Pass the Netapp NCIE SAN E-Series NS0-516 Questions and answers with ValidTests

To enable multifactor authentication (MFA) on an E-Series system, follow these steps:

Map roles (C):Role mapping is necessary to define the permissions and access levels for different users when MFA is enabled. This ensures that only authorized users can access specific functions and data on the system.

Configure LDAP (D):LDAP configuration is required for integrating with directory services to manage user authentication and access control. LDAP settings need to be correctly configured to support MFA, allowing the system to authenticate users against an external directory service.

Total weight capacity per tile: 700 lb.

Data cabinet weight: 90 lb.

Available weight for shelves: 700 lb. - 90 lb. = 610 lb.

Weight of an E2824 shelf (maximum): 60.5 lb.

Number of shelves: 610 lb. / 60.5 lb. ≈ 10 shelves

However, considering the safety margin and not exceeding the weight limit, we take 6 shelves as a practical maximum.

Understand ALB Requirements:Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.

Check Host Multipath Driver:

Verify if the host multipath driver installed supports ALB.

Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.

Review Host Type Compatibility:

Ensure the host types used in the configuration support ALB.

Certain host types might not be compatible, resulting in ALB malfunction.

Potential Causes:

Host Multipath Driver (C):If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.

Host Type (D):Incompatible host types can lead to issues with ALB implementation, causing imbalances.

Steps for Resolution:

Update or replace the host multipath driver with a version that supports ALB.

Reconfigure or update the host types to ensure compatibility with ALB.

To create a Dynamic Disk Pool (DDP), the minimum number of drives required is 12. This minimum requirement ensures that there is enough capacity and redundancy to maintain the performance and data protection characteristics that DDPs provide.

Dynamic Disk Pools are designed to optimize data distribution and rebuild times. By using 12 drives as a baseline, the system can efficiently distribute data and parity information across the drives, improving fault tolerance and rebuild performance compared to traditional RAID configurations.

Review the Available Capacity:According to the exhibit, the volume group has a total of 17820.00 GiB capacity, out of which 5532.00 GiB is the current free capacity. However, it is split into two free capacity areas of 15120.00 GiB and 2412.00 GiB.

Identify the Challenge:The requested volume of 5532 GiB cannot be created directly from the current free capacity because it is not contiguous; it's split into two separate areas.

Consolidate the Capacity:To create the volume, the administrator needs to consolidate the free capacity. This involves merging the non-contiguous free spaces to form a contiguous space large enough for the 5532 GiB volume.

Procedure for Consolidation:

Access the volume group management settings.

Select the option to consolidate free capacity areas.

Follow the prompts to merge the two free capacity areas into a single contiguous space.

Create the Volume:Once the free capacity is consolidated, proceed to create the 5532 GiB volume from the newly formed contiguous free space.

Explanation:

Data integrity issues can often be prevented by ensuring that mechanisms for data assurance and media scanning are activated.

Data Assurance (DA) is a feature that verifies the integrity of the data as it is read from or written to the storage system, detecting and correcting errors.

Media scan is a background process that checks the entire disk surface for errors and corrects any found before they cause data integrity issues.

Together, these features ensure ongoing data integrity by preemptively identifying and fixing potential issues.

The pool is expanded by 800 GB

Explanation: When a larger drive (1.6 TB) is added to a Dynamic Disk Pool (DDP) that consists of smaller drives (800 GB), the pool expands only by the size of the existing drives in the pool. Hence, in this scenario, the pool would be expanded by 800 GB.

To find the Worldwide Port Names (WWPNs) for a Windows host, you can check the following locations:

FC Switch (A):The WWPNs are available in the management interface of the Fibre Channel switch to which the host is connected. By accessing the switch's management tools, you can list all connected devices and their WWPNs.

HBA Vendor’s Utility (D):Host Bus Adapter (HBA) vendors typically provide utilities or management software that allows you to view the properties of the HBAs installed in the system. These utilities will display the WWPNs of the HBA ports.

Explanation:

To see all the host selections for NetApp E-Series storage systems, you need to choose the appropriate category from the search list in the NetApp Interoperability Matrix Tool.

The exhibit shows a list of categories and solutions. Among these, the "E-Series SAN Host" category specifically refers to configurations and compatibility for hosts that connect to E-Series storage systems.

Selecting this option will provide a comprehensive list of supported host configurations for E-Series systems.

OM4

Explanation: OM4 fiber optic cables are recommended for 32 Gb FC connections up to 100 meters due to their high bandwidth capabilities and lower attenuation, ensuring optimal performance for such high-speed connections.
