Which action would you perform next?
A server has lost half of its paths to its LUN on a storage system. The help desk determines that
one of the two HBAs was just replaced. The SAN administrator has modified the zoning with the
new WWPN of the replacement HBA port, but the missing paths have still not recovered.

What is the most probably cause for the large read pending at the host?
A four-way cluster is attached to two fabrics. Each member has two HBAs connected to each fabric.
Each fabric has two subsystem connections. Each cluster member is a primary for one application. All
LUNs appear on all storage ports with workload equally distributed across all. Each host has two
dedicated HBAs for tape that can each see four independent LTO II (35MB/s) tape drives. All files are
large and involve sequential I/O. Performance reporting shows a large read pending at the host
during multi-threaded backup. What is the most probably cause for the large read pending at the host?

What is table routing?
A customer has a SAS-based storage environment with a SAS domain and some standalone servers,
each with multiple built-in SAS disks. The implementation includes direct routing, table routing and
subtractive routing. What is table routing?

Which type of replication should the company use to replicate the data?
A company needs to replicate a database from its main office to a disaster recovery site 3,000 km
away with a five minute recovery point objective.

What is the minimum amount of down-time possible?
A cluster is experiencing performance problems. An application running in parallel mode is being
migrated to a new cluster member. The cluster member is added, the application is installed,
zoning and LUN masking changes are made, and the application is brought up on the new cluster
member. What is the minimum amount of down-time possible?
What is the most likely cause?
You have recently upgraded a tape drive on a older switch to operate at 120MB/s from 80MB/s.
Prior to purchasing the tape drives, you tested server dumps to a disk array across multiple ports
and saw speeds exceeding 150MB/s. With the new tape drive, you have not seen any dump speed
exceed 100MB/s. What is the most likely cause?
