Which two are true with respect to the upgrade process for the Cisco Unified Computing System? (Choose two.)
A. For easier manageability, Cisco provides one full bundle that contains the firmware images for all Cisco Unified Computing System components.
B. You can choose from FTP, TFTP, SCP, and HTTP to copy the bundle image from a remote file system.
C. When the bundle image is downloaded, it must be transferred to the flash file system of the active fabric interconnect.
D. When the download is successful, Cisco Unified Computing System Manager expands the individual files from the archive and installs them in the correct flash file system partition.
E. It is strongly recommended that you activate all components in all chassis at one time.
F. The I/O module, CIMC, and adaptors update process operates strictly on the backup partition of Flash for a given component.
It should be B and C because there is an option when you copying the bundle image to the fabric interconnects that allows you to choose whether a local file system or remote file system you want to copy the bundle image from.
