   A large enterprise has a SAN with multiple database servers. The backup administrator wants to minimize the impact of backups on the database servers' CPU and memory. The backup software supports a data mover appliance that can read data directly from the SAN and write to a SAN-attached tape library. Which topology should be used?

   • ASAN-based backup: connect the tape library to the SAN and have the backup server manage the backup.
   • BDirect-attached backup: attach a tape drive to each database server.
   • CServer-free backup: use the data mover to copy data from the database LUNs to tape without involving the database servers or a backup server.
   • DLAN-free backup: have the backup server read the LUNs and write to tape over the SAN.

   A company is evaluating backup topologies. They have a fast 10 Gbps LAN and a limited budget. They have a single backup server and a tape library. Which topology is the most appropriate?

   • ALAN-based backup: use the fast LAN to move backup data to the backup server.
   • BServer-free backup: deploy data movers to offload servers.
   • CLAN-free backup: use a SAN to avoid LAN traffic.
   • DSAN-based backup: invest in a SAN to offload backup traffic from the LAN.

   A small business has one server with a directly attached tape drive. The backup software runs on the same server and writes backups to the tape drive. What is the primary limitation of this topology?

   • AIt requires a SAN to function.
   • BIt is the most complex topology to implement.
   • CIt does not scale well to back up multiple servers without adding network-based backup.
   • DIt cannot use tape media.
