Question No. 1

During the Foundation imaging process, nodes are successfully imaged, but the cluster creation fails.

Which log should the consultant review to determine the cause?

Show Answer Hide Answer
Correct Answer: B

During the Nutanix Foundation process, if imaging succeeds but cluster creation fails, the foundation.out log is the primary resource for investigating issues related to cluster creation. This log file contains detailed information about the steps undertaken by the Foundation process, including any errors or issues encountered during the cluster creation phase, making it invaluable for diagnosing problems that prevent successful cluster configuration.

Question No. 3

An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:

* 30 nodes: distributed 10 nodes per rack across three 42U rack

* Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)

* Current cluster utilization is 900TB storage

Which configuration changes should be made to make sure that the cluster meets the requirements?

Show Answer Hide Answer
Correct Answer: A

In Nutanix, a cluster with RF2 (Redundancy Factor 2) can tolerate the failure of a single node or drive1. However, to ensure that the cluster can survive a complete rack failure without negatively affecting workload performance, we need to consider rack awareness. When rack fault tolerance is enabled, the cluster has rack awareness and the guest VMs can continue to run with failure of one rack (RF2) or two racks (RF3).The redundant copies of guest VM data and metadata exist on other racks when one rack fails2.

Given the current cluster configuration (30 nodes distributed 10 nodes per rack across three 42U racks), adding 3 additional nodes per rack (9 nodes total) would increase the redundancy of the cluster and improve its ability to withstand a complete rack failure. This is because the additional nodes would provide more storage capacity and compute resources, allowing the cluster to continue running workloads even if one rack fails.

Question No. 4

An administrator is responsible for the following Nutanix Enterprise Cloud environment:

* A central datacenter with a 20-node cluster with 1.5PB of storage

* Five remote sites each with a 4-node cluster with 200TB storage

The remote sites are connected to the datacenter via 1GB links with an average latency of 6 ms RTT. What is the minimum RPO the administrator can achieve for this environment?

Question No. 5

When utilizing the Nutanix cluster As Built Document generator, which two configuration elements should a consultant provide when running the run_as_built.exe command? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, D

When using the Nutanix cluster As Built Document generator, the necessary configuration elements to provide when running the run_as_built.exe command include the Cluster IP (B) and the Customer Name (D). The Cluster IP is required to properly identify and communicate with the cluster to gather configuration and operational dat

a. The Customer Name is typically used to personalize the documentation, making it specific to the client's deployment, which is useful for record-keeping and future reference purposes. Reference: Nutanix As Built Documentation generator usage guidelines, Nutanix Best Practices for Documentation.
