (RTP)? (Choose two.)

Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

Which two statements describe features of an IPv4 routing table on a router? (Choose two.)
