Nutanix Objects, part of Nutanix Unified Storage (NUS), is an S3-compatible object storage solution that can be deployed on AHV or ESXi hypervisors. Deploying Objects has specific prerequisites to ensure successful installation and operation.
Analysis of Options:
Option A (Prism Central version is 5.17.1 or later): Incorrect. While Nutanix Objects requires Prism Central for deployment and management, the minimum version for Objects deployment is typically lower (e.g., Prism Central 5.15 or later, depending on the Objects version). Version 5.17.1 is not a specific requirement for Objects deployment on AHV or ESXi.
Option B (Port 9440 is accessible on both PE and PC): Correct. Port 9440 is used for communication between Prism Element (PE) and Prism Central (PC), as well as for internal Nutanix services. When deploying Objects, Prism Central communicates with the cluster (via Prism Element) to deploy Object Store Service VMs. This communication requires port 9440 to be open between PE and PC, making it a key prerequisite.
Option C (Valid SSL Certificate): Incorrect. While a valid SSL certificate is recommended for secure communication (e.g., for S3 API access), it is not a strict prerequisite for deploying Objects. Objects can be deployed with self-signed certificates, though Nutanix recommends replacing them with valid certificates for production use.
Option D (Nutanix STARTER License): Incorrect. The Nutanix STARTER license is an entry-level license for basic cluster functionality (e.g., VMs, storage). However, Nutanix Objects requires a separate license (e.g., Objects license or a higher-tier AOS license like Pro or Ultimate). The STARTER license alone does not support Objects deployment.
Why Option B?
Port 9440 is critical for communication between Prism Element and Prism Central during the deployment of Objects. If this port is blocked, the deployment will fail, as Prism Central cannot communicate with the cluster to deploy the Object Store Service VMs.
Exact Extract from Nutanix Documentation:
From the Nutanix Objects Deployment Guide (available on the Nutanix Portal):
“Before deploying Nutanix Objects on AHV or ESXi, ensure that port 9440 is accessible between Prism Element (PE) and Prism Central (PC). This port is required for communication during the deployment process, as Prism Central manages the deployment of Object Store Service VMs on the cluster.”
