NCSE-Core Practice Test

Explanation:

To get timely notifications of significant product issues, customers should register for Field Advisories email notifications. This ensures that they receive updates directly and promptly, keeping them informed about any critical issues or advisories related to Nutanix products.

References:

Nutanix support resources and customer documentation provide guidance on how to register for email notifications for Field Advisories, ensuring customers are kept up to date with important product information.

Explanation:

Problem Analysis:

The customer needs to replace an existing 200TB filer with a Nutanix solution.

The filer is used for storing archived images, requiring maximum storage density.

The proposal includes using RF2 and Erasure Coding with a stripe size of 4/1 (data/parity).

Erasure Coding Requirements:

Erasure Coding (EC-X) in Nutanix improves storage efficiency by distributing data and parity across multiple nodes.

A 4/1 stripe size means 4 data blocks and 1 parity block.

To implement a 4/1 Erasure Coding stripe, a minimum of 5 nodes is required to ensure the distribution of data and parity blocks.

Explanation:

RF2 (Replication Factor 2): Requires at least two copies of the data to be stored on different nodes.

Erasure Coding with a 4/1 Stripe: Requires 5 nodes to ensure there are enough blocks to store the 4 data and 1 parity blocks.

Outcome:

The minimum number of nodes required to support the maximum Erasure Coding stripe size of 4/1 is 5 nodes.

Explanation:

Federal Government Encryption Requirements:

Compliance with strict encryption standards such as FIPS 140-2 is mandatory.

Required Items:

Self-Encrypting Drives (SEDs): Provide hardware-level encryption ensuring data at rest is encrypted.

Supported Key Management Server (KMS): Manages encryption keys in a secure and compliant manner.

Licensing and Software:

Nutanix Acropolis Pro Licensing: Necessary for certain advanced features but not directly related to meeting encryption standards.

Nutanix Software Encryption: Useful but hardware encryption (SEDs) and a supported KMS are essential for compliance.
