• Question 217:

  An organization uses Linux desktops, laptops, and servers for their primary infrastructure. The company has a business need to run a mission critical application that is only available for the Microsoft Windows operating system. This application and associated data need to be available to 10-12 users.

  Which solution would best meet their needs, and why?

  A. VDI, because it provides better fault tolerance
  B. VDI, because it offers a lower cost per user than
  C. RDS, because it offers true user segmentation

• Question 218:

  Which product performs virtualized data caching across heterogeneous storage arrays?

  A. VMAX
  B. VNX
  C. VPLEX
  D. Atmos
  C. VPLEX

• Question 219:

  You are meeting with the CIO to discuss your VDC design. They question the amount of capital that is being invested in iSCSI adapters. They state that, because of the number of adapters required, it is more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.

  How should you justify the increased cost of the iSCSI Adapters?

  A. Using NICs and the software stack will increase CPU load on each hypervisor, requiring more hypervisors to deliver the same performance levels. This will result in additional hardware and licensing costs.
  B. iSCSI adapters can encrypt iSCSI frames, preventing unauthorized access to the data. The hypervisor software stack cannot encrypt iSCSI frames, leaving the data vulnerable.
  C. Using NICs and the software stack will require additional NICs for each hypervisor to deliver the same throughput. To obtain the additional PCIe slots for the NICs, larger form- factor servers will be required, increasing hardware costs.
  D. iSCSI adapters can use Jumbo Frames, providing improved performance for storage traffic. The hypervisor software stack cannot use Jumbo Frames, resulting in poorer performance.
  A. Using NICs and the software stack will increase CPU load on each hypervisor, requiring more hypervisors to deliver the same performance levels. This will result in additional hardware and licensing costs.

• Question 220:

  A company intends to convert their VDC to IaaS. To do this they will have to implement several new technologies and create new functions for service

  operations and service management. The company previously claimed to be service oriented because they had a service desk in IT to provide support.

  What is

  required for a successful transition to IaaS?

  A. A chargeback/showback method for showing value back to the business
  B. ITIL-based, standardized service templates
  C. An expanded help desk that includes more comprehensive reporting
  D. Service level agreements with the lines of business
  A. A chargeback/showback method for showing value back to the business
