After earning my AWS AI Practitioner certification on June 6, 2025, I was eager to keep my AWS momentum going. To deepen my understanding of core AWS services and gain a broad overview of the ecosystem, I decided to tackle the AWS Cloud Practitioner exam next. Two weeks later, I sat for the exam — and I’m excited to say I passed with a score of 807/1000! ✅ You can check my verification link here.
This was my second AWS certification. After earning the AI Practitioner, I wanted to strengthen my foundational understanding of the AWS ecosystem before jumping into the SAA-C03. Here’s what my preparation looked like.
AWS provides excellent foundational courses on AWS Skill Builder. The main ones I completed:
I followed Stéphane Maarek’s highly regarded Ultimate AWS Certified Cloud Practitioner CLF-C02 course and explored every part thoroughly:
| I practiced extensively with **Udemy’s 6 Practice Exams | AWS Certified Cloud Practitioner CLF-C02** (390 questions), reviewing every answer thoroughly to understand the logic behind it. |
While preparing, I found the AWS-Solutions-Architect-Associate-Exam-2025 repo by sv222. Although built for the SAA-C03 exam, it offers a well-organized overview of the most-used AWS services and architectures — very helpful for polishing my knowledge and seeing the bigger picture.
While my final score wasn’t as high as I’d hoped (I was aiming for 900+), I’m proud of the progress. The hands-on labs, practice questions, and review materials built a solid foundation that will help as I aim for the AWS Solutions Architect — Associate (SAA-C03) next.

On June 6, 2025, I passed the AWS Certified AI Practitioner (AIF-C01) exam with a score of 885 out of 1000. This certification marks my entry into the field of cloud-based artificial intelligence and machine learning, and in this post I’ll share my complete journey — from study materials and hands-on labs to dealing with technical hurdles during the exam.
With AI transforming industries rapidly, I wanted to gain both theoretical understanding and practical experience with AWS AI/ML services. This certification was ideal for establishing foundational knowledge while validating my ability to apply AI responsibly within the AWS ecosystem.
I started with the official AWS Skill Builder course. It covers all five domains of the exam:
I created a comprehensive study document by following each video and caption. This became my centralized notes with a domain-by-domain overview of all topics.
I then followed the Ultimate AWS Certified AI Practitioner AIF-C01 course on Udemy by Stéphane Maarek. The lessons were clear and hands-on. I especially appreciated the deep dive into real-world use cases, and reviewed the slide decks repeatedly to reinforce the core services and their ideal use cases.
To go beyond theory, I practiced with Andrew Brown’s free YouTube course, which focuses on hands-on AWS experience. Here’s what I practiced and learned:
I completed 20 free and 65 paid questions from AWS Skill Builder, plus all 4 sets of Stéphane Maarek’s practice tests on Udemy. I didn’t just answer questions — I analyzed each incorrect answer and reviewed the concepts behind every distractor. This review cycle helped reinforce weak areas.
Originally, I scheduled the exam for May 30, 2025, but Pearson VUE’s software failed to launch on my office laptop. I rescheduled to June 6, before Eid-al-Adha, using my personal laptop — and this time the proctoring setup worked smoothly. The format included single- and multiple-choice questions, case studies, and match-type questions (matching services to their use cases). The questions were more conceptual and real-world-focused than the practice sets, but my hands-on experience helped me reason through them confidently.
If you’re on your way to becoming AWS Certified, I’d be happy to share my study doc or help you plan your prep. Let’s build responsibly with AI! You can view my earned badge on Credly.

Embarking on the journey to earn the CEH Master certification was a transformative experience for me. It was more than just a credential; it was a commitment to deepening my knowledge and skills in ethical hacking and cybersecurity. As a professional already immersed in the cloud and cybersecurity domain, the CEH Master certification represented a significant milestone in my career. Here, I want to share my journey — the challenges I faced, the strategies I employed, and the lessons I learned.
The field of cybersecurity is constantly evolving, and staying relevant requires continuous learning. The CEH (Certified Ethical Hacker) certification is globally recognized and provides a comprehensive understanding of ethical hacking techniques and tools. I purchased this certification for $450 during the EC-Council cybersale, as it not only tests theoretical knowledge but also validates hands-on skills through a practical exam. This dual focus on knowledge and application made the CEH Master designation particularly appealing, aligning perfectly with my career goals.
Earning the CEH Master certification involved tackling two components: the Practical exam and the ANSI (knowledge) exam. The following sections break down my approach to each.
I began by thoroughly reviewing the exam blueprint and analyzing previous question types. The CEH Practical exam required me to solve 20 real-world challenges within 6 hours. This gave me a clear understanding of the exam’s structure and helped me identify the key areas to focus on.
The CEH Practical book is divided into 20 modules, each with its own PDF. To streamline my preparation, I combined all of them into one document using Foxit PDF Editor Pro, then bookmarked each module with multiple colors — along with topics and tasks — to create a clear overview. Without this overview, starting from the beginning felt overwhelming and disorganized. Bookmarks helped me locate sections and navigate the material far more effectively.
Once I started, I read each task and the associated concepts, focusing on: what the concept is about, why it is necessary, how the problem can be solved, and which tools or techniques apply. After grasping the theory, I practiced each task in the iLabs environment, which provides six machines (Parrot OS, Windows 11, Windows Server 2019, Windows Server 2022, Ubuntu, and Android). I repeated each task two or three times to build confidence.
