A CIO has been reviewing the corporate BCDR plan. In this review, the CIO has noticed that they are replicating their Files deployments using the built in Files DR capabilities that are configured out of the box.
Upon further investigation, the CIO has identified that there are no granular share replications between their Files deployments and has requested the administrator to take an initiative and implement a granular Files Share recovery model.
Which Files capability should the administrator configure in order to be able to failover only certain shares?
- A. Smart Tiering
- B. Smart DR
- C. NC2 on AWS
- D. Data Lens
正解：B
解説：
Smart DR enables granular recovery of individual file shares in Nutanix Files by replicating data at the share level. This allows for more fine-grained control over the failover process and ensures that only critical data is recovered in the event of a disaster or outage.
Files Smart DR is a feature that allows you to replicate between Files instances, either on-premises or running on Nutanix Cloud Clusters on AWS1. With Files Smart DR, you can configure granular share replication, which means you can select which shares to replicate and which ones to exclude1. Therefore, the correct answer to your question is B. Smart DR.
Files Smart DR also supports replicating snapshots between the source share and its target, which can help with data recovery and compliance2. Additionally, Files Smart DR is the mechanism by which Files will support disaster recovery in the Nutanix Xi cloud3.

How should the administrator provide the required information?
- A. Go to Files, select the share used by the application and point to Usage View.
- B. Configure SNMP server with Nutanix MIBS and use Excel to analyze traps.
- C. Add a new' file category in File Analytics and use File Distribution View,
- D. Create a File Server Resource Manager MMC and use File Screens,
正解：C
解説：
According to File Auditing and Analytics for your Nutanix Files Enterprise Cloud1, File Analytics is a feature that captures real-time user audit data and file metadata for Nutanix Files environments. It allows you to create custom reports based on various criteria such as file type, size, owner, access time, etc.
According to Nutanix Files 3.8 and File Analytics 3.0 | Nutanix Community2, File Analytics allows you to add new file categories based on custom file extensions such as .zyx or .zzz. You can then use File Distribution View to see a collapsed view of space usage, number of files, and changes within a given time frame for each file category.
Therefore, if the administrator needs to analyze data created by a custom application that uses custom-built file extensions such as .zyx or .zzz, they can add a new file category in File Analytics and use File Distribution View to provide the required information.

Number of Departmental shares: 1
Everyone is permitted to accessing it
All users use the same Departmental share
The administrator deploys Files using the following configuration:
Number of FSVMs: 3
VCPU & RAM/FSVM: 4VCPU,12GB
One Distributed share with SSR & ABE enabled for the Home Directories
One Standard share for the Departmental share
Does this configuration satisfy the project's requirements?
- A. Yes, the listed configuration elements satisfy the requirements.
- B. No, the project needs 4 FSVMs 4 vCPU & 12GB RAM.
- C. No, the project needs two distributed 4 FSVMs, 24 vcpu & 128GB RAM
- D. No, the project needs two distributed Share 4 FSVMs. 6 vCPU & 326B RAM
正解：A
解説：
According to the scenario, the administrator is preparing to migrate data from a legacy storage environment to a new Files scale-out file server in a way that meets the following requirements:
Number of home directories: 4000
Number of Departmental shares: 1
Everyone is permitted to access it
All users use the same Departmental share
The administrator deploys Files using the following configuration:
Number of FSVMs: 3
VCPU & RAM/FSVM: 4VCPU, 12GB
One Distributed share with SSR & ABE enabled for the Home Directories
One Standard share for the Departmental share
Based on this configuration, it appears that the project's requirements are satisfied. The configuration provides a Distributed share for the home directories, which is recommended when there is a large number of files or directories, and this will distribute the load across multiple FSVMs. Note that everyone is permitted to access it.
In addition, the configuration provides a Standard share for the Departmental share, and since all users use the same Departmental share, this will not create any performance issues. Therefore, the correct answer is B, 'Yes, the listed configuration elements satisfy the requirements'.

