1Z0-1072-26 Networking Practice Question
Your company requires a dedicated, highly reliable, encrypted connection from your on-premises datacenter to your OCI Virtual Cloud Network, bypassing the public internet entirely. The link must support speeds up to 10 Gbps and provide failover redundancy. Which OCI service meets this requirement?
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
✓
FastConnect with MACsec or layered IPsec VPN
FastConnect provides a dedicated, private connection between your datacenter and OCI. For encryption across FastConnect, you can layer an IPsec VPN over the FastConnect circuit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Oracle Cloud Infrastructure Public Load Balancer with SSL termination
Why it's wrong here
A Load Balancer distributes web traffic and does not connect on-premises datacenters to VCNs.
- ✓
FastConnect with MACsec or layered IPsec VPN
Why this is correct
FastConnect provides dedicated private connectivity, and data can be encrypted using MACsec or by layering an IPsec VPN over FastConnect.
- ✗
Site-to-Site VPN over Public Internet
Why it's wrong here
Site-to-Site VPN uses the public internet, which does not fulfill the requirement of bypassing the public internet.
- ✗
Remote Peering Connection (RPC)
Why it's wrong here
An RPC is used to peer two VCNs across different regions, not for connecting an on-premises datacenter.
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.
