Q

Spine and leaf topology is designed how …?

A

Two Tier - typically used in Data Center Design

Core/Distribution (Spine)
L2/L3 switch that perform both routing and switching.

Q

Hybrid topology by design relates to the use of …?

A

physical and logical connects are used

ex. Ethernet cable (Physical) Logical (IP Address)

Q

In a fully meshed topology the formula to calculate number of connection needed?

A

C=n (n-1) /2

C = # of connections
n = # of devices

ex. For 6 devices C=6(6-1)/2=15

(6-1) = 5 x 6 = 30 / 2 = 15
