    • ENVIA LA TRAMA A TODOS LOS SEGMENTOS LAN, TAMBIEN POR EL CUAL FUE RECIBIDA LA TRAMA

    • ENVIA LA TRAMA SOLO POR DONDE FUE RECIVIDO LOS SEGMENTOS LAN

    • ENVIA LA TRAMA A TODOS LOS SEGMENTOS LAN, MENOS POR EL CUAL FUE RECIBIDA LA TRAMA

    Correct Answer
    A. ENVIA LA TRAMA A TODOS LOS SEGMENTOS LAN, MENOS POR EL CUAL FUE RECIBIDA LA TRAMA
    Explanation
    Cuando un switch comprueba que el nodo destino de una trama es desconocido para él, envía la trama a todos los segmentos LAN, excepto por el cual fue recibida la trama. Esto se debe a que el switch utiliza una tabla de direcciones MAC para determinar a qué puerto enviar la trama. Si el destino no está en la tabla, el switch asume que se encuentra en otro segmento LAN y envía la trama a todos los demás segmentos para que el nodo destino pueda recibirla.

    • Transporte

    • Presentacion

    • Aplicacion

    Correct Answer
    A. Presentacion
    Explanation
    The correct answer is "Presentacion". The Presentation layer of the OSI model is responsible for the translation, transformation, formatting, and syntax of data.

    Los intervalos de redes clase A se encuentran entre

    • 255.0.0.0 HASTA 255.255.0.0

    • 1.255.255.255 HASTA 255.225.0.0

    • 1.0.0.0 HASTA 255.0.0.0

    • 1.0.0.0 HASTA 126.0.0.0

    Correct Answer
    A. 1.0.0.0 HASTA 126.0.0.0
    Explanation
    The correct answer is "1.0.0.0 HASTA 126.0.0.0" because these IP addresses fall within the range of Class A network addresses. Class A networks have a range of 1.0.0.0 to 126.0.0.0, with the first octet ranging from 1 to 126. The other options provided in the question either exceed the valid range for Class A networks or fall within the range of Class B or Class C networks.

    • 255.0.0.0

    • 255.255.0.0

    • 125.125.0.0

    Correct Answer
    A. 255.0.0.0
    Explanation
    The given IP address 125.0.0.0 belongs to the class A range. In class A, the default subnet mask is 255.0.0.0. This subnet mask allows for a large number of network addresses, with the first octet representing the network portion and the remaining three octets for host addresses. Therefore, the correct answer is 255.0.0.0.
