NS0-516 Practice Questions

Based on a strict calculation using the provided figures, none of the answers are correct. The available weight capacity is the floor limit (700 lb) minus the cabinet weight (90 lb), which equals 610 lb. With each fully populated E2824 shelf weighing 120 lb, the maximum number of shelves is 610 / 120 = 5.08. As only whole shelves can be installed, the true maximum is 5.

However, since 5 is not an option, the question is flawed. The intended answer is likely 6, which would be correct if the floor weight limit was 810 lb instead of 700 lb, as (810 lb - 90 lb) / 120 lb = 6. This suggests a typographical error in the question's premise.

A. 22: The total weight of (22 120 lb) + 90 lb = 2730 lb would grossly exceed the specified 700 lb floor limit.

B. 10: The total weight of (10 120 lb) + 90 lb = 1290 lb would significantly exceed the specified 700 lb floor limit.

D. 14: This result is obtained by incorrectly using the empty shelf weight (43 lb). Capacity planning must always use the fully populated weight (120 lb) for safety and operational standards.

1. NetApp E2800 and E5700 Hardware Installation and Maintenance Guide: The physical specifications for the E2824 shelf are listed

confirming the weight for a fully populated shelf is 120 lb (54.4 kg). This document validates the weight value used in the calculation. (Refer to Chapter 1: "System Overview"

Section: "Physical specifications").

2. NetApp E-Series Site Requirements and Cabling Guide: This guide outlines the environmental and physical planning requirements for E-Series systems. It emphasizes that the customer is responsible for ensuring the floor can support the total weight of the cabinet and all installed components

confirming the correct calculation methodology. (Refer to Chapter 2: "Site requirements"

Section: "Weight and floor loading specifications").

The exhibit displays the rear of a NetApp E2800 series controller.

(A) Each controller has two dedicated 12Gb SAS expansion ports (Mini-SAS HD, SFF-8644) for connecting to additional disk shelves (DS224C or DE460C). These are clearly visible and labeled with a downward arrow symbol.

(D) The controller is populated with a Host Interface Card (HIC) that has two SFP+ ports. These ports are universal and can be configured for either 16Gb Fibre Channel (FC) or 10GbE iSCSI host connectivity.

(B) While the controller in the exhibit has two onboard 12Gb SAS host ports, the E2800 platform also supports an optional 4-port 12Gb SAS HIC. A configuration with this HIC would result in six SAS host ports per controller (2 onboard + 4 on the HIC). Therefore, this is a true statement about the platform's capabilities.

C. The iSCSI-capable ports shown in the exhibit's HIC are SFP+ optical ports, not Base-T (RJ-45) ports.

E. The controller has two onboard SAS host ports. A total of four SAS host ports would require a 2-port SAS HIC, which is not what is described in this option.

According to NetApp E-Series hardware installation guidelines, when creating a mixed-shelf stack, specific shelf models must be placed in a prescribed order. For an E5760 system, if you are mixing DE6600 drive shelves with other supported drive shelf models (such as the DE460C), the DE6600 shelves must always be cabled at the end of the SAS stack, furthest from the controller shelf. This ensures proper SAS connectivity and system stability across the different shelf types.

A. Cable the DE6600s at the beginning of the stack

This is incorrect. Cabling the DE6600 shelves at the beginning of a mixed-shelf stack violates the documented hardware configuration rules for E-Series systems.

B. Cable the DE6600s into a separate stack

This is incorrect. While technically possible if the controller has available SAS ports, it is not the standard procedure for expanding an existing stack and is not the required method for mixing these shelf types.

D. Cable the DE6600s between the DE460C shelves

This is incorrect. Placing the DE6600 shelves in the middle of the stack also violates the rule that they must be located at the end of a mixed-shelf configuration.

1. NetApp E5700 Series Installation and Setup Instructions for 2U Controller Shelves. In the section "Rules for connecting drive shelves

" the documentation states: "If you are mixing DE6600 drive shelves with other supported drive shelves

you must place the DE6600 drive shelves at the end of the drive channel (stack)." (This rule is consistently found in the installation guides for E-Series controllers that support these shelves).

