What are two differences between switches and hubs?

What are two differences between switches and hubs? (Choose two.)
A. Switches are slower than hubs because of the extra addressing functions that switches perform.

  1. C & D would be correct, and it is proven in the explanation despite them providing the wrong letters.

    C. Switches are capable of sending and receiving data at the same time.

    Explanation/Reference:
    Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port only. This allows simultaneous communication across the switch, improving bandwidth.*

    *While A. COULD happen, today we have smart switches that can send and receive data as fast as a hub can repeat it, so that arguement is not always true, theoretically.

    D. Switches identify the intended destination of the data that they receive.

    Explanation/Reference:
    A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port only.

    1. Also, B is wrong because you can block certain ports on switches, so no traffic is allowed, or only specific traffic.

  2. What are two differences between switches and hubs? (Choose two)
    Switches are capable of sending and receiving data at the same time. Switches identify the intended destination of the data that they receive.

  3. A – Posibble (switch might be slower because works in 2-layer and analyze traffic),
    B – definitely WRONG,
    C – Correct (Full Duplex?),
    D – Correct

  4. The answere is C&D because:
    1) swithes are not slower than hubs
    2) Switches do not send data to all of the computers that are connected to them for efficiency. Hubs do this. Switches sends to the intend receiver by memorizing MAC adresess.
