Course Description

All questions are based on the Exam Objectives for the LPI Security Essentials (020-100) exam for all 5 domains of the exam, so you can take and pass the actual LPI Security Essentials (020-100) certification exam with confidence! 

In this course, I fully prepare you for what it is like to take the LPI Security Essentials (020-100) certification exam. These 6 full-length practice exams with 40 questions are timed for 60 minutes to help you pace yourself for the real exam. I have carefully hand-crafted each question to put you to the test and prepare you to pass the certification exam with confidence.


You won't be hoping you are ready, you will know you are ready to sit for and pass the exam. After practicing these tests and scoring an 85% or higher on them, you will be ready to PASS on the first attempt and avoid costly re-schedule fees, saving you time and money.

You will receive your total final score, along with feedback on each and every question, telling you exactly why each answer is correct, and which domain (and objective) you need to study more in order to pinpoint the areas in which you need to improve and perform some additional study. 


This course is designed to help prepare you for the LPI Security Essentials (020-100) certification exam and covers all five domains of the LPI Security Essentials (020-100) certification exam:

  1. Security Concepts (12.5%)

  2. Encryption (22.5%)

  3. Device and Storage Security (22.5%)

  4. Network and Service Security (25%)

  5. Identity and Privacy (17.5%)


Our LPI Security Essentials (020-100) practice exams provide you with realistic test questions and provide you with interactive, question-level feedback. 

I have some of the highest-rated CompTIA, Axelos, and LPI training courses on the Udemy platform and I invite you to visit my instructor profile to learn more about me, the certifications that I hold, and read the reviews of my courses. This course is consistently updated to ensure it stays current and up-to-date with the latest release of the LPI Security Essentials (020-100) exam, and also provides a 30-day money-back guarantee, no questions asked!

What others are saying about my other practice exam courses:

  • The questions were tough and it took me about 3 times for each test to reach 100%. I hope they are like the test... Really hope. Great training resources because the explanations are very useful. (Rick, 5 stars)

  • Great tests that provide something close to the scenario-based questions that the exam will show (it's hard as Udemy's platform isn't designed to allow them properly) Diverse questions. Really good explanations. Great learning tool for passing the test as the exams cover a lot off! (Aimee, 5 stars)

  • This course of practice exams has some good concept reinforcing questions and does a good job of rotating/varying the types of questions asked. Highly recommend if preparing for the certification exam. (Matthew, 5 stars)

  • These questions are unique and well-conducted to prepare for the exam with relevant information. I am using multiple resources and this is definitely one to have. (Valdrin, 5 stars)


    Upon completion of this course, you will earn 6 CEUs towards the renewal of your CompTIA A+, Network+, Security+, Linux+, Cloud+, PenTest+, CySA+, or CASP+ certifications.

Once again a good pool of test questions from which you can learn a lot if you do something wrong. Please keep it up. I would be happy if there was something like this for LPI Open Souce Essentials (also with an associated course). Keep it up :-)

By Xavier on 12/18/2025

A lot of questions are being repeated multiple times. So it's actually just 2-3 different tests, not 6. Be aware of that.

By Jordan Day on 10/2/2025

Good examples for questions, it is not 240 unique questions but there is some variations of the questions. Many questions are reused through the separate exams. Still should be good enough to use as a reference.

By Meerim Nurbekova on 6/4/2025

The course has all the needed information for preparing for the security essentials exam. Overall the course is easy to follow and understand

By Stephen Davis on 3/17/2025

I heard about many different programs and means of studying for computer certifications -- ITProTV, Prof. Messer, and other Udemy courses. Since my first A+ cert, I have studied with Dion Training. I am now preparing for my seventh certification after passing the A+, Network+, Security+, Linux+, LPIC-1, Linux Essentials, and now, the LPI Security Essentials. The ONLY cert that I have NOT used Dion Training for was the LPIC-1 (because Dion Training doesn't offer a course in it.). Dion Training's preparation courses and exam prep test packs have been instrumental in my development as an IT professional. I HIGHLY recommend the courses offered at both Udemy and www.diontraining.com for ANYONE seeking to develop their IT skills.

By Andre Falcao on 2/1/2025

Some questions are duplicated on practice tests. But overall its, a good way to prepare and to study the exam topics

By Mouhamadou Niang on 1/27/2025
