Question 4.
You have a single fabric with four servers connecting to an edge switch in a core edge configuration with single 2Gb/s ISLs to the core. Each server has an average throughput requirement of 40MB/s. 

Under which circumstance would you need to add a second ISL?

A. to provide a redundant path
B. to avoid congestion on the ISL
C. to separate out FSPF updates
D. to provide a management path

Answer: A

Explanation:

Question 5.
Two servers have been connected to a SAN with redundant fabrics and the zone configuration needs to be changed. 

How can you safely change the zone configuration?

A. Save the current zone configuration to disk, modify it and apply it to both fabrics 
    simultaneously to avoid segmentation.
B. Modify the zone configuration on one fabric, test it, and then modify the zone configuration on the second fabric.
C. Modify the zone configuration on one fabric, test it, and then copy the zone configuration to the second fabric.
D. Modify the zone configuration on both fabrics at the same time, enable them simultaneously to avoid segmentation.

Answer: B

Explanation:
