She opened the book to a dog-eared page: Troubleshooting RADIUS latency issues . Her finger traced the flowchart. Verify shared secret. Check certificate chain. Validate NAD (Network Access Device).

Elena smiled and looked down at the Cert Guide. On the cover, the Cisco logo stared back, impassive. She closed the book and whispered, "You ugly, beautiful brick of knowledge. We did it."

"There's a new version," he grunted. "The exam changed. And the CISO wants to deploy pxGrid to talk to the firewalls. You have two months."

Just as she leaned back, her SIEM dashboard lit up. An alert. 2:17 AM. A rogue access point had just appeared in the CFO’s wing. But unlike last time, the network didn't panic.

Then, a second later, a remediation portal popped up. "Your device does not meet security compliance. Please install the latest antivirus definitions." Check certificate chain

Then, the magic happened. The she had built from Chapter 14 kicked in. The rogue AP was not denied. That would be too easy. Instead, it was lured. ISE assigned it to a honeyed VLAN—a virtual terrarium of fake databases and tempting files. The attacker would think they had won. In reality, they were locked in a glass box.
