350-701 Practice Question: An engineer is designing a cloud security…
An engineer is designing a cloud security solution using Cisco SD-WAN with cloud on-ramp. They want to ensure that traffic to a specific IaaS provider is inspected by the Cisco Umbrella SIG. Which configuration is necessary on the SD-WAN edge?
⚠ Common exam trap
Cisco often tests the distinction between DNS-layer security (Umbrella DNS) and full proxy-based SIG inspection; candidates mistakenly think DNS security alone provides the same traffic inspection as a service insertion policy.

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
✓
Configure a service insertion policy for the cloud security provider
To direct specific traffic to Cisco Umbrella SIG for cloud security inspection, you must configure a service insertion policy on the SD-WAN edge. This policy intercepts traffic based on match criteria (e.g., destination IaaS provider IP/subnet) and forwards it to the cloud security service via a secure tunnel (e.g., IPsec or TLS). Without this policy, the SD-WAN edge will not redirect traffic to Umbrella for inspection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a service insertion policy for the cloud security provider
Why this is correct
Service insertion redirects traffic to the cloud security service for inspection.
- ✗
Apply a DNS security policy
Why it's wrong here
DNS security only blocks malicious domains, not full traffic inspection.
- ✗
Set up a site-to-site VPN to the IaaS
Why it's wrong here
VPN only provides encrypted connectivity, not security inspection.
- ✗
Enable direct internet access for the branch
Why it's wrong here
Direct internet access would bypass the security inspection.

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.
