An iSCSI or FC SAN implementation provides _____ access to LUNs.
You are having problems accessing three recently-created LUNs. Given the output below, the reason is because all of the LUNs are using the same LUN ID of 0. lun show -m LUN path Mapped to LUN ID -------------- ------------------ ------------------- /vol/vol1/lun0 solaris-igroup 0 0 /vol/vol1/lun1 windows-igroup 0 /vol/vol1/qtree1/lun2 aix-igroup 0 /vol/vol1/qtree1/lun3 linux-igroup 0
Before running lun setup on the storage system, you must first create the igroup to which the initiator will be attached.
Which command would you use to verify that the iSCSI service is running?
____________ is the default cfmode for new installations of Data ONTAP 7.3.
Which iSCSI security method encrypts data between the initiator and the target?
Which three commands would help you troubleshoot a LUN that cannot be accessed by a host? (Choose three.)
lun show -v
fcp show initiator
Physical Reallocation of a SnapMirror source volume increases the amount of data to transfer for the next SnapMirror update.
To automatically export volumes and directories on reboot, include them in the /etc/exports file.
To determine if a problem you are experiencing is known to NetApp, use the NOW site _____ utility.
Bugs Online/Release Comparison
Which two commands on the storage system allow you to gather statistics about network interfaces, including basic information about network connections? (Choose two.)
Which two commands can be used to enable LUN reservations? (Choose two.)
lun set reservation
Which three can coexist on a NetApp storage system? (Choose three.)
What are 3 true statements about physical reallocation of data added in ONTAP 7.3? (Choose three.)
Volume Snapshots do not need to be deleted for the reallocate to run effectively
Dont run it on files, volumes, and LUNs that are in an aggregate created by a version of ONTAP earlier than 7.2
Use reallocate -p pathname to run the physical reallocate
Which command on the storage system allows you to collect statistics on the performance of system resources such as CPU, NVRAM, network interfaces, and disks?
If the security style is set to UNIX, CIFS client file access is determined by ___________ .
the mapped UNIX UID/GID of the CIFS client and the UNIX file permissions
To configure a storage system as a member of a Windows active directory domain, the time on the storage system must be set to be within plus or minus five minutes of the time on the domain controller.
Which two conditions might cause a user to receive a disk full message from a storage system? (Choose two.)
A volumes active file system size could not be provided.
The user has reached her assigned quota.
Two alternatives to guaranteeing LUN space reservations during a snapshot on a volume with fractional reserve set to 0% can be: (Choose two.)
Which two statements about hard and soft zoning are correct? (Choose two.)
Soft zones separate devices at the name service level.
Hard zoning physically restricts access to only members of that zone.
To view per client NFS statistics on a storage system, the option nfs.per_client_stats.enable must be set on.
Which two operations can be performed with the SnapDrive for Windows graphical user interface? (Choose two.)
Which command displays the statistics for Ethernet network interfaces?
When viewing the output of the sysstat -f 1 command, which three fields are part of the total number of operations per second? (Choose three.)
UNIX allows file access based on __________.
GID or UID and UNIX permissions.
Which two are Data ONTAP commands for gathering performance information? (Choose two.)
These are three methods of creating a LUN: * lun setup * lun map * FilerView
CIFS clients can resolve symbolic links created by NFS clients on the storage system.
Which storage system command would display the WWPNs of hosts that have logged into a storage system using a Fibre Channel connection?
fcp show initiator
Which entry in this /etc/quotas file for a qtree on /vol/wmv will affect the target?
The first entry for the qtree.
Executing this command will have what effect? options wafl.default_security_style mixed
It will set the default security style for all newly created volumes.
If you change the setting for the option cifs.neg_buf_size, you need to terminate CIFS on the storage system and do a restart for the changes to take effect.
When running deduplication on SnapVault destinations, which 3 statements are true?
The source (primary) system sends duplicated data even if the source data is deduplicated.
Deduplication internally synchronizes with the SnapVault schedule on the destination.
Deduplication with SnapVault creates a snapshot, deduplicates, then deletes and recreates the snapshot to effectively deduplicate savings.
Which command is used to set the configuration of an Ethernet network interface?
A quota target can be applied to _______________.
a user group, or qtree
In Data ONTAP, both the Microsoft Windows Administrator and root are exempt from user and group quotas, but not from tree quotas.
NTFS allows file access based on ___________.
NT ACLs and SID.
Starting with Data ONTAP 7.3.1, support for SMB 2.0 in Windows Vista and Windows Server 2008 was added.
The super user receives an "Access Denied" message when he attempts to mount the new qtree. Whats the most likely cause of this error?
The qtree has not been exported.
In a Fibre Channel configuration, the host's HBA is referred to as the ___________ , and the storage system's HBA is referred to as the __________ .
Which command will show the FCP target(s) on a storage system?
fcp show adapter
Which will enable "symlink_strict_security"?
cifs shares -change <sharename> -symlink_strict_security
What command would create a LUN clone named lun0.clone from the LUN lun0 on the volume vol2?
Ilun clone create /vol/vol2/lun0.clone -b /vol/vol2/lun0 snap_recent
Which 3 FAS deduplication features were added in ONTAP 7.3?
Qtree SnapMirror is supported on the destination for deduplication by enabling on the source, destination, or both systems.
The fingerprint database and the change logs that the deduplication process uses are located outside the volume, in the aggregate.
The deduplication schedule is not tied to a Qtree SnapMirror update, and can be configured just like the deduplication schedule for any volume.
Which three statements apply to an entry in the /etc/exports file regarding exporting directories/qtrees and volumes? (Choose three.)
Each volume must be exported separately.
Host names used in an export must be resolved.
Exports can access multiple paths on the same volume.
When using SnapRestore to restore a single LUN, the LUN must be ___________.
taken offline or unmapped.
What will happen if a soft quota is exceeded?
An SNMP warning message will be generated.
In Data ONTAP the root user is exempt from these two quotas: _______. (Choose two.)
What mechanism allows you to make LUNs available to some initiators and unavailable to others?
If you have a space-reserved, completely full 600G LUN with a volume fractional reservation of 100% and no free space, a snapshot copy of the volume fail.
