NetApp NS0-516 NetApp Certified Implementation Engineer - SAN Specialist, E-Series Exam Practice Test

Answer : A

CHAP (Challenge Handshake Authentication Protocol): CHAP is a protocol used to authenticate the identity of an initiator or target in iSCSI communications. This ensures that only authorized devices can connect to the storage array over the iSCSI network.

Implementation in E-Series: In the context of E-Series systems, CHAP secrets are configured to provide an additional layer of security by requiring both the initiator and target to authenticate each other using a shared secret before establishing an iSCSI session.

Factory Setting: When ordering the E2800 controller with a 4-port 16Gbps FC or 10Gbps iSCSI SFP+ host interface card (HIC), the host protocol configuration can be predefined based on the customer's specifications. This setting is done at the factory and is ready upon arrival.

SANtricity System Manager Configuration: Administrators can also set or change the host protocol configuration using the SANtricity System Manager. This can be done in the Hardware tab, where the configuration options for the HIC can be modified to suit the desired protocol.

Answer : A

If the management host loses the ability to manage the E-Series system through in-band management but still has access to data volumes, the most likely cause is that the access volume was un-mapped. The access volume is crucial for in-band management as it provides a path for management commands.

In-band management relies on this special volume to communicate management commands between the host and the storage system. If the access volume is un-mapped, the management interface on the host will no longer be able to send these commands, even though data volumes remain accessible.

Answer : C

Based on the exhibit provided and the scenario where a Red Hat Enterprise Linux 7.6 server is configured with Device Mapper Multipathing (dm-mp) for Asymmetric Logical Unit Access (ALUA) and connected to a single volume on the EF280 system, there are 4 active/optimized paths available to the volume.

In ALUA configurations, paths are classified as active/optimized or active/non-optimized. Each controller on the EF280 system will have two active/optimized paths to the volume, leading to a total of four such paths. This setup ensures high availability and optimal performance for data access.

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.

Answer : A, D

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.
