   Compared to LAN-based backup, what is a key advantage of SAN-based backup?

   • AIt is always less expensive to implement
   • BIt requires no backup software
   • CIt reduces LAN congestion by using a separate network
   • DIt is simpler to configure than LAN-based backup

   A company has a SAN and a backup server connected to it. The tape library is also SAN-attached. The backup administrator is considering two topologies: LAN-free backup and server-free backup. The company has a limited budget but wants to minimize the load on the backup server. Which topology is the most appropriate?

   • ALAN-free backup: have the backup server read and write over the SAN.
   • BServer-free backup: use a data mover to copy data directly from the SAN to tape.
   • CSAN-based backup: use the backup server to manage the backup.
   • DDirect-attached backup: attach a tape drive directly to the backup server.

   What is a primary limitation of LAN-based backup topology?

   • AIt cannot support any backup software
   • BIt can saturate the production network during backup windows
   • CIt is only suitable for mainframe environments
   • DIt requires a dedicated storage area network

   A financial institution has a SAN with high-performance disk arrays. The backup administrator wants to perform backups without using the production servers' CPU or memory and without using the LAN. The backup software supports a data mover that can access the SAN. Which topology meets both requirements?

   • ADirect-attached backup: attach a tape drive to each server.
   • BLAN-free backup: the backup server reads data from the SAN and writes to tape.
   • CServer-free backup: the data mover reads data from the SAN and writes to a SAN-attached tape library.
   • DSAN-based backup: the backup server manages the backup and reads/writes over the SAN.

   A mid-sized company runs nightly backups of 20 application servers to a central backup server. The backup server writes to a tape library. Recently, backups have started exceeding the backup window, and network congestion during backup hours is affecting production traffic. Which change would most directly address both the backup window and the LAN congestion?

   • AMove the tape library to a SAN and configure the backup server to write backups over the SAN instead of the LAN.
   • BSwitch to a direct-attached backup topology by attaching a tape drive to each application server.
   • CUse server-free backup by deploying a data mover on each server to write directly to tape.
   • DIncrease the number of backup agents on each server to parallelize the backup streams.
