4. A financial institution has connected their FC SAN in their main data center to a FC SAN in a branch office using 10km of 62.5 micron dark fiber. The new switches in the main data center are 2Gb/s capable but the older switches in the branch office only support 1Gb/s. They cannot get the link to initialize. What is the most likely cause of the problem? a. They have insufficient buffer credits on the switches b. They should have installed single mode fiber c. Both switches must support 2Gb/s before the link will initialize d. They must enable both Class 2 and class 3 support
5. A university campus has connected two departments together, each containing a 1Gb/s FC fabric, over 5km of dark fiber. The ISL is up and running and the two fabrics have merged successfully, however they cannot achieve more than 100MB/s throughput. What is the most likely cause or resolution of the problem? a. The link distance is too long for 1Gb/s Fibre Channel ports b. They have insufficient buffer credits configured on each switch c. They must replace the switches with 2Gb/s switches d. The encapsulation overhead is too great
