Cisco Updated 350-601 Exam Questions and Answers by diego

To monitor and export traffic to a Network Analyzer, particularly ingress traffic from Host-A and all traffic for VLAN 20 from Host-B, the engineer must implement a configuration that captures the specified traffic and directs it to the Network Analyzer tool. The correct configuration will depend on the capabilities of the network devices in use and the specifics of the Network Analyzer’s requirements.

 The configuration must include setting up a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session that mirrors the desired traffic to a port connected to the Network Analyzer. This would involve specifying the source interfaces or VLANs and the destination port for the mirrored traffic. Additionally, the configuration should ensure that the Network Analyzer is capable of receiving and processing the mirrored traffic, which may require additional settings on the Network Analyzer itself.

 Configuring Link Group Preference to Port Channel © allows the use of all four interfaces and provides link failure tolerance. This is because port channels can combine multiple physical links into a single logical link that provides high availability through redundancy. If one link in the port channel fails, traffic is automatically redistributed to the remaining links without any disruption to the network12.

References: The configuration of port channels and link group preferences in a Cisco UCS environment is detailed in Cisco’s official documentation and community discussions related to fabric failover and high availability

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

These resources provide comprehensive guidance on configuring and managing Cisco Nexus and MDS switches in a data center environment.

 To reduce disruptions during a major software upgrade on a Cisco Nexus Series switch, technologies like VDC (Virtual Device Contexts) and vPC (Virtual Port Channels) can be implemented. VDC allows for the partitioning of a single physical device into multiple logical devices, which can be managed and operated independently. This means that one VDC can be upgraded while others remain operational, minimizing downtime. vPC enables the linking of two switches to create a single logical switch, providing redundancy and allowing for one switch to be upgraded while the other maintains the network operations1.
