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

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. 🏆

What a relief to pass the CISSP exam. 🎉🎉 I’ll be honest, I didn’t read the entire book. I skipped two or three domains entirely. I attended the May Brook Cohort class and used Claude to better understand specific concepts and shore up my weak domains. One thing I noticed: there’s no way to tell whether someone passed or failed just by watching them walk out. My recommendations — never second-guess your instincts, read each question twice, and make sure you’ve read all four answers before selecting one.

A long-tenured engineer has accumulated access across six business units through internal transfers. A recent audit flagged the account as having excessive privileges, but managers insist the access is "needed for cross-functional projects." What should you do FIRST? A. Disable unused entitlements based on the last 90 days of activity logs B. Initiate a formal access recertification with each respective data owner C. Implement a role-based access control model to replace direct grants D. Escalate to HR to enforce a job description review Come back for the answer tomorrow, or study more now!

Hi everyone, I’m excited to share that I provisionally passed the CISSP exam yesterday. It’s definitely been a challenging journey, but the hard work has paid off. To prepare, I used a mix of resources including the official ISC2 study guide, the Destination Certification mind maps, and Peter Zerger’s YouTube videos. For practice questions, I used this platform and the LearnZapp app. A huge thank you to everyone in this group for the support, and I wish you all the best on your own journeys!
