 The checkpoint named “system-fm-vrrp” was created by an admin, as indicated by the description “Created by Feature Manager.” This suggests that it was a deliberate action rather than an automatic response to a service restart or crash. Checkpoints in Cisco systems can be manually created for various reasons, such as before making significant changes to the configuration, which allows for a rollback to a known good state if necessary.

References := For more information on the creation and management of checkpoints in Cisco systems, one should refer to the Cisco Data Center Core Technologies documentation and study materials, which provide detailed procedures and best practices.

 To block traffic between a subset of endpoints in an EPG based on specific VM attributes and the rest of the VMs in that EPG, the correct set of actions would involve setting “Allow Microsegmentation” under the EPG VMM Domain Association to “True” and setting “Intra-EPG Isolation” to “Enforced” for both the EPG and the uSeg EPG. This configuration ensures that microsegmentation is allowed and that intra-EPG isolation is enforced, effectively blocking the specified traffic.

 When storm control is applied to an interface with a zero percent value, it means that the switch will not tolerate any traffic that exceeds the bandwidth of the interfaces during a streaming window. The switch monitors the levels of incoming broadcast, multicast, and unicast traffic over a 1-second interval. When the configured threshold level is reached, further traffic in this category is dropped until the level falls below the threshold.

 This type of backup includes information about VLANs, VSANs, and other policies and is in XML format, which is human-readable. Although the question specifies the use of UDP, none of the options provided use UDP as they are all TCP-based protocols; however, TFTP is often confused with being UDP-based because it is a lightweight protoco

 A community cloud Infrastructure as a Service (IaaS) deployment model is suitable for several companies that need to operate the same application environment and integrate it with third-party protocols. It allows the development team to have control over the infrastructure, including the operating system, Python interpreter, and libraries

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

 Multipathing iSCSI traffic is a technique to provide redundancy and load balancing for iSCSI connections between a server and a storage device. Multipathing can be achieved by using multiple initiators, multiple targets, or both. However, some design choices are more optimal than others, depending on the network topology and the capabilities of the devices involved. Option C, “dual initiators to a single target with bonded interfaces,” is a recommended design choice because it provides the following benefits:

• It allows the server to use two separate network interface cards (NICs) to connect to the same iSCSI target, which increases the bandwidth and availability of the connection.
• It enables the use of link aggregation or bonding on the target side, which combines multiple physical interfaces into a logical interface that can handle more traffic and tolerate link failures.
• It simplifies the configuration and management of the iSCSI sessions, as there is only one target to deal with, and the multipathing software can handle the path selection and failover.

The system will automatically revert to the backup image version if the endpoint fails to boot from the new firmware image. This is a feature of the Fabric Interconnects that ensures high availability and reliability. The GOLD firmware image is used for diagnostics and troubleshooting, not for normal operation. The kickstart image is used for booting the Nexus switches, not the Fabric Interconnects. References:

 ARP suppression is a feature used in VXLAN/EVPN environments to optimize ARP responses and reduce unnecessary ARP broadcasts across the fabric. When ARP suppression is enabled, the local VTEP (VXLAN Tunnel Endpoint) can respond to ARP requests for known IP-to-MAC address bindings, which are learned via the BGP EVPN control plane. This prevents the need for ARP broadcasts to be sent across the entire VXLAN fabric, thus optimizing the ARP response mechanism and reducing broadcast traffic1.

 In a vPC (Virtual Port Channel) data center interconnect, both vPC peer devices must have the same system MAC address to ensure that remote switches perceive them as a single logical switch. Since the system MAC value on SW1 is 00:23:04:ee:be:20, the same value must be configured on SW3 to maintain consistency in the vPC domain and ensure seamless communication between the two data center fabrics connected through this vPC interconnect.

References: = The explanation can be inferred from Cisco’s official documentation and resources related to configuring and managing vPCs, ensuring that both peer devices in a vPC domain are configured with identical parameters, including the system MAC address.
