Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q20-Q25):

NEW QUESTION # 20
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)

Answer: A,C

Explanation:
To ensure the best performance in an iSCSI SAN implementation:
Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.


NEW QUESTION # 21
A customer asks for help cloning one database LUN from a SnapMlrror destination volume for testing the data with a new application.
What command should the administrator use to clone the LUN?

Answer: D

Explanation:
To clone a LUN from a SnapMirror destination volume for testing purposes, the volume clone create command should be used. This command creates a FlexClone volume from the SnapMirror destination, making the LUN within it accessible for testing without disrupting the original volume.
For more details, refer to:
* NetApp Documentation on Volume Clone Create
* NetApp Community Discussion on LUN Cloning


NEW QUESTION # 22
A storage administrator has a NetApp AFF SAN cluster in a multitenant environment. Another user has requested access to perform only replication within a specific SVM to another cluster.
Which default role would be used in this scenario?

Answer: B

Explanation:
In a multitenant environment where a user needs access only to perform replication within a specific SVM to another cluster, the default role vsadmin-backup is appropriate. This role provides the necessary permissions to manage backup and replication tasks without granting broader administrative rights.


NEW QUESTION # 23
Which functionality enables a host subsystem to have multiple paths to a NetApp ONTAP NVMe namespace?

Answer: D

Explanation:
Asymmetric Namespace Access (ANA) enables a host subsystem to access a NetApp ONTAP NVMe namespace through multiple paths, supporting multipathing for high availability and optimized performance.


NEW QUESTION # 24
When using FCP, what is the minimum number of FC switches needed to redundantly attach three ESXi hosts?

Answer: D

Explanation:
When using Fibre Channel Protocol (FCP), the minimum number of FC switches needed to redundantly attach three ESXi hosts is 2. This setup ensures that each host has multiple paths to the storage, providing high availability and fault tolerance. Each ESXi host should be connected to both switches, allowing for continuous operation even if one switch fails.
