Nutanix NCSE-Core Exam With Confidence Using Practice Dumps

Understanding the Requirements:

Replicating data offsite involves several key considerations to ensure data integrity, availability, and compliance with business needs.

Key Questions:

Retention Requirements: Determines how long the replicated data needs to be kept, which impacts storage needs and costs. This helps in defining the replication and retention policies (Nutanix Bible, Data Protection section)​​.

Data Volume: Knowing the amount of data to be replicated ensures proper sizing of network and storage resources. It also helps in understanding the replication bandwidth and storage capacity required (Nutanix-NDB-User-Guide)​​.

WAN Speed and Latency: The speed and latency of the WAN link between source and target sites affect replication performance and the ability to meet RPO (Recovery PointObjective) and RTO (Recovery Time Objective). High latency can impact data transfer rates and consistency (Nutanix-NDB-User-Guide, Network Requirements section)​​.

Conclusion:

Asking these questions ensures the SE can design a replication solution that meets the prospect's business continuity and disaster recovery needs effectively.

Three valid configuration scenarios for deploying Prism Central include:

Environments use Network Address Translation (NAT): Prism Central can be deployed in environments where NAT is used to manage network addresses.

Prism Elements and Prism Central are in different subnets: It is possible to configure Prism Central and Prism Elements in different subnets as long as network connectivity is maintained.

Environments do not have Internet access: Prism Central can be deployed and operated in environments that do not have direct Internet access, relying instead on internal network configurations and management​​.

In the Nutanix Distributed Storage Fabric, write I/O that is deemed sequential first enters the Oplog. The Oplog is designed to handle high-throughput write operations efficiently by temporarily storing the incoming writes before they are later consolidated and written to the extent store.
