Nutanix NCSE-Core Exam With Confidence Using Practice Dumps

Shadow Clones:

Shadow Clones are a Nutanix feature designed to enhance performance for read-heavy workloads like VDI during peak operations such as boot storms.

This feature ensures that frequently accessed data is available locally on all nodes, significantly reducing latency and improving read performance during boot operations​​​​.

Implementation Benefits:

Minimizes the boot time for linked clone desktops during shift changes.

Enhances overall user experience by reducing the I/O bottleneck during mass reboots

The Automatic sizing option in Nutanix Sizer provides a solution that meets the provided requirements and includes a default 25% growth capacity. This ensures that the initial configuration can handle current workloads and accommodate future growth without immediate additional investments​​.

To address the performance concerns of a prospective customer evaluating a hybrid configuration versus an all-flash array, the following Nutanix features should be discussed:

Data Locality:

Nutanix ensures that data is kept local to the node where the VM is running. This reduces latency and increases performance by minimizing the distance data must travel over the network.

Automatic Data Tiering:

Nutanix can automatically move frequently accessed data to faster storage tiers (e.g., SSDs) and less frequently accessed data to slower storage tiers (e.g., HDDs). This ensures that critical data gets the performance benefits of faster storage without the need for an entirely all-flash array.
