NEW QUESTION # 52
What Is modified when moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity?
Answer: 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.

NEW QUESTION # 53
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,B
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 # 54
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?
Answer: 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.
NEW QUESTION # 55
A customer has a two-node NetApp ONTAP cluster that Is hosting FC LUNs for 64 SAN hosts.
An administrator is tasked to add 40 more hosts to the environment. What two actions would the administrator need to take to avoid potential performance problems with the environment?
(Choose two.)
Answer: B,C
Explanation:
When adding 40 more hosts to a two-node NetApp ONTAP cluster that is already hosting 64 SAN hosts, the following actions are necessary to avoid potential performance problems:
Configure additional FC target ports: Increasing the number of Fibre Channel (FC) target ports on the storage nodes will help distribute the I/O load more evenly, reducing the risk of bottlenecks.
Configure additional SAN LIFs: Adding more SAN Logical Interfaces (LIFs) will ensure that the increased number of hosts can connect efficiently, improving load balancing and path management.
These actions help maintain optimal performance and prevent congestion in the SAN environment.
NEW QUESTION # 56
An administrator upgraded their NetApp ONTAP software from release 9.10.1 to 9.13.1 on a NetApp All SAN Array (ASA) cluster and is creating a new iSCSI SVM. Which automatic feature can be used with iSCSI?
Answer: B
Explanation:
In NetApp ONTAP 9.13.1, one of the automatic features that can be used with iSCSI is LIF failover. This feature ensures that in the event of a network failure or a node issue, the Logical Interface (LIF) will automatically fail over to another available port, maintaining connectivity and minimizing disruption to iSCSI traffic.
