Explanation
In SmartFabric mode on the Dell EMC MX7000, 512 VLANs per server port is the recommended maximum - option B. This limit is a design constraint of SmartFabric's automated fabric management, which optimizes for stability and manageability rather than raw VLAN scale.
Why the distractors are wrong:
- A (256) is too low - it undersells SmartFabric's actual capacity and reflects no specific documented limit.
- C (1024) and D (1536) exceed the recommended maximum; while total VLAN ranges can go higher in other contexts, pushing beyond 512 per server port in SmartFabric mode risks instability and is not supported by Dell's best-practice guidance.
Memory tip: Think "5-1-2 = SmartFabric's fine line" - 512 is the sweet spot that keeps fabric automation reliable. If you see anything above 512 for per-port VLANs in SmartFabric mode, it's beyond the recommended boundary.
