Important NetApp NS0-516 Exam Questions

Answer: C

Explanation:

The multipath configuration file for Fibre Channel (FC) on Linux systems is typically /etc/multipath.conf.

This file is used to define multipath settings and policies, such as path grouping, path selection, and failover behavior.

Answer: B

Explanation:

Fabric attach FC topology is the most scalable host-side connection topology for E-Series systems.

This topology involves connecting the E-Series storage system to a Fibre Channel switch, which then connects to the hosts.

Scalability: The fabric attach topology supports a large number of devices by allowing multiple switches to be interconnected, forming a fabric.

Redundancy: It offers higher redundancy and failover capabilities because multiple paths can be created between the hosts and the storage.

Answer: A

Explanation:

Data integrity issues can often be prevented by ensuring that mechanisms for data assurance and media scanning are activated.

Data Assurance (DA) is a feature that verifies the integrity of the data as it is read from or written to the storage system, detecting and correcting errors.

Media scan is a background process that checks the entire disk surface for errors and corrects any found before they cause data integrity issues.

Together, these features ensure ongoing data integrity by preemptively identifying and fixing potential issues.

Answer: B

Explanation:

Cabling method: It is important to distribute the connections for redundancy and balanced performance.

EXP1 and EXP2 ports: By dividing these ports between the A-side and B-side IOM-12 modules, the system ensures balanced load and failover capabilities.

Answer: C

Explanation:

Understanding the Requirements: The administrator needs to provision a 1 TB volume for non-critical temporary data that requires the highest possible IOPS.

Non-Critical Data: Since the data is non-critical, redundancy (data protection) is not the primary concern. Therefore, RAID 0, which does not provide redundancy but maximizes performance, is suitable.

Highest Possible IOPS: RAID 0 is known for providing the highest IOPS compared to other RAID levels because it stripes data across multiple disks, allowing simultaneous read/write operations.

Segment Size: A smaller segment size (32 KiB) will result in higher IOPS for small random I/O operations, which is typical in seismic-analysis applications.
