Question: 1
You
want to create a data volume on aggr0 and you receive a message with the
following warning:
''Warning:
You are about to create a volume on a root aggregate. This may cause severe
performance or stability problems and therefore is not recommended. Do you want
to proceed?''
What
is the reason for this severe performance or stability problem?
A.
Controller failover and storage failover are separate processes that must occur
in parallel, otherwise problems will arise.
B.
The performance load generated by the data volume can be very strong, so it
should not be shared with vol0 on aggr0, requiring a separate aggregate for it.
C.
The performance load generated by the vol0 cannot be shared with any other
volume on aggr0, requiring a dedicated aggregate for it.
D.
Controller failover and storage failover are separate processes that must occur
at different times, otherwise problems will arise.
Answer:
B
Explanation:
One
possibly cause is Disk I/O contention on the data volume.
The
root volume in Cluster-Mode is used to store and update various tables of the
replicated database. Crucial information regarding the locations of LIFs,
volumes, aggregates, and different jobs required to run in the cluster are
stored in these tables. If a root aggregate has very busy data volumes, the
disks in the aggregate will experience higher latency. When a node is unable to
update its copy of the replicated database fast enough, it will consider itself
unhealthy and stop serving all the data until it can catch up. This is
extremely disruptive and affects all the volumes on the node, even if the cause
is related to the data volumes stored on the root aggregate only.

is a warning displayed when attempting to create one or more data volumes in
the root aggregate in Data ONTAP Cluster-Mode?
Question: 2
You
have completed a clustered Data ONTAP installation for a new customer. You are
now ready to hand off the system to the customer.
Which
three actions should you take at this stage in the installation process?
(Choose three.)
A.
Show the customer how to open a case with NetApp Support.
B.
Demonstrate System Manager and its functionality.
C.
Tell the customer to call their sales representative if there are further
questions.
D.
Tell the customer you are finished and then leave the site.
E.
Show the customer how to set up a support account.
Answer:
A,B,E
Question: 3
What
happens to the NTP configuration in clustered Data ONTAP 8.3 when a node joins
a cluster?
A.
A node that joins a cluster has a separate NTP service.
B.
A node that joins a cluster automatically adopts the NTP configuration of the
cluster.
C.
A node that joins a cluster must be manually configured in the NTP.
D.
A node that joins a cluster must reboot before running the NTP service.
Answer:
B
Explanation:
A
node that joins a cluster automatically adopts the NTP configuration of the
cluster.

Question: 4
You
are assigned to install five DS2246 with twenty-four 400 GB SSDs per shelf to a
single node system.
According
the NetApp, which statement is correct?
A.
You cannot install five SSD shelves to one System.
B.
You need at least two stacks.
C.
You need at least three stacks.
D.
You can put all shelves in one stack.
Answer:
D
Explanation:
Up
to 10 shelves are supported per stack for the DS2246, so we one stack is enough
as we only have five shelves (DS2246s).

Question: 5
Which
three types of interface groups are supported on NetApp storage systems?
(Choose three.)
A.
single mode
B.
HA interconnect
C.
IPspaces
D.
static multimode
E.
dynamic multimode
Answer:
A,D,E
Explanation:
You
can create three different types of interface groups on your storage system:
single-mode, static multimode, and dynamic multimode interface groups.

Question: 6
You
have just configured the customer's first SVM with a LIF IP 10.0.0.10/24. The
customer's DNS IP address is 172.16.0.250 and you are unable to ping it from
the NetApp storage system, but you are able to ping the gateway and everything
else works.
In
this scenario what is the problem?
A.
You need to have the DNS server on the same subnet as the LIF IP address.
B.
You need to add a static gateway to the LIFs routing group.
C.
You need to have the customer check the cable.
D.
You need to add an IPspace and domain broadcast to the port.
Answer:
D
Explanation:
A
broadcast domain resides in an IPspace, and it contains a group of network
ports, potentially from many nodes in the cluster, that belong to the same
layer 2 network. The ports in the group are used in an SVM for data traffic.
