At ValidExamDumps, we consistently monitor updates to the Nutanix NCS-Core exam questions by Nutanix. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Nutanix Certified Services Core Infrastructure Professional v6.8 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Nutanix in their Nutanix NCS-Core exam. These outdated questions lead to customers failing their Nutanix Certified Services Core Infrastructure Professional v6.8 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Nutanix NCS-Core exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
What is the default password shipped on new NX hardware from the factory for the ADMIN user on IPMI?
Nutanix Security: As part of security improvements (complying with California statute SB-327), Nutanix changed the default IPMI password policy.
Node-Specific Password: Each Nutanix NX hardware node now ships with a unique default IPMI password for the ADMIN user.expand_more This password is the node's serial number (using capital letters).expand_more
Finding the Serial Number: You can locate the node's serial number either on a physical sticker or by running the ipmitool fru print command on the node.

A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source.
What should an administrator do to resolve this issue?

An administrator needs to install prism central for their 2550 multi-cluster environment.
How should they deploy the application?
For managing a multi-cluster environment with a total of 2550 VMs, deploying a large 3-VM Prism Central instance is advisable. This setup provides the necessary scalability, redundancy, and performance to efficiently manage such a large number of VMs across multiple clusters. A 3-VM configuration ensures high availability and fault tolerance, crucial for maintaining consistent operations and management across the clusters.
A consultant is viewing an ESXi host via console without external network connectivity.
Which two IP addresses can be used to connect to the CVM (Choose two.)
In the scenario where a consultant is viewing an ESXi host via console without external network connectivity and needs to connect to the Controller Virtual Machine (CVM), the typical IP addresses used for such connections in a Nutanix environment are in the 192.168.5.x range. Specifically, the IP addresses for CVMs often set by default or during initial configuration, such as 192.168.5.253 and 192.168.5.254 (Options A and C), can be used. These addresses are generally reserved for internal CVM communications and can be accessed through the host's internal network configurations.

Over the period of 2 to 3 weeks, a cluster displays the following:
* Periods where Warning Alerts of memory usage over 75% are asserted
* Periods where Critical Warnings of memory usage over 90% are asserted
* Periods of slow of frozen VDI desktops have caused work stoppage or slowdown
* VDI clones have periodically not powered up when called, causing work stoppage
Which steps should be used to prioritize the administrator's troubleshooting efforts?
For the scenario with memory usage warnings and VDI performance issues, the best approach is to analyze and understand the memory usage patterns and demands on the system. Option D focuses on reviewing the Analysis page to monitor memory use trends and patterns, which is crucial for identifying peak usage times or processes consuming excessive memory. The mention of alerting with VDI workload demand implies the need to monitor and possibly adjust the VDI workload to better fit within available resources. Finally, analyzing current and future workload in the Capacity Runaway tab helps in understanding if the cluster resources are sufficient for the demand, which is critical in planning for capacity management and ensuring that such issues are mitigated moving forward.
