Nutanix Certified Associate Practice Exam

What is the likely cause of not displaying network switch information in a Nutanix cluster when LLDP is enabled?

1. The cluster is using RDMA-enabled NICs

2. SNMP is not configured properly

3. br0 and br1 are not defined

4. The ISL between switches is not configured

The correct answer is: SNMP is not configured properly

The situation where network switch information is not displayed in a Nutanix cluster with LLDP (Link Layer Discovery Protocol) enabled is likely linked to improper configuration of SNMP (Simple Network Management Protocol). SNMP plays a crucial role in monitoring and managing network conditions, including the gathering of information from network devices like switches. When SNMP is not configured correctly, data retrieval from the network devices will fail, resulting in the absence of switch information within the Nutanix cluster's management interface, even though LLDP is functioning as intended. The LLDP protocol is designed to allow devices on the same local area network (LAN) to advertise their identity and capabilities to each other; however, without the correct SNMP setup, the Nutanix system would not be able to capture or interpret this information to present it. The other options, while they may present valid issues in specific contexts, do not directly address the display of switch information in relation to LLDP operations. For instance, using RDMA-enabled NICs could influence performance or connectivity but doesn't inherently prevent switch information from being visible via LLDP. Similarly, not defining the appropriate bridge interfaces or configuring inter-switch links might create broader network issues; however, these are not necessarily related to why switch information
