1. What is zoning? Discuss a scenario:

a. Where WWN zoning is preferred over port zoning.

b. Where port zoning is preferred over WWN zoning.

2. Seventeen switches, with 16 ports each, are connected in a mesh topology. How many ports are available for host and storage connectivity if you create a high-availability solution?

3. Explain storage migration using block-level storage virtualization.

4. How does iSCSI handle the process of authentication?

5. Why should an MTU value of at least 2,500 bytes be configured in a bridged iSCSI environment?  

6. Consider the following Scenario: 

Scenario: 

•The financial activity of all regional offices of an organization is carried out through an accounting application: –The application generates 15% random writes and 85% random reads –The storage currently has a 5-disk RAID 0 configuration –Each disk has an advertised formatted capacity of 250 GB –The total size of the application’s data is 900 GB, which is unlikely to change over the next six months 

Requirements and challenges: 

•The organization plans to reconfigure storage with fault tolerance 

•The organization cannot afford new disk purchases Deliverables: •Recommend a RAID level for reconfiguring the storage to fulfill the organization’s requirements 

•Justify the choice of RAID level based on cost, performance, and availability

7. Describe switched fabric N-ports, E-ports, F-ports and G-ports.

8. When is unified storage a suitable option for a data center?
