200-150 · Question #75
Which two statements are true regarding disruptive load balancing and regarding the configuration In this example? (Choose two)
The correct answer is B. In this scenario disruptive load balancing is enabled. D. When disruptive load balancing is enabled, NPV redistributes the server interfaces across all. When NPV disruptive load balancing is enabled, the switch actively redistributes server interfaces across all available NP uplinks, which may briefly interrupt active I/O.
Question
Which two statements are true regarding disruptive load balancing and regarding the configuration In this example? (Choose two)
Options
- AIn this scenario disruptive load balancing is disabled.
- BIn this scenario disruptive load balancing is enabled.
- CSince FCID: 0x1 c0000 is reserved, disruptive load balancing is not configured correctly.
- DWhen disruptive load balancing is enabled, NPV redistributes the server interfaces across all

Why each option
When NPV disruptive load balancing is enabled, the switch actively redistributes server interfaces across all available NP uplinks, which may briefly interrupt active I/O.
Disruptive load balancing is not disabled in this configuration; the relevant command is present and active, making this statement factually incorrect.
The configuration shown has the NPV disruptive load balancing feature active, meaning the switch will rebalance server F-port assignments across uplinks when triggered, confirming that disruptive load balancing is enabled.
FCID 0x1c0000 being a reserved value is unrelated to the correctness of the NPV load-balancing configuration; the feature operates independently of specific FCID assignments.
When disruptive load balancing is enabled, the NPV switch redistributes server (F-port) interfaces across all available NP uplink ports to achieve improved load distribution, potentially causing a brief traffic disruption during the rebalancing event.
