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
✓
Virtual Cloud Networks (VCNs)
DRG version 2 supports attachments to VCNs, Site-to-Site VPN IPSec connections, FastConnect virtual circuits, and remote peer DRGs for cross-region peering.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Virtual Cloud Networks (VCNs)
Why this is correct
VCN attachments allow the DRG to route traffic to and from cloud networks.
- ✗
Internet Gateways
Why it's wrong here
Internet Gateways attach directly to VCNs, not to DRGs.
- ✗
Local Peering Gateways (LPGs)
Why it's wrong here
LPGs are used for same-region VCN peering without a DRG (or via legacy architecture), whereas DRGs replace LPGs in modern hub-and-spoke architectures.
- ✓
IPSec VPN tunnels
Why this is correct
Site-to-Site VPN connections attach to the DRG.
- ✓
FastConnect virtual circuits
Why this is correct
FastConnect virtual circuits terminate on the DRG.
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.
