NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator configures inter-VDOM routing between VDOM-A and VDOM-B using a VDOM link. After configuration, traffic from VDOM-A cannot reach VDOM-B. Which configuration step is MOST likely missing?
⚠ Common exam trap
It's easy for candidates to assume static routes or a global inter-VDOM routing toggle are required, overlooking that VDOM links function like physical interfaces and need firewall policies to permit traffic.
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
✓
Create a firewall policy on VDOM-A and VDOM-B allowing traffic over the VDOM link interface
VDOM links are special inter-VDOM interfaces that require firewall policies on both VDOMs to permit traffic. Without a policy on VDOM-A and VDOM-B that allows traffic over the VDOM link interface, packets will be dropped by the implicit deny rule. This is the most common missing step when inter-VDOM routing fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a firewall policy on VDOM-A and VDOM-B allowing traffic over the VDOM link interface
Why this is correct
Each VDOM must have a policy allowing traffic to/from the VDOM link interface, similar to any other interface.
- ✗
Enable 'inter-vdom-routing' under system settings
Why it's wrong here
Inter-VDOM routing is enabled by default when VDOMs are enabled; the missing step is typically a policy.
- ✗
Configure a static route on VDOM-A pointing to VDOM-B's subnet via the VDOM link
Why it's wrong here
If the VDOM link is a point-to-point link, routes may be needed but policies are still required.
- ✗
Assign both VDOM link interfaces to the same VDOM
Why it's wrong here
The VDOM link has two ends, one in each VDOM; they are in different VDOMs by design.
