Cisco 640-821 CCNA INTRO Certification Exam Cisco Networking Technologies Exam 640-821... Continue Below To CCNA Exam Information and Cisco CCNA Articles. The real CCNA 640-821 Exam has a duration of 75 minutes to complete and has approximately 45 - 55 questions.
The Introduction to Cisco Networking Technologies exam 640-821 is one of the two qualifying exams available to candidates pursuing a two-exam option for CCNA. This exam tests content covered in the Introduction to Cisco Networking Technologies (INTRO) course including topics on Network Types, Network Media, Switching Fundamentals, TCP/IP, IP Addressing and Routing, WAN Technologies, Operating and Configuring IOS Devices, and Managing Network Environments. The Cisco 640-821 exam will certify that the successful candidate has important skills and knowledge necessary to describe and identify major network and WAN components, along with their function and purpose. All these objectives are designated from the Cisco.com website. Please note that CCNA Intro exam topics and objectives may change without notice, since technologies are always changing.
The Cisco CCNA certification is just the first step into Cisco networking and is the first stepping stone to higher certifications on the Cisco cert ladder. The Cisco CCNA is a prerequisite for CCNP, CCSP, CCDP, and recommended for CCIP certifications.
