What is Collision Domain?

A collision domain is a section of a network where data packets can collide with one another when being sent on a shared medium or through repeaters, particularly when using early versions of Ethernet

What is Broadcast Domain?

Any computer connected to the same Ethernet repeater or switch is a member of the same broadcast domain

What is Store and forward

Will look the entire frame and then it will forward if it is valid

What is cut through switch?

looked up the destination MAC address of the frame in its MAC address table. The switch does not have to wait for the rest of the frame to enter the ingress port before making its forwarding decision.

What is a MAC address table?

A MAC address table is a table that stores MAC address and forward through individual port rather than flooding the all ports

What is a native Vlan

A native VLAN is assigned to an 802.1Q trunk port. Trunk ports are the links between switches that support the transmission of traffic associated with more than one VLAN

What is a management Vlan?

A management VLAN is any VLAN configured to access the management capabilities of a switch. VLAN 1 is the management VLAN by default.

What is a Vlan Trunk?

A VLAN trunk, or trunk, is a point-to-point link between two network devices that carries more than one VLAN. A VLAN trunk extends VLANs across an entire network. Cisco supports IEEE 802.1Q for coordinating trunks on Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces.

What is Inter-VLAN Routing?

Inter-Vlan Routing is the capability to route traffic between vlans. This functionality could be on the Switch itself (for Layer 3 Switches), on another module or card on the switch (for modular switches) or even an external router.

What is PAgP?

Port Aggregation Protocol

What is LACP

Link Aggregation Control Protocol

What does PAgP (Port Aggregation Protocol) do?

Cisco-proprietary protocol will create and manage etherchannel links

What does LACP (Link Aggregation Control Protocol) ?

None Cisco-proprietary protocol will create and manage etherchannel links

What is switching loops?

A Switching loop or Bridge loop occurs in computer networks when there is more than one Layer 2 (OSI model) path between two endpoints (e.g. multiple connections between two network switches or two ports on the same switch connected to each other).

What is the speed and frequency for 802.11

2MB/s and 2.4GHz

What is the speed and frequency for 802.11a

54 MB/s and 5GHz

What is the speed and frequency for 802.11b

11 MB/s and 2.4GHz

What is the speed and frequency for 802.11g

54 MB/s and 2.4GHz backward compatible 802.11b

What is the speed and frequency for 802.11n

600 MB/s and 2.4GHz and 5GHz backward compatible 802.11a/b/g

What is the speed and frequency for 802.11ac

1.3 GB/s (1300 MB/s) and 5 GHz backward compatible 802.11a/n

What is the speed and frequency for 802.11ad

7 GB/s (7000 MB/s) 2.4 GHz and 5 GHz and 60GHz backward compatible 802.11a/b/g/n/ac

What is SVI stand for?

Switch Virtual Interface

What does RSTP stand for?

Rapid Spanning Tree Protocol

What does RSTP (Rapid Spanning Tree Protocol)

The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails, without the danger of bridge loops, or the need for manual enabling/disabling of these backup links

What are three [3] Management Field

1. Header 2. Payload 3. FCS (frame check sequence)

What is DTP mean?

Dynamic Trunking Protocol (DTP)

What does Dynamic Trunking Protocol (DTP) do ?

If a port can become a trunk, it may also have the ability to trunk automatically, and in some cases even negotiate what type of trunking to use on the port. DTP provides this ability to negotiate the trunking method with the other device.

What are PAgP modes

On, Desirable, Auto

What does PAgP setting "on" do?

The "on" mode forces the interface to channel without PAgP. Interfaces configured in the this mode do not exchange PAgP packets.

What does PAgP setting "Desirable" do?

The "on" mode places an interface in an active negotiating state in which the interface initiates negotiations with other interfaces by sending PAgP packets.

What does PAgP setting "Auto" do?

The "Auto" mode places an interface in a passive negotiating state in which the interface responds to the PAgP packets that it receives, but does not initiate PAgP negotiation.