2. NetApp Hardware Universe (hwu.netapp.com). The configuration rules for the E5760 controller specify the supported expansion shelves and the required cabling order for mixed-shelf stacks

confirming that certain high-density or newer generation shelves must be placed at the end of the SAS chain.

In NetApp SANtricity Unified Manager, user access is governed by Role-Based Access Control (RBAC). The admin role is a superuser with full permissions across the entire system, which inherently includes the ability to manage security settings like certificates. The security role is specifically designated for managing all security-related configurations. This includes tasks such as managing user roles, access control, audit logs, and certificate management. Therefore, both the admin and security local users have the necessary privileges to edit the Certificate Management section.

A. storage: The storage role is restricted to managing storage objects, such as creating volumes, pools, and host mappings. It does not have permissions for security administration.

B. support: The support role is intended for maintenance and troubleshooting tasks, such as collecting support bundles and viewing system status. It lacks privileges to modify security configurations.

Administrator (admin): "Has all the capabilities of the other roles." This confirms it can perform security tasks.

Security Admin (security): "Manages security settings for the storage array

Dynamic Disk Pools (DDP) are designed to improve data protection and simplify management by eliminating the need for dedicated hot spare drives. When a DDP is created, spare capacity is automatically reserved and distributed in small segments across all drives within the pool. If a drive fails, the data is reconstructed into this reserved space on the remaining healthy drives. The administrator's only action is to create the pool; the system's inherent design automatically allocates the necessary reconstruction capacity, satisfying the requirement without further manual intervention.

A. Create the disk pool, and then edit the pool to reserve 12 TB of space

This is incorrect. Spare capacity reservation is an integral part of the DDP creation process, not a separate, post-creation editing task.

B. Create the disk pool, and then add another 12 TB drive to the pool

This is unnecessary. A DDP with eleven drives already has sufficient built-in, automatically reserved capacity to handle at least one drive failure.

D. Create the disk pool, and then create a hot spare on another 12 TB disk

This describes a traditional RAID group configuration. DDPs use distributed spare capacity and do not use or require dedicated hot spare disks.

1. NetApp Technical Report TR-4090: Dynamic Disk Pools on NetApp E-Series.

Section: "Dynamic Disk Pools Overview

" Page 5.

Quote: "DDPs eliminate the need for dedicated hot-spare drives by distributing spare capacity throughout the pool of drives. When a DDP is created

a certain amount of capacity is reserved for reconstruction in the event of a drive failure." This confirms that spare capacity is an automatic

built-in feature of DDP creation.

2. NetApp E-Series SANtricity 11.70 System Manager Online Help.

Section: "Storage & copy services > Dynamic disk pools."

Content: The documentation describes how DDPs work

stating

"Spare capacity is distributed across all of the drives in a disk pool... If a drive fails

data is reconstructed into the spare capacity on the remaining drives in the pool." This highlights the integrated nature of the spare capacity

contrasting with the incorrect options.

3. NetApp E-Series and EF-Series SANtricity System Manager Guide.

Section: "Create volume groups or disk pools."

Content: The guide details the steps for creating a disk pool. It shows that during creation

the system automatically calculates and reserves preservation capacity based on the number of drives. There is no subsequent step to "edit" the pool to add this capacity or to assign a hot spare.

The 4-port 16Gbps FC / 10Gbps iSCSI SFP+ Host Interface Card (HIC) for the E2800 is a unified, multi-protocol card. Its initial protocol is configured at the factory according to the customer's purchase order. If requirements change after deployment, the protocol can be modified by an administrator. This is accomplished within SANtricity System Manager by navigating to the Hardware page, selecting the controller containing the HIC, and using the option to configure the host ports to switch between Fibre Channel and iSCSI protocols.

B. The specified HIC uses SFP+ transceivers, not QSFP. The protocol is a software setting, not determined by the physical transceiver type.

C. Feature Packs in SANtricity are used to enable licensed software functionalities (like Snapshots or Volume Copy), not to configure the base protocol of a hardware component.

1. NetApp E2800 and E5700 Systems Hardware and Maintenance Guide

Page 51

Table: "Host interface cards (HICs)".

The description for the "16 Gb FC/10 Gb iSCSI 4-port HIC" states: "The protocol for this HIC is set at the factory. You can change the protocol using SANtricity System Manager." This directly supports answers A and D.

