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

 Temperature Sensitive Storage Efficiency (TSSE) is a method of compressing data based on data “temperature”, or how often the data is used. “Cold” data, or data that is not used often, is recompressed with a higher compression ratio for increased storage efficiency. TSSE is enabled automatically on newly created thinly provisioned AFF volumes, not thick provisioned volumes. TSSE operations on AFF arrays are automatically throttled depending on whether data is hot or cold, to balance performance and efficiency. TSSE is not supported on Cloud Volumes ONTAP or ONTAP Select, as these platforms have different storage characteristics and requirements. References :- Temperature-sensitive storage efficiency overview, How does Temperature Sensitive Storage Efficiency affect SnapMirror?, ONTAP Temperature Sensitive Storage Efficiency (TSSE) – A Simple Introduction

The auto-revert option determines whether a LIF automatically reverts to its home port after a failover event. If this option is set to true, the LIF will revert to its home port when it becomes available. If this option is set to false, the LIF will remain on the failover port until manually reverted. In this scenario, the cluster LIFs are not on their home ports after an ONTAP upgrade, which might have triggered a failover event. Therefore, setting the auto-revert option to true would change this outcome and ensure that the LIFs return to their home ports after the upgrade. References :- network interface modify, Verify all LIFS are on home ports after ONTAP upgrade

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
