Which two statements are false about backup to ZFS Storage Appliance (ZFSSA)?

A. ZFS Snapshots can provide rapid cloning of development and test environment.
B. Top of Rack (ToR) switches are managed as part of the hardware stack and software levels are upgraded during the patching process.
C. When backing up multi-rack systems, sharing Exadata X9M switches is recommended.
D. ZFSSA may connect directly to the Exadata 100Gb RoCE network switches.
