NCSE-Core Exam Dumps - Nutanix Certified Systems Engineer-Core (NCSE-Core 6.8)

When providing a quote for a hybrid cluster to a customer with an existing vSAN ReadyNode quote, it is essential to avoid sizing solely based on the competitor's bill of materials for the following reasons:

Customer Requirements:

No Visibility to Actual Requirements: Sizing based on competitor's specifications without understanding the customer's specific requirements can lead to suboptimal solutions. The customer’s workload characteristics, performance expectations, and future growth plans must be considered.

Competitor Assumptions:

Unknown Assumptions: The assumptions made in the competitor's sizing, such as expected workload intensity, redundancy needs, and performance criteria, are not clear. These assumptions can vary significantly and may not align with the actual needs of the customer.

Customized Solution:

A tailored solution based on a thorough assessment using tools like Nutanix Sizer and Nutanix Collector ensures the configuration meets the specific performance, capacity, and resilience requirements of the customer.

D. Automatic Workload Repository Report:

The Automatic Workload Repository (AWR) report provides comprehensive details about Oracle database performance, workload characteristics, and resource utilization. This report is crucial for accurately sizing an environment that includes production Oracle databases.

AWR reports contain historical data on system performance and are used to identify trends, workload patterns, and potential bottlenecks. This information is essential for determining the appropriate resources needed to support the Oracle databases in the Nutanix environment.

References:

Nutanix documentation and Oracle best practices for database sizing recommend using AWR reports for accurate performance and capacity planning.

When selecting a remote site to Prism, the valid targets include:

XI Cloud Services: This allows integration with Nutanix's cloud services for remote management and disaster recovery.

Physical Cluster: This option enables management and failover to another physical Nutanix cluster, ensuring high availability and business continuity​​.

The status shown in the exhibit within the Hardware Diagram section indicates a critical hardware issue that needs immediate attention.

Reseat Disks/Nodes: While reseating might help with connectivity issues, it should be performed with caution and typically after consulting support to avoid data loss or further complications.

Resolve Alerts and Re-import Disks: This step is useful but secondary to ensuring that applications are not negatively impacted. Immediate action should focus on stability and minimizing downtime.

Restart CVMs: Restarting CVMs might help but could also disrupt services and should be a last resort after consulting with support.

Application Status and Support: Checking the status of applications ensures that any critical services are not interrupted, and calling support provides access to Nutanix's expertise to address the hardware issue effectively.

Given the critical nature of hardware issues and the potential impact on the cluster, contacting support while checking the application status is the best course of action to ensure a safe and effective resolution.

1 x 480GB SSD:

For a hybrid cluster running both general-purpose VMs and an ERP application with a 500GB database, having a single 480GB SSD may lead to performance bottlenecks.

Nutanix best practices recommend using multiple SSDs for better I/O performance and redundancy​​​​.

2 x 1GB NIC:

The network interface cards (NICs) with only 1GB capacity each are insufficient for a production environment expected to handle significant data and application traffic.

Nutanix typically recommends 10GB NICs for adequate bandwidth and performance in such scenarios​​.

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​​​​.

A. Option A:

To configure Sizer for a scenario that requires offsite backup but not remote disaster recovery, with an RTO of 48 hours, RPO of 4 hours, and the ability to restore from the past 5 days of backups, the SE needs to ensure that the Sizer settings reflect these requirements.

Given the prospect's data change rate of 1%, the SE should configure Sizer to handle the daily backup data and the total data retention period. Option A likely represents the configuration that meets these parameters.

References:

Nutanix Sizer tool guidelines and documentation on configuring backup and data retention settings provide the necessary steps to ensure the configuration meets the specified RTO and RPO requirements.
