(Jeremy's IT Day 2 Video) CCNA Interfaces and Cables

What does RJ stand for in RJ-45?

• Registered Jack

• Router Junction

• Remote Jumper

• Reinforced Jacket

What is the purpose of network protocols and standards?

• To enable communication between network devices

• To encrypt network data

• To increase network speed

• To prevent network interference

What is the difference between a straight-through cable and a crossover cable?

• A straight-through cable connects devices with the same transmit and receive pins, while a crossover cable reverses the transmit and receive pins

• A straight-through cable is used for wireless connections, while a crossover cable is used for wired connections

• A straight-through cable is used for connecting routers, while a crossover cable is used for connecting switches

• A straight-through cable is used for high-speed connections, while a crossover cable is used for low-speed connections

Which devices transmit data on pins 1 and 2, and receive data on pins 3 and 6?

• Routers and Firewalls

• PCs and Switches

• Switches and Firewalls

• Routers and PCs

What is the maximum cable length for twisted pair cables in Ethernet?

• 50 meters

• 100 meters

• 200 meters

• 500 meters

What is the purpose of Auto MDI-X in modern networking devices?

• To automatically detect and adjust the transmit and receive pins for communication

• To increase network speed

• To protect against electromagnetic interference

• To enable wireless connections

What is the difference between a bit and a byte?

• A bit is a value represented by 0 or 1, while a byte is a series of 8 bits

• A bit is a series of 8 bytes, while a byte is a value represented by 0 or 1

• A bit is a unit of speed, while a byte is a unit of data storage

• A bit is a unit of data storage, while a byte is a unit of speed

Which Ethernet standard uses all 8 wires in a UTP cable?

• 10BASE-T

• 100BASE-T

• 1000BASE-T

• 10GBASE-T

What is the purpose of twisted pair in UTP cables?

• To protect against electrical interference

• To increase network speed

• To enable wireless connections

• To prevent data collisions

What is the purpose of base in Ethernet standards?

• To refer to baseband signalling

• To indicate the maximum cable length

• To specify the number of pins in an RJ-45 connector

• To define the type of network interface
