The E20-665 exam includes 111 questions, and you have 90–120 to complete them. That makes pacing a real part of the challenge. Before test day, work out roughly how much time you can afford per question, get used to flagging a hard item and coming back to it instead of burning five minutes on one answer, and run at least a couple of full timed sessions in the ExamsTorrent test engine so the clock feels familiar when it counts.

The official blueprint divides the EMC Networked Storage-ns installation and troubleshooting into 4 domains. The main areas include Troubleshooting and Problem Resolution (25%), System Administration and Management (20%), Installation and Initial Configuration (30%). Each domain breaks down into its own subtopics, so scroll up to the complete exam outline above before you plan your study schedule.

Basic knowledge of storage networking, NAS concepts, and EMC NS series products; 6–12 months hands-on experience recommended Certification vendors do adjust these requirements from time to time, so we recommend confirming the current criteria on the official exam page — official E20-665 exam information before you register.

The E20-665 exam is the official test you need to pass to earn the Legato Certified Specialist / Networked Storage Specialist certification at the Specialist level. Passing it validates your skills to employers, and for many IT professionals it is a direct step toward better roles and better pay. It also connects to related credentials such as EMC Proven Professional, Legato Certification, so it is worth understanding where this exam sits on your certification path.

Official courses build a strong foundation, but a course alone rarely tells you whether you are actually exam-ready. Work through the E20-665 practice questions from ExamsTorrent afterwards to measure yourself against real exam difficulty.

The passing score for the E20-665 exam is 65–70%, and the official registration fee is $150–$200 USD. One thing candidates often overlook: if you do not pass, a retake means paying that fee again in full. It is a strong argument for drilling with the 111 practice questions from ExamsTorrent until your mock scores sit comfortably above the bar before you book a seat.
