Cybersecurity-Apprentice Network Security Practice Question
A company requires remote workers to establish a secure tunnel back to the corporate data center using GlobalProtect. Which component authenticates the users before assigning an IP address pool?
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
✓
An Authentication Profile linked to the GlobalProtect Portal/Gateway configuration.
GlobalProtect Portal and Gateway interact with Authentication Profiles (LDAP, SAML, RADIUS) to authenticate users before tunnel establishment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A Security policy rule with an explicit source user match.
Why it's wrong here
Security policies evaluate traffic after the session is established and authenticated.
- ✗
A decryption policy specifying a trusted CA certificate.
Why it's wrong here
Decryption policies handle TLS inspection, not user authentication.
- ✗
A NAT rule translating the public IP to a private IP.
Why it's wrong here
NAT maps IP addresses; it does not perform user authentication.
- ✓
An Authentication Profile linked to the GlobalProtect Portal/Gateway configuration.
Why this is correct
Authentication profiles handle credential validation for GlobalProtect users.
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.
