NS0-162 Exam Dumps : NetApp Certified Data Administrator (ONTAP)

 According to the NetApp best practices, flow control should be disabled on data network ports and cluster network ports using 10GbE Ethernet. This is because flow control can cause excessive pause frames, xon/xoff frames, or packets being re-queued, which can affect the network performance and TCP throughput. Flow control works at the physical link layer and does not consider the upper level protocols. Therefore, it is recommended to disable flow control end-to-end on both data and cluster network ports for optimal performance. References :- How to modify flow control on cluster port in ONTAP, What are the flow control best practices for Ethernet?, Configure your network for best performance

 The number of ISCSI LIFs that will be created from the SVM setup wizard, as shown in the exhibit, is 16. This is because the LIFs per node field is set to 2, and there are 4 nodes in the cluster. Therefore, the total number of LIFs is 2 x 4 8 for each SVM, and since there are two SVMs, the total number of LIFs is 8 x 2 16. The other options are incorrect because they do not match the calculation based on the exhibit. References :- Configure an SVM for iSCSI, Configure iSCSI on an existing SVM

When you perform an upgrade using ONTAP System Manager 9.8, you can use the automated nondisruptive update (ANDU) feature, which simplifies and streamlines the update process. The latest available images will appear in the ONTAP System Manager interface, and you can select the image you want to install. The update history is available within the ONTAP System Manager interface, and you can view the status and progress of the update. You do not need to manually upload the images to the cluster or download them from the NetApp Support site, as ONTAP System Manager will automatically download and upload the images as needed. References :- Automated nondisruptive ONTAP upgrade, How to Upgrade to ONTAP 9.8
