Question 140
At the Brookfield transport facility, a finance workstation receives the guest subnet after moving to a newly configured CX access port. How should the organization sustain the improvement?
Explanation
Correct Answer
The needed prevention is to audit access VLAN mappings after workstation moves. It directly sustains the original change to set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. This result addresses the stated challenge at the Brookfield transport facility.
Incorrect Answers
different untagged VLAN handling can leak or misdeliver management and user frames. The offered alternative applies that mechanism: Validate trunk tagging assumptions during interface changes. The reported facts point to a different controlling condition: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The alternative does not directly settle the required recurrence control.
Retest traffic markings after endpoint software updates. Its technical scope is explained by: a configured policy may not match traffic or may be rewritten further along the path. In this question, the decisive issue is: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That is why the offered option is not the most direct recurrence control.
The option states: Validate peer parameters before routing policy deployments. The source describes its associated mechanism as: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. Choosing this alternative would leave the question’s specific recurrence control unresolved.
