Correct answer & explanation

First add the NAS, then define identity source, authentication policy, authorization policy, and finally test.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Add the NAS, then define identity source, then authentication policy, then authorization policy, then test
Why this is correct
This is the correct order because you must first add the Network Access Server (NAS) to ISE, then define the identity source (e.g., Active Directory) before creating policies that reference it, then configure authentication policy, then authorization policy, and finally test the setup.
- ✗
Define identity source, then add the NAS, then authentication policy, then authorization policy, then test
Why it's wrong here
This is incorrect because you need to add the NAS first so that ISE knows which devices to communicate with; defining the identity source beforehand is possible but adds no value until the NAS is configured.
- ✗
Add the NAS, then define identity source, then authorization policy, then authentication policy, then test
Why it's wrong here
This is incorrect because the authentication policy must be created before the authorization policy, as authorization rules reference the authentication result.
- ✗
Add the NAS, then authentication policy, then define identity source, then authorization policy, then test
Why it's wrong here
This is incorrect because the identity source must be defined before the authentication policy can reference it; otherwise the policy cannot be created properly.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
