Important NetApp NS0-516 Exam Questions

Answer: D

Explanation:

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.

Answer: B

Explanation:

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.

Answer: A

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.

Answer: A, D

Explanation:

The E2800 controller supports Fibre Channel (FC) and iSCSI as base host connectivity options.

FC provides high-speed connectivity for SAN environments.

iSCSI allows for IP-based storage networking, facilitating connectivity over existing Ethernet networks.

Reference: NetApp E2800 Series Hardware Guide, which lists supported host interfaces.

Answer: A

Explanation:

Understand the Requirements: The E2812 system is to be used without expansion shelves, and the customer requires six data volumes.

Consider DDP (Dynamic Disk Pooling): DDP is a recommended configuration for simplifying management and enhancing data protection.

Single DDP Configuration: Using one DDP for all volumes is efficient for the following reasons:

Simplifies the storage configuration.

Ensures balanced use of all drives.

Provides efficient data protection and rebuild performance.

Creation of Volumes: Within the single DDP, create six volumes as required by the customer.

Advantages of One DDP:

Easier management compared to multiple DDPs.

Better performance and protection due to the distributed nature of DDP.
