Which two actions should be performed before upgrading the infrastructure and firmware of multiple UCS blades? (Choose two)

Question

Options

• AVerify if the bootflash on the fabric interconnects in the Cisco UCS has at least 15% available
• BEnable Smart Call Home feature during the firmware upgrade process
• CVerify if the bootflash on the fabric interconnects in the Cisco UCS has at least 10% available
• DRun the Check Conformance feature to verify that all your components are running the
• EGet Full State and All Configuration backup files before beginning the upgrade

• A
  6% (1)
• B
  11% (2)
• D
  83% (15)

Explanation

Before upgrading UCS blade infrastructure and firmware, two critical pre-upgrade steps are required. First (D), running the 'Check Conformance' feature verifies that all components-IOMs, adapters, BIOS, CIMC-are running firmware versions that are compatible and consistent with the current software bundle, identifying any out-of-conformance components before the upgrade begins. Second (E), obtaining Full State and All Configuration backup files ensures that the entire UCS domain configuration can be restored if the upgrade fails or causes issues. Verifying bootflash space (options A/C) is a valid concern but the commonly cited threshold and the primary documented pre-upgrade steps for multiple blades are conformance checking and backup.
