2. What's the difference between layer 3 switches and routers?

   learningnetwork.cisco.com/s/question/0D53i00000Kt6vQCAR

   Routers are used in the WAN environment. Router never forward broadcast traffic but switch does. The primary difference is with feature set support, hierarchical design and WAN interfaces. The purpose of layer 3 switches is aggregation and high speed packet forwarding between servers local to the data center.

   Only a few Layer-3 switch platforms in Cisco's portfolio support NAT, for example - this operation is relatively complex to perform in hardware. The same goes for tunneling, encryption, etc. So, from an end user's perspective, a Layer-3 switch is indistinguishable from a router - both have routing tables, both run routing protocols, both route ...

4. whats the difference between a switch, router and VLAN

   learningnetwork.cisco.com/s/question/0D53i00000KsqK4CAJ/whats-the-difference...

   A router moves IP packets between connected interfaces based on a lookup of the destination IP address in an IP packet against a routing information base (RIB or route table). A VLAN is a virtualized LAN segment. In other words, a switch without LAN virtualization bridges all of the ports together into a single layer 2 bridging domain.

5. What is the difference between switch and multiplexer?

   learningnetwork.cisco.com/s/question/0D53i00000KsnUeCAJ/what-is-the-difference...

   Tomas, Multiplexer sends multiple signals in parallel, while switches only send them in order. For example, a multiplexer can have a link to another multiplexer and it would receive multiple packets from PPP lines. Let's say it receives 10 packets from 10 different circuits every millisecond.

6. Difference between uplink and access (Downlink) port

   learningnetwork.cisco.com/s/question/0D53i00000Kt6XrCAJ/difference-between...

   Usually an uplink port connects to another switch, while an access port connects to a host. In some switches, such as some of the Nexus 9000 range, there are 4-6 40G ports, and 48 10G ports. In this case, the 40G ports are designated as uplink ports, and the rest are edge ports. Sometimes this is just used to explain the topology.

   What is the difference between router and L3 switching apart from WAN interfaces? L3 Switches have both routing and switching functionality where as routers only have routing functionalityOtherwise in case of L2 switches, if you make a VLAN, then you need a router. Apologies for the late response.
