There are three separate certifications that require the 642-901 Building Scalable Cisco Internetworks (BSCI) exam. They are: Cisco Certified Network Professional (CCNP), Cisco Certified Design Professional (CCDP), and Cisco Certified Internetwork Professional (CCIP). This advanced exam, available in both English and Japanese versions, certifies that a candidate has the skills required to use advanced IP addressing and routing in order to implement scalability for those Cisco ISR routers that are connected to LANs and WANs. It is highly recommended that interested candidates complete the Building Scalable Cisco Internetworks course before attempting this exam. Topics covered include implementation of EIGRP and multi-area OSPF operations, describing integrated IS-IS, implementing Cisco IOS routing features, BGP for enterprise ISP connectivity, multicast forwarding and IPv6. Additional materials may be available for test preparation from the Cisco Marketplace Bookstore, available online from Cisco Press.
There Is No Reason to Worry with TestsForge
I always used to be worried whenever I was taking tests. This is because I did not want to have a problem with having to take the tests a second time. It was the kind of problem that led me to start downloading all of the different study guides that are available for each test. Sites like TestsForge allow me to get the specialized information for tests like the Cisco 642-901: BSCI. I get a study guide that includes everything I need in one easy to use source. The amount I pay for the different study guides is so small when put in comparison with the trouble it will cause if I cannot pass the test the first time.

Passed my Cisco 642-901 with flying colors yesterday!
I am beyond elated that I just passed my Cisco 642-901: BSCI exam! But I have to give credit where credit is due. And that would be right to you, the folks at TestsForge. I have no idea how you are able to create such a legitimate book for the Cisco 642-901 test! All I can say is: keep up the good work and keep doing what you're doing. I had expected to be studying for many more hours and weeks than it took me. Before I knew it, I had a Cisco 642-901 test date and was ready to perform my best. This was an awesome test experience for me start to finish.
