Nutanix NCS-CORE Online Questions & Answers

• Question 81:

  An administrator finds that home shares cannot be configured in a new Files 3.5 deployment. Why is this happening?

  A. NFS default access is set to Read Only.
  B. Multi-protocol access is not configured.
  C. Access Based Enumeration is not enabled.
  D. The system is deployed as a single FSVM.
  D. The system is deployed as a single FSVM.

• Question 82:

  To ensure VM availability when a service outage has occurred, a customer has requested that automatic VM failovers must occur as part of the DR strategy for their environment.

  Which failover operation is within an Unplanned Failover option?

  A. AHV Metro - with Witness Operation
  B. Protection Domain Migrate
  C. Cross-Cluster Live Migration
  D. Test Failover
  A. AHV Metro - with Witness Operation

  ---

  Explanation/Reference:

  For scenarios requiring VM availability during unplanned outages, AHV Metro with Witness Operation is designed to handle such situations. AHV Metro Availability enables synchronous replication between two sites with a witness that

  arbitrates site availability in case of a split-brain scenario. This setup is intended for automatic failover during service disruptions, ensuring continuous availability of VMs without manual intervention.

• Question 83:

  An administrator manages the following two Nutanix AOS 5.15 cluster environment:

  1.

  Corp-cluster-01

  2.

  Corp-cluster-02

  The VM images must be available only on Corp-cluster-01, but cannot be checked out to cluster Corp-cluster-02. The images also cannot be checked out to any other clusters that are registered with Prism Central in the future.

  Which two configuration settings must the administrator choose when creating the image placement policy that satisfies the stated requirements? (Choose two.)

  A. Create an image placement policy that identifies cluster Corp-cluster-01 as the target cluster
  B. Set the policy enforcement to Soft.
  C. Set the policy enforcement to Hard.
  D. Create an image placement policy that identifies cluster Corp-cluster-02 as the target cluster.
  A. Create an image placement policy that identifies cluster Corp-cluster-01 as the target cluster
  C. Set the policy enforcement to Hard.

  1.

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

  2.

  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?

  A. 0 minutes
  B. 15 minutes
  C. 1 hour

• Question 85:

  What should a consultant consider when completing a bare-metal imaging process?

  A. Avoid connecting any device to the node USB port that presents virtual media such as a CD-ROM.
  B. Connect to a managed switch with routing tables to protect the production environment against configuration errors.
  C. Ensure that the CD ROM appears last in the BIOS boot order to avoid Foundation timeout.
  D. Enable STP by using PortFast or an equivalent feature on the ports that are connected to the Nutanix host.
  A. Avoid connecting any device to the node USB port that presents virtual media such as a CD-ROM.

  ---

  Explanation/Reference:

  When completing a bare-metal imaging process, it is crucial to avoid connecting any device to the node's USB port that presents virtual media such as a CD-ROM. This is important because such devices can interfere with the imaging

  process, potentially leading to errors or misconfigurations by presenting alternative boot options or media.

• Question 86:

  Which subnet should a consultant be aware is reserved for internal connectivity within a Nutanix cluster?

  A. 192.168.5.0/24
  B. 192.168.5.0/23
  C. 192.168.254.0/24
  D. 192.168.5.0/26
  A. 192.168.5.0/24

  ---

  Explanation/Reference:

  The consultant should be aware that the subnet 192.168.5.0/24 is reserved for internal connectivity within a Nutanix cluster. This subnet is typically used for the internal operations of the Nutanix cluster, including CVM backplane communications. It is critical to ensure that this subnet does not overlap with any external network configurations to avoid networking conflicts that can affect cluster operations and communications.References: Nutanix Networking Best Practices, Nutanix Cluster Configuration Guide.

• Question 87:

  Refer to the exhibit.

  

  What is the purpose of eth2 on the CVMs?

  A. RDMA Network Segmentation
  B. iSCSI connectivity
  C. Remote site connectivity
  D. Network Segmentation
  D. Network Segmentation

• Question 88:

  A consultant deployed a Nutanix Files cluster using separate networks for client and storage.

  For testing a SMB standard share, a VM has been deployed on storage network. However, the consultant cannot access the share.

  What is the cause of the issue?

  A. The CVM network segmentation is configured.
  B. Clients on the same subnet as the storage network cannot access the shares.
  C. An iSCSI Data Services IP is not configured for the cluster.
  D. Clients on the same subnet as the storage network can only access the distributed shares.
  B. Clients on the same subnet as the storage network cannot access the shares.

  ---

  Explanation/Reference:

  If a VM deployed on the storage network cannot access a SMB standard share, the likely issue is that:

  Clients on the same subnet as the storage network cannot access the shares: This scenario typically occurs due to network segmentation policies or firewall rules that restrict access to the storage network from clients within the same subnet,

  intended to segregate traffic types for security and performance reasons.

  related to file access.

• Question 89:

  Which Nutanix feature creation is described in the Knowledge Transfer?

  A. Calm Blueprints
  B. REST API
  C. Self Service Portal
  D. Data Protection Domain
  A. Calm Blueprints

  ---

  Explanation/Reference:

  The Nutanix feature that involves creation as described in the Knowledge Transfer is "Calm Blueprints." Nutanix Calm provides application automation and lifecycle management capabilities that are reflected in Calm Blueprints. These blueprints define the application's architecture, such as services, dependencies, and associated metadata, and are used to automate the provisioning and scaling of applications across multiple environments, making them a critical component in the Nutanix ecosystem for simplifying management and operations of applications.References: Nutanix University, Nutanix Calm User Guide.

• Question 90:

  An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers. An investigation of the issue finds:

  1.

  The time on all CVMs is the same

  3.

  Both the CVMs and AHV hosts are configured for the UTC time zone Which two steps can be taken to troubleshoot this issue? (Choose two.)

  A. Confirm that the NTP servers are reachable from the CVMs.
  B. Restart genesis on all CVMs.
  C. On a CVM. run the command a Hash ntpq -pn.
  D. Restart the chronos service on all CVMs.
  A. Confirm that the NTP servers are reachable from the CVMs.
  C. On a CVM. run the command a Hash ntpq -pn.
