• Question 22:

  Which metric is utilized when sizing a Files deployment based on performance requirements?

  A. Quantity of SMB shares

  B. SMB concurrent connections

  C. NFS concurrent connections

  D. Quantity of NFS exports

  Correct Answer: B

  Explanation: This metric indicates the number of active clients that are accessing the Files cluster via SMB protocol, which affects the performance of the Files cluster. NFS concurrent connections is also a relevant metric, but it is not the best answer, as it only applies to NFS protocol, not SMB. The quantity of SMB shares or NFS exports does not directly affect the performance of the Files cluster, as they are logical entities that do not consume resources.

• Question 23:

  A Files administrator needs to generate a report listing the files matching those in the exhibit.

  What is the most efficient way to complete this task?

  A. Use Report Builder in File Analytics.

  B. Create a custom report in Prism Central.

  C. Use Report Builder in Files Console.

  D. Create a custom report in Files Console.

  Correct Answer: A

  Explanation: The most efficient way to generate a report listing the files matching those in the exhibit is to use Report Builder in File Analytics. Report Builder is a feature that allows administrators to create custom reports based on various filters and criteria, such as file name, file type, file size, file owner, file age, file access time, file modification time, file permission change time, and so on. Report Builder can also export the reports in CSV format for further analysis or sharing. References: Nutanix Files Administration Guide, page 97; Nutanix File Analytics User Guide

• Question 24:

  An administrator is required to place all iSCSI traffic on an isolated network.

  How can the administrator meet this requirement?

  A. Create a new network interface on the CVMs via ncli.

  B. Create a Volumes network in Prism Central.

  C. Configure network segmentation for Volumes.

  D. Configure the Data Services IP on an isolated network.

  Correct Answer: C

  Explanation: The administrator can meet this requirement by configuring network segmentation for Volumes. Network segmentation is a feature that allows administrators to isolate network traffic for different types of services, such as Volumes, Files, or Objects, on a Nutanix cluster. Network segmentation can improve the security, performance, and manageability of network traffic. By configuring network segmentation for Volumes, the administrator can place all iSCSI traffic on an isolated network and prevent it from interfering with other services or applications.

• Question 25:

  What is the most efficient way of enabling users to restore their files without administrator intervention in multiple Files shares?

  A. Click Enable next to the name of the share in Manage Recovery Settings from Data Lens.

  B. Click Enable Self Service Restore in the Edit wizard for each share in Shares tab from Files Console.

  C. Assign the same Category to all FSVMs and adding that Category to a single Protection Policy in PC.

  D. Add all FSVMs to a Consistency Group within a single asynchronous Protection Domain in PE.

  Correct Answer: B

  Explanation: Nutanix Files allows users to restore their files from the snapshots taken by the protection policy. A protection policy is a set of rules that defines how often snapshots are taken, how long they are retained, and where they are replicated. A protection policy can be applied to one or more file shares. To enable users to restore their files without administrator intervention, the administrator must enable the Self Service Restore option for each share in the Files Console. This option adds a hidden folder named .snapshot in each share, which contains all the snapshots taken by the protection policy. Users can access this folder and browse the snapshots to find and restore their files. The administrator can also configure the permissions and quota for the .snapshot folder.

• Question 26:

  After configuring Smart DR, an administrator is unable see the policy in the Policies tab. The administrator has confirmed that all FSVMs are able to connect to Prism Central via port 9440 bidirectional.

  What is the possible reason for this issue?

  A. The primary and recovery file servers do not have the same protocols.

  B. Port 7575 should be open for all External/Client IPS of FSVMs on the Source and Target cluster.

  C. The primary and recovery file servers do not have the same version.

  D. Port 7575 should be open for all Internal/Storage IPs of FSVMs on the Source and Target.

  Correct Answer: B

  Explanation: Smart DR is a feature that allows share-level replication between active file server instances for disaster recovery. To configure Smart DR, one of the prerequisites is to open TCP port 7575 for all External/Client IPs of FSVMs on the Source and Target cluster. This port is used for communication between the FSVMs and Prism Central. If this port is not open, Smart DR policies will not be visible in the Policies tab in Prism Central.

• Question 27:

  An administrator is tasked with performing an upgrade to the latest Objects version.

  What should the administrator do prior to upgrade Objects Manager?

  A. Upgrade Lifecycle Manager

  B. Upgrade MSP

  C. Upgrade Objects service

  D. Upgrade AOS

  Correct Answer: D

  Explanation: Before upgrading Objects Manager, the administrator must upgrade AOS to the latest version. AOS is the core operating system that runs on each node in a Nutanix cluster and provides the foundation for Objects Manager and Objects service. Upgrading AOS will ensure compatibility and stability for Objects components. References: Nutanix Objects Administration Guide, Acropolis Operating System Upgrade Guide

• Question 28:

  Deploying Files instances require which two minimum resources? (Choose two)

  A. 12 GiB of memory per host

  B. 8 vCPUs per host

  C. 8 GiB of memory per host

  D. 4 vCPUs per host

  Correct Answer: CD

  Explanation: The two minimum resources that are required for deploying Files instances are 8 GiB of memory per host and 4 vCPUs per host. Memory and vCPUs are resources that are allocated to VMs (Virtual Machines) to run applications and processes. Files instances are file server instances (FSIs) that run on FSVMs (File Server VMs) on a Nutanix cluster. FSVMs require at least 8 GiB of memory and 4 vCPUs per host to function properly and provide SMB and NFS access to file shares and exports. The administrator should ensure that there are enough memory and vCPUs available on each host before deploying Files instances.

• Question 29:

  Users are complaining about having to reconnecting to share when there are networking issues.

  Which files feature should the administrator enable to ensure the sessions will auto- reconnect in such events?

  A. Durable File Handles

  B. Multi-Protocol Shares

  C. Connected Shares

  D. Workload Optimization

  Correct Answer: A

  Explanation: The Files feature that the administrator should enable to ensure the sessions will auto-reconnect in such events is Durable File Handles. Durable File Handles is a feature that allows SMB clients to reconnect to a file server after a temporary network disruption or a client sleep state without losing the handle to the open file. Durable File Handles can improve the user experience and reduce the risk of data loss or corruption. Durable File Handles can be enabled for each share in the Files Console.

• Question 30:

  An administrator has performed an AOS upgrade, but noticed that the compression on containers is not happening.

  What is the delay before compression begins on the Files container?

  A. 30 minutes

  B. 60 minutes

  C. 12 hours

  D. 24 hours

  Correct Answer: C

  Explanation: The delay before compression begins on the Files container is 12 hours. Compression is a feature that reduces the storage space required for data by applying an algorithm that eliminates redundant or unnecessary bits. Compression can improve the storage efficiency and performance of Files. Compression is enabled by default on the Files container and runs in the background as a low-priority task. Compression does not start immediately after an AOS upgrade, but waits for 12 hours to avoid interfering with other high-priority tasks or operations.
