NS0-158 · Question #106

A customer has lost access to shares being used by an application. What are three troubleshooting steps the administrator should take? (Choose three.)

The correct answer is C. Verify that the LIFs in the SVM are all up and active. D. Verify that the SVM has CIFS running, that the share exists, and is online. E. Verify that there is network connectivity between the SMB client and the SVM.. When an application loses access to SMB/CIFS shares, the administrator should verify the status of relevant Logical Interfaces (LIFs), ensure the CIFS server and share are properly configured and online, and confirm network connectivity.

Question

A customer has lost access to shares being used by an application. What are three troubleshooting steps the administrator should take? (Choose three.)

Options

  • AVerify that the admin SVM is running on the node being accessed by the customer.
  • BVerify that the LIF resides on its home port.
  • CVerify that the LIFs in the SVM are all up and active.
  • DVerify that the SVM has CIFS running, that the share exists, and is online.
  • EVerify that there is network connectivity between the SMB client and the SVM.

Why each option

When an application loses access to SMB/CIFS shares, the administrator should verify the status of relevant Logical Interfaces (LIFs), ensure the CIFS server and share are properly configured and online, and confirm network connectivity.

AVerify that the admin SVM is running on the node being accessed by the customer.

The admin SVM is exclusively used for administrative tasks and does not serve data shares to end-user applications, making its operational status irrelevant to an application's data access.

BVerify that the LIF resides on its home port.

While LIFs typically prefer to reside on their home ports for optimal performance, a LIF not being on its home port does not necessarily prevent share access if it is still up and active on a non-home port.

CVerify that the LIFs in the SVM are all up and active.Correct

Logical Interfaces (LIFs) are the network access points for Storage Virtual Machines (SVMs); if the LIFs associated with the SVM are not up and active, clients will be unable to establish network connections to the shares.

DVerify that the SVM has CIFS running, that the share exists, and is online.Correct

For SMB/CIFS shares to be accessible, the CIFS server protocol must be running on the SVM, the specific share must exist, and its status must be online for clients to access it.

EVerify that there is network connectivity between the SMB client and the SVM.Correct

Network connectivity is fundamental for any client-server communication, so verifying the network path between the SMB client and the SVM's data LIF is a primary troubleshooting step to rule out network-related issues.
