Correct answer & explanation
Define IKE policy
The correct order for configuring a site-to-site IPsec VPN is: first define the IKE policy (Phase 1 parameters), then define the IPsec transform set (Phase 2 parameters), then create the crypto ACL to match interesting traffic, then configure the crypto map to bind all parameters, and finally apply the crypto map to the outgoing interface.

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.
