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 SAProuter on an EC2 instance with an Elastic IP address
Deploying SAProuter on an EC2 instance with an Elastic IP address preserves the existing SAProuter configuration and ensures a stable endpoint that can be referenced in firewall rules and SAP routing tables. Option B (AWS NAT Gateway) is incorrect because a NAT Gateway is used for outbound internet traffic from private subnets and does not provide a persistent inbound endpoint for SAProuter connections. Option C (AWS Site-to-Site VPN) is incorrect because while a VPN provides secure connectivity between on-premises and AWS, it does not replace the need for SAProuter, which operates at the application layer. Option D (Application Load Balancer) is incorrect because an ALB is designed for HTTP/HTTPS traffic and cannot handle the proprietary protocol used by SAProuter.
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 SAProuter on an EC2 instance with an Elastic IP address
Why this is correct
EC2 with Elastic IP provides a stable endpoint and allows existing SAProuter rules to be reused.
- ✗
Use an AWS NAT Gateway to route traffic
Why it's wrong here
NAT Gateway is for outbound traffic, not for SAProuter's specific routing.
- ✗
Establish an AWS Site-to-Site VPN connection
Why it's wrong here
VPN is for network connectivity, not for SAProuter's application-level routing.
- ✗
Use an AWS Application Load Balancer
Why it's wrong here
ALB does not support SAProuter protocols (saprfc).

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.
