ANS-C01 Network Security, Compliance and Governance Practice Question
A company needs to securely connect an on-premises data center to AWS using multiple VPN tunnels. The security team requires that all traffic between the VPC and on-premises be encrypted and that the tunnels use a second authentication mechanism beyond pre-shared keys. Which solution meets these requirements?

Correct answer & explanation
✓
Use AWS VPN CloudHub with multiple VPN connections and configure certificate-based authentication for each tunnel
AWS VPN CloudHub allows multiple VPN connections with BGP routing and supports certificate-based authentication (mutual TLS) for each tunnel, providing a second authentication mechanism beyond pre-shared keys. Option A is incorrect because AWS Client VPN is designed for individual remote users, not for site-to-site connectivity between an on-premises data center and a VPC. Option B is incorrect because AWS Transit Gateway with VPN attachments uses pre-shared keys by default and does not support certificate-based authentication for the VPN tunnels. Option D is incorrect because while AWS Direct Connect with a public VIF and an IPsec VPN over it can provide encrypted traffic, the VPN itself typically relies on pre-shared keys, not a second authentication factor.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Client VPN with mutual authentication
Why it's wrong here
Client VPN is for remote users, not site-to-site connectivity.
- ✗
Use AWS Transit Gateway with VPN attachments and configure pre-shared keys
Why it's wrong here
Pre-shared keys do not provide a second authentication factor beyond the key itself.
- ✓
Use AWS VPN CloudHub with multiple VPN connections and configure certificate-based authentication for each tunnel
Why this is correct
CloudHub supports multiple tunnels and certificate-based authentication for enhanced security.
- ✗
Use AWS Direct Connect with a public VIF and establish an IPsec VPN over the Direct Connect connection
Why it's wrong here
Encryption is added via VPN, but authentication still relies on PSK, not a second factor.
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.
