   A network team needs to monitor traffic from multiple switches in different buildings on a campus network. The monitoring tool is centralized in the data center. The campus network uses a routed core. The team wants to minimize the configuration overhead on the access switches and avoid extending Layer 2 domains. Which solution is the most appropriate?

   • AConfigure local SPAN on each access switch and connect the destination ports to the core network.
   • BConfigure RSPAN on each access switch and extend the RSPAN VLAN across the routed core.
   • CConfigure ERSPAN on each access switch with the centralized analyzer's IP address as the destination.
   • DUse a network TAP on the uplink of each access switch and send the traffic to the analyzer.

   A network team is designing a monitoring solution. The traffic to be monitored is on a switch in a remote data center. The monitoring tool is in the main data center. The two data centers are connected via a routed WAN. The team wants to minimize the amount of configuration on the remote switch and avoid sending any traffic other than the mirrored traffic over the WAN. Which method is the most appropriate?

   • AConfigure ERSPAN on the remote switch with the monitoring tool's IP address as the destination.
   • BConfigure local SPAN on the remote switch and connect a laptop to the destination port.
   • CConfigure RSPAN on the remote switch and extend the RSPAN VLAN over the WAN.
   • DUse a network TAP on the remote switch and send the traffic to the monitoring tool.

   A network engineer must choose a monitoring method for a distributed environment. The traffic to be monitored is on a VLAN that spans several access switches in the same data center. The analysis tool is connected to a dedicated management switch in the same data center. The engineer wants to minimize overhead on the access switches and avoid sending mirrored traffic over the core network. Which method is the most appropriate?

   • AConfigure RSPAN with a dedicated VLAN on the access switches and a destination session on the management switch.
   • BConfigure ERSPAN on each access switch with the management switch's IP address as the destination.
   • CConfigure local SPAN on each access switch and connect the destination ports to the management switch.
   • DUse a network TAP on the uplink of each access switch.
