NO.1 Regarding clustered Data ONTAP 8.3, what happens to the roles of the on board ports, HBAs,
and NICs?
A. These roles are predefined and must be changed before creating your LIFs.
B. The roles are divided into two categories: Data Management and Node Management.
C. These roles are assignet when LIFs are created.
D. These roles are assigned based on the controller type.
Answer: C

NS0-180学校   NS0-180方法   
Explanation:
In earlier releases of Data ONTAP, default roles were assigned to each Ethernet network port. The
roles included data, cluster, cluster management, intercluster, and node management. In Data
ONTAP 8.3, these roles are assigned when LIFs are created.
Reference: Clustered Data ONTAP 8.3, Network Management Guide, page 7

NO.2 You are adding nodes to an existing cluster.
In this scenario, which three statements are correct? (Choose three.)
A. If you are adding nodes to a two-node switchless cluster, you must have installed and configured
the cluster management and interconnect switches before adding additional nodes.
B. If you are adding a second node to a single-node cluster, the second node must have been
installed, but the cluster network can be configured later.
C. You must add a cluster switch for every two nodes.
D. The switchless cluster functionality is supported only in a single or two-node cluster.
E. If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the
cluster must be healthy.
Answer: A,C,E

Explanation:
C: If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the
cluster must be healthy (indicated by cluster show).
E: If you are adding nodes to a two-node switchless cluster, you must have installed and
configured the cluster management and interconnect switches before adding additional nodes.
Incorrect:
not A: If you are adding a second node to a single-node cluster, the second node must be
installed, and the cluster network must be configured.
Not D: The switchless cluster functionality is supported only in a two-node cluster.

NO.3 Your customer received an HA pair of FAS8040 nodes with two half-populated disk shelves
which they want to add to their cluster. When you arrive to add the nodes to their cluster, the
customer informs you that they have 24 NSE drives that they want to use to fully populate two of the
disk shelves.
What should you do in this scenario?
A. Comply with your customers request, and add the NSE drives before you add the nodes and disk
shelves to their cluster.
B. Change the boot variable bootarg.strorageencryption.support to false.
C. Inform your customer that they cannot mix NSE drives and regular hard disks in a storage system.
D. Move all the NSE disks into one shelf and all the hard disks into the other shelf before you install
the new HA pair.
Answer: C

NS0-180資格難易度   
Explanation:
All disks in the storage system and optional attached disk shelves must have
encryption functionality to be able to use Storage Encryption.
You cannot mix regular non-encrypting disks with self-encrypting disks.
Note: NetApp Storage Encryption (NSE) is NetApp's implementation of full-disk encryption (FDE)
using self-encrypting drives from leading vendors.

NO.4 What network information is required to set up any Cisco switches attached to a clustered Data
ONTAP system? (Choose two.)
A. The appropriate number and type of cables and cable connectors for your switches are required.
B. Host names and IP addresses for each of the controllers and configured switches are required.
C. All management ports configured for e0d or the service port (wrench icon) are required.
D. VLAN tags for each interface are required.
Answer: A,B

NS0-180スクール   NS0-180教育   
Explanation:
C: You need the following network information for all switch configurations: *Two or more IP subnet
addresses for cluster network and management network traffic
*Host names and IP addresses for each of the controllers and all applicable switches
*Management network port assignments for your controller
D: To configure your cluster, you need the appropriate number and type of cables and cable
connectors for your switches. Depending on the type of switch you are initially configuring, you need
to connect to the switch console port with the included console cable.

NO.5 You want to install a new clustered Data ONTAP 8.3 system.
The customer wants to use open ports on interconnect switches from a different system with
clustered Data ONTAP 8.2 because they are running out of space in their rack.
What should be considered in this scenario?
A. A maximum of two clusters per switch pair are qualified and supported, but you should use
trunked ports.
B. Only one cluster per switch pair is qualified and supported.
C. You can only use dedicated ports for the clustered interconnect.
D. You can use all free network ports for the cluster interconnect.
Answer: C

NO.6 What is NetApp's best practice regarding Ethernet flow control?
A. Disable flow control on all 10Gbps ports.
B. Disable flow control on the host, switch, and all node ports.
C. Leave flow control enabled.
D. Disable flow control on the switch ports.
Answer: A
