A consultant is not able to run the As-Built Tool for a technical reason. What action should the consultant take to gather information and provide customer documentation?


A. Manually create documentation using As-Built document template.


B. Use RVTools for vSphere and Hyper-V deployments.


C. Create a support case on behalf of a customer.


D. Access portal.nutanix.com, search Software Documentation.





A.
  Manually create documentation using As-Built document template.

Explanation: If the As-Built Tool cannot be run due to technical reasons, the next best action for the consultant is to manually create documentation using an As-Built document template. This approach ensures that documentation is still provided to the customer detailing the setup, configuration, and operational state of their environment, which is crucial for ongoing management and future audits. This method is proactive and ensures customer needs are met despite technical setbacks.

An administrator needs to forecast infrastructure requirements for a new program and its associated applications. Prior to the projected start of the new program, all existing applications will be decommissioned. How should the administrator perform this task?


A. Check the Disregard Existing Workloads radio button in the Runway scenario.


B. Check the Disregard Existing Nodes radio button in the Runway scenario.


C. Add up the recovered workloads and manually remove from the Runway configuration.


D. Power down the workloads during a maintenance window and run the Capacity Runway.





A.
  Check the Disregard Existing Workloads radio button in the Runway scenario.

During a technical call with a customer, it is identified that this installation will be software only on Dell servers. The out-of-band management interfaces will not be given IP addresses until the consultant is onsite. Which Foundation method should be used for this type of installation?


A. Bare metal using iDRAC MAC addresses.


B. Bare metal using LAN MAC addresses.


C. Bare metal using block serial numbers.


D. Bare metal using node serial numbers.





A.
  Bare metal using iDRAC MAC addresses.

Explanation: In scenarios where a software-only installation is planned on Dell servers without pre-configured IP addresses for out-of-band management interfaces, the iDRAC MAC addresses are crucial. Using iDRAC (Integrated Dell Remote Access Controller), a consultant can perform a bare metal installation remotely and manage the servers effectively. This method is preferable when IP addresses are not initially available, allowing the consultant to utilize the out-of-band management network for setup. References: Nutanix Installation and Configuration guides, especially those pertaining to Dell hardware, available through the Nutanix Bible and official Nutanix training materials.

A customer needs to meet the following requirements for their business critical application:
* SQL Servers must be on specific hosts to lower licensing costs.
* Oracle RAC servers must be on separate hosts for licensing reasons
Which policy or policies should be implemented to meet these requirements?


A. Configure VM-VM anti-affinity policy.


B. Configure VM-VM affinity policy.


C. Configure both VM-Host and VM-VM affinity policy.


D. Configure VM-Host affinity policy.





D.
  Configure VM-Host affinity policy.

Explanation: For licensing reasons and to ensure compliance with software license terms, particularly for databases like SQL and Oracle RAC, VM-Host affinity policies are used. These policies help in pinning VMs to specific hosts. In this scenario, SQL Servers must be confined to specific hosts to manage licensing costs effectively, and similarly, Oracle RAC servers must be on separate hosts. The VM-Host affinity policy allows for such configuration by defining rules that keep VMs on specific hosts or separate them as needed.

An administrator inherits a new Nutanix environment and logs in to a CVM to check the network configuration. The configuration is as follows:

Which action should the administrator take to improve network performance?


A. Configure VLAN tagging both on br0 and br1 and their physical interfaces.


B. Add eth0 and eth1 to the br0-up bond


C. Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows


D. Remove one 10 Gbs interface from br0-up to make sure all 10 Gbs can be used.





C.
  Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows

Explanation: Upon reviewing the network configuration in the provided image and considering the setup in a Nutanix environment, the best action to improve network performance is to adjust the bonding mode for the bridge that includes multiple highbandwidth interfaces.
Option C, "Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows," is the most effective choice. The bonding mode "balance-sib" (source IP-based load balancing) or "balance-tcp" (TCP/IP layer balancing) can optimize the distribution of network traffic across multiple interfaces, thereby enhancing throughput and redundancy.
This approach utilizes the capabilities of multiple network interfaces more efficiently, distributing the load to prevent any one interface from becoming a bottleneck while providing failover redundancy.
