NEW QUESTION # 34
Which two NetApp features enable an administrator to limit the number of paths that a host sees to a LUN?
(Choose two.)
Answer: A,C
Explanation:
Selective LUN Mapping (SLM) and portsets are ONTAP mechanisms specifically used to control the number of paths visible between hosts and mapped LUNs. SLM automatically limits LUN access to paths through the node that owns the LUN and its HA partner, reducing unnecessary paths in larger clusters. A portset provides additional restriction by defining exactly which FCP or iSCSI LIFs an igroup can use to reach its mapped LUNs. NetApp notes that portsets can be combined with SLM when further path restriction is required.
ALUA identifies optimized and non-optimized paths but does not itself reduce the number of visible paths.
An igroup controls which initiators can access a LUN but does not independently restrict target LIF visibility.
Relevant topics include SLM, portsets, igroups, SAN multipathing, and path-count optimization.
NEW QUESTION # 35
Click the Exhibit button.
A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1.
After the failover, what is the expected status of the marked path?
Answer: B
Explanation:
In the scenario where a storage failover is performed on Node 1 in an HA pair, the path marked in the exhibit would become Active/Nonoptimized. After the failover, the LIFs from Node 1 that were active and optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.

NEW QUESTION # 36
An administrator needs to ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time.
Which two configurations enable the administrator to achieve this? (Choose two.)
Answer: C,D
Explanation:
To ensure that Snapshot copies of database files across multiple FCP LUNs are taken at the same point in time, the following configurations can be used:
* Create a consistency group that uses FlexVol volumes: This setup ensures that snapshots of all volumes in the consistency group are taken simultaneously.
* Create each LUN within the same FlexGroup volume: This configuration allows for a unified snapshot across multiple LUNs within the FlexGroup, ensuring data consistency.
For more details, see:
* NetApp Documentation on Consistency Groups
* NetApp FlexGroup Overview
NEW QUESTION # 37
An administrator creates a new SVM for SAN connectivity on their two-node cluster. The customer needs a redundant configuration at the node layer and fabric layer.
How many LIFs, at minimum, should the administrator create for the SVM?
Answer: B
Explanation:
For a redundant two-node FC SAN configuration, NetApp requires two FC LIFs per node when redundancy must exist across both the node and fabric layers. Each node should have connectivity to both independent fabrics, normally through one FC LIF per fabric. With two controller nodes, this results in four SAN LIFs in total. Although ONTAP can technically support a minimum of one FC LIF per node for an SVM, that would provide only two LIFs and would not satisfy the stated requirement for redundant node-layer and fabric-layer connectivity. NetApp ' s FC SVM configuration guidance specifically states that two LIFs per node and two fabrics provide this redundancy. Relevant SAN ONTAP topics include FC SVM configuration, SAN LIF design, dual-fabric architecture, multipathing, node redundancy, and high availability.
NEW QUESTION # 38
An engineer has a 100 GB volume with the space guarantee set to volume and fractional reserve set to 100.
The Snapshot reserve is disabled. The volume contains two 20 GB LUNs, and each LUN has the space guarantee enabled and is 50% full. The engineer creates a Snapshot copy of the volume, and no data is written or modified after the Snapshot copy is taken.
What is the available space in the volume?
Answer: C
Explanation:
The correct available capacity is 20 GB. Both 20 GB LUNs are space-reserved, so ONTAP reserves their full provisioned capacity rather than only the 10 GB currently consumed in each LUN. The two LUN reservations therefore account for 40 GB. Because the volume uses a 100% fractional reserve and a Snapshot copy exists, ONTAP also reserves sufficient overwrite space for 100% turnover of the reserved objects. That represents another 40 GB. Consequently, 80 GB of the 100 GB volume is committed: 40 GB for the two space-reserved LUNs and 40 GB to guarantee their overwrites. This leaves 20 GB available. NetApp describes fractional reserve 100 as reserving 100% of the space necessary for overwrites of reserved objects. Relevant topics include LUN space reservation, fractional reserve, thick provisioning, and Snapshot overwrite guarantees.
