• Question 151:

  A SAN administrator has a dual fabric (Fabric-A and Fabric-B) NSPOF SAN with Windows hosts that are connected to an EVA storage subsystem. Each host has two HBAs and Secure Path. The administrator needs to move all the data traffic to Fabric-B. What are two recommended ways to accomplish this? (Choose two.)

  A. use Secure Path to move the LUN access to the required HBA
  B. disable all the switches in Fabric-A
  C. disable all the switch ports in Fabric-A attached the HBAs in the hosts
  D. power off all the switches in Fabric-A
  E. disconnect the cables from the HBAs attached to Fabric-A
  A. use Secure Path to move the LUN access to the required HBA
  C. disable all the switch ports in Fabric-A attached the HBAs in the hosts

• Question 152:

  What does a SAN high availability configuration provide?

  A. a non-disruptive merging of multiple SANs
  B. the capability to test new switch firmware in a production environment
  C. a non-disruptive upgrade process of theiSCSI protocol definitions
  D. non-disruptive SNMP messages to the system management framework
  A. a non-disruptive merging of multiple SANs

• Question 153:

  What virtualization model is used in the Continuous Access Storage Appliance (CASA)?

• Question 154:

  What problem can arise when scaling or merging SAN fabrics?

  A. If the discovery process determines specific cabling changes are required, then the merge will fail over.
  B. If the discovery process determines that the fabrics are not compatible, then the fabric will segment.
  C. If the discovery process determines changes in business requirements, then the SAN merge will fail.
  D. If the discovery process determines that the fabrics have different security levels, than the most secure level will be adopted.
  B. If the discovery process determines that the fabrics are not compatible, then the fabric will segment.
