SISE Network Access Device Administration Practice Question
When defining a Shell Profile for a TACACS+ administrator, which setting ensures the user is placed into privilege level 15 immediately upon login?
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
✓
Configure the 'Privilege Level' field to 15
The Default Privilege setting in the Shell Profile controls the initial privilege level upon successful authentication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set 'Attribute' to 'priv-lvl=15' in custom attributes
Why it's wrong here
This is not the standard field; the UI provides a dedicated privilege field.
- ✗
Set the 'Auto-Command' to 'enable 15'
Why it's wrong here
Auto-command is for executing a specific command upon login, not session level.
- ✓
Configure the 'Privilege Level' field to 15
Why this is correct
The Default Privilege attribute sets the initial level.
- ✗
Enable 'Maximum Privilege' in the command set
Why it's wrong here
Command sets do not control initial login privilege levels.
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.
