The correct answer is C. Enable PIM active-active feature on both Agg-1 and Agg-2. In a VSX environment, only one aggregation switch (Agg-1) is the PIM-SM Designated Router (DR) and IGMP querier. During an upgrade, when Agg-1 is unavailable, multicast traffic forwarding fails until Agg-2 takes over. By enabling the PIM active-active feature on both Agg-1 and…

Explanation
In a VSX environment, only one aggregation switch (Agg-1) is the PIM-SM Designated Router (DR) and IGMP querier. During an upgrade, when Agg-1 is unavailable, multicast traffic forwarding fails until Agg-2 takes over. By enabling the PIM active-active feature on both Agg-1 and Agg-2, multicast forwarding becomes synchronized and seamless across both devices, reducing downtime to the minimum.
