A. licenses that are in the wrong network
B. more hardware devices than device licenses
C. expired device license
D. licenses that do not match the serial numbers in the organization
E. MR licenses that do not match the MR models in the organization
Explanation:
More hardware devices than device licenses: An organization needs to have enough device licenses to cover all the hardware devices in its network. A device license is consumed by each device that is added to the network. If the number of devices exceeds the number of licenses, the organization will be out of license and will lose access to some features and support until it purchases more licenses or removes some devices4.
Expired device license: A device license has an expiration date that depends on the license term purchased by the organization. If a device license expires, it will no longer be valid and will not count towards the license limit. The organization will need to renew the expired license or purchase a new one to avoid being out of license4.
