Subnetting for Cisco Certification Exams

Solve any Subnetting question in less than 30 seconds and get certified easily.

Subnetting is an absolutely critical component for CCNA success. In this videos, we are first going to review how subnetting works, ensure you master the “30 sec” method and understand the mathematics behind this networking principle. Once this is done, we are going to look at some shortcuts (tips) that can be used in the exam to ensure that we can solve the many subnetting challenges quickly and accurately (30 sec).

Computers participating in a network such as the Internet each have at least one network address. Usually, this address is unique to each device and can either be configured automatically with the Dynamic Host Configuration Protocol (DHCP) by a network server, manually by an administrator, or automatically by stateless address autoconfiguration.

An address fulfills the functions of identifying the host and locating it on the network. The most common network addressing architecture is Internet Protocol version 4 (IPv4), but its successor, IPv6, has been increasingly deployed since approximately 2006. An IPv4 address consists of 32 bits, for readability written in a form consisting of four decimal octets separated by dots, called dot-decimal notation. An IPv6 address consists of 128 bits written in hexadecimal notation and groupings of 16 bits, called hextets, separated by colons. An IP address is divided into two logical parts, the network prefix and the host identifier. All hosts on a subnetwork have the same network prefix. This prefix occupies the most-significant bits of the address. The number of bits allocated within a network to the prefix may vary between subnets, depending on the network architecture. The host identifier is a unique local identification and is either a host number on the local network or an interface identifier.

Subnetting is an absolutely critical component for CCNA success.

It is wonderful to see how all of this works 30 sec, but in the lab exam environment, we are VERY pressed for time. We need powerful shortcuts. Here we will walk through my preferred shortcuts against the backdrop of sample exam questions.
