Q7. - (Topic 1) 

Your network and storage teams have decided to disable flow control on all host, switch, and NetApp interfaces, both 1 Gb and 10 Gb, to increase performance. 

Why does this action increase performance? 

A. It lets the NetApp MTU handle congestion control as needed. 

B. It lets the host-side MTU handle congestion control as needed. 

C. It lets the upper layer protocols handle congestion control as needed. 

D. It lets the lower layer protocols handle congestion control as needed. 

Answer:

Explanation: Ports with standard MTU size and jumbo MTU size should never be mixed on the same VLAN. Consider a host and a NetApp F AS device configured on the same VLAN, where the FAS controller is configured for jumbo frames and the host is not. The host will be able to communicate to the FAS device using its standard 1500 byte frames. However, the reply back from the FAS device wi ll be a 9000 byte frame and because the two machines are located on the same VLAN, there is no device fragmenting this frame into the standard 1500 byte size for consumption by the host.
