DTLS (Datagram Transport Layer Security) is designed to provide security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. It is suitable for securing JSON encoded telemetry data sent to an external collector1.

 Including EPG-2, EPG-3, and EPG-4 in the preferred group allows these EPGs to communicate with each other without requiring any contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate by default. However, since the secure server in EPG-1 must provide services to EPG-2, a contract is required between EPG-1 and EPG-2 to facilitate this communication while maintaining the security and policies necessary for the server.

References := For more detailed information on configuring EPGs and contracts in Cisco ACI, you can refer to the Cisco Data Center Core Technologies (DCCOR) study materials and official Cisco documentation. These resources provide comprehensive guidance on the implementation and management of EPGs, contracts, and preferred groups within a Cisco ACI environment.

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

 The auditor requires read-only access to perform the configuration review. The permit command show * grants the auditor access to all show commands, which are typically used to view configurations and statuses without making changes, thus maintaining the read-only requirement. References: This is aligned with the best practices for role-based access control (RBAC) in Cisco Nexus switches, as detailed in the DCCOR course materials.

 SSH (Secure Shell) is the protocol that allows secure remote login from one computer to another. It provides strong authentication and secure communications over unsecured channels. This protocol is preferred for automated onboarding of devices like Cisco Nexus 9000 Series Switches because it supports strong encryption and credential-based authentication, which aligns with the requirement for minimal connection methods and security. SSH is commonly used in network automation for secure command execution and file transfers1.

References := For more information on configuring Cisco Nexus 9000 Series Switches for automation and integration with systems like Cisco UCS Director, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the supported manageability features and advanced automation capabilities, including Power On Auto Provisioning (POAP) and integration with automation frameworks

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:
