    • F.

      255.255.255.0

    Correct Answer
    D. 255.0.0.0
    Explanation
    The default subnet mask for a Class A network is 255.0.0.0. This subnet mask allows for a large number of network addresses and a small number of host addresses. In a Class A network, the first octet is used to identify the network, while the remaining three octets are used to identify the hosts within that network. Therefore, a subnet mask of 255.0.0.0 means that the first octet is used for the network address, while the remaining three octets are available for host addresses.

    Which network device uses a MAC address table to segment the network?

    • A.

      Concentrator

    • B.

      Hub

    • C.

      PBX

    • D.

      Router

    • E.

      Switch

    Correct Answer
    E. Switch
    Explanation
    A switch uses a MAC address table to segment the network. This table keeps track of the MAC addresses of devices connected to the switch and their corresponding ports. When a packet arrives at the switch, it checks the destination MAC address and forwards the packet only to the port where the device with that MAC address is connected. This allows the switch to efficiently send data only to the intended recipient, reducing network congestion and improving network performance.

    A strong password should contain:

    • A.

      Both uppercase and lowercase letters.

    • B.

      A word that is easy to remember, such as the name of a pet.

    • C.

      At least 8 characters, and a combination of letters, numbers, and characters.

    Correct Answer
    C. At least 8 characters, and a combination of letters, numbers, and characters.
    Explanation
    A strong password should have at least 8 characters, and it should be a combination of letters, numbers, and characters. This combination makes the password more complex and harder to guess or crack. Having both uppercase and lowercase letters adds an extra layer of security, as it increases the number of possible combinations. Using a word that is easy to remember, such as the name of a pet, makes the password vulnerable to dictionary attacks or guessing. Therefore, the correct answer is to have at least 8 characters, and a combination of letters, numbers, and characters.
