CCTE R81.20 case studies
CCTE R81.20 · Put your knowledge to work in context.
The CCTE R81.20 - commonly written out as the Check Point Certified Troubleshooting Expert R81.20 - is an advanced, hands-on certification aimed at security engineers, firewall administrators, and support staff who already work with Check Point Quantum security gateways and management servers and who want to prove they can diagnose and resolve faults rather than simply configure policy. It sits above the entry-level administrator track: instead of asking you to build objects and rules, it asks you to explain why traffic is dropped, why a management server will not start, or why a cluster member fails over unexpectedly. The CCTE R81.20 case studies are 5 cases and about 2,644 words.
