The engineer has staged the new image with 'install add file flash:cat9k_iosxe.17.06.01.SPA.bin'. The engineer then runs 'install activate'. The activation fails with an error. What is the most likely cause of the failure?

   • AThe switch is not connected to the network, so the image could not be downloaded.
   • BThe engineer did not run 'install commit' before 'install activate'.
