The 640-823 exam, officially known as Cisco Interconnecting Cisco Networking Devices Part 1, is the Cisco test that leads to the CCENT (Cisco Certified Entry Networking Technician) certification at the Associate level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as Cisco CCNA Routing and Switching, CCENT (legacy).

The 640-823 exam contains 45–55 (varies) questions, and you have 90 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.

The passing score for the 640-823 exam is Variable scaled score (commonly ~804/1000, Cisco scaled scoring system), and the official registration fee is USD 125 (historical pricing; retired exam). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.

No formal prerequisites (entry-level certification). Basic understanding of computer networks recommended.
