Explanation

Answer B is correct: EPLD upgrades on Cisco MDS 9000 are performed module-by-module (rolling), so only the specific module being upgraded is disrupted while all other modules continue forwarding traffic. Answer E is correct: modules must be in the online state before they can be upgraded-offline or powered-down modules are skipped and cannot have their EPLDs programmed. Option A is incorrect because EPLD upgrades are initiated from the active supervisor, not the standby. Option C is incorrect because the active supervisor module cannot be upgraded using the standard rolling EPLD process without causing a supervisor switchover or reload. Option D is incorrect-if an upgrade is interrupted (e.g., connection loss), the upgrade does not automatically resume; the module may be left in an inconsistent state requiring manual intervention.
