Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 321

A company is deploying new Cisco switches on a local network. The network engineer must configure TACACS+ between the switches and Cisco ISE. What configuration value is mandatory on the switch and Cisco ISE?

Answer options

• A. Authentication Profile
• B. CoA Port
• C. Shared Secret
• D. Key Encryption Key

Correct answer: C

Explanation

The Shared Secret is crucial for TACACS+ as it is used to encrypt the communication between the switches and Cisco ISE, ensuring secure authentication. The other options, while important in different contexts, are not required for the basic TACACS+ setup; thus, they do not fulfill this specific need.
