Question 16 of 20

16. Question
Alex has been hired to connect three local area networks (LANs) with redundant paths, forming a fault-tolerant backbone. The LANs reside on diﬀerent floors in the same building and are approximately 600 meters apart. Each LAN is currently configured in a star/hub and spoke topology using twisted-pair cabling. Each LAN includes wall plates and rack-mounted patch panels and switches. Building and fire codes allow cables to run through existing risers, ceilings, and walls, but a 50,000-watt radio station occupies one of the floors between the LANs. Which topology, cable type, and installation method best suits this network?
- A.Star/hub and spoke topology, fiber-optic cabling, and internal installation.
- B.Star/hub and spoke topology, coaxial cabling, and external installation
- C.Mesh topology, fiber-optic cabling, and external installation
- D.Bus topology, twisted-pair cabling, and internal installation
- E.Mesh topology, fiber-optic cabling, and internal installation
Correct

Correct

Incorrect
Question 18 of 20

18. Question
Which of the following best describes the diﬀerence between east-west and north-south traﬃc in a data center?
- A.East-west describes traﬃc between devices at the same OSI model layer, while north-south describes traﬃc between OSI model layers.
