QUESTION 112

Which three FAS deduplication features exist in ONTAP 8.0 7-Mode?

 

A.

The deduplication fingerprint and change logs were moved to the root volume /etc/dedup directory.

B.

After breaking the deduplication volume destination mirror, the deduplication (a-sis) process continuesuninterrupted.

C.

Qtree SnapMirror is supported on the destination for deduplication by enabling on the source, destination, orboth systems.

D.

The fingerprint database and the change logs that the deduplication process uses are located outside thevolume, in the aggregate.

E.

The deduplication schedule is not tied to a Qtree SnapMirror update, and can be configured just like thededuplication schedule for any volume.

 

Correct Answer: CDE

Explanation:

Data Protection

NetApp also recommends that if deduplication is used on the source volume, then it should also be used onthe destination volume. However, you are not restricted using deduplication on the source volume only.

The deduplication schedule is not tied to the qtree SnapMirror update. In other words, the deduplicationprocess does not automatically start at the completion of the qtree SnapMirror transfer.

The fingerprint database and the change log files that are used in the deduplication process are locatedoutside of the volume in the aggregate and are therefore not captured in Snapshot copies

QUESTION 115

The quota resize command only affects existing /etc/quotas file target entries, not new quota entries.

 

A.

True

B.

False

< font face="Arial"> 

Correct Answer: A

Explanation:

http://backdrift.org/man/netapp/man1/na_quota.1.html

 

quota resize volume

Adjusts currently active quotas in the specified volume to reflect changes in the /etc/quotas file. Forinstance, if you edit an entry in /etc/quotas to increase a user’s quota, quota resize will cause thechange to take effect. The volume name may be omitted if the system has only one volume. quota resizecan be used only when quotas are already on. Because it does not rescan the file system to compute usage,quota resize is faster than turning quotas off and then on again. quota resize will apply all updatedentries in /etc/quotas; however, it will generally ignore newly added entries. A newly added entry will onlytake effect if the corresponding user or group has an active quota as a result of updating a file subject todefault quotas.

 

 

QUESTION 116

NetApp recommends that Fibre Channel switches that have both disk and tape connected to them should have separate zones created for each.

 

A.

True

B.

False

 

Correct Answer: A

Explanation:

http://www.brocade.com/downloads/documents/white_papers/Zoning_Best_Practices_WP-00.pdf

 

Separating the disk and tape devices into separate zones prevents disk RSCNs from impacting tape devices,which tend to be more sensitive to RSCNs.

Best practice is to zone each initiator WWPN to each target WWPN individually.
