Netapp NetApp Certified Implementation Engineer - SAN Specialist - E-Series NS0-516 Exam Dumps: Updated Questions & Answers (October 2025)

Purpose: To display the average latency time on a per LUN basis.

Command:lun stats -i 5

Usage: Provides performance statistics, including latency, for each LUN at specified intervals (every 5 seconds in this case).

References: NetApp Data ONTAP Command Reference Guide.

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.

Enable AutoSupport:

Step:Configure AutoSupport on the EF570 system with the option to store data locally.

Reason:This allows the system to generate and save support data without needing immediate Internet access.

Set Interval for Data Collection:

Step:Set AutoSupport to run at regular intervals.

Reason:Regular intervals ensure that up-to-date support data is available for NetApp.

Manual Data Transfer:

Step:Periodically transfer the collected support data from the local storage to a server with Internet access.

Reason:This server can then send the support data to NetApp.

Send Data to NetApp:

Step:Use the server with Internet access to forward the collected support data to NetApp's support systems.

Reason:This ensures NetApp receives the necessary support data for ongoing maintenance and troubleshooting.

Understanding Load Distribution: In a duplex E-Series system, load distribution between controllers can be manually set up to optimize performance based on specific workload characteristics.

Automatic Load Balancing: This feature automatically redistributes workloads between controllers to balance the load. However, in a highly tuned environment with manually configured load distribution, this automatic feature can disrupt the optimized settings.

Disabling Automatic Load Balancing: To maintain the manual load distribution over time, the Automatic Load Balancing feature should be disabled. This ensures that the workload remains distributed according to the specific manual configuration without interference from automatic adjustments.

Verify Switch Port Status:

Step:Check the status of the FC ports on the Brocade switch.

Reason:The ports need to be enabled for communication.

Exhibit Analysis: The exhibit shows the rear view of an E-Series controller with various ports.

SAS expansion ports: 2 ports (EXP1 and EXP2).

SAS host ports: 6 ports.

FC/iSCSI ports: 2 ports (these ports can be configured as either FC or iSCSI).

References: NetApp E-Series hardware manual and port configuration guides.

Explanation: To support multiple mirroring relationships, each with different recovery point objectives (RPOs), the administrator should create multiple mirror pairs. Each pair can be configured with its own schedule and RPO, allowing for tailored data protection strategies that meet specific needs.

Reference: NetApp SANtricity Storage Manager Configuration and Provisioning Guide.

In a Dynamic Disk Pool (DDP), the system is designed to handle drive failures efficiently without impacting data availability. When a drive fails within a DDP and there is no free capacity, the data from the failed drive is rebuilt using preservation capacity within the DDP.

Dynamic Disk Pools use distributed sparing, which allows the spare capacity to be spread across all the drives in the pool rather than relying on dedicated hot spare drives. This distribution ensures that the rebuild process starts immediately and can be completed faster than traditional RAID systems because the workload is shared across more drives.

The preservation capacity is essentially reserved space within the DDP that can be utilized in the event of a drive failure to rebuild the data. This approach helps in maintaining redundancy and protecting data integrity even when a drive fails.

Cabling method: It is important to distribute the connections for redundancy and balanced performance.

EXP1 and EXP2 ports: By dividing these ports between the A-side and B-side IOM-12 modules, the system ensures balanced load and failover capabilities.

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.
