Question 1

Click the Exhibit button. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-516/page_6_img_1.jpg A customer has a raised floor with a weight limit of 700 lb. per floor tile. The customer’s data cabinet weights 90 lb. and covers a single floor tile. Referring to the exhibit, what is the maximum number of E2824 shelves possible to be installed?

Accepted Answer

C

Explanation: 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.

Question 2

Which NetApp tool provides information on size, weight, acoustic noise, and power of NetApp E- Series systems?

Accepted Answer

A

Explanation: NetApp Hardware Universe (HWU) is the definitive online resource for detailed technical specifications of NetApp hardware. It is specifically designed to provide physical and environmental information required for data center planning. For NetApp E-Series systems, HWU offers comprehensive data on physical dimensions (size), weight, power consumption and requirements, thermal output, and acoustic noise levels. This tool is the primary, officially sanctioned source for architects and administrators to obtain these specific hardware attributes.

Question 3

Click the Exhibit button. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-516/page_7_img_1.jpg Referring to the exhibit, which three statements are true? (Choose three.)

Accepted Answer

A, B, D

Explanation: 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.

Question 4

An administrator is asked to migrate two DE6600 shelves into a newly deployed E5760 environment
that is configured with a stack of two DE460C shelves.
In this scenario, how does the administrator complete this task?

Accepted Answer

C

Explanation: 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.

Question 5

Which two local users of NetApp SANtricity Unified Manager would be used to edit the Certificate Management section? (Choose two.)

Accepted Answer

C, D

Explanation: 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.

Question 6

An administrator is asked to create a Dynamic Disk Pools (DDP) pool from eleven 12 TB disks with the
requirement that there is adequate space available for a reconstruction if a drive in the pool fails.
In this scenario, what should the administrator do to satisfy this requirement?

Accepted Answer

C

Explanation: 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.

Question 7

What are two methods for setting the host protocol configuration on the E2800 controller with a 4- port 16Gbps FC or 10Gbps iSCSI SFP+ host interface card (HIC)? (Choose two.)

Accepted Answer

A, D

Explanation: 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.

Question 8

What does the CHAP secret accomplish for an E-Series system?

Accepted Answer

A

Explanation: 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.

Question 9

When working on a customer’s E-Series system to configure LDAP, you realize that you need to
complete a Certificate Signing Request to receive a certificate.
In this scenario, when entering the information for the CSR, what information do you need from the
controllers themselves? (Choose three.)

Accepted Answer

C, D, E

Explanation: 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.

Question 10

Which two steps are required to enable multifactor authentication on an E-Series system? (Choose two.)

Accepted Answer

C, D

Explanation: 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.

Question 11

A company implemented Automatic Load Balancing (ALB). When the controller workloads are
monitored, it becomes obvious that there is an imbalance and that ALB is not working correctly.
In this scenario, what are two causes of the problem? (Choose two.)

Accepted Answer

C, D

Explanation: NetApp Automatic Load Balancing (ALB) is dependent on the Asymmetric Logical Unit Access (ALUA) protocol. For ALB to function correctly, two key host-side requirements must be met. First, the host's multipathing driver must be ALUA-aware and properly configured to recognize and switch between optimal and non-optimal paths as directed by the ONTAP controller. Second, the initiator group (igroup) on the storage system must be configured with the correct host type (ostype). This setting ensures that ONTAP presents the LUNs with the appropriate ALUA characteristics for the specific host operating system. A failure in either of these components will prevent the host from dynamically balancing the load, resulting in the observed imbalance.

Question 12

To enable one-way authentication in a new iSCSI Linux implementation, which three modifications should you make in the /etc/iscsi/iscsid.conf file on the Linux host? (Choose three.)

Accepted Answer

A, B, C

Explanation: This question asks for the configuration of one-way authentication but requires three answers, which aligns with the configuration for mutual (two-way) CHAP. Assuming the question intended to ask for mutual CHAP, three modifications in /etc/iscsi/iscsid.conf are required. 1. The authentication method must be enabled by setting node.session.auth.authmethod = CHAP. 2. The initiator's credentials (node.session.auth.username, node.session.auth.password) must be set for the target to authenticate the initiator. 3. The target's credentials (node.session.auth.usernamein, node.session.auth.passwordin) must be set for the initiator to authenticate the target. For strictly one-way authentication, only the CHAP method and the initiator username/password would be configured.

Question 13

Which alerting method would be configured using the SANtricity System Manager setup wizard?

Accepted Answer

D

Explanation: The SANtricity System Manager initial setup wizard guides an administrator through the essential first-time configuration steps for an E-Series storage array. One of the dedicated steps in this wizard is "Configure Alerts," which specifically prompts for the configuration of email notifications. This involves entering SMTP server details and recipient email addresses. While other alerting methods like SNMP and Syslog are available, they are configured separately through the main System Manager interface (Settings > Alerts) after the initial setup wizard has been completed.

Question 14

When a drive fails in a Dynamic Disk Pool (DDP) with no free capacity, what happens to the data?

Accepted Answer

B

Explanation: Dynamic Disk Pools (DDPs) in NetApp E-Series systems are designed with integrated spare capacity, known as "preservation capacity." This capacity is reserved specifically for data reconstruction in the event of a drive failure. When a drive fails, the SANtricity controller uses the distributed parity data across the remaining healthy drives to rebuild the data segments from the failed drive. This rebuilt data is then written into the reserved preservation capacity, which is spread across all other drives in the pool. This process is independent of the "free capacity" available for creating new volumes and does not require a dedicated hot spare drive.

Question 15

A customer needs to add an EF280 with FC into its existing Brocade fabric but the FC ports in the
SANtricity System Manager are showing the FC ports as down and the LED on the FC HIC is amber.
Which three tasks does the installer need to complete to solve this problem? (Choose three.)

Accepted Answer

A, B, E

Explanation: The symptoms described—Fibre Channel (FC) ports showing as "down" in SANtricity and an amber HIC LED—indicate a problem at the physical or link layer of the SAN fabric. To resolve this and successfully integrate the EF280 array, the installer must address three key areas: 1. Physical Connectivity: The most fundamental step is to ensure the physical path is complete and correct. This involves verifying that the FC cables are securely plugged into both the EF280 HIC and the Brocade switch ports (B). 2. Link Enablement: Switch ports are often disabled by default for security. The installer must verify the specific ports on the Brocade switch are administratively enabled to allow a link to be established (A). 3. Fabric Access Control: For the server and storage to communicate, the fabric must be configured to permit it. This is achieved through zoning, which requires creating a zone containing the World Wide Port Names (WWPNs) of the EF280 ports and the server's HBA ports (E). These three tasks cover the physical, link, and fabric service layers required for successful integration.
