350-501 Services Practice Question
A service provider wants to provide Internet access to an MPLS L3VPN customer without leaking the Internet route into the VRF. Which feature allows the PE to forward traffic from the VRF to the global routing table?
⚠ Common exam trap
Cisco often tests the misconception that route leaking (Option B) is the only way to forward traffic between VRF and global tables, but the question explicitly prohibits leaking Internet routes, making VRF-aware NAT the correct answer because it provides forwarding without route injection.

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
✓
NAT with VRF awareness
NAT with VRF awareness (also known as VRF-aware NAT) allows the PE router to translate the private source IP address of traffic from the VRF to a public IP address in the global routing table, enabling Internet access without injecting Internet routes into the VRF. This feature performs NAT at the VRF-to-global boundary, forwarding traffic from the VRF to the global table while keeping the routing domains separate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Static default route from VRF to global
Why it's wrong here
A static route could direct traffic but without NAT the return traffic won't know VRF.
- ✗
Route leaking between VRF and global
Why it's wrong here
Leaking routes would expose the global table to the customer.
- ✗
VRF-Aware Firewall
Why it's wrong here
Not a standard Cisco feature for this purpose.
- ✓
NAT with VRF awareness
Why this is correct
NAT translates VRF source IP to global IP and route via global table.
