Una amistad me informo que en el examen sobre las simulaciones practicas se tienen otros ejercicios que no aparecen en este banco de preguntas, se tiene informacion sobre esos nuevos simulaciones ???
Como lo dijimos en muchas oportunidades, Cisco actualiza las preguntas de sus exámenes de manera periódica, así que siempre existe la posibilidad que cada persona se pille nuevas preguntas, nosotros vamos actualizando las preguntas cada lunes en la medida que dichas preguntas sean publicadas. Lastimosamente por ahora no tenemos información de esas nuevas preguntas que mencionas, de todas formas siempre estamos buscando nueva información, y de encontrar esa información obviamente actualizaremos el banco.
