Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
cisco-av-pair = redirect-url=http://ise.example.com
Why it's wrong here
This is not the correct attribute name for CWA.
- ✓
cisco-av-pair = url-redirect=https://ise.example.com:8443/guestportal/gateway
Why this is correct
This is the correct syntax for the redirect URL attribute.
- ✗
cisco-av-pair = redirect-to=https://ise.example.com
Why it's wrong here
This is not a valid RADIUS attribute for CWA.
- ✗
cisco-av-pair = url-redirect-acl=REDIRECT_ACL
Why it's wrong here
This attribute defines the ACL name, not the URL itself.
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.
