Multiple choice

Hub operates on __________ layer.

  1. Physical

  2. Data Link

  3. Network

  4. Transport
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multiple choice

Router operates on __________ layer.

  1. Physical

  2. Data Link

  3. Network

  4. Transport
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A router operates at the Network layer (Layer 3) because it uses logical addresses (IP addresses) to route packets between different networks.

Multiple choice

What OSI layer does the Router operate?

  1. Phyisical

  2. Data

  3. Transport

  4. Network
Reveal answer Fill a bubble to check yourself
D Correct answer
