NET-06-P1 Subnetting Concepts

Question 1

means subdividing a network to manage, design and implement an effective IP addressing plan. Reduces overall network traffic and improves performance

Answer 1

Subnetting

Question 2

containing many hosts poses a problem for broadcast domains, because hosts can generate broadcast messages and affect network performance

Answer 2

Large Broadcast Domains

Question 3

is a subnet created by borrowing one or more of the host bits to be used as network bits

e.g: Additional 1 bits means more Networks
Additional 0 bits means more Hosts

Answer 3

Octet Boundary*

Question 4

allows an IP address to use any subnet mask, regardless of predefined classes

Answer 4

Classless Inter-domain Routing

Question 5

Why would organizations uses a Classless Interdomain Routing

Answer 5

Some organizations with big networks (400 hosts) must use class B, which means they will waste addresses (60,000)

Question 6

is a method by which a network is subnetted are then subnetted further

Answer 6

VLSM - Variable Length subnet mask

Question 7

How many hosts are in a Class C network

Answer 7

254

Question 8

How many hosts are in a Class B network

Answer 8

65,534

Question 9

How many hosts are in a Class A network

Answer 9

16,777,214
