NEW QUESTION # 42
A customer has demanding database servers, which require larger I/O queue counts and queue depths. What should be done to increase these parameters for certain hosts?
Answer: D
Explanation:
Increasing the queue depth for the given namespace allows the database servers to handle more outstanding I/O operations simultaneously, directly addressing the requirement for larger I/O queue counts and depths.
NEW QUESTION # 43
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,C
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 # 44
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,D
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.

* NetApp SAN Host Configuration
* NetApp Best Practices for SAN
NEW QUESTION # 45
A customer wants to confirm the compatibility of their server operating system and driver versions before installing a new NetApp ONTAP SAN solution. Which NetApp tool can be used?
Answer: D
Explanation:
The Interoperability Matrix Tool (IMT) allows customers to verify compatibility of server OS versions, drivers, and other components with NetApp ONTAP SAN solutions before installation.
NEW QUESTION # 46
A customer currently operates a legacy iSCSI storage environment that is connected to network switches with several Windows hosts. As part of an upcoming NetApp ONTAP software upgrade, an engineer needs to verify compatibility. Which two NetApp tools would help the engineer assess the environment? (Choose two.)
Answer: A,B
Explanation:
To verify compatibility in an iSCSI storage environment before a NetApp ONTAP software upgrade, the following tools are recommended:
Interoperability Matrix Tool (IMT): This tool helps verify the compatibility of different components, including network switches, hosts, and storage systems, ensuring that the planned upgrade will be supported.
Active IQ OneCollect: This tool collects comprehensive configuration and performance data from the storage environment, which can be used to assess the current setup and identify any compatibility issues before the upgrade.
