NS0-157 · Question #40
You have two LIFs homed on the same single-mode interface group. You want to leverage both 10 Gb interfaces as active/active. What must you do to use both 10 Gb interfaces?
The correct answer is B. Delete the interface group, and home each LIF to one port each. A single-mode interface group keeps only one physical port active at a time, so two LIFs in the same single-mode ifgrp cannot simultaneously use both 10Gb links. The only way to achieve true active/active throughput is to remove the interface group and bind each LIF to its own…
Question

Options
- AMove one of the LIFs to another node in the cluster.
- BDelete the interface group, and home each LIF to one port each.
- CCreate another single-mode interface group and move one LIF to it.
- DChange the ifgrp distribution function from the default IP setting to MAC.

Why each option
A single-mode interface group keeps only one physical port active at a time, so two LIFs in the same single-mode ifgrp cannot simultaneously use both 10Gb links. The only way to achieve true active/active throughput is to remove the interface group and bind each LIF to its own dedicated port.
Moving a LIF to another node spreads load across nodes but does not resolve the single-mode constraint on the original node, and introduces unnecessary topology changes.
Single-mode interface groups operate as a failover pair - only the primary port forwards traffic while the secondary remains idle, making active/active bandwidth sharing impossible within the same group. Deleting the interface group and homing each LIF to a separate physical 10Gb port allows both ports to carry traffic concurrently, fully utilizing the available bandwidth.
Creating a second single-mode interface group still leaves each group with only one active port at a time, so neither group achieves active/active use of both physical interfaces.
The distribution function (IP vs. MAC) controls outbound packet hashing in multi-mode interface groups and has no effect on single-mode ifgrps, which cannot activate both ports simultaneously regardless of this setting.
