 IP ARP suppression (D) is used in VXLAN EVPN environments to minimize flooding. When enabled, it allows the local switch to respond to ARP requests for known hosts, thus preventing the need to flood these requests across the entire network segment1. This feature is particularly useful in scenarios where there is a large amount of ARP traffic that could potentially lead to flooding, as it reduces unnecessary broadcast traffic by handling ARP resolution within the control plane2.

References: The role and configuration of IP ARP suppression in VXLAN EVPN environments are detailed in Cisco’s documentation and best practice guides for VXLAN BGP EVPN

Cisco Data Center Network Manager (DCNM) is the monitoring solution that can fulfill the requirements of visualizing the SAN, supporting VXLAN overlays, and identifying storage slow drain issues for a Fibre Channel storage environment consisting of Cisco Nexus 9000 and MDS 9000 Series Switches3.

A logical configuration backup of a Cisco UCS Manager database is a file that contains all of the configurations that are stored in the Cisco UCS Manager database, such as policies, pools, service profiles, templates, and firmware versions. The file has an extension .tgz and can be created and restored using the Cisco UCS Manager GUI or CLI. A logical configuration backup also contains the configuration organizations and locales, which are logical entities that group and isolate resources within a Cisco UCS domain. Organizations and locales can be used to delegate administrative tasks and privileges to different users or groups. The other options (AAA and RBAC configurations, VLAN and VSAN configurations) are not part of a logical configuration backup, but rather a full state backup, which is a different type of backup that includes the operational state and statistics of the Cisco UCS domain. References: For more information on how to create and restore a logical configuration backup of a Cisco UCS Manager database, please refer to the following resources:

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives. References :=
