A customer has 3 older F800 series NetApp storage units, currently running ONTAP 6.5. All the
data is in traditional volumes, and there are around 30 qtrees used in all but one volume. In that
final volume, all data lives in the volume but no qtree’s were used. That particular data is simply
mounted on a Unix box for one of his databases.
The data is a mixture of some Windows and some Unix, with a couple of small Oracle databases
running in HP-UK He is in the final stages of agreeing an upgrade purchase to a FAS3000 unit.
Clearly this will run ONTAP 7.x.
He is concerned about how to migrate the data. You have already offered an option to keep his
disk shelves and undertake a ‘risk-free’ head swap, but he is keen to move to larger disks to keep
his footprint down in his datacenter, and also to move to the new world of aggregates and flexible
volumes so he can take advantage of the FlexClone feature, so he wants to undertake a data
migration.
You have made it clear he can keep both systems side-by-side to ensure a smooth move over,
but how would you then propose he migrates the data to ensure the shortest downtime for his
environment?
A - Use VFM to migrate all the data from old to new. Using the DFSroot will make the task 100%
seamless to the users with zero disruption
B - Configure the new system then use Volume SnapMirror to replicate all the data. This will
keep all his mountpoints and everything the same, and make it a very rapid changeover from
traditional’ to ‘flexible’
C - Upgrade his F800 series to ONTAP 7.x, then the existing traditional volumes can be
converted to flexible ones. From that point it will be also seamless to use Volume SnapMirror
to the new FAS3000 unit, with no downtime for his users or databases
D - Configure the new system then use Qtree SnapMirror to replicate all the qtree’s. The Oracle
data that isn’t in the qtree can be replicated with the !qtree option, although you will need to
mount a new mountpoint once cutting over. You might also suggest Multistore to make his
users/application servers believe there are still 3 filers serving their data. Without MultiStore,
there might be some client reconfiguration needed
Answer: D
Your customer would like a robust replication mechanism to enable them to protect against any

Your customer has two data centers, a primary one in London and a smaller one in New York.
They have a small database in New York that they wish to mirror to London. Because of the
location of the site in New York, they anticipate that they will need to be able to copy all of the
data back from London on a regular basis. Which one of the following would you use to calculate
the bandwidth of the link between the sites?
A - The size of the data
B - The change rate of the data
C - The distance between the sites
D - The transmission delay between the sites
Answer: A
In a Metrocluster configuration, takeover of the primary site by the secondary site is
accomplished:
A - Automatically
B - With a single command on each node

D - With a single command on the secondary site
Answer: A
What will be the size of the destination volume alter the initial Volume SnapMirror transfer?
A - The destination volume will be created to match the size of the source volume
B - Because old snapshots will not be transferred, the destination volume will be smaller than the
source volume
C - Because you can keep more snapshots on the destination volume, it will usually be larger
than the source volume
D - The SnapMirror destination volume will be the same size as the source volume
Answer: D
If an asynchronous volume SnapMirror update does not complete before a new update is
scheduled, what happens?
A - The new update is skipped; the following update will be run when it becomes due
B - The running transfer is aborted and the new transfer is started as it will use a newer snapshot
C - SnapMirror increments the requested transfer count on the relationship and will start the new
update atter the end of the running transfer. The counter ensures no updates are lost
D - SnapMirror marks the relationship to run again and will start the new update after the end of
the running transfer
Answer: D
You have a customer who is using SnapManager for Exchange with his FAS3000 storage unit.
Like many other organizations, he has realized that he ought to have a DR plan in place in case
he loses his primary computer room. How could you offer some Net4pp tools to help make this a
simple transition for him, whilst keeping the cost as low as possible?
A - You tell him that VFM is a great replication tool for Windows-based data, and you
recommend he deploys this to replicate his Exchange data
B - You show him that SME already supports SnapMirror natively, and you suggest he take a
second device for his proposed DR site: this can be an asymmetric replication and could
therefore be a smaller-powered machine to save money
C - You point out that Open Systems SnapVault has a client that can handle Exchange, and
recommend that for protecting his data to another system at his DR site
D - You suggest he could combine DR with some archiving and that SME already natively
supports SnapVault to help achieve this in a simple manner
Answer: B
Your customer has a database setup on his Filer which for historical reasons is spread over two
volumes in the same aggregate. They would now like to mirror this to a second filer, but would
like to ensure that they mirror the database at a single point in time. How would you best achieve
this?
A - Ensure that the SnapMirror schedules run at the same time
B - Use aggregate snapshots to ensure the SnapMirrors use a consistent snapshot
C - Move the whole database into a single volume, and use volume SnapMirror
D - SnapMirror both volumes to a single volume on the secondary which will then create a
consistent snapshot
Answer: C

D - This is not possible with SnapLock Compliance; you can only do this with SnapLock
Enterprise
Answer: D
A customer wants to dynamically adjust the SnapMirror transfer rate. They issue a snapmirror
throttle command on the source system. What happens?
A - Nothing. The snapmirror throttle command needs to be issued on the destination storage
system
B - The changed transfer rate will only apply to the current transfer. The next scheduled transfer
will use the maximum transfer rate that is specified in the /etc/snapmirror.conf tile
C - The changed transfer rate will apply to all future transfers until you change it back using
another snapmirror throttle command
D - The current transfer immediately applies the new value

You have a customer who is using SnapManager for Exchange with his FAS3000 storage unit.
Like many other organizations, he has realized that he ought to have a DR plan in place in case
he loses his primary computer room. How could you offer some NetApp tools to help make this a
simple transition for him, whilst keeping the cost as low as possible?
A - You tell him that VFM is a great replication tool for Windows-based data, and you
recommend he deploys this to replicate his Exchange data
B - You show him that SME already supports SnapMirror natively, and you suggest he take a
second device for his proposed DR site: this can be an asymmetric replication and could
therefore be a smaller-powered machine to save money
C - You point out that Open Systems SnapVault has a client that can handle Exchange, and
recommend that for protecting his data to another system at his DR site
D - You suggest he could combine DR with some archiving and that SME already natively
supports SnapVault to help achieve this in a simple manner

Answer: D
You have a customer who has a requirement to have his data in 2 places: in other words1 if he
loses his primary data site he should not lose ANY data.
Specifically, he has an Oracle database to protect, along with some less critical home users
applications: he is comfortable with the user data only being updated nightly, but the database is
of paramount importance to his business.
The database area totals around iTS in size. In his current solution, at peak times, he is creating
50GB Oracle log data every minute. It is hard for him to find out how much data in the database is
changing precisely.
Although it is critical, the database is only online for changes between Sam and 10pm, so there is
some slacktime outside of thatwhen batch jobs and reports run. The impact of those on the data
is notwidely known, butthey can be re-run if there was a problem outside the online day.
The customer tells you his primary and secondary datacenter have a 1 GBit link between them.
What would be the best design to put forward for his requirements?
A - Volume SnapMirror since it can deal with both Oracle and home area’s. Replicate the logs
synchronously, but the database and the home area’s nightly
B - Qtree SnapMirror to give greater granularity of management Replicate the logs
synchronously, but the database and the home area’s nightly
C - Volume SnapMirror to keep things simple for all data: replicate the Oracle database and logs
synchronously and the home areas every night
D - SnapVaultto replicate all data. Replicate the logs synchronously, but the database and the
home area’s nightly
