Question #11
The users within a department require a shared folder on their Windows desktop.
Which protocol accomplishes this requirement?
  1. A
    GPFS
  2. B
    CIFS
  3. C
    NFS
  4. D
    HTTPS

Correct Answer:
B
You can connect to a CIFS share using a CIFS client, such as Microsoft Windows.
The Common Internet File System (CIFS) is the standard way that computer users share files across corporate intranets and the Internet. An enhanced version of the Microsoft open, cross-platform Server Message Block (SMB) protocol, CIFS is a native file-sharing protocol in Windows.

Question #12
A NetApp customer has been concerned about the fragmentation of its system. The customer is considering moving to an IBM Storwize solution.
What does the IBM Storwize Family use as the foundational file system for file sharing?
  1. A
    HDFS
  2. B
    SMB
  3. C
    GPFS
  4. D
    NFS

Correct Answer:
C
Shares and exports can be managed through the GUI or CLI by Storwize V7000 Unified administrative users that have a user role definition that is authorized to perform share and export management functions.
A share or export results from making a disk space accessible through the protocols specified during its creation. HTTP, SCP, FTP, CIFS and NFS shares and exports can be created, provided that the corresponding protocol is enabled for the system. Shares and exports can only be created for data that is stored in the
GPFS file system of the Storwize V7000 Unified system. Non-GPFS file system content cannot be shared or exported.

Question #13
A customer has an Oracle RAC environment that requires high availability and disaster recovery in one solution.
Which feature of IBM Spectrum Virtualize addresses these needs?
  1. A
    FlashCopy
  2. B
    HyperScale
  3. C
    HyperSwap
  4. D
    Volume Migration

Correct Answer:
A
IBM Spectrum Protect Snapshot uses the FlashCopy or snapshot function of the storage solutions for database cloning. This method eliminates downtime and minimizes the impact on the production database.
After you share the FlashCopy repository, configuration and binary files, an Oracle RAC database clone can be created from every node of the Oracle RAC cluster. IBM Spectrum Protect Snapshot can operate on the clone from all RAC nodes, so that a clone created on one RAC node can be inquired, refreshed, or deleted from any other node within the RAC cluster.

Question #14
A company has added a second control enclosure to an IBM Storwize V7000 to provide more storage for several servers.
What must be done to the host systems before mapping volumes from the new I/O group?
  1. A
    Ensure the host zoning is in place for the new I/O group
  2. B
    Double the queue depth on each volume
  3. C
    Verify host mirroring is in place for the volumes
  4. D
    Install additional HBAs for connectivity to the new I/O group

Correct Answer:
A
The number of paths to a volume from a host to the nodes in the I/O Group that owns the volume must not exceed eight, even if eight is not the maximum number of paths supported by the multipath driver (SDD supports up to 32). To restrict the number of paths to a host volume, the fabrics must be zoned so that each host
FC port is zoned to no more than two ports from each Storwize V7000 Gen2 node in the I/O Group that owns the volume.

Question #15
A customer is deploying an IBM Storwize V7000 and wants to grow the system to 32 PB of addressable space.
Which extent size is needed to meet this requirement?
  1. A
    8192 MB
  2. B
    4096 MB
  3. C
    2048 MB
  4. D
    1024 MB

Correct Answer:
A
