You must ensure that both chassis are assembled for highest availability. You have a total of four SFMs to deploy in the two chassis. Which slot combinations provide the expected results? To form a Brocade VCS Fabric between a Brocade VDX 6730 and a VDX 6740T, what is required? In which two port types would QoS flow control be enabled? (Choose two.) You want to design a Brocade VCS Fabric that can automatically classify and prioritize traffic for NAS storage. Which two platforms would be used? (Choose two.) You have implemented flow-based sFlow in your Brocade VCS Fabric by enabling sFlow globally on each Brocade VDX. You are not receiving any statistics in your sFlow collector from these devices. What must happen to start collecting data? Which M-Series switch is supported in a Brocade VCS Fabric? Which three steps are required for a firmware upgrade from a USB flash drive? (Choose three.) You want to create an aggregated link to a hypervisor that does not support LACP. What is the mode that needs to be configured on the channel group? You are using PBR in your Brocade VCS Fabric and you would like to selectively modify and route the IP packets in the hardware. Which two would you configure? (Choose two.) You have a Brocade VDX switch in production and you must save a backup copy of the running configuration to a remote location. What are two ways to accomplish this task? (Choose two.) You want to implement VRRP-E between a Brocade VDX 6740, and a Brocade VDX 6730 with the protocol vrrp command. Which two statements are true? (Choose two.) A customer has a four-port vLAG between two VDX switches and a server. Two of the four links are up but the vLAG will not come up.
