I passed the CISSP exam today! For a long time, I kept postponing it, thinking it would be too difficult. However, the daily questions shared in this group helped me build the right mindset. The tips and guidance from those who had already cleared the exam were also incredibly helpful. I used the following study resources: OSG and Official practice tests cissp.app app - Helps with time management and provides clear explanations. Destination Cert YouTube series and their app for questions Eric Cornard CISSP study guide and other you tube videos/Questions

Most CISSP candidates can define unicast. Fewer can explain why IPv6 quietly killed broadcast, or why anycast makes DDoS attacks harder to land. Four IP communication patterns. Four different security postures. Domain 4 expects you to know all of them. → Unicast (one-to-one): clean audit trails, perfect for forensics, and where the bulk of your monitoring effort lives. → Broadcast (one-to-all): IPv4 only. Loud, leaky, and the reason DHCP snooping exists as a control. → Multicast (one-to-group): efficient by design, but explicit group membership is the security boundary you have to watch. → Anycast (one-to-nearest): same IP, many servers, BGP routes traffic to the closest one. It's what keeps DNS root servers and CDNs standing under attack. Save this for your Domain 4 review. https://media.licdn.com/dms/image/v2/D4E22AQFPc1ytBrVJYg/feedshare-image-high-res/B4EZ5uHKLlGQAk-/0/1779963831384?e=1781740800&v=beta&t=8CcKKfad3Hv7_YtJwQSSTHxUB3zxk-fJlmfDzDHU-QU

I’m excited to let you all know that I passed the exam today. I’m still pretty overwhelmed am not sure how well I did but I guess it was good enough!

105 questions, 45 minutes left on the clock. After failing in February, I've provisionally passed. What changed between February and today: Mindset shift — I stopped thinking like a technician and started thinking like a manager. Every question, I asked myself: "What would a CISO advise?" not "What would I configure?" This was the single biggest change. Reading discipline — More than half my practice errors came from misreading questions, not from lack of knowledge. I trained myself to identify the qualifier (FIRST, BEST, PRIMARY), any constraints (budget, minimal impact), and dual requirements (balance X with Y) BEFORE looking at the answers. Trust your first instinct — On my mock exams, I lost points every time I changed an answer. If your first choice is based on reasoning, don't switch it because of doubt. Time management — I set milestones: Q50 by 1 hour, Q100 by 2 hours. This kept me from rushing at the end. I finished with plenty of time. Study approach — I used practice questions to identify patterns in my mistakes, not just to memorize content. Knowing WHY you got something wrong matters more than knowing the right answer. Tips for exam day: The exam tests whether you can make security DECISIONS, not whether you can recall facts "More security" isn't always the best answer — look for what's proportional and meets ALL the requirements in the question Policy/governance before technology. Assessment before implementation. Root cause fix before compensating controls. Don't panic if questions feel hard — the CAT adapts. Hard questions mean you're doing well. Thank you all for the support through this journey. The group study sessions made a real difference. For those still preparing — the knowledge is probably already there. Focus on how you READ and THINK through questions, not just what you know. See you on the other side. 🏆