If a task didn’t work as described in the manual, I referred to video tutorials for guidance. I was meticulous and did not skip a single task. This rigorous approach took roughly two months of serious, committed practice.
Some tasks required accessing systems through specific services — FTP, SMTP, SMB, RDP, SSH, NetBIOS, and SNMP. Without gaining access to the machines running these services, it was impossible to proceed. So I focused on learning and practicing techniques to enumerate and interact with each: understanding their configurations, vulnerabilities, and how to exploit them effectively. (My notes.)
After completing all modules, I assessed my understanding and revisited the areas where I felt less confident — revisiting both theory and practical exercises. The areas I concentrated on included networking, enumeration, privilege escalation, sniffing, DDoS, session hijacking, hacking web servers, hacking web applications, hacking wireless networks, and cryptography. Dedicating extra time here solidified my knowledge before the exam.
After finishing iLabs, I extended my preparation to CEH Engage, which provides advanced, dynamic scenarios for testing practical skills. Working through these challenges sharpened my ability to think critically and apply solutions under time constraints. (My notes.)
I scheduled my CEH Practical exam for December 20, 2024, at 1:45 AM — deliberately choosing a late-night slot for a stable connection and a quiet environment. I adjusted my routine and slept during the day to stay well-rested. By this point, with weeks of focused practice behind me, I was confident and calm. I had done the hard work; it was just a matter of showing up and performing.
My exam started right on schedule. After the room and passport checks, the proctor explained the rules and granted permission to begin. The environment was similar to CEH Engage: one machine running Parrot OS and another running Windows 11, with three network subnets to work with (10.10.55.0/24, 192.168.44.0/24, and 192.168.200.0/24).
I began by scanning the networks with Nmap:
nmap -sV -sC -A -T4 -oN 10_scan_results.txt 10.10.55.0/24
Breakdown of the options:
-sV — detect service versions-sC — enable the default set of scripts for additional service information-A — enable OS detection, version detection, script scanning, and traceroute-T4 — set an aggressive timing template for faster scans-oN — write plain-text output to a file10.10.55.0/24 — the target subnetThe -oN flag was especially useful: it produced a text file that made it easy to search for network details and services while solving questions. Parrot OS was a bit slow, but manageable. After three hours I had completed 14 tasks and took a short break, then finished the rest within two more hours — about five hours total. Before submitting, I reviewed all questions and answers twice. When I told the proctor I was ready, they asked, “Are you sure?” I was. After submitting, I saw my result: 200/200. And just like that, it was a good, good, good morning!
The proctor guided me to download the certificate from the ASPEN portal. It generated automatically and arrived instantly. Seeing it felt incredibly rewarding — a tangible recognition of all the time, effort, and perseverance I had invested. Alhamdulillah!
After the Practical exam, I shifted focus to the CEH ANSI exam, which tests theoretical knowledge of ethical hacking concepts, methodologies, and tools. I scheduled it for January 11, 2025, at 11:00 AM, building on the modules I’d already studied for the Practical.
I combined all modules into a single PDF — a comprehensive overview of every concept in one place. The final document ran to 3,451 pages. I bookmarked each module and Learning Objective (LO), color-coding categories and sections so I could quickly locate topics and focus where I needed most.
Given limited time, I prioritized the Learning Objectives in each module. When I struggled with an LO, I referred to the relevant portions of the text, paying close attention to bolded terms and key highlights. This let me cover the critical topics efficiently without reading all 3,451 pages in detail.
I used the Cyber Quotient platform, which offers multiple-choice questions organized by topic. Its biggest benefit was highlighting my weaker areas, so I could focus my effort where it counted and build confidence topic by topic.
Cyber Quotient also provided two simulated exams of 125 questions each, mirroring the real CEH ANSI exam in type and pattern. These gave me a realistic experience of the structure and timing, and helped me sharpen my time management.
For final preparation, I used the Certified Ethical Hacker v12 Practice Exams by Viktor Afimov on Udemy ($13) — 4 tests with 475 questions. Each included detailed explanations, so whenever I missed a question I reviewed the reasoning and reinforced the concept.
I woke at 4:00 AM for a last review ahead of my 11:00 AM exam. I began with full concentration, touching every question and marking uncertain ones for review to keep momentum. It took about 3 hours 40 minutes of the 4-hour window. The exam wasn’t entirely smooth — I hit two disconnections, and just before submitting, Chrome froze. The proctor calmly advised me to switch to Firefox, and after logging back in I submitted successfully.
Checking my ASPEN dashboard, I saw I had scored 118 out of 125 — a pass, with a detailed breakdown across all sections.
The proctor said it would take 5–10 days; the certificate would appear on the ASPEN dashboard and arrive by email. To my delight, I received it within 5 days.
Along with the ANSI certification, I also received the CEH Master certification — the completion of a dream achievement. This milestone validated my skills and confirmed my commitment in the field of ethical hacking and cybersecurity.
The journey to the CEH Practical, ANSI, and Master certifications was a rewarding experience in my pursuit of expertise in ethical hacking and cybersecurity. My preparation focused on hands-on practice for the Practical exam, consolidating all modules into a unified resource for the ANSI exam, and refining my understanding through simulated exams and targeted study. With determination and a focused approach, I completed both exams and earned the CEH Master certification — a significant achievement, and a deeper commitment to staying ahead in an ever-evolving field.
