Cybersecurity-Practitioner Cloud Security Practice Question
An administrator is configuring a secure IPsec VPN tunnel between an on-premises Palo Alto Networks firewall and a Prisma Access Remote Networks mobile gateway. During negotiation, Phase 2 fails. Where should the administrator check to view detailed IKE and IPsec negotiation error messages?
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
✓
Run the CLI command `tail follow yes mp-log ikemgr.log` or check the System and GlobalProtect logs in Panorama/Firewall.
IPsec VPN troubleshooting on Palo Alto Networks firewalls is performed using the CLI command `tail follow yes mp-log ikemgr.log` or through the System > Logs > System/GlobalProtect or CLI operational commands.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Review the AWS VPC Flow Logs in the Amazon CloudWatch console.
Why it's wrong here
Incorrect. VPC Flow Logs record IP traffic metadata, not IPsec cryptographic negotiation errors.
- ✓
Run the CLI command `tail follow yes mp-log ikemgr.log` or check the System and GlobalProtect logs in Panorama/Firewall.
Why this is correct
Correct. The ikemgr log contains detailed IKEv1/IKEv2 and IPsec Phase 1/Phase 2 negotiation debugging output.
- ✗
Navigate to Prisma Cloud Compute > Monitor > Audit logs.
Why it's wrong here
Incorrect. Prisma Cloud Compute logs container runtime events, not firewall IPsec tunnels.
- ✗
Open the WildFire submission report for the crypto module hash.
Why it's wrong here
Incorrect. WildFire analyzes malware files.
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.
