6.You have been asked to setup a SnapMirror transfer from an existing volume at the primary site
to a secondary system 320Km (200Miles) away. The volume currently has 7TB data, but it has very
low change and growth rates, so the available link between the sites of 1Mbit/sec is considered
acceptable for the updates. Which one of these methods is not suitable to achieve the initial
(baseline) transfer:
A.Transfer the data across the link, but ensure that transfers only take place during out of office hours
B.Use SnapMirror to transfer the data to a volume on other disk shelves in the primary filer, and then
move the disk shelves to the secondary site by road
C.Use SnapMirror to transfer the data to a volume on disk shelves in another filer at the primary site, and
then move the disk shelves to the secondary site by road
D.Create tapes using SnapMirror and ship these to the remote destination by FedEx. The data can then
be read back onto the secondary system
Correct:A
7.When deciding if Synchronous mirroring is possible between two sites, which of these metrics
would you use to get the most accurate value?
A.Measure the distance between the sites on a map
B.Measure the length of cable/fibre connecting the two sites
C.Measure the transfer rate of asynchronous SnapMirror between the sites
D.Measure the round trip time for packets sent between the sites
Correct:D
8.A customer has a 128Kb link out to a remote office. They would like to speed the baseline
transfer for their volume SnapMirror. Which one of the following approach is the best one?
A.LREP to a portable device (e.g. tape)
B.Increase the TCP window size
C.Increase the number of drives in the root volume
D.SnapMirror to tape
Correct:D
9.Which one of the following requirements would lead you to consider using Qtree SnapMirror for
your replication?
A.The secondary system should have the same snapshot schedule as the primary system
B.You wish to keep a longer retention of snapshots on your secondary to your primary system
C.You wish to have the option to use synchronous SnapMirror for the replication
D.You want snapshots triggered by different applications to get automatically transferred by a default
SnapMirror update
Correct:B
10.You have been asked to analyze the DR requirement for 30TByte of data with a change rate of
about 7% per week. The organization has all their processing and storage capacity at a single
location, though they do have two computer rooms that are physically separate. You have been
asked to base you recommendation on the organizations SLA of: An RPO of 1 hour in the event of
a single computer room outage. An RTO of 1 hour in the event of a single computer room outage.
There must be an archive copy of all data taken each week, to be kept for 7 years. Which solution
would you recommend?
A.Asynchronously mirror from a FAS3020 in one computer room to a second FAS3020 in the other
computer room. Weekly NDMP backup of the data to tape for offsite storage
B.Asynchronously mirror from a FAS3020 in one computer room to a second FAS3020 in the other
computer room which asynchronously mirrors to a third FAS3020 at an offsite location
C.Place storage on a FAS3020 cluster with weekly full NDMP backups and daily incremental NDMP
backups. All tapes will be sent to offsite storage
D.Use SnapVault to backup a FAS3020 in one computer room to a second FAS3020 using ATA disk in the
second computer room. One SnapVault backup each week would be kept as the archive. The latest
SnapVault backup would be used in a DR situation
Correct:A
