Which action does the DISALLOW_SERVER_FILE_WRITES in a Client’s configuration perform?

The correct answer is A. The DISALLOW_SERVER_FILE_WRITES client configuration entry controls whether NetBackup servers are allowed to write files on the client host. Cohesity NetBackup documentation states that this entry “prevents the NetBackup server from creating files on the NetBackup server or client” and further explains that it prevents NetBackup servers from remotely performing restores or remotely changing client configurations. In practical administration terms, this disables server-directed restores to that client. Cohesity also maps the related Windows Backup, Archive, and Restore interface setting to File > NetBackup Client Properties > Allow server-directed restores, confirming that the function is specifically about whether restores can be initiated from the NetBackup server side toward the client. This is why option A is the best match. Option B refers to redirected restores, which are governed by alternate-client restore permissions and client authorization behavior, not this setting alone. Option C is too broad because client-initiated restore capability is controlled separately, such as by DISALLOW_CLIENT_RESTORE. Option D is unrelated to backup write permission.
