NCSE-Core Practice Test

Explanation:

A prospect is replacing a 3-tier virtualization infrastructure composed of several ESXi hosts and a SAN. They recently purchased a new 4-socket server to host their SQL server workload using the same SAN. Here is how Acropolis Block Services (ABS) allows them to continue using their new server without buying another SAN:

Requirement Analysis:The prospect needs to utilize their new server with the existing SAN without purchasing additional SAN hardware.

Feature Analysis:

Heterogeneous clusters: This feature allows mixing different types of nodes in a Nutanix cluster but does not specifically address the need to leverage an existing SAN.

Acropolis Block Services (ABS): ABS enables Nutanix clusters to provide block storage directly to external physical or virtual machines over iSCSI. This would allow the new 4-socket server to use the existing SAN storage as if it were local storage.

Virtual Fiber Channel Controller: This would require specific hardware support and might not align with the existing infrastructure.

Acropolis Container Services (ACS): ACS provides persistent storage for containerized applications and does not specifically address the need for utilizing an existing SAN with the new server.

Conclusion:ABS is the appropriate feature as it allows the new 4-socket server to access the existing SAN storage over iSCSI, integrating it seamlessly into the Nutanix environment without additional SAN purchases.

Explanation:

To size a new project that requires offsite backup using Veeam with an RPO of 24 hours and the ability to restore from the past 7 days of backups, while considering the data change rate of 1%, the SE should configure the Nutanix Sizer with the following parameters:

Backup Frequency: Since the required RPO is 24 hours, a daily backup schedule should be set. Retention Policy: The retention policy should be set to retain daily backups for 7 days. This means that each backup is kept for a week before it is overwritten.

Data Change Rate: The data change rate is 1%. This information is crucial for sizing the backup storage. A 1% daily change rate indicates that each daily backup will be approximately 1% of the total data size.

Backup Target: Veeam should be configured to send backups to an offsite location. This can be an external storage repository or a cloud target.

Storage Calculation: Calculate the total backup storage requirement. If the total data size is D, then the daily backup size will be 0.01D. Over 7 days, the storage requirement will be approximately 0.07D.

The SE should enter these details into the Nutanix Sizer to ensure the configuration aligns with the prospect's requirements.

Explanation:

Customer Requirement:

Data-at-Rest-Encryption for all data.

License Options:

Pro with the Encryption SKU: This option allows customers to add encryption capabilities to the Pro tier.

Ultimate: This tier includes built-in encryption features, providing comprehensive data security.

Explanation:

Pro with the Encryption SKU: Customers using the Pro tier can enhance their security by purchasing the additional Encryption SKU, which enables Data-at-Rest-Encryption.

Ultimate: This tier natively includes encryption, offering an all-in-one solution for customers requiring high levels of data security without additional SKUs.

Outcome:

Customers can choose either of these two licensing options to meet their Data-at-Rest-Encryption requirements, ensuring that all their data is securely encrypted.

Explanation:

For network switch discovery in Prism, the following settings are required:

Switch Management IP Address: This is necessary to access and manage the network switch. AHV Host IP address: This helps in identifying the hosts connected to the network.

SNMP Community Name: This is used for SNMP protocol to monitor and manage the network devices.

Explanation:

When discussing Nutanix differentiators with a prospect considering vSAN for their HCI initiative, especially for read-intensive workloads with over 1PB of archival data, the following features should be highlighted:

Compression on Hybrid Nodes:

Nutanix provides efficient data compression on hybrid nodes, significantly reducing the storage footprint and saving costs. This is particularly beneficial for archival data, which can be highly compressible, thus maximizing storage efficiency and reducing the total cost of ownership. Data Locality:

Nutanix's data locality feature ensures that data is kept local to the node where the VM is running. This reduces latency and enhances performance, particularly for read-intensive workloads, by minimizing the need for data to travel across the network.
