PCNSE Secure Access and VPN Practice Question
A network engineer is configuring a new GlobalProtect gateway to provide remote access. Which TWO items are required for the gateway to function properly?
⚠ Common exam trap
Test-takers frequently confuse optional features like authentication profiles or split tunneling as requirements, when in fact the core mandatory components are the gateway certificate and an IP pool for client addressing.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A certificate for the gateway
A certificate is required for the GlobalProtect gateway to establish a TLS/SSL VPN tunnel with the GlobalProtect client. The gateway uses this certificate to authenticate itself to clients during the TLS handshake, ensuring the client is connecting to a trusted gateway. Without a valid certificate, the client will reject the connection, and the gateway cannot function.
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 certificate for the gateway
Why this is correct
Required to secure the TLS tunnel.
- ✗
An authentication profile
Why it's wrong here
Optional; authentication can be handled by the portal.
- ✓
An IP pool for client IP assignment
Why this is correct
Required to assign IP addresses to connecting clients.
- ✗
A split tunneling configuration
Why it's wrong here
Optional; defines which traffic goes through the tunnel.
- ✗
A clientless VPN configuration
Why it's wrong here
Not required for GlobalProtect gateway; used for browser-based access.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
