How do you disable a specific version of NFS in a ZFS Storage Appliance?
A. Reduce the maximum number of concurrent NFS requests allowed.
B. Disable the NFSv4 delegation.
C. Set another NFS version number (the same version number) on both NFS minimum and maximum versions.
D. Enable iSNS discovery.
Correct Answer: C
Explanation/Reference:
Explanation:
NFS Service properties include:
Minimum supported version – Use this to control which versions of NFS the appliance supports.
Maximum supported version – Use this to control which versions of NFS the appliance supports.
Setting the NFS minimum and maximum versions to the same value causes the appliance to only communicate with clients using that version. This may be useful if you find an issue with one NFS version or the other (such as the performance characteristics of an NFS version with your workload), and you want to force clients to only use the version that works best.
Incorrect Answers:
B: Enable NFSv4 delegation – Select this property to allow clients to cache files locally and make modifications without contacting the server. This option is enabled by default and typically results in better performance; but in rare circumstances it can cause problems. You should only disable this setting after careful performance measurements of your particular workload and after validating that the setting has a measurable performance benefit. This option only affects NFSv4.0 and NFSv4.1 mounts.
