Which two actions should be performed before upgrading the infrastructure and firmware of multiple UCS blades? (Choose two.)
Before upgrading the infrastructure and firmware of multiple UCS blades, it is crucial to ensure system stability and compatibility. First, getting Full State and All Configuration backup files is essential to maintain a recovery point in case of any issues during the upgrade. Second, verifying if the bootflash on the fabric interconnects in the Cisco UCS has at least 15% available space is important to ensure there is adequate room for the upgrade process, which may involve temporary storage needs exceeding lower thresholds.
It should be A&B
D => incorrect E => it is important but after upgrade B & C either could be correct, checking for available space is important, 15% is the more appropriate threshold compared to 10%
Will go for A, B. Question states: do stuff before. E is after upgrade procedure. Smartl call home should be disabled. This leaves us with two options: B,C. B is logically more suited, because of 90% raises faults in UCSM
As per the document below, "when the bootflash partition exceeds 70 percent, faults are raised". It also mentions we should have at least 20% available space, otherwise Auto Install will not proceed. https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI-User-Guides/Firmware-Mgmt/4-2/b_UCSM_GUI_Firmware_Management_Guide_4-2/b_UCSM_GUI_Firmware_Management_Guide_chapter_010.html
