IBM C4090-452 Online Questions & Answers

• Question 41:

  A customer is planning for deployment of a new Storwize V7000 and has identified interest in leveraging EC0E and 10 GbE. Identify one requirement that will be part of the configuration setup and should be reviewed with the customer.

  A. Ensure that FC0E switch to which the 10 GbE ports are connected is configured in NPV mode.
  B. Inter node communication between two FCOE ports in the same I/O group should not cross ISL5.
  C. Connect 10 GbE ports on Storwize V7000 only to the CEE network that supports the DCBX protocol (802.1QBG).
  D. Each Storwize V7000 10 GbE FCoE port should have at least two paths to all other Storwize V7000 nodes that are part of the same clustered system.
  B. Inter node communication between two FCOE ports in the same I/O group should not cross ISL5.

• Question 42:

  A customer needs a new midrange disk system for their iSCSI-only environment. The Storwize V7000 meets all their requirements except that they are concerned that there may not be enough bandwidth available from the iSCSI ports on the Storwize V7000 control enclosure to meet the performance requirements.

  What should be proposed to meet the customer needs?

  A. IBM DS5020
  B. IBM Storwize V7000 with 10Gb SCSI
  C. IBM Storwize V7000 with 2 control enclosures
  D. IBM Storwize V7000 with external storage license
  B. IBM Storwize V7000 with 10Gb SCSI

• Question 43:

  A customer has stated a particular set of host data will take a maximum of 30 days to migrate to a Storwize V7000 from a DS4700 storage array. The data is spread across only two of the four total disk enclosures of the DS4700.

  What is the appropriate number of external virtualization licenses to order?

  B. 2
  C. 4
  D. 5
  A

• Question 44:

  The customer requires a solution with EC and CIES support. They need 20 TB high performance capacity for block data and 5 TB capacity for file data. What would be the most cost effective solution to meet the customer requirements?

  A. SONAS
  B. Storwize V7000 Unified
  C. Storwize V3700 Unified
  D. Storwize V7000 and DCS3700

• Question 45:

  A Storwize V7000 customer's requirements dictate automated intelligent data placement and physical disk redundancy are critical, and overall cost is a critical decision point. The environment is a 98% read workload. Which solution meets these requirements?

  A. Configure one storage pool of SSD5 and a second storage pool of SAS drives
  B. Design two multi-tiered storage pools composed of SSD and SAS which utilize SSD5 with Easy Tier
  C. Provide a single multi-tiered storage pool composed of SSD and SAS with only enough SSDs for 5% of the required storage capacity
  D. Utilize Easy Tier with SSD5 in one multi-tiered storage pool composed of SSD and SAS, and a single NL-SAS tier in a second storage pool
  C. Provide a single multi-tiered storage pool composed of SSD and SAS with only enough SSDs for 5% of the required storage capacity

• Question 46:

  Which statement best describes a difference in replication on the Storwize V7000 Unified between the block volumes and the file volumes?

  A. Both block and file volumes require Metro/Global Mirror licenses.
  B. Block volumes can replicate over the Ethernet ports or Fibre ports.
  C. File volumes must replicate through the block portion of the system.
  D. File volumes replicate over the Ethernet ports without the use of a SAN router.
  D. File volumes replicate over the Ethernet ports without the use of a SAN router.

• Question 47:
