SSE-Engineer Prisma Access Troubleshooting Practice Question
An administrator configures a new Service Connection in Prisma Access to allow mobile users to access resources in the corporate data center. However, traffic from mobile users cannot reach the data center. The administrator confirms that the IPsec tunnel is up. What is the most likely cause of this issue in Panorama?
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
✓
The internal subnet routes associated with the Service Connection have not been added to the Mobile Users Explicit Proxy or Split Tunnel configuration.
When setting up Service Connections, administrators must update the Mobile Users explicit proxy or explicit routing settings (specifically pushing internal routes via the GlobalProtect agent config) so that clients know to send data center traffic through the Prisma Access tunnel.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Panorama requires a reboot to activate Service Connections.
Why it's wrong here
Panorama configuration pushes do not require a system reboot to apply networking settings.
- ✓
The internal subnet routes associated with the Service Connection have not been added to the Mobile Users Explicit Proxy or Split Tunnel configuration.
Why this is correct
Mobile users will not route traffic destined for the corporate data center into Prisma Access unless the corresponding internal subnets are defined in their split tunnel / routing configuration.
- ✗
The GlobalProtect client version is outdated on all endpoints.
Why it's wrong here
While client updates are recommended, they do not inherently block routing across an established Service Connection if basic routing rules are correct.
- ✗
The WildFire public cloud subscription has expired.
Why it's wrong here
WildFire subscription expiration impacts malware analysis, not basic routing over Service Connections.
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.
