350-601 Compute Practice Question
A data center engineer is configuring VLANs in a Cisco UCS domain. Which TWO statements are true regarding VLAN configuration?
⚠ Common exam trap
Cisco often tests the misconception that VLANs can be created locally within a service profile or that the native VLAN is optional, when in fact it must be explicitly configured for each vNIC to handle untagged traffic correctly.
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
✓
Each vNIC must have a native VLAN specified for untagged traffic on that vNIC.
In a Cisco UCS environment, each vNIC must have a native VLAN specified to handle untagged traffic on that interface. The native VLAN is used for traffic that does not have an 802.1Q tag, and it must be explicitly defined in the vNIC configuration within the service profile to ensure proper handling of untagged frames.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VLANs can be created directly within a service profile without prior global definition.
Why it's wrong here
VLANs cannot be created in service profiles; they must reference existing global VLANs.
- ✗
VLANs can be created only through the CLI of UCS Manager.
Why it's wrong here
VLANs can be created via both GUI and CLI.
- ✗
Service profiles can override the VLAN ID of a global VLAN definition.
Why it's wrong here
Service profiles reference global VLANs, not override them.
- ✓
Each vNIC must have a native VLAN specified for untagged traffic on that vNIC.
Why this is correct
A native VLAN is required for untagged frames on a vNIC.
- ✓
VLANs must be defined in the global VLAN database before they can be used in a service profile.
Why this is correct
UCS requires VLANs to be defined globally before assignment to vNICs.
