The correct configuration is to create separate VLAN pools for each fabric with non-overlapping ranges, as this directly supports assigning a unique native VLAN ID per fabric interconnect in UCS Manager. This works because UCS Manager allows VLAN pools to be assigned independently to each fabric interconnect, so by using non-overlapping ranges, you ensure that the native VLAN ID on Fabric A never conflicts with the native VLAN ID on Fabric B, enabling true VLAN segmentation across multiple fabrics. On the Cisco DCCOR 350-601 exam, this concept tests your understanding of UCS Manager’s fabric-level resource management, often appearing in scenario-based questions where you must choose between a shared pool and separate pools—a common trap is assuming a single pool can serve both fabrics with different native VLANs, which is incorrect. Remember the memory tip: “Separate pools, separate fabrics, no VLAN conflicts.”
350-601 Compute Practice Question
This 350-601 practice question tests your understanding of compute. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data center engineer is designing a UCS Manager solution that requires VLAN segmentation across multiple fabric interconnects. The network team requires that each VLAN is assigned a unique native VLAN ID per fabric. Which pool configuration supports this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create separate VLAN pools for each fabric with non-overlapping ranges
Option B is correct because UCS Manager allows separate VLAN pools to be assigned per fabric interconnect, enabling unique native VLANIDs per fabric. By creating non-overlapping VLAN pools for each fabric, the engineer ensures that each fabric has its own native VLAN ID without conflict, meeting the requirement for VLAN segmentation across multiple fabric interconnects.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use derived VLAN pools based on chassis location
Why it's wrong here
Derived pools are not a UCS construct
✓
Create separate VLAN pools for each fabric with non-overlapping ranges
Read the scenario before looking for a memorised answer.
✗
Create a single VLAN pool that includes all required VLANs
Why it's wrong here
Single pool does not allow per-fabric uniqueness
✗
Configure VLANs directly in the service profile using inline pools
Why it's wrong here
Inline pools are used for MAC/WWN, not VLANs
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that a single VLAN pool can be used for both fabrics, but the requirement for unique native VLANIDs per fabric demands separate pools with non-overlapping ranges to avoid conflict.
Detailed technical explanation
How to think about this question
In UCS Manager, VLAN pools are assigned to fabric interconnects via LAN uplink policies or VLAN groups, and each fabric can have its own pool with distinct native VLANIDs. This is critical in multi-fabric designs where each fabric must have a unique native VLAN to avoid Layer 2 loops or misconfigurations, especially when using protocols like VPC or vPC+. The native VLAN ID is typically configured in the VLAN pool properties, and non-overlapping ranges ensure no VLAN ID collision between fabrics.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