2. NetApp SANtricity System Manager 11.70 Online Help

Section: "Configure host ports".

This section provides the procedure for changing the protocol. It states

"You can change the protocol used by the host ports on a host interface card (HIC) that supports multiple protocols... From the Hardware page

select the controller with the host ports you want to configure." This confirms that the configuration is done in the Hardware tab of SANtricity System Manager

supporting answer D.

The Challenge-Handshake Authentication Protocol (CHAP) is an authentication scheme used by iSCSI initiators and targets to verify each other's identity. On a NetApp E-Series system, configuring a CHAP secret enables authentication for iSCSI sessions. This ensures that only authorized hosts (initiators) with the correct secret can establish a connection and access the storage resources (targets) presented over the iSCSI protocol. E-Series supports both one-way CHAP, where the target authenticates the initiator, and mutual CHAP, where the initiator also authenticates the target.

B. Ethernet management authentication: Management access to the E-Series controller (e.g., SANtricity System Manager) is secured using role-based access control (RBAC) with local user accounts or directory services like LDAP, not CHAP.

C. FC authentication: Fibre Channel (FC) SANs primarily use World Wide Name (WWN) zoning and LUN masking for access control and security, not the CHAP protocol.

D. SAS authentication: Serial Attached SCSI (SAS) is a point-to-point protocol where security is typically managed at the physical layer or through zoning in a SAS fabric, not with CHAP.

1. NetApp E-Series SANtricity 11.70 iSCSI Configuration Guide: In the section "Authentication

" it states

"You can use the Challenge-Handshake Authentication Protocol (CHAP) to authenticate the connection between a host and a target. The storage array supports one-way CHAP and mutual CHAP." (Page 11)

2. NetApp E-Series SANtricity System Manager Online Help: The help topic for configuring iSCSI settings details the CHAP authentication procedure. It describes setting a CHAP secret to "authenticate iSCSI initiators that attempt to connect to this storage system." This confirms its exclusive use for iSCSI. (Accessed via SANtricity System Manager GUI: Settings -> iSCSI -> Modify CHAP settings)

When generating a Certificate Signing Request (CSR) within NetApp SANtricity System Manager for an E-Series system, you must provide information to build the certificate's identity. This includes the controller's Common Name (CN), which is typically its Fully Qualified Domain Name (FQDN). It also requires geographical information, such as the Country, State/Province, and Locality. Finally, to ensure the certificate is valid for all access methods, you must specify Subject Alternative Names (SANs), which can include other DNS names or IP addresses for the controllers. These fields are standard components of a CSR used by a Certificate Authority to issue a valid certificate for secure communications like LDAP.

A. the controller’s alternate IP addresses: This is too specific. The correct field is "alternate names," which is a broader category that can include IP addresses as well as other hostnames.

B. the controller’s serial number: The hardware serial number is a physical identifier and is not a standard field required when generating a CSR for a web management interface.

1. NetApp E-Series SANtricity 11.70 System Manager Guide

Section: "Manage certificates". The guide details the "Generate Certificate Signing Request" dialog box

which explicitly requires the following fields:

Common Name

Organization

Enabling multifactor authentication (MFA) on a NetApp E-Series system is accomplished by integrating with a centralized directory service that handles the authentication, which can include an MFA provider. The first required step is to configure the connection to the directory server using LDAP (Lightweight Directory Access Protocol). Once the E-Series system can communicate with the directory service for user authentication, the second required step is to map the user groups from that directory to the specific access roles within SANtricity System Manager. This ensures that authenticated users receive the appropriate permissions on the storage system.

A. Test SSO login: This is a verification action performed after the configuration is complete, not a required step to enable the functionality.

B. Configure In-Band Management: Network management access is required, but it can be configured either in-band or out-of-band. Specifying in-band management is not a mandatory prerequisite for MFA.

1. NetApp E-Series SANtricity System Manager Documentation

"Configure a directory server": This official documentation outlines the procedure for setting up external authentication. It states

"You can use a directory server to authenticate storage array users. To do so

you must configure the directory server settings and then map the directory user groups to SANtricity System Manager's predefined roles." This directly supports configuring LDAP (D) and mapping roles (C).
