• Question 239:

  Refer to the exhibit.

  

  A VDC design requires 300 blade server chassis, each with two embedded Fibre Channel switches, which are connected to two separate SAN fabrics. All of the blade chassis FC switches are configured in NPV mode, and the SAN core switches are configured in NPIV mode.

• Question 240:

  A midsize company has deployed centralized storage and is currently planning to virtualize their servers. They have considered their application into Tiers, with Tier 1 application requiring the same service and performance levels of the

  current servers.

  They have purchased new, high capacity servers for the virtualized environment and are planning to consolidate several physical servers into a single hypervisor. They are know determining the bandwidth requirements of the application in

  order to purchase the current number of FCME CNAs for each server.

  The results of their analysis for Tier 1 application are as follows:

  Average SAN Bandwidth: 3 Gb/s

  Average LAN Bandwidth: 2 Gb/s

  What is the minimum number of CNAs they would need to install an each server to meet the bandwidth required for the Tier 1 application while providing CAN redundancy and high availability?

  A. 1
  B. 2
  C. 3
  D. 4
  B. 2
