1Z0-997-26 Multicloud And Hybrid Practice Question
Your security team requires that all data traversing the OCI-Azure Interconnect must be encrypted. Does the standard OCI-Azure Interconnect encrypt traffic natively at Layer 3?
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
✓
No, native interconnect traffic is unencrypted; you must layer IPsec VPN over the interconnect if encryption is mandatory.
The OCI-Azure Interconnect uses dedicated Layer 2/Layer 3 circuits (ExpressRoute to FastConnect) which do not natively encrypt data in transit; customers must implement overlay encryption (like IPsec VPN) if encryption is required.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Yes, Oracle and Microsoft automatically handle TLS 1.3 encryption for all packets.
Why it's wrong here
TLS is an application-layer protocol and is not automatically applied to all network traffic.
- ✗
Yes, all traffic is encrypted using MACsec by default.
Why it's wrong here
MACsec is not enabled by default on standard interconnect circuits.
- ✓
No, native interconnect traffic is unencrypted; you must layer IPsec VPN over the interconnect if encryption is mandatory.
Why this is correct
Interconnect circuits do not provide native encryption; an IPsec tunnel must be built on top if encryption is required.
- ✗
No, and encryption is strictly prohibited by Oracle security policies.
Why it's wrong here
Customers are encouraged to apply encryption over hybrid links when required.
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.
