Недавно сдал экзамен 642-889 — в рамках обновления своего ССNP и получения CCNP SP. Курсы не покупал, обошелся интернетом, а также старым курсом Cisco MPLS, который у меня в твердой копии.
Далее список тем и подобранные (не всегда удачно) ссылки на материалы для изучения — кому-то может сэкономить час времени на гугление.
Список тем взят отсюда
