NEW QUESTION # 49
Click the Exhibit button.
A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1.
After the failover, what is the expected status of the marked path?
Answer: D
Explanation:
In the scenario where a storage failover is performed on Node 1 in an HA pair, the path marked in the exhibit would becomeActive/Nonoptimized. After the failover, the LIFs from Node 1 that were activeand optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.
For more details, see:
* NetApp Documentation on ALUA
NEW QUESTION # 50
A customer opens a support case for performance issues with an FC Oracle database after migrating from a NetApp AFF system to a NetApp All SAN Array (ASA) platform. Further investigation shows that the number of paths exceeds the recommendation for SAN deployment.
What are two ways to address this problem? (Choose two.)
Answer: B,C
Explanation:
When the number of paths exceeds the recommended configuration for SAN deployment, it can cause performance issues. To address this problem, you can:
Use Selective LUN Mapping (SLM): SLM allows you to control which LIFs (Logical Interfaces) are used to access specific LUNs, thus reducing the number of paths and potentially improving performance by aligning with best practice configurations.
Reconfigure the fabric switch zoning: Adjusting the zoning on the fabric switches can help manage and optimize the number of paths, ensuring that there are not too many paths that could lead to inefficient I/O operations and performance degradation.
NEW QUESTION # 51
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: B,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.

* NetApp Community Discussion on iSCSI Performance
NEW QUESTION # 52
To prevent an on-site disaster from occurring, which NetApp protection method should an administrator use to provide a Zero RTO for applications in a SAN environment?
Answer: C
Explanation:
SnapMirror active sync provides zero recovery time objective (RTO) for SAN applications by delivering continuous synchronous replication and automatic failover, ensuring applications remain available without interruption during a site disaster.
NEW QUESTION # 53
An administrator needs to configure Foreign LUN Import on a NetApp HA pair to migrate over FCP LUNs from a third-party array while serving other LUNs. Which two actions are required to complete this task? (Choose two.)
Answer: B,D
Explanation:
To configure Foreign LUN Import (FLI) on a NetApp HA pair to migrate over FCP LUNs from a third-party array while serving other LUNs, the following actions are required:
Create zoning from the third-party array to the cluster: Proper zoning ensures that the NetApp cluster can communicate with the third-party storage array.
Convert a single FC port on each controller to an FC initiator port: This is necessary for the NetApp system to initiate the connection and access the LUNs on the third-party array.
