Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Monitor > Logs > Threat.
Why it's wrong here
Threat logs record malware and vulnerability exploits.
- ✗
Panorama > Cloud Services > Audit Log.
Why it's wrong here
Audit logs track administrative actions in Panorama.
- ✓
Monitor > Logs > System (filtering for IKE or IPsec events) or viewing tunnel status.
Why this is correct
System logs record IPsec and IKE negotiation details, encryption/hash mismatches, and phase failures.
- ✗
Monitor > Logs > URL Filtering.
Why it's wrong here
URL filtering logs track web browsing categories.
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.
