At ValidExamDumps, we consistently monitor updates to the NetApp NS0-516 exam questions by NetApp. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the NetApp Certified Implementation Engineer - SAN Specialist, E-Series exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by NetApp in their NetApp NS0-516 exam. These outdated questions lead to customers failing their NetApp Certified Implementation Engineer - SAN Specialist, E-Series exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the NetApp NS0-516 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A customer wants to manage an E-Series system over a secure connection between the system and a server. During implementation, you are asked to fulfill this installation requirement.
In this scenario, which three actions are required to complete this task? (Choose three.)
Secure Connection Requirement: To manage the E-Series system over a secure connection, certain steps need to be taken to ensure encrypted communications.
Disabling Legacy Management Interface: This step ensures that only secure management interfaces are used, preventing the use of less secure legacy protocols.
Certificate Signing Request (CSR): Completing the CSR on the system is necessary to generate a public/private key pair. This CSR can then be submitted to a certificate authority (CA) to obtain a signed certificate.
Importing CA Signed Certificates: Once the CA has signed the certificate, it must be imported into the E-Series system. This signed certificate ensures that the communication between the server and the system is encrypted and trusted.

A customer intends to use an E2812 system without expansion shelves. The specification for their Windows host requires that six E-Series data volumes be used.
In this scenario, how should the system be configured?
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.
Which iSCSI setting would you change from its default value to increase the throughput of an iSCSI host port on a NetApp E-Series system?
To increase the throughput of an iSCSI host port on a NetApp E-Series system, you should change the maximum transmission unit (MTU) setting from its default value.
Maximum Transmission Unit (MTU): The MTU size determines the largest packet that can be sent over the network without needing to be fragmented. By increasing the MTU size, you can reduce the overhead associated with packet processing and improve throughput. For example, setting the MTU to 9000 bytes (Jumbo Frames) can enhance performance for iSCSI traffic.

NetApp Best Practices for Configuring iSCSI with E-Series
A junior administrator recently made changes to an E-Series system. As a result of these changes, the management host lost the ability to manage the E-Series system through in-band management, but the host still has access to the E-Series data volumes.
In this scenario, what caused this issue?
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.

The NetApp E-Series system with a 32 Gb FC Host Interface Card (HIC) requires which type of fiber cable to connect to switches or to connect directly to hosts extending up to 100 meters?
OM4
OM4 fiber optic cables are recommended for 32 Gb FC connections up to 100 meters due to their high bandwidth capabilities and lower attenuation, ensuring optimal performance for such high-speed connections.
