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.)
Target username and password: These credentials are used by the initiator to authenticate to the target.
Initiator username and password: These credentials are used by the target to authenticate the initiator.
CHAP: Challenge-Handshake Authentication Protocol is used to set up the authentication mechanism.
Modifications in the /etc/iscsi/iscsid.conf file include setting the appropriate values for these parameters.
Reference: NetApp iSCSI Configuration Guide for Linux, which details the configuration of CHAP and other authentication methods.
You help a customer diagnose a performance issue on an E-Series storage system. You decide to measure the amount of data that is being handled over the span of an hour.
In this scenario, what are you measuring?
Definition of Throughput: Throughput refers to the amount of data transferred from or to the storage system over a specific period. It is measured in units such as MB/s or GB/s.
Relevance to Performance Diagnosis: When diagnosing performance issues on an E-Series storage system, measuring throughput over an hour helps determine the data handling capacity of the system. This metric can reveal whether the system is processing data efficiently or if there are bottlenecks.
Methodology: Tools within the SANtricity System Manager can be used to monitor and log throughput, providing insights into the performance characteristics and potential areas needing optimization.

Which command on a NetApp storage controller will display the average service time on a FC target port basis every five seconds?
Purpose: To display the average service time on a FC target port basis.
Command: fcp stats -i 5
Usage: Monitors Fibre Channel Protocol (FCP) performance, including service times for FC target ports at specified intervals (every 5 seconds in this case).

Which two actions must be performed to enable iSCSI multipathing on Windows for NetApp E-Series systems? (Choose two.)
iSCSI Multipathing: Enables multiple paths for data to travel between the host and storage, providing redundancy and increased performance.
Steps to Enable:
iSCSI IP Setup: Configure IP addresses for the iSCSI interfaces on both the E-Series system and the Windows host to ensure proper network communication.
Host Utilities: Install NetApp E-Series Host Utilities on the Windows host to provide the necessary drivers and multipathing software.
Your company has an E-Series system connected to Cisco MDS switches. You are asked to provision a volume on a new Windows host, but the Windows host is unable to connect to the volume on the E-Series system. All other Windows hosts in the fabric are able to connect to their volumes.
In this scenario, which three actions should you perform to accomplish this task? (Choose three.)
To resolve the issue of a new Windows host being unable to connect to a volume on the E-Series system when all other hosts can, follow these steps:
Obtain the WWPN for the Windows HBA (B): The Worldwide Port Name (WWPN) is essential for zoning and establishing communication between the host and the storage system. Ensure you have the correct WWPN for the new Windows host's HBA.
Create a single-initiator zone with the host and E-Series system (D): Zoning is crucial in SAN environments to control and secure the data paths. Create a single-initiator zone that includes the WWPN of the Windows host and the target ports of the E-Series system. This ensures that the host can see the storage.
Add a zone to the active zoneset (E): After creating the necessary zone, it needs to be added to the active zoneset on the Cisco MDS switch. The zoneset must then be activated for the changes to take effect, enabling the new host to communicate with the E-Series system.
These steps ensure that the new Windows host is properly zoned and can access the storage volumes without disrupting the existing configurations.
