Question 1

What is 3-tier design model?

Answer 1

Core, Distribution, Access

Question 2

What is 2-tier design model?

Answer 2

Collapsed Core/Distribution, Access

Question 3

What is Collision Domain?

Answer 3

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

Question 4

What is Broadcast Domain?

Answer 4

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

Question 5

What are three [3] Form Factors?

Answer 5

1. Fixed Configuration Switches
2. Modular Configuration Switches
3. Stackable Configuration Switches

Question 6

What is Converged Network?

Answer 6

Many types of traffic converge to one network?

Question 7

What are two [2] switch forwarding?

Answer 7

1. Store and Forward

2. Cut through

Question 8

What is Store and forward

Answer 8

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

Question 9

What is cut through switch?

Answer 9

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.

Question 10

What is a MAC address table?

Answer 10

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

Question 11

What is a native Vlan

Answer 11

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

Question 12

What is a management Vlan?

Answer 12

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

Question 13

What is a Vlan Trunk?

Answer 13

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.

Question 14

What is Inter-VLAN Routing?

Answer 14

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.

Question 15

What is Link aggregation?

Answer 15

Link aggregation is the ability to create one logical link using multiple physical links between two devices

Question 16

What is PAgP?

Answer 16

Port Aggregation Protocol

Question 17

What is LACP

Answer 17

Link Aggregation Control Protocol

Question 18

What does PAgP (Port Aggregation Protocol) do?

Answer 18

Cisco-proprietary protocol will create and manage etherchannel links

Question 19

What does LACP (Link Aggregation Control Protocol) ?

Answer 19

None Cisco-proprietary protocol will create and manage etherchannel links

Question 20

What is switching loops?

Answer 20

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).

Question 21

What is the speed and frequency for 802.11

Answer 21

2MB/s and 2.4GHz

Question 22

What is the speed and frequency for 802.11a

Answer 22

54 MB/s and 5GHz

Question 23

What is the speed and frequency for 802.11b

Answer 23

11 MB/s and 2.4GHz

Question 24

What is the speed and frequency for 802.11g

Answer 24

54 MB/s and 2.4GHz backward compatible 802.11b

Question 25

What is the speed and frequency for 802.11n

Answer 25

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

Question 26

What is the speed and frequency for 802.11ac

Answer 26

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

Question 27

What is the speed and frequency for 802.11ad

Answer 27

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

Question 28

What is SVI stand for?

Answer 28

Switch Virtual Interface

Question 29

What does RSTP stand for?

Answer 29

Rapid Spanning Tree Protocol

Question 30

What does RSTP (Rapid Spanning Tree Protocol)

Answer 30

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

Question 31

What are three [3] Management Field

Answer 31

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

Question 32

What is DTP mean?

Answer 32

Dynamic Trunking Protocol (DTP)

Question 33

What does Dynamic Trunking Protocol (DTP) do ?

Answer 33

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.

Question 34

What are PAgP modes

Answer 34

On, Desirable, Auto

Question 35

What does PAgP setting “on” do?

Answer 35

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

Question 36

What does PAgP setting “Desirable” do?

Answer 36

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

Question 37

What does PAgP setting “Auto” do?

Answer 37

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.