An administrator is implementing a storage solution with these requirements:
Is easily searchable
Natively supports disaster recovery
Access to each item needs to be fast
Can scale to petabytes of data
users are granted access after authentication
user data is isolated, but could be shared
How should the administrator satisfy these requirements?
- A. use Files distributed share with ABE.
- B. Configure Calm with an application per user.
- C. Deploy Objects with AD integration.
- D. Implement Volumes with CHAP.
正解：C
解説：
This is because Objects can provide fast access to each item using S3-compatible API which can be easily searched using metadata tags or third-party tools3. Objects also natively supports disaster recovery using replication policies1. Objects can scale to petabytes of data using erasure coding which reduces storage overhead1. Users can be granted access after authentication using AD integration which simplifies identity management1. User data can be isolated but could be shared using buckets which are logical containers for objects that can have different policies applied1.
質問 # 53
A company uses a Nutanix 3-node cluster environment. In Prism Pro, the Capacity Runway shows these capacity values:
Max Capacity: 6 TiB
Effective Capacity 4 TiB
The company wants to upgrade the environment to use an RF3 container and also requires all cluster nodes to be the same model, What must the effective capacity Of the Nutanix cluster be to support the new RF3 container?
- A. 9 TiB
- B. 4 TiB
- C. 6 TiB
- D. 10 TIB
正解：A
解説：
To support a new RF3 container, the effective capacity of the Nutanix cluster must be at least three times the size of the data that needs to be stored on it3. This is because RF3 means that each data block is replicated three times across different nodes or blocks for fault tolerance3.
This is because if you have 4 TiB of effective capacity with RF2 (which means each data block is replicated twice), then you need 9 TiB of effective capacity with RF3 (which means each data block is replicated three times).
質問 # 54
Which setting should the administrator apply to a newly-created Objects bucket to ensure the requirements are met?
- A. Apply a bucket Lifecycle Policy with a one-year expiration.
- B. Configure the bucket WORM policy with a one-year retention,
- C. Configure a Lifecycle Policy to overwrite one-year old data in the bucket.
- D. Apply an Object versioning policy with one-year retention.
正解：B
質問 # 55
An administrator needs to configure a Files share with these requirements:
Supports 100 virtual desktop users
Share would host user data
Share is limited to 1 TB, evenly distributed across users
Optimized for best I/0 performance within the current environment
Which two configuration actions should the administrator take to meet these requirements? (Choose two.)
- A. Add a quote policy to the share.
- B. Enable ABE on the share.
- C. Create a distributed share.
- D. Configure a standard share.
正解：A、C
解説：
According to Nutanix Files SMB Share Default Permission1, a standard share is created with default permissions for three built-in groups: Administrators, Users, and Backup Operators. This may not be suitable for hosting user data that needs to be evenly distributed across users.
According to Nutanix Support & Insights2, a distributed share is a type of SMB share that allows you to distribute files across multiple file servers for better performance and scalability. This can help optimize the I/O performance within the current environment.
According to Nutanix File and NFS Mount Examples3, a quota policy is a way to limit the amount of space that a user or group can consume on a share. This can help enforce the 1 TB limit on the share and ensure that each user gets an equal amount of space.

質問 # 56
An existing Objects bucket was created for backups with these parameters:
A) WORM policy of three years
B) Versioning policy of two years
C) Lifecycle policy of two years
The customer reports that the cluster is nearly full due to backups created during a recent crypto locker attack. The customer would like to automatically delete backups older than one year to free up space in the cluster.
How should the administrator change settings within Objects?
- A. Modify the existing bucket WORM policy from three years to one year.
- B. Create a new' bucket with the lifecycle policy of one year.
- C. Create a new' bucket with the WORM policy of two years.
- D. Modify the existing bucket lifecycle policy from two years to one year.
正解：D
解説：
According to Nutanix documentation on unified storage (NCP-US) v6, to automatically delete backups older than one year, an administrator should modify the existing bucket lifecycle policy to set the expiration period to one year. Lifecycle policies enable administrators to automate the transition of objects to different storage classes and to expire them altogether. In this scenario, modifying the existing bucket lifecycle policy to shorten the expiration period to one year will ensure that backups older than one year are automatically deleted to free up space in the cluster.

質問 # 57
During a recent audit, the auditors discovered several shares that were unencrypted. To remediate the audit item, the administrator enabled Encrypt SMB3 Messages on the accounting, finance, and facilities shares. After encryption was enabled, several users have reported that they are no longer able to access the shares.
What is causing this issue?
- A. Advanced Encryption Standard 128 & 256 are disabled in Windows 7.
- B. The users are accessing the shares from Windows 8 desktops.
- C. Advanced Encryption Standard 128 & 256 are disabled in Linux or Mac OS.
- D. The users are accessing the shares from Linux desktops.
正解：D
解説：
According to Encryption-Files | Nutanix Community1, SMB3 message encryption is a feature that encrypts messages on the file server side and decrypts them on the client side. However, clients that do not support encryption (Linux, Mac, windows 7) cannot access a share with encryption enabled.
According to Nutanix Support & Insights2, Nutanix Files supports SMB3 encryption for SMB3 client-server traffic. This means that only clients that support SMB3 protocol can access encrypted shares.
Therefore, if the users are accessing the shares from Linux desktops, they will not be able to access them because Linux does not support SMB3 encryption.

