Network Appliance NS0-516 Practice Test - Questions Answers

Licensing Requirements: Both the primary and secondary systems must have the same premium features licensed to ensure compatibility and functionality for asynchronous mirroring.

System Discovery: Both systems need to be discovered by an Enterprise Management Window (EMW) or SANtricity Unified Manager to facilitate the setup and management of asynchronous mirroring.

Importance of Matching Features: Ensuring that both systems have the same features licensed avoids issues with mirroring operations that depend on specific functionalities being available on both ends.

Management Tools: Using EMW or SANtricity Unified Manager helps in configuring, monitoring, and managing the mirroring process effectively.

Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the data center power infrastructure can support it without overloading circuits.

Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center's cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.

Ambient Temperatures: The operating environment's temperature should be within the specified range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are controlled is crucial for optimal performance and longevity of the equipment.

Target username and password: These credentials are used by the initiator to authenticate to the target.

Initiator username and password: These credentials are used by the target to authenticate the initiator.

CHAP: Challenge-Handshake Authentication Protocol is used to set up the authentication mechanism.

Modifications in the /etc/iscsi/iscsid.conf file include setting the appropriate values for these parameters.

Reference: NetApp iSCSI Configuration Guide for Linux, which details the configuration of CHAP and other authentication methods.

Understand Pre-Upgrade Health Check:

Purpose: The pre-upgrade health check is designed to ensure the system is in a stable state before proceeding with firmware or software upgrades. This helps to avoid disruptions and data loss.

Volumes on Non-Preferred Path (B):

Issue: If volumes are reported on a non-preferred path, it indicates that there might be a pathing issue or an imbalance in the I/O load.

Impact: Non-preferred paths can lead to performance degradation and increased latency, which might cause issues during the upgrade process.

Resolution: Ensure that all volumes are accessible through their preferred paths before initiating the upgrade.

I/O Being Processed (D):

Issue: Active I/O during the upgrade process can lead to incomplete or failed upgrades.

Impact: Processing I/O during an upgrade can result in data corruption or loss, and may also cause the upgrade to fail.

Resolution: Suspend or stop all I/O operations on the system before starting the upgrade.

Access the Interoperability Matrix Tool (IMT):

Step: Open the NetApp Interoperability Matrix Tool.

Reason: The IMT provides a comprehensive list of supported configurations, including specific versions of drivers and firmware for HBAs.

Navigate to HBA Compatibility:

Step: Search for QLogic HBA compatibility with NetApp E-Series systems.

Reason: To find the exact versions of drivers and firmware that are validated and supported.

Verify the Information:

Step: Cross-reference the information provided by the IMT with the installed hardware.

Reason: Ensuring compatibility to avoid issues related to unsupported 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.

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.

Identify SAS Connector Types: The exhibit shows different types of SAS connectors labeled 1 through 4.

Review E2800 Documentation: According to NetApp E2800 E-Series documentation, the supported SAS connector for expansion and host connectivity is type 1, which is the mini-SAS HD (High Density) connector.

Match the Connector: Verify the appearance and dimensions of the connector in the exhibit. Type 1 matches the mini-SAS HD connector used in the E2800 series.

Confirm Selection: Type 1 (0.74 in / 13.8 mm) is the correct choice for the E2800 family based on the physical characteristics and NetApp specifications.
