Hola, estoy realizando el curso de CCNP ENARSI.
Estoy revisando el banco de preguntas y me ha surgido una duda.
Cuando hay una pregunta que tiene una respuesta errónea, la respuesta se corrige en el banco de preguntas, o simplemente queda corregida en el foro de preguntas.
Espero haberme explicado bien.
Espero su respuesta.
Un saludo
Buenas tardes,
en la pregunta 732 nos da como respuestas correctas la C y la E, pero no aparece la , la ultima opcion es la D.
Espero su respuesta gracias
En realidad, debería ser C y D, ya que una de las opciones deniega las rutas con el tag de 90, y la otra de las opciones aplica el route-map al protocolo de enrutamiento EIGRP. Esto se hace porque quieres evitar que las rutas EIGRP que ingresaron al dominio OSPF VUELVAN de nuevo a EIGRP a través del router R2.
