The Cisco 642-813 (Implementing Cisco IP Switched Networks) test is a Switch exam in the Routing and Switching Cisco career track, and if you have designs on becoming a Cisco Certified Network Professional CCNP or a Cisco Certified Design Professional CCDP, you must first pass this hurdle.
This is a test for network engineers who have a certain amount of experience. If this is you, you most definitely should know how to successfully plan, configure, and verify enterprise switching solutions that are very complex in nature, using Cisco’s Campus Enterprise Architecture. You must also have expertise in the secure integration of voice, video, VLANs, and WLANs into campus networks.
The Cisco 642-813 Switch exam lasts for two hours and has 35-45 questions on it. Since there is no e-learning associated with this Switch course at Cisco, you would do well to study with an online learning service, like TestsHead. This online learning tool has real answers to real questions, and many of these will be on the actual exam. With TestsHead.com, you get instant access and highly detailed, accurate answers from professionals in the field. This is a company that specializes in providing IT certification study materials.
By all means, you should use more conventional means of study if you feel more comfortable with them, but be sure to take some sort of interactive practice tests before you take the exam.
