Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q23-Q28):

NEW QUESTION # 23
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 becomeActive/Nonoptimized. After the failover, the LIFs from Node 1 that were activeand optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.
For more details, see:
* NetApp Documentation on ALUA


NEW QUESTION # 24
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:
Portsets allow administrators to restrict which LIFs present paths to hosts, and Selective LUN Mapping controls which initiators within an igroup can access specific LUNs, effectively limiting visible paths.


NEW QUESTION # 25
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)

Answer: B,C

Explanation:
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
* Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
* Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I/O operations and performance degradation.
For more details, refer to:
* NetApp SAN Host Configuration
* NetApp Best Practices for SAN


NEW QUESTION # 26
A customer Is setting up a four-node NetApp AFF cluster for use with NVMe/TCP and wants to use automatic host discovery.
Which protocol is used for the discovery of controllers?

Answer: D

Explanation:
For automatic host discovery in a four-node NetApp AFF cluster using NVMe/TCP, the protocol used is mDNS (Multicast DNS). mDNS allows for the discovery of controllers and other networked devices without the need for a centralized DNS server, simplifying the setup process in environments that support NVMe over TCP.
For further information, refer to:
* NetApp Documentation on NVMe/TCP
* NetApp Community on Host Discovery


NEW QUESTION # 27
What should an administrator use to protect an Oracle RAC Automatic Storage Management (ASM) instance to ensure automated restores?

Answer: B

Explanation:
To protect an Oracle RAC Automatic Storage Management (ASM) instance and ensure automated restores, the recommended tool is the NetApp SnapCenter plugin. SnapCenter provides comprehensive backup, restore, and clone capabilities for Oracle databases, including those using ASM. It integrates tightly with Oracle RAC environments and automates the entire data protection process, ensuring that backups are consistent and restores are efficient and reliable.
