[AYUDA] Aca el Examen Final CCNA 3...

Hola, este es el examen que me toco dar la semana pasada. Es la forma B... por que como ya se habran dado cuenta, cambiaron la plataforma.

Espero les sirva. Eso LES PONGO EL EXAMEN EN INGLES, y abajo el que me toco dar a mi, son los mismos...

Me faltaron las 3 ultimas preguntas, las que no pude copypastear por que estaba el profe mirando jajaja

Un saludo!

Recuerda que ella no pudo copiar todo el examen, esas deben ser las que faltan.

Pero es raro, normalmente los examenes en Ingles tienen más preguntas que los examenes en Español, en todos los examenes que he visto, y no al revés.

Ella solo copio 45 preguntas, y si dice que le faltaron por copypastear 3 entonces el examen era de 48 preguntas...no? el examen en ingles tiene 50 preguntas pero esas 5 que posteo yo!! no estan.. ¿¿¿sera que es la version 3.1.1?????

cuando se conecta nannyta?????? para que aclare nuestras dudas...

Hola que tal amigos, en esta ocasion me tocara aportar informacion para este sitio, realmente estuve buscando mucho el examen de redes 3 el final 3.1.1 y nunca lo encontre, pero para ahorrarles trabajo a los demas aqui les dejo el final en ingles, es el de 47 preguntas, la verdad aun no se que sacare con este examen, ya que mañana lo tengo, asi que mañana les aviso que saque!!! bueno aqui se los dejo, alguna duda me avisan!! saludos de Mazatlan Mexico!!
