Dell EMC Specialist – Implementation Engineer, ECS — Question 35

You have just upgraded a VxRail Cluster from version 4.5.x to version 4.7.x. You need to ensure that new VxRail 4.7.x nodes will be discovered without having to make any changes to the nodes.
What action should you take on the existing configuration?

Answer options

• A. Add a new VLAN to the ToR switches with ID 3939 In vCenter, set the VLAN ID of the Management Network distributed portgroup to 3939
• B. In vCenter, set the VLAN ID of the Management Network distributed portgroup to 3939
• C. Add a new VLAN to the ToR switches with ID 3939 In vCenter, set the VLAN ID of the VxRail Management distributed portgroup to 3939
• D. Add a new VLAN to the ToR switches with ID 3939

Correct answer: A

Explanation

The correct answer is A because it involves both adding a VLAN to the ToR switches and configuring the Management Network distributed portgroup in vCenter, which is necessary for the new nodes to be discovered correctly. Option B only modifies the VLAN ID in vCenter without adding the required VLAN to the switches, while option C incorrectly references the VxRail Management portgroup, and option D fails to set the VLAN ID in vCenter, making them insufficient for the task.
