Solution:-
---------------------------------------------------------------------------------------------------
Answer 22
The correct answer is option (d) NFPA
NFPA stands for National fire protection association which developed the national electrical code.
---------------------------------------------------------------------------------------------------
Answer 23
The correct answer is option (c) Coaxial
The coaxial cable less used compare to UTP, STP and Fiber. Mostly network cabling coaxial cable is replaced by UTP and Fiber.
---------------------------------------------------------------------------------------------------
Answer 24
The correct answer is option (b) follow local building codes
This option is not related to the cable installation quality considerations.
---------------------------------------------------------------------------------------------------
Answer 25
The correct answer is option (b) 4
There are 4 pairs in UTP cable. Total 8 cables are twisted in a color coding.
---------------------------------------------------------------------------------------------------
Answer 26
The correct answer is option (c) Crossover
The crossover cable is used to connect directly two same equipments.
---------------------------------------------------------------------------------------------------
Answer 27
The correct answer is option (c) Hub
To create a star topology Hub can be used. It simply connects the PC's of a network and it is placed in the center.
---------------------------------------------------------------------------------------------------
Answer 28
The correct answer is option (b) Network interface card
NIC is stands for network interface card or network interface controller.
---------------------------------------------------------------------------------------------------
Answer 29
The correct answer is option (c) to increase LAN performance
The hub simply connects the end systems and distribute the link bandwidth to equally to all. Switch overcome this problem and creates a virtual circuit between source and destination and let them use dedicated bandwidth so LAN performance is increased.
---------------------------------------------------------------------------------------------------
Answer 30
The correct answer is option (d) IPX
IPX is not used at MAC layer, it is a network layer protocol. So IPX is not a MAC layer protocol.
