CCNA (200-120) - Cisco Certified Network Associate

The CCNA is the world's most recognised entry networking certification, and this course prepares you for it properly. You'll learn IP addressing, configure routers and switches, understand routing and switching, and troubleshoot networks in hands-on labs. It's the launchpad for a well-paid networking career.

Duration: 2 Months
Format: Live 1-on-1
Level: Professional
Certificate: Osian NSDC

Overview

What this course is about

Reliable networks begin with understanding how devices communicate, not with memorising command lists. CCNA 200-120 live 1-on-1 online classes cover IPv4 and IPv6 addressing, Ethernet, switching, routing, wireless basics and network troubleshooting. The teacher uses diagrams, packet flow and guided configuration so you can connect theory with the behaviour of a real network. This CCNA course online is suited to Indian students, IT support beginners and professionals moving towards infrastructure work.

Practical labs introduce VLANs, trunking, inter-VLAN routing, static routes, OSPF concepts, DHCP, NAT, access control lists and basic device security. You will interpret a topology, calculate subnets, read show commands and isolate a connectivity fault step by step. Cisco Packet Tracer or an available lab environment can be used for repeatable practice. Documentation, addressing tables and clear change notes are included because good network work must be understood by the next person.

The listed 200-120 label is treated as a study reference, not as a claim about a current Cisco exam code. Cisco exam objectives and names can change, so verify the latest official outline before registering. This is an associate-level networking foundation, while CCNP goes deeper into professional routing, switching and enterprise design. Academy support includes a completion certificate, resume help, mock interviews and placement assistance with flexible personal timings.

Questions

Before you enrol

Exam codes and Cisco objectives can be revised, so the reference should be checked against Cisco's current official certification page. The learning covers durable associate-level networking concepts and the teacher can map study to the latest outline.

No, Packet Tracer is suitable for many introductory topologies and command exercises. If you have authorised access to physical or virtual equipment, the same concepts can be extended with careful configuration practice.

You practise prefix notation, usable ranges, host planning and troubleshooting address mistakes. Subnetting is taught with worked networks and repetition, not left as a single formula to memorise.

Yes, the course introduces wireless concepts, device hardening, passwords, management access and basic access control lists. It keeps the treatment appropriate for an associate foundation rather than claiming expert security depth.

CCNA establishes core connectivity, switching, routing, addressing and troubleshooting skills. CCNP assumes that foundation and moves towards deeper enterprise routing, advanced services and professional-level design or implementation.

The course prepares you for Cisco-related concepts and study, but any official Cisco exam registration, fee and certification follow Cisco's own process. You receive academy learning support and a completion certificate for the training.