質問 # 58
An administrator successfully installed Objects and was able to create a bucket.
When using the reference URL to access this Objects store, the administrator is unable to write data in the bucket when using an Active Directory account.
Which action should the administrator take to resolve this issue?
- A. Verify Access Keys for the user.
- B. Reset Active Directory use's password
- C. Replace SSL Certificates at Objects store level.
- D. Verify sharing policies at buckets level.
正解：D
解説：
According to Nutanix Objects User Guide1, "Objects supports Active Directory (AD) authentication for users and groups that are part of an AD domain." However, "To access a bucket using AD credentials, you must have permissions on that bucket." Therefore, the administrator should verify that the sharing policies for the bucket allow access for the AD account.
質問 # 59
Why should an administrator avoid allocating over half the RAM on a host to a FSVM?
- A. The FSVM would experience host swapping of memory.
- B. The FSVM would be in a single NUMA node boundary.
- C. The FSVM has a set memory configuration.
- D. The FSVM would cross NUMA node boundaries.
正解：D
解説：
The administrator should avoid allocating over half the RAM on a host to a FSVM because the FSVM would cross NUMA node boundaries (option A).
NUMA (Non-Uniform Memory Access) is a memory architecture that divides the system memory into multiple regions that are assigned to different processors or cores.
If a FSVM crosses NUMA node boundaries, it will have to access memory from different regions, which will result in higher latency and lower performance for file operations.
To avoid this issue, the administrator should ensure that the FSVM memory allocation is within a single NUMA node boundary.
質問 # 60
An administrator has mapped a Volume Group named VGI to a VM, Due to changes in the application running inside the VM, two additional volumes are required. At the time of creation, the VM was assigned to a Protection Domain named PDI.
Which two steps should the administrator take to add the additional volumes to the VM while maintaining data protection? (Choose two.)
- A. Add the new vDisks to the same Consistency Group.
- B. Add two additional vDisks to VG1.
- C. Manually update PD1 to include the newly created vDisks.
- D. Map the new vDisks as volumes to the VM.
正解：A、B
解説：
To add additional volumes to a VM that is mapped to a VG, you need to add more vDisks to that VG1. vDisks are virtual disks that reside on Storage Containers2.
To maintain data protection for a VM that is assigned to a Protection Domain (PD), you need to add any new vDisks to the same Consistency Group (CG) as the existing ones3. A CG is a subset of entities in a PD that are snapshotted in a crash-consistent manner2.
質問 # 61
An administrator is determining the most recent operation a user performed on the share cifs1 within the last 24 hours.
How should the administrator complete this task in File Analytics?
- A. In the Anomalies section view the anomaly rule created for the user with an interval of 24 hours.
- B. In the Anomalis section. select Users exceed an operation count threshold an input the 24 hour range for share cifs1.
- C. In the Audit Trails section, search for the cifs1 share and view the actions on the share over the past 24-hour range.
- D. In the Audit Trails section, search for the user and view their last operations.
正解：C
解説：
File Analytics is a tool used for monitoring and auditing file activity within an organization's file servers. The administrator needs to determine the most recent operation a user performed on the share cifs1 within the last 24 hours. To accomplish this task in File Analytics, the administrator should go to the Audit Trails section, where they can search for the cifs1 share and view the actions on the share over the past 24-hour range. This will allow the administrator to see all the activity that has occurred on the share, including the most recent operation performed by the user.
According to the Nutanix Unified Storage v6 documents at nutanix.com1, File Analytics captures all file activity for registered file server instances and provides an audit trail for administrators2. In the Audit Trails section, you can search for the user or the share name and view their operations over a specified time range2. This would allow you to determine the most recent operation a user performed on the share cifs1 within the last 24 hours.
質問 # 62
In a Nutanix cluster based on AHV, multiple Nutanix unified Storage services such as Volumes, Files and Objects are deployed. After performing an LCM inventory, MSP is listed as an update.
Which storage service requires MSP to be updated?
- A. Objects
- B. Volumes
- C. Files
- D. Prism
正解：A
解説：
"Kubernetes is not correctly reporting its storage usage." The NCC checks run on the nodes in the cluster and may report storage usage differently based on how they are being executed. Additionally, the administrator notes that the Kubernetes pod reports that the usage is 55% used disk space, which is different than what the NCC checks report.
One possible cause of this discrepancy is that Kubernetes is not correctly reporting its storage usage. It is recommended that the administrator checks the Kubernetes storage configuration to ensure it is set up correctly and that Kubernetes is able to accurately report the storage usage. It may also be necessary to update or reinstall Kubernetes if there are any issues with the installation.
Nutanix Objects is a software-defined object storage solution that provides scalable and secure data storage for unstructured data1. MSP is responsible for routing requests from clients to Objects clusters and providing load balancing and high availability1. To update MSP, you need to perform an LCM inventory and select MSP from the software updates list1.
