Which two features are implemented using Brocade IronStack technology? (Choose two.)
The correct answer is C. You can manage multiple physical switches in an IronStack as a single logical switch. D. You can perform a hitless stack failover without impacting Layer 2 and Layer 3 unicast traffic. See the full explanation below for the reasoning.

Carlos M.Jun 11, 2026C and D are your answers. IronStack lets you manage a stack of physical switches as one logical unit (single management IP, unified config), and it supports hitless failover so traffic keeps flowing without interruption when the active unit goes down.
Fatima Z.Jun 16, 2026A is bait, but CD never skips traffic: pick C, D.
Haruki E.Jun 22, 2026Saw this exact question on my 150-130 sitting last year and eliminated A immediately because IronStack requires dedicated stacking ports, not arbitrary ports, and tossed B because image mismatches break stack formation entirely, which left C and D standing on their own since single logical switch management and hitless failover for both L2 and L3 unicast are the two pillars Brocade built the whole IronStack value proposition around.
Carlos M.Jun 22, 2026Solid breakdown, though worth flagging that hitless failover on L3 unicast specifically requires the standby unit to have already synced the forwarding table, so it is really a precondition more than a standalone feature in the exam context.
