NCP-MCI-6.5 Exam Questions Tutorials

Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments1. Prism Central can be deployed in different configuration scenarios, depending on the network and security requirements of the environment. Some of the valid scenarios are:

• Environments use Network Address Translation (NAT): NAT is a method of mapping one IP address space to another by modifying network address information in IP datagram packet headers while they are in transit across a traffic routing device2. NAT can be used to enable communication between Prism Central and Prism Elements that are in different networks or subnets3. For example, Prism Central can be deployed in a public cloud and use NAT to access Prism Elements that are in a private data center3.
• Prism Elements and Prism Central are in different subnets: A subnet is a logical subdivision of an IP network that allows multiple networks to share a single physical network4. Prism Elements and Prism Central can be in different subnets as long as they can communicate with each other through routing or NAT3. For example, Prism Central can be deployed in a management subnet and access Prism Elements that are in different application subnets3.
• Environments do not have Internet access: Internet access is not required for the deployment of Prism Central, as long as the environment meets the prerequisites and considerations for installing or upgrading Prism Central. For example, Prism Central can be deployed in a dark site, which is an environment that does not have Internet access or has restricted Internet access. In this case, the administrator needs to manually enable microservices infrastructure and download the required software packages from another source.

According to the Nutanix Support & Insights web search result3, advertised capacity is an advanced container setting that allows the administrator to reserve an advertised storage space for a storage container. An advertised capacity setting gives the hypervisor a maximum storage size that the storage container can use. This setting can be any arbitrary value greater than or equal to the resiliency required. The hypervisor ensures that the storage container storage doesn’t go beyond the advertised capacity. If the administrator wants a container to be displayed and limited to 1TB in the hypervisor, they should set the advertised capacity to 1TB.

The best way for the administrator to configure Prism to send encrypted messages to a set of recipients is to set the SMTP Security Mode to STARTTLS. This will ensure that all messages sent over SMTP are encrypted and secure. Additionally, the administrator should consider installing SSL certificates on Prism Central to ensure that the messages are being sent securely. Finally, the administrator should consider configuring Prism Central to use Cluster Lockdown, which will help ensure that the messages are only sent to the intended recipients.

According to the Nutanix AHV Networking Guide, active-active bond mode provides load balancing and fault tolerance for network traffic by distributing packets across multiple interfaces using a hashing algorithm based on source and destination MAC addresses, IP addresses, and TCP/UDP ports. This mode does not require any special configuration on the network switch and can improve throughput for hosts with many small VMs.
