The correct answer is E. /acct. 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.

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.

A/vs2/new_acct

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.

B/vs2/acct

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.

C/new_acct

'/new_acct' uses the volume name instead of the junction name 'acct'; ONTAP clients navigate by junction path, not by the underlying volume name.

D/vol/vs2/new_acct

'/vol/vs2/new_acct' is a legacy ONTAP 7-Mode path format and is not valid in clustered ONTAP SVM namespace addressing.

E/acctCorrect

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.
