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
✓
AWS Transit Gateway Network Manager
AWS Transit Gateway Network Manager provides monitoring of BGP sessions, network topology, and VPN/Transit Gateway attachment status. Option A is incorrect because AWS Config tracks resource configuration changes but does not monitor real-time BGP session status. Option B is incorrect because VPC Flow Logs capture IP traffic metadata, not routing protocol status. Option D is incorrect because Amazon CloudWatch with Transit Gateway metrics can monitor some metrics (e.g., bytes in/out) but does not directly provide BGP session status.

Flow Logs capture IP traffic, not BGP routing information.
- ✓
AWS Transit Gateway Network Manager
Why this is correct
Network Manager provides a central dashboard for monitoring BGP sessions and connectivity.
- ✗
Amazon CloudWatch with Transit Gateway metrics
Why it's wrong here
CloudWatch metrics do not include BGP session status.
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.
