A Maintenance Window Had Been Scheduled to Allow for the Upgrade

A maintenance window had been scheduled to allow for the upgrade of the firmware of one of the VSP switches in the ACP. However, steps were not taken to avoid receiving unnecessary notifications during this period. As a result, when the upgrade process started the VSP switch shows multiple critical alerts. At this point, what would a support engineer do to reduce the amount of these unwanted alerts?

A) Use the Post-Event Downtime feature in Orchestrator.
B) Use the Mass Acknowledgments feature in Orchestrator.
C) Use the Recurring Downtime feature in Orchestrator.
D) The engineer will have to wait for the upgrade process to complete.
