   A data center engineer is planning to use SPAN to monitor a high-throughput storage network link that carries iSCSI traffic. The engineer is concerned about packet loss during peak hours. Which action should the engineer take to mitigate the risk of dropped packets?

   • AConfigure the SPAN destination port with a higher speed than the source port.
   • BUse a SPAN destination port that is on the same line card as the source port.
   • CUse a VLAN SPAN session instead of an interface SPAN session.
   • DEnable SPAN on the supervisor module to offload processing.

   A data center engineer is using SPAN to monitor a 40GbE link that carries storage replication traffic. The SPAN destination is a 10GbE port connected to a monitoring appliance. During peak hours, the engineer notices that the monitoring appliance is missing packets. What is the most likely cause and the best solution?

   • ASPAN is dropping packets because of a software bug; upgrade the switch software.
   • BThe SPAN destination port is oversubscribed; use a 40GbE destination port or filter the SPAN source.
   • CThe SPAN session is not configured with the 'both' direction; change it to 'both'.
   • DThe monitoring appliance is not powerful enough; upgrade the appliance CPU.

   A network engineer is setting up monitoring for a storage network that uses Fibre Channel over Ethernet (FCoE). They want to use SPAN to capture FCoE traffic for troubleshooting. What should the engineer consider?

   • ASPAN only captures IP traffic, so FCoE is not visible.
   • BSPAN can capture FCoE traffic if the source is a physical interface or VLAN that carries FCoE.
   • CSPAN cannot capture FCoE traffic because it is a storage protocol.
   • DSPAN requires a special license to capture FCoE traffic.
