  Correct Answer: C

• Question 113:

  Which node type does not deploy a Nutanix Controller VM?

  A. Storage Only

  B. Hyper Converged

  C. Compute Only

  D. All Flash

  Correct Answer: C

• Question 114:

  Which Nutanix service control ncli, the HTML5 UI, and Rest API?

  A. Prism

  B. Cassandra

  C. Zookeeper

  D. Chronos

  Correct Answer: A

  Explanation: Prism is the central service control used by Nutanix to manage the clusters. It provides a unified view of the entire system, and it is used to control the HTML5 UI, the nCLI, and the REST API. Prism is used to manage the

  resources of the system, such as the nodes, storage, and networks, as well as to monitor the performance of the system and the applications running on it.

  Prism is the management gateway for components and administrators to configure and monitor the Nutanix cluster. This includes Ncli, the HTML5 UI, and REST API.

  Prism runs on every node in the cluster and uses an elected leader like all components in the cluster. All requests are forwarded to the leader using Linux Iptables. This allows access to PRISM using any CVM Ip address.

  Prism communicates with Zeus for cluster configuration data and Cassandra for statistics to present to the user. It also communicates with the ESXi hosts for VM status and related information

  These are only some of the essential services that make up the CVM functionality. For more information on all the services and various Nutanix Cluster components, refer to the portal documentation.

• Question 115:

  An administrator is troubleshooting vDisk performance issues in a Nutanix cluster with hybrid disks. The VMs all have Flash Mode enabled.

  But users are reporting disk latency.

  What could cause the performance issues?

  A. Flash mode is disabled when a node fails.

  B. Compression is disabled on the vDisk storage container.

  C. The VMs vDisks are in multiple containers.

  D. Data size for flash mode exceeds 25% of the SSD capacity.

  Correct Answer: D

  Explanation: data size for flash mode exceeds 25% of the SSD capacity could cause the performance issues. Flash mode is a feature that allows vDisks to be pinned to SSDs for faster access, but it has a limit of 25% of the SSD capacity per node. If this limit is exceeded, some vDisks may be evicted from flash mode and cause disk latency2.

• Question 116:

  Refer to Exhibit:

  

  An administrator needs to enable inline deduplication for a pre-existing storage container. When trying to enable deduplication on the storage container. this feature is grayed-out.

  What is the reason for this behavior?

  A. Replication Factor 1 is configured on the storage container.

  B. The cluster has less than 5 nodes which is the minimum node-count to enable deduplication.

  C. Capacity reservation is not enabled on the storage container.

  D. The cluster has hybrid storage and deduplication is supported only on all-flash clusters.

  Correct Answer: D

  Explanation: Nutanix supports two types of deduplication: post-process and inline. Post- process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to

  disk and can be enabled only on all-flash clusters.

  Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not. Nutanix inline deduplication is a feature that reduces the stored size and avoids

  duplicate data on a storage container1. It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads12.

• Question 117:

  An administrator needs to run a mixed Exchange and SQL workload with a guaranteed amount of container space for each application.

  How should the administrator meet this requirement?

  A. Create one container and set capacity reservation

  B. Create two containers and reserve space for containers

  C. Create one container and enable compression

  D. Create two containers and reserve space for vDisks

  Correct Answer: D

• Question 118:

  Prism Central will be installed manually on an AHV cluster.

  Which three disk images must be downloaded from the portal for the Prism Central VM? (Choose three.)

  A. var

  B. tmp

  C. boot

  D. home

  E. data

  Correct Answer: CDE

• Question 119:

  An administrator has been tasked with increasing security on Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH,

  What is the easiest way for the administrator to meet these needs?

  A. Configure LDAP authentication through a secure server,

  B. Enable STIES vie commend line on SSH to CVM.

  C. Enable Cluster Lockdown and provide an RSA key.

  D. Restrict access with User Management in Prism.

  Correct Answer: C

  Explanation: "An administrator has been tasked with increasing security on Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH, What is the easiest way for the administrator to meet these needs? Enable Cluster Lockdown and provide an RSA key." Cluster Lockdown mode disables password authentication when accessing the CVM and AHV hosts and instead requires key-based SSH. To enable Cluster Lockdown mode, you need to provide an RSA key. Therefore, by enabling Cluster Lockdown mode and providing an RSA key, you can increase security on Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH with minimal effort. https://next.nutanix.com/how-it-works-22/streamlined-login-and-increase-security-key- based-ssh-login-37397

• Question 120:

  When a configuring a syslog server in Prism Central, what two pieces information are required? (Choose two.)

  A. HTTPS URL

  B. Encryption secret

  C. Transport protocol

  D. IP address/port

  Correct Answer: CD
