NEW QUESTION # 106
Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
Answer: C,D
NEW QUESTION # 107
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,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.

NEW QUESTION # 108
A storage engineer in SAN environment needs to Identify FC ports using the company-wide naming policy.
Which command will accomplish this task?
Answer: B
Explanation:
The vserver fcp wwpn-alias set command is used to set or modify the World Wide Port Name (WWPN) aliases for Fibre Channel (FC) ports in a NetApp ONTAP environment. This command allows you to apply a company-wide naming policy to FC ports, ensuring consistent and easily identifiable naming conventions across your storage infrastructure.
For further details, you can refer to:
* NetApp Documentation on FC Management
* NetApp Community Discussion on WWPN Aliases
NEW QUESTION # 109
What does an Active/Optimized path mean in a FAS configuration?
Answer: D
Explanation:
In a traditional FAS SAN configuration, ONTAP uses ALUA to distinguish optimized paths from non- optimized paths. Active/Optimized paths are serviced by the controller associated with the aggregate and LUN being accessed. These paths provide the preferred I/O route because data does not need to be forwarded through another controller. Paths through the HA partner remain available but are normally Active/Non- Optimized and are used when optimized paths become unavailable. NetApp host configuration guidance explicitly describes AFF and FAS systems as having higher-priority Active/Optimized paths serviced by the controller where the aggregate resides and lower-priority non-optimized paths served through another controller. Round-robin is a host multipathing policy and does not define ALUA path state. Relevant topics include ALUA, Active/Optimized paths, Active/Non-Optimized paths, FAS multipathing, and HA architecture.
NEW QUESTION # 110
A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.
Which action should be taken?
Answer: C
Explanation:
To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:
ping -M do -s 8972 < target_IP >
In this command:
* -M do ensures the packets are not fragmented.
* -s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header).
By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.
For more details, you can check:
* NetApp Documentation - iSCSI Configuration and Best Practices ( NetApp ) ( NetApp ).
