Question 1

What Is a recommended setting for using the NetApp ONTAP LUN fractional reserve?



Answer : C

The recommended setting for using the NetApp ONTAP LUN fractional reserve is to set the space guarantee to 'volume'. This setting ensures that the required space for overwrites in the volume is reserved, preventing potential write failures when snapshot copies are created. This setup helps in maintaining the performance and reliability of the storage system by ensuring there is always enough space allocated for the LUN.

Question 2

After deleting a LUN, an administrator notices that the space does not show as available. What needs to be done to reclaim the space?



Answer : D

After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.

Question 3

When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)



Answer : A, C

For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:

Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.

Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.

Cisco Documentation on Jumbo Frames


Question 4

A customer has created an SVM for their SAN workloads. They now want to configure the SVM to use NVMe/FC. Which two steps are needed to accomplish this task? (Choose two.)



Answer : A, C

To configure an SVM to use NVMe/FC, the following steps are necessary:

Add the FC protocol: This step involves enabling the Fibre Channel protocol on the SVM, which is required to support NVMe over Fibre Channel.

Create an NVMe/FC LIF: Logical Interfaces (LIFs) must be created to handle NVMe traffic over the Fibre Channel network. These LIFs enable the NVMe namespace access to the host systems.

These steps ensure that the SVM is correctly set up to use NVMe/FC, allowing for efficient and high-performance access to NVMe storage.

Question 5

An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.

What is modified by the convert command?



Answer : D

The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency


Question 6

An administrator installs a new NetApp ONTAP system in a customer's SAN environment. The customer wants to confirm that ALUA correctly changes the path states between Active/Optimized and Active/Nonoptimized.

Which event causes ALUA to change the path states?



Answer : A

ALUA (Asymmetric Logical Unit Access) is a protocol used in SAN environments to manage paths between a host and its storage. It enables the host to recognize and manage paths to the LUNs more efficiently by designating paths as either 'Active/Optimized' or 'Active/Nonoptimized'. A significant event, such as shutting down all FC LIFs on the HA partner node, will trigger ALUA to change the path states. This action effectively causes the storage paths to transition from the HA partner node to the local node, switching the path states from Active/Nonoptimized to Active/Optimized on the paths that remain active.

For more information, you can refer to:

NetApp Community Discussion on ALUA

NetApp Documentation on ALUA


Question 7

A NetApp AFF node in a four-node cluster has a single FC port on one node, which Is used for legacy tape backup. Tape is no longer needed, and the port is disconnected and modified for reuse in the FCP SAN.

Based on this change, which command will verify that the port is usable?



Answer : C

To verify that a modified FC port is usable after it has been repurposed from tape backup to FCP SAN, the command system node hardware unified-connect show should be used. This command checks the status and configuration of the unified connect hardware, ensuring that the port is correctly set up for the new function in the SAN environment.
