9.(Single Answer) Users of HuaweiStorageSystem A are requesting higher performance for their OLTP application. The OLTP
application is the only system using HuaweiStorageSystem A.
A colleague suggests improving performance by running SmartQOS on the LUNs involved, while decreasing the performance of other
services. This is;
     A.  Not a solution to the problem, the other services will no longer work correctly.
     B.  A solution, but not the best solution; SmartPartition would be better.
     C.  A good solution for the problem; performance will improve.
     D.  Not a solution for the problem, since there will be only one queue of I/O.

10.(Single Answer) Application Server X needs to access data on StorageSystem X with multipathing software X and data on third-party StorageSystem Y with multipathing software Y. The combination of multipathing software is generating errors. A colleague suggests using SmartVirtualization to represent the data on third-party StorageSystem Y in an eDevLUN on StorageSystem X. This is:
     A.  Not a solution to the problem, the multipathing software X will now generate errors.
     B.  Not a solution to the problem, the data still resides on StorageSystem Y.
     C.  A solution to the problem, we can remove the multipathing software Y once the eDevLUN is available.
     D.  A solution to the problem, but only if we disable StorageSystemY once the eDevLUN is available.
