Hola Avaro!!
relacionado a la siguiente pregunta:
187. While examining excessive traffic on the network, it is noted that all incoming packets on an interface appear to be allowed even though an IPv4 ACL is applied to the interface. Which two misconfigurations cause this behavior? (Choose two)
A. The ACL is empty
B. A matching permit statement is too broadly defined
C. The packets fail to match any permit statement
D. A matching deny statement is too high in the access list
E. A matching permit statement is too high in the access lisSi A Y E son las coorectas, entonces una Una ACL vacía permitirá todo el tráfico por defecto?
Saludos!!
Buen dia! Alvaro
26. Respuesta B.
Creo que D es la respuesta correcta. Cuando se habilita PortFast en el switch, STP coloca los puertos en el estado de reenvío inmediatamente, en lugar de pasar por los estados de escucha, aprendizaje y reenvío. Si la respuesta B no dijera «cuando se recarga el switch», habría sido la respuesta correcta, ya que cuando se reinicia el switch regresa a su ciclo normal.
Understanding Port Fast
Port Fast immediately brings an interface configured as an access or trunk port to the forwarding state from a blocking state, bypassing the listening and learning states. You can use Port Fast on interfaces connected to a single workstation or server, as shown in Figure 18-1, to allow those devices to immediately connect to the network, rather than waiting for the spanning tree to converge.
Interfaces connected to a single workstation or server should not receive bridge protocol data units (BPDUs). An interface with Port Fast enabled goes through the normal cycle of spanning-tree status changes when the switch is restarted.
corregirme si estoy equivocado, saludos !!
