Which of the following scenarios accurately demonstrate how the Cisco Unified Computing
System ensures that a firmware upgrade is minimally disruptive to the data center unified fabric?
A.
If an I/O module is upgraded to a version that is incompatible with its fabric interconnect, the
fabric interconnect can automatically reactivate the I/O module to a compatible version.
B.
If components like server BIOS, HBA, and RAID controller firmware are unsuccessfully updated
through direct firmware updates, the update process will fall back to a host firmware package that
is associated with the service profile.
C.
If an update of the subordinate fabric interconnect leaves it in a nonusable state, the primary
fabric interconnect will automatically be updated to ensure that one fabric interconnect is running
the most recent firmware.
D.
After Cisco Unified Computing System Manager upgrades the subordinate node, only then is
the active management node automatically synchronized.
The Cisco UCS Manager GUI does not allow you to choose options that a release does not support. If a Cisco UCS domain includes hardware that is not supported in the release to which you are upgrading. Cisco UCS Manager GUI does not display the firmware as an option for that hardware or allow a user to upgrade to it
When upgrading firmware directly to an endpoint such as a IO module the system carries out a compatibility check unless the user checks the ignore compatibility check options
When firmware is activated the endpoint is rebooted and the new firmware becomes the active kernel version and system version. If the endpoint cannot boot from the new startup version firmware it defaults to the backup version and raises a fault
The backup version is the previous version of the firmware that was being replaced and as such was a working version
Option A is consider correct here
Upgrades of a Cisco IMC instance through a management firmware package or and adapter firmware package in the service profile that is associated with the server takes precedent over a direct firmware upgrades. You cannot directly upgrade endpoints if the services profile associated with the server includes a firmware package so answer b is incorrect
