Question
A volume is created named "new_acct" in a data vserver named vs2. A junction for this volume is created named "acct" from the root of vs2. This namespace will be mounted on a Linux host. What is the path that the Linux host needs to mount?
Options
- A/vs2/new_acct
- B/vs2/acct
- C/new_acct
- D/vol/vs2/new_acct
- E/acct

Why each option
In ONTAP clustered mode, the NFS mount path for a Linux client is the junction name relative to the SVM namespace root, not the SVM name or volume name.
The SVM name 'vs2' is not part of the NFS export path; ONTAP does not prepend the SVM name to namespace paths presented to clients.
Like option A, prepending '/vs2/' is incorrect - the SVM identity is reflected in the LIF IP used to connect, not in the export path string.
'/new_acct' uses the volume name instead of the junction name 'acct'; ONTAP clients navigate by junction path, not by the underlying volume name.
'/vol/vs2/new_acct' is a legacy ONTAP 7-Mode path format and is not valid in clustered ONTAP SVM namespace addressing.
When a junction named 'acct' is created at the root of SVM vs2, the SVM namespace root is presented to NFS clients as '/'. The junction path is therefore simply '/acct'. The Linux host mounts the SVM data LIF IP with '/acct' as the export path, which directly resolves to the junction and the underlying 'new_acct' volume.
