350-401 Practice Question: Which two statements about VRF-aware services are…
Which two statements about VRF-aware services are true? (Choose two.)
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
✓
VRF-lite allows multiple routing instances on a single router using separate routing tables.
VRF-aware services allow network functions to operate within the context of a specific VRF, enabling per-VRF routing and forwarding. Option A is correct because VRF-lite provides multiple routing instances on a single router by maintaining separate routing tables for each VRF, using either static or dynamic routing. Option B is correct because services like DHCP and NAT can be configured independently per VRF, allowing address translation and address assignment to be isolated per VRF. Option C is incorrect because VRF instances are not limited to MPLS VPN environments; they can be used in VRF-lite deployments without MPLS. Option D is incorrect because route leaking between VRFs is supported in Cisco IOS through manual configuration (e.g., route import/export) or using VRF-lite with route replication. Option E is incorrect because each VRF has its own routing table, separate from the global routing table; VRFs do not share a common global routing table.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VRF-lite allows multiple routing instances on a single router using separate routing tables.
Why this is correct
Correct because VRF-lite creates separate virtual routing and forwarding tables on a single device, enabling path isolation without MPLS.
- ✓
VRF-aware services such as DHCP and NAT can be configured independently per VRF.
Why this is correct
Correct because many Cisco IOS services are VRF-aware, allowing per-VRF DHCP pools, NAT rules, and other functions.
- ✗
VRF instances are only supported on routers running MPLS VPN.
Why it's wrong here
Incorrect because VRF-lite can be used without MPLS, using only IP routing and separate forwarding tables.
- ✗
Route leaking between VRFs is not supported in Cisco IOS.
Why it's wrong here
Incorrect because route leaking (e.g., using import/export route targets or static routes) is a common feature to allow controlled inter-VRF communication.
- ✗
All VRFs on a router must share the same global routing table.
Why it's wrong here
Incorrect because each VRF maintains its own independent routing table, separate from the global table.
