Ultimate AWS Certified Developer Associate 2026 DVA-C02 vs CompTIA Security+ (SY0-701) Complete Course & Practice Exam

The course spans 50+ hours of video covering all six DVA-C02 exam domains — Deployment, Security, Development with AWS Services, Refactoring, Monitoring, and Troubleshooting. Deep dives into DynamoDB, SQS, SNS, Lambda, API Gateway, CodePipeline, and X-Ray are consistently praised as thorough and up-to-date following the DVA-C02 blueprint revision. A small number of reviewers flag the Lambda and DynamoDB advanced sections as feeling rushed compared to the networking coverage.

Maarek holds 11 AWS certifications and has trained over 1.5 million students across his Udemy catalogue. Reviewers consistently describe his teaching style as exceptionally clear — he breaks complex multi-service interactions into logical architectural diagrams and follows up with live console walkthroughs students can reproduce on the AWS free tier. His 11x certified credibility means explanations carry genuine practitioner weight, not just exam-guide paraphrasing.

At Udemy sale price (~$15–25, which is the price at nearly every purchase given Udemy's near-perpetual promotion cycle), 50+ hours of DVA-C02 content represents one of the highest content-per-dollar ratios available for AWS certification prep. Lifetime access with free ongoing updates is a key differentiator versus subscription-gated platforms.

The course covers all five SY0-701 exam domains across 264 modules and 31 hours of video, spanning General Security Concepts, Threats and Vulnerabilities, Security Architecture, Security Operations, and Security Program Management. Reviewers on OpenCourser and Reddemy consistently praise the structured domain breakdown, acronym walkthroughs, and the alignment with official CompTIA exam objectives. The main content gap flagged by multiple learners is limited hands-on lab simulation — the course is predominantly lecture-based, which can make performance-based question (PBQ) preparation less thorough than the actual exam requires.

Jason Dion brings over 20 years of IT and cybersecurity experience to the course and is consistently described by reviewers as easy to follow, thorough, and amiable. OpenCourser reviewers Victor Cabrales and Mark Guillen both called out his clear explanations and acronym-focused teaching style as the course's standout feature. He holds CompTIA Platinum Partner status, and Dion Training's 4.6+ star network-wide rating across 2 million+ students reinforces his reputation as one of the most reliable certification prep instructors in the field.

The course is almost always available on Udemy for $13–$20 during the platform's frequent sales, a price point that Reddemy commenters repeatedly highlight as exceptional for 31 hours of content plus practice materials. One Reddemy user noted purchasing both the course and the separate practice exam set for approximately $13 each during a sale. At that price, Dion's course delivers one of the lowest cost-per-hour ratios of any paid Security+ preparation resource, with lifetime access and periodic content updates included.

Multiple reviewers who passed SY0-701 on their first attempt credit Dion's course as their primary preparation resource, including John T. (Medium), who passed in under two months with no prior cybersecurity background. The course's exam-focused framing maps tightly to Security+'s five domains and the career skills they represent — threat analysis, security architecture, and incident response. However, the lecture-only format and absence of hands-on labs mean learners entering cybersecurity roles will need additional practical experience beyond what the course alone provides.

Like most Udemy courses, learner support is limited to the platform's Q&A section — there is no live instructor interaction or direct email support. One Reddemy user flagged a structural navigation issue, noting difficulty jumping directly to specific domains without watching the course sequentially. Response times in the Q&A section are generally adequate for a high-enrollment course, but learners who need real-time feedback or personalized guidance will need to seek supplementary communities such as the r/CompTIA subreddit.
