Network Definition

Question 1

What is Attenuation?

Answer 1

The decrease in signal strength over distance in a wired network.

Question 2

What is Interference?

Answer 2

A signal degradation due to external sources.

Question 3

What is Latency?

Answer 3

The delay in time it takes for data to travel across the network.

Question 4

What is Congestion?

Answer 4

Occurs where there is excessive amount of traffic traversing a network segment, link, or device, leading to delays, packet loss, reduced throughput.

Question 5

What is Convergence?

Answer 5

• The process of all routers coming to agreement on optimal routes in a network.
• All routers learn the route to all connected networks

Question 6

What is Jitter?

Answer 6

• The difference in time it takes for packets to reach their destination.

Question 7

What is Route Poisoning?

Answer 7

A technique to prevent routers from sending packets through invalid routes.

Question 8

What is Split Horizon?

Answer 8

Prevents a route learned on one interface from being advertised
back out the same interface

Question 9

What is Ad Hoc Network?

Answer 9

Allow direct communication between devices without the need for a central infrastructure, making them ideal for temporary connections like file transfers between laptops.

Question 10

What is Infrastructure Network?

Answer 10

Require a central access point (such as a router or switch).

Question 11

What is channel bonding?

Answer 11

Creates a wider channel by merging two or more neighboring channels into a single wider channel are combined to increase throughput between two or more wireless devices.

Question 12

What is the common voltage at Data Center?

Answer 12

208 voltage

Question 13

What is best describe as Port Address Translation (PAT)?

Answer 13

A type of NAT where multiple private IP addresses are mapped to a single public IP address using different port numbers

Question 14

What is CrossTalk?

Answer 14

• An unintentional transmission (leakage) of a signal from one cable to another.
• Crosstalk can occur if the twisted pairs are not twisted sufficiently, because the twisting of the cable pairs reduces crosstalk between neighboring cable pairs.
