PCNSA Managing Objects Practice Question
Drag and drop the steps to configure a site-to-site IPsec VPN on a Palo Alto Networks firewall into the correct order.
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 IKE gateway, then IPsec crypto profile, then tunnel interface, then static route to tunnel interface, then security policy allowing VPN traffic.
IPsec VPN setup involves IKE gateway, IPsec profile, tunnel interface, security policy, and routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure IKE gateway, then IPsec crypto profile, then tunnel interface, then static route to tunnel interface, then security policy allowing VPN traffic.
Why this is correct
This is the correct order because IKE gateway defines Phase 1 parameters, IPsec crypto profile defines Phase 2, the tunnel interface is created with the IPsec binding, the route directs traffic into the tunnel, and the security policy permits the traffic.
- ✗
Configure IPsec crypto profile, then IKE gateway, then tunnel interface, then static route, then security policy.
Why it's wrong here
This is incorrect because the IPsec crypto profile (Phase 2) should be configured after the IKE gateway (Phase 1), as Phase 2 parameters depend on the IKE gateway's settings.
- ✗
Configure IKE gateway, then IPsec crypto profile, then static route, then tunnel interface, then security policy.
Why it's wrong here
This is incorrect because the static route references the tunnel interface, which must be created before the route can be added.
- ✗
Configure security policy, then IKE gateway, then IPsec crypto profile, then tunnel interface, then static route.
Why it's wrong here
This is incorrect because the security policy should be created after the tunnel interface and route are in place to ensure proper traffic flow, and the VPN configuration itself must precede the policy.
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.
