JNCIA-SEC Srx Series Service Gateways Practice Question
An administrator sets up a virtual router routing instance on an SRX Series device to isolate customer traffic. How do security policies interact with traffic passing between different routing instances or security zones within virtual routers?
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
✓
Security policies continue to be enforced based on security zone membership, and inter-zone traffic requires explicit policy rules regardless of virtual router boundaries.
Security policies on SRX devices are bound to security zones, and zones can span virtual routers or be assigned per routing instance depending on configuration, requiring explicit inter-zone policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Security policies automatically permit all traffic between virtual routers.
Why it's wrong here
Virtual routers still require security policies if traffic passes between security zones.
- ✓
Security policies continue to be enforced based on security zone membership, and inter-zone traffic requires explicit policy rules regardless of virtual router boundaries.
Why this is correct
Security policies are enforced between security zones across the SRX, and routing instance isolation interacts with zones and logical interfaces.
- ✗
Virtual routers replace security zones entirely.
Why it's wrong here
Virtual routers handle layer 3 routing separation, while security zones handle layer 3/4 security boundaries.
- ✗
Security policies are bypassed when virtual routers are used.
Why it's wrong here
Virtual routers do not bypass stateful security policies.
