SSE-Engineer Prisma Access Planning And Deployment Practice Question
An architect is designing a high-availability Remote Network location for Prisma Access. Which TWO methods can be used to ensure redundancy for branch office traffic connecting to Prisma Access? (Choose two)
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
✓
Deploy dual branch routers establishing independent IPSec tunnels to Prisma Access
Branch office redundancy in Prisma Access can be achieved by deploying redundant IPSec tunnels from the branch router to Prisma Access and utilizing BGP path selection, or by deploying redundant branch hardware devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy dual branch routers establishing independent IPSec tunnels to Prisma Access
Why this is correct
Dual branch routers provide hardware-level redundancy at the branch site.
- ✗
Enable VRRP directly across the Prisma Access cloud gateway public IP addresses
Why it's wrong here
Customers cannot run VRRP across cloud-managed Prisma Access endpoints.
- ✓
Configure redundant IPSec tunnels terminating on separate Prisma Access SPNs with BGP path selection
Why this is correct
Redundant tunnels to separate SPNs using BGP provide automatic failover.
- ✗
Configure Spanning Tree Protocol (STP) across the IPSec tunnel interfaces
Why it's wrong here
STP is not supported over cloud-terminated IPSec tunnels.
- ✗
Use L2TPv3 link aggregation across the cloud service edge
Why it's wrong here
L2TPv3 link aggregation is not a supported redundancy method for Prisma Access.
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.
