What connectivity Is required between NetApp ONTAP clusters in order to configure SnapMirror
active sync across two data centers for FC?
C
Explanation:
To configure SnapMirror active sync across two data centers using FC (Fibre Channel), the required
connectivity between NetApp ONTAP clusters is cluster peering. Cluster peering involves establishing
a trust relationship between the clusters, allowing them to replicate data seamlessly. This setup
ensures that data synchronization and disaster recovery processes are effective and reliable.

What is the minimum number of rack units that are required on each site for a NetApp AFF All San
Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and Cisco N9K-C9336C-FX2
backend switches?
A
Explanation:
For a NetApp AFF All SAN Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and
Cisco N9K-C9336C-FX2 backend switches, the minimum number of rack units required on each site is
16 RU. This includes space for the controllers, disk shelves, and the necessary network switches. This
configuration ensures that all components are properly accommodated and operational within the
specified rack space.

What Is modified when moving a LUN between different HA pairs in the same SVM to prevent loss of
connectivity?
B
Explanation:
When moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity, the
reporting nodes must be modified. The reporting nodes configuration ensures that the initiator paths
are properly updated to reflect the new physical location of the LUN. This prevents disruptions in
connectivity by maintaining the correct pathing information for the host systems accessing the LUN.

NetApp Documentation on LUN Management
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.)
AC
Explanation:
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.

A storage administrator wants to increase security and optimize performance in a recently
implemented SAN deployment.
What should the storage administrator configure to ensure initiator restriction to certain LIFs?
D
Explanation:
To increase security and optimize performance in a SAN deployment, configuring an access list is
essential. Access lists restrict initiator access to specific LIFs, ensuring that only authorized hosts can
connect to the storage system. This helps in enhancing security by preventing unauthorized access
and optimizes performance by controlling and managing the paths used for storage access.

A LUN Is displaying 90% used space in the NetApp ONTAP CLI, but a Windows Server shows only 10%
used space.
What is the first step to take to address this issue?
D
Explanation:
When a LUN shows 90% used space in the NetApp ONTAP CLI but a Windows Server shows only 10%
used space, the discrepancy is often due to how space allocation is handled between the two
systems. Enabling space allocation ensures that the ONTAP system accurately reflects the actual
space usage as reported by the host system, in this case, the Windows Server. This adjustment allows
ONTAP to reclaim and manage space more effectively, aligning the reported usage between the
ONTAP system and the host.

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

After deleting a LUN, an administrator notices that the space does not show as available. What needs
to be done to reclaim the space?
D
Explanation:
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.
For more details, refer to:
NetApp Documentation on Space Reclamation
NetApp Community on Free Space Reclamation
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be
made to enable jumbo frames? (Choose two.)
AC
Explanation:
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.
For additional information, refer to:
NetApp Documentation on NVMe over TCP
Cisco Documentation on Jumbo Frames
On a two-node NetApp AFF ASA cluster, what is the recommended minimum number of paths for a
SAN environment from the client host perspective?
C
Explanation:
In a two-node NetApp AFF ASA cluster, the recommended minimum number of paths for a SAN
environment from the client host perspective is 4. This configuration ensures high availability and
load balancing, which are critical for maintaining performance and resilience in a SAN environment.
Each host should have at least two paths to each controller to achieve this setup.
