2. TRAINING TECHNOLOGY: CCNA
CCNA: CISCO CERTIFIED NETWORK ASSOCIATE
The CCNA certification was the first course and exam in the Cisco
certification process, and the precursor to all current Cisco
certifications. Cisco is the king of routing, switching, and security, the
Microsoft of the internetworking world.
The Cisco certifications reach beyond the popular certifications, such
as the CompTIA and Microsoft certifications, to provide us an
indispensable factor in understanding today’s network— insight into the
Cisco world of internetworking.
3. Routing
• Static Routing:
Static routing is when you statically configure a router to
send traffic for particular destinations in preconfigured
directions.
• Dynamic Routing:
Dynamic routing is when you use a routing protocol such
as OSPF, ISIS, EIGRP, and/or BGP to figure out what paths
traffic should take.

5. Switching
Q. WHAT IS A SWITCH ?
Ans. Most business networks today use switches
to connect computers, printers and servers within
a building or campus. A switch serves as a
controller, enabling networked devices to talk to
each other efficiently. Through information sharing
and resource allocation, switches save businesses
money and increase employee productivity.
6. ROLES OF SWITCH
• Store and Forward: The switch stores and verifies each
packet before routing it.
• Cut through: The switch verifies the portion of the packet
header up to the hardware address of frame before it is
forwarded. They may have to stick to the store and
forward procedure if the outgoing port is engaged when
the packet enters.
• Adaptive switching: This method automatically selects
one of the above two methods depending upon traffic
situation.
7. CAN – Campus Area Network
Q. WHAT IS CAN?
Ans. A campus network, campus area network,
corporate area network or CAN is a
computer network made up of an interconnection of
local area networks (LANs) within a limited
geographical area.
