Netapp NS0-155 - Data ONTAP 7-Mode Administrator

https://library.netapp.com/ecmdocs/ECMP1196890/html/man5/na_exports.5.html

The /etc/exports file contains a list of export entries for all file system paths that Data ONTAP exports automatically when NFS starts up.

This question is out of date, but its still on the exam as of Sept2013! NOW has been replaced with support.netapp.com.

You should be very familiar with what AutoSupport does. Also if you have done any research, you know that the System Configuration Guide is an invaluable tool that you will use regularly. Neither of those are related to bugs.

Bugs Online (BOL) is located at http://support.netapp.com/NOW/cgi-bin/bol/ Bugs Online provides a suite of tools to help manage and resolve your bug issues.

Only hostnames and IPs are referenced in /etc/hosts, so A is incorrect. The question states that the qtree was mounted, and B and D would preclude this so they are incorrect.

You need to set a qtree to mixed or unix security style to support UNIX users.

The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a trace buffer then dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump" format, and can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also be converted using the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

To upgrade an aggregate in-place, the only available method is to add disks to expand the aggregate to >16TB.

Reverting a file to a selected Snapshot copy

Using snap restore to revert a single file to a selected Snapshot copy is practical when the file is so large that you cannot copy the previous file version from the Snapshot copy to the active file system.

Before you begin Ensure that you notify the network users before reverting a file so that they know that the current data in the file will be replaced by that of the selected Snapshot copy.

Note: NFS users who try to access a reverted file without first reopening it might get a stale file handle error message after the volume reversion.

In OnTap 8.0, when UNIX security style is selected, only UNIX security objects can be used. The correct answer is GID, UID and UNIX permissions.

Basic UNIX permissions are organized into three classes: user, group, and others.

UNIX operating systems identify users with a numerical value: a user identifier, also known as a UID or User ID. Each user is a member of a group of the same name as the user. Like UIDs, groups (GIDs) are also specified using a numerical value.

fcp show adapter [ -v ] [ adapter ]

If no adapter name is given, information about all adapters are shown.

This command displays information such as nodename/portname and link state about the adapter.

If the -v flag is given, this command displays additional information about the adapters.
