Which TWO of the following are core components of the Cisco Identity Services Engine (ISE) for policy enforcement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Active Directory Integration
The Policy Service Node (PSN) is responsible for policy decision and enforcement, and Active Directory integration is a key component for identity mapping. NAD (Network Access Device) is an external device that ISE controls, not a component of ISE itself. EAP-TLS is an authentication protocol, and Firepower is a separate security product.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active Directory Integration
Why this is correct
ISE integrates with Active Directory to retrieve user and group information for policy.
- ✗
EAP-TLS
Why it's wrong here
EAP-TLS is an authentication protocol used in 802.1X, not a component of ISE.
- ✓
Policy Service Node (PSN)
Why this is correct
PSN is a core ISE node that handles policy decisions and enforcement.
- ✗
Firepower Threat Defense
Why it's wrong here
Firepower is a separate Cisco security product, not a component of ISE.
- ✗
Network Access Device (NAD)
Why it's wrong here
NAD is an external device (e.g., switch, AP) that ISE manages, not a component of ISE.
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.
