The most efficient way to generate a report listing the files matching those in the exhibit is to use Report Builder in File Analytics. Report Builder is a feature that allows administrators to create custom reports based on various filters and criteria, such as file name, file type, file size, file owner, file age, file access time, file modification time, file permission change time, and so on. Report Builder can also export the reports in CSV format for further analysis or sharing. Reference: Nutanix Files Administration Guide, page 97; Nutanix File Analytics User Guide

The two steps that the administrator should perform to resolve the connectivity issues with the domain controller servers are:
Verify the DNS settings in Prism Element: DNS (Domain Name System) is a system that translates domain names into IP addresses. DNS settings are configurations that specify which DNS servers to use for resolving domain names. Verifying the DNS settings in Prism Element is a step that the administrator should perform, because it can help identify and correct any incorrect or outdated DNS server addresses or domain names that may cause connectivity issues with the domain controller servers.
Verify the DNS entries for the given domain name: DNS entries are records that map domain names to IP addresses or other information. Verifying the DNS entries for the given domain name is another step that the administrator should perform, because it can help check and update any incorrect or outdated IP addresses or other information that may cause connectivity issues with the domain controller servers.
