My good friend Daniel Rodriguez over at blog.initialdraft.com has just released his CCIE Flashcards product. Available on the app store and GooglePlay for the Android market This product contains over 500 flashcards with questions and answers relating to all elements of the CCIE R&S Blueprint.
The app is priced around $4 and in my opinion is very good value for money.
He is also developing a CCNA and CCNP product which should be released soon.
This product alone will not be enough for you to pass the CCIE Lab exam, but if you are sat on the bus or at the dentist and have ten minutes you can just fire it up and do quick refresh on a few topics.
Nice on Daniel!
