Explanation

TACACS+ is Cisco ISE's protocol for Device Administration (A) because it handles authentication, authorization, and accounting (AAA) for network administrators logging into infrastructure devices like routers and switches - controlling who can log in and what commands they're permitted to run.

Distractors:

  • B (Device Profiling) is wrong because profiling uses DHCP, HTTP, and SNMP to identify and classify endpoints (laptops, phones, IoT) - completely unrelated to admin access control.
  • C (Centralized policy management) is a broad architectural description of ISE itself, not a discrete feature that TACACS+ belongs to.
  • D (Guest access management) involves web portals and sponsor workflows for temporary visitor access - TACACS+ plays no role there.

Memory tip: Think "TACACS = Taking Admin Control of Cisco Switches" - it exists specifically so network engineers can log into devices under controlled, audited conditions, which maps directly to Device Administration.
