Public

Question 14

____ IP addresses are basically used for host computers that require IP connectivity, but do not need to be visible on the public network.

Question 18

____ is a methodology of allocating IP addresses and routing Internet Protocol packets. IP addresses are described as consisting of two groups of bits in the address: the most significant part is the network address which identifies a whole network or subnet and the least significant portion is the host identifier, which specifies a particular host interface on that network.

Answer 18

Classless Inter-Domain Routing (CIDR)

Question 19

Answer 23

MAC

Question 24

Unlike other addresses,____ addresses are absolute- a ____ address on a host normally doesn’t change as long as the NIC doesn’t change

Answer 24

MAC

Question 25

A ____contains six octets in which the first three octets are referred to as Organizationally Unique Identifier (OUI), and the last three octets are referred to as Network Interface Controller (NIC) Specific Identifier.

MAC

Question 27

____is a process through which an IP address network is divided into smaller networks. It is a hierarchical partitioning of the network address space of an organization into several ____. ____ creates smaller broadcast domains. It helps in the better utilization of the bits in the Host ID. To subnet a network, you take some bits from the host ID and give them to the network ID. As the manager and designer of a network, you have the freedom to do this.

Answer 27

Subnetting
