NS0-162 Exam Dumps - Netapp Certified Data Administrator (NCDA) Questions and Answers

 You can use either XCP or the in-place conversion feature to move data from a FlexVol volume to a FlexGroup volume. XCP is a data migration tool that can copy data between different types of volumes, such as FlexVol and FlexGroup. The in-place conversion feature, introduced in ONTAP 9.7, allows you to convert a FlexVol volume to a FlexGroup volume without requiring a data copy or additional disk space. However, you cannot convert a FlexGroup volume back to a FlexVol volume. SnapMirror is not a valid option for this scenario, because it does not support replicating data from FlexVol to FlexGroup volumes. A FlexVol to FlexGroup conversion is supported, but only for transitioned volumes starting from ONTAP 9.8. References :- Converting FlexVol volumes to FlexGroup volumes overview, Can a FlexGroup be converted to a FlexVol?, Can I convert a Flexvol to FlexGroup without rewarming the tiered data?

The exhibit shows the details of VOL_A volume, including its IOPS allocations. The “Peak IOPS Allocation” is listed as “used-space,” and the “Expected IOPS” is 1000IOPS/TB. Since the size of VOL_A is 100GB (or 0.1TB), the expected IOPS would be 100, but it’s essential to consider that the “Absolute Minimum IOPS” is stated as 500IOPS/TB. However, since there’s no provided maximum limit in the exhibit, we can’t definitively state a maximum possible IOPS from this information alone. References :-The answer and explanation are inferred from the provided image as there’s no direct reference available in NetApp Data Administrator (ONTAP) documents and learning resources.

 The problem is that the NFS export policy only allows access to the IP range of 192.168.10.11-12, which does not include HOST 3’s IP address of 192.168.10.13. Therefore, the ESXi host cannot mount the NFS datastore. To solve the problem, you need to add HOST 3’s IP address to the NFS export policy, or modify the IP range to include it. This will grant the ESXi host the permission to access the NFS datastore. References :- ONTAP 9 Network Management Guide, ONTAP 9 NFS Reference, Troubleshooting NFS datastore connectivity issues (1003967)

The UTA2 ports are converged network adapters that can support either 10Gb Ethernet and FCoE or Fibre Channel modes. To use FCP over the UTA2 ports, there are two possible methods:

• Connect onboard UTA2 ports to a Nexus switch and enable FCP: This method allows the UTA2 ports to remain in the 10Gb Ethernet mode, but use the FCoE protocol to transport FC frames over the Ethernet network. The Nexus switch acts as a FCoE forwarder that bridges the FCoE traffic from the UTA2 ports to the FC fabric. This method requires the Nexus switch to support FCoE and the UTA2 ports to have the correct SFP+ transceivers for 10Gb Ethernet.
• Swap the Ethernet transceivers in the UTA2 ports for FC transceivers, and configure the ports as target ports: This method changes the UTA2 ports from the 10Gb Ethernet mode to the FC mode, which allows the UTA2 ports to directly connect to the FC fabric. This method requires the UTA2 ports to have the correct SFP+ transceivers for FC and the ports to be configured as target ports using the ucadmin command.

The other two options are not valid methods to use FCP over the UTA2 ports:

• Swap the Ethernet transceivers in the UTA2 ports for 1Gbps transceivers, and configure the ports as target ports: This method is not possible because the UTA2 ports do not support 1Gbps Ethernet mode. The UTA2 ports can only operate in 10Gb Ethernet or FC modes.
• Change the existing UTA2 ports from 10 Gbps speed to 8 Gb speed: This method is not possible because the UTA2 ports do not support changing the speed without changing the mode. The UTA2 ports can only operate in 10Gb Ethernet or FC modes, and the speed is determined by the mode and the transceiver type.

 Adaptive QoS is a feature that automatically adjusts the QoS throughput ceiling or floor based on the volume size, either used or allocated. The QoS throughput ceiling is the maximum number of IOPS or MB/s that a volume can consume. Therefore, any change that affects the volume size, such as adding data to the volume or resizing the volume, would affect the QoS throughput ceiling. Adding disks to the volume’s aggregate or having more clients access the volume would not affect the QoS throughput ceiling, as they do not change the volume size. References :- Use adaptive QoS policy groups, qos adaptive-policy-group create, Exam Name: NetApp Certified Data Administrator, ONTAP DEMO

IPspaces enable you to create multiple logical networks on a single physical network. Each IPspace contains a set of ports, broadcast domains, subnets, and routing groups that are isolated from other IPspaces. By using IPspaces, you can avoid IP address conflicts and routing issues when connecting to different networks that use the same or overlapping IP subnets. In this scenario, you can create a separate IPspace for the intercluster LIFs of AcmeClusOl and WidgetsClusOl, and assign them different subnets that do not overlap with the local subnet at your company. This way, the clusters can communicate with each other without interference from the local network traffic. References :- ONTAP 9 Network Management Guide, ONTAP 9 Cluster and SVM Peering Express Guide, ONTAP 9 Cluster and SVM Peering Guide
