Topic 1, Volume A

interface on each node in the both the source and destination clusters
B. The cluster interface on the source cluster must be able to communicate with the cluster
interface on the destination cluster
C. The intercluster interface on the source cluster must be able to communicate with the
intercluster interface on the destination cluster

A customer wants to use FlashCache but does not want to lose the information stored in
the FlashCache card when a takeover occurs in a high-availability solution.
What should the customer do to make sure this feature is enabled?
A. Confirm that the aggregates using the FlashCache card are configured appropriately.
B. Set the option to rewarm the FlashCache in both nodes of the HA pair.
C. Verify that the FlashCache card is located in the appropriate slot in the NetApp
controller.
D. Verify that the FlashCache card has been configured only on the node where the feature
is required.
Answer: B
Explanation: The system does not serve data from a Flash Cache or Flash Cache 2
module when a node is shutdown. However, the WAFL external cache preserves the cache
during a graceful shutdown and can serve "warm" data after giveback.
The WAFL external cache can preserve the cache in Flash Cache modules during a
graceful shutdown. It preserves the cache through a process called "cache rewarming,"
Question No : 1 - (Topic 1)

which helps to maintain system performance after a graceful shutdown. For example, you
might shut down a system to add hardware or upgrade software.
Cache rewarming is enabled by default if you have a Flash Cache or Flash Cache 2
module installed. Cache rewarming is available when both nodes in an HA pair are running
Data ONTAP 8.1 or later.

A. 32
B. 16
C. 8
D. 4
Answer: C
A customer enables Storage Efficiency on a volume, intending to use compression only as
data is written. The customer observes that compression is working, but deduplication
processes are still running on a scheduled basis. The customer wants to use compression
without deduplication as the data is written to the volume.
Which action will accomplish this task?
A. Enable post compression on the volume.
B. Create a custom efficiency policy and attach to the SVM.
C. Attach the default efficiency policy to the volume.
D. Attach the inline-only efficiency policy to the volume.
Answer: D
A customer created a volume with the wrong language code.
What should a customer do to correct this problem?
A. Delete the volume and create a volume with the correct language code.
B. Take the volume offline and change the language code.
C. Change the language code on the volume.
D. Change the language code on the parent storage virtual machine.
Answer: A
5

To achieve high-availability within a FAS8080 EX HA pair, which two requirements are
needed? (Choose two.)
A. Connect the NVRAM HA interconnects of the HA pairs.
B. Connect multiple paths from the controllers to the host.
C. Connect the local node to the partner node’s disk shelves.
D. Enable auto-giveback.
Answer: A,B
A customer has a 4-node cluster. Two nodes have FlashCache and the other two nodes
have Flash Pools. The customer is interested in deploying and OLTP application with a
workload that consists of an extreme number of small random writes on four LUNs spread
across four volumes.
What should the customer do to improve performance for the OLTP application?
A. Place all volumes for the application on the nodes with Flash Pools.
B. Deploy all volumes for the application on the two nodes with the FlashCache installed.
C. Split the volumes between the two nodes with FlashCache and two of the nodes with
Flash Pools.
D. Place the volume with the highest read load on the Flash Pool nodes and place the
other volumes on the FlashCache nodes.
Answer: B
Which NetApp management tool configures AutoSupport for nodes in a cluster?
A. OnCommand System Manager
B. ConfigAdvisor
C. OnCommand Performance Manager
D. OnCommand Insight

Answer: A
A company has a vault relationship between ClusterA and ClusterB. After a month of
operations, the SnapVault update fails. The primary and secondary volumes have been
thin provisioned and are reporting available space. There is connectivity between ClusterA
and ClusterB.
What caused the update failure?
A. The primary volume’s aggregate is full.
B. The secondary volume’s aggregate is full.
C. A cluster peering relationship was not refreshed every month.
D. There are 251 Snapshot copies on the destination SnapVault.
Answer: D
A customer requires a solution that will provide site-level and local failover recovery with
support for SMB 3.0.
Which solution accomplishes this requirement?
A. 2-node switchless cluster
B. Fabric MetroCluster
C. Stretch MetroCluster
D. 8-node cluster
Answer: B
Which command would you use to disable an account in clustered Data ONTAP?
7

A. security login lock
B. security login policy
C. security login domain-tunnel
D. security login modify
Answer: A
Explanation: Run the following command to disable the diag account for clustered Data
ONTAP:security login lock diag

A customer wants to use a UTA2 PCIe card in a new FAS8000 system.
Which three steps must be completed before the customer is able to use the ports for Fc
access to an FCP switch? (Choose three.)
A. Use the system hardware unified-connect modify command to change the personality
from initiator to target.
B. Verify the WWPN of the UTA2 so that these can be used in the igroup to map the LUNs
for host access.
C. Verify that the correct SFP+ is installed for FC.
D. Verify the card’s hardware configuration by running the system hardware unified-
connect show command.
E. Verify that Data ONTAP iSCSI, GIFS, and NFS are licensed on the system.

A customer creates four broadcast domains with the following ports included for node cl-01:
bcast1 – e0c
bcast2 – e0d
bcast3 – e0e
bcast4 – e0f
A customer creates a LIF and specifies a home port of cl-01:e0f. After LIF creation, the
administrator modifies the home port to use cl-01:e0c.
Which broadcast domain is the LIF using now?
A. bcast4
B. bcast2
C. bcast1
D. bcast3
Answer: C
A NetApp cluster is connected to two network switches for resiliency. One of the network
switches loses power. Most LIFs on the cluster automatically recover from the switch failure
to and are reachable through the network. One LIF used for CIFS access is not reachable
through the network until power is restored to the failed switch.
Which two areas should be investigated to determine the problem? (Choose two.)
A. The protocols allowed on the LIFs.
B. The LIFs failover-group configuration.
C. The LIFs home port.
D. The broadcast domain’s member ports.
Answer: B,D

A customer has two SVMs joined to separate Active Directory domains. SVM1 is joined to
domain AD1 and SVM2 is joined to domain AD2. The administrator enables Active
Directory access to allow certain domain users access to the cluster using their Active
Directory credentials. After enabling, some users report the inability to log into the cluster
using their Active Directory credentials.
What are three reasons this happened? (Choose three.)
A. The user account belongs to the domain that is not used for cluster access
authentication.
B. The cluster time is off by two minutes from the Active Directory time server.
C. The authentication tunnel was deleted and access sessions were disconnected.
D. The Active Directory user account is not added to the cluster as a user.
E. The user is not a member of an Active Directory group that is allowed access to the
cluster.
Answer: A,D,E
What will the storage aggregate create –aggregate aggr0_rg0 –diskcount 40 –maxraidsize
