   A data center team must upgrade the NX-OS software on a pair of Nexus 9000 switches that form an vPC domain. The switches are actively carrying production traffic for a financial trading platform, and the change window is limited to 30 minutes. The team has verified that the new NX-OS release supports ISSU (In-Service Software Upgrade) for the current configuration. Which approach best meets the requirement to minimize traffic disruption during the upgrade?

   • AUpgrade only one switch and leave the other on the old version permanently to avoid any disruption.
   • BUpgrade both switches simultaneously during the maintenance window, accepting a brief traffic outage.
   • CUpgrade one switch at a time using ISSU, verifying each switch returns to a stable state before proceeding to the next.
   • DPerform a disruptive upgrade on the primary vPC switch first, then the secondary, without using ISSU.
