Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manual IPsec configuration
Why it's wrong here
Integration is automated.
- ✓
Automated tunnel provisioning via the Controller
Why this is correct
The integration automates the tunnel creation.
- ✗
Using a BGP peer
Why it's wrong here
BGP is used for routing, not tunnel establishment.
- ✗
Via a physical cable link
Why it's wrong here
It is a virtual tunnel.
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.
