NEW QUESTION # 12
During SANtricity System Manager configuration, an administrator notices the "Unnamed Discovery Domain" warning for iSCSI hosts. What does this indicate?
Answer: C
Explanation:
Discovery domains (used with iSNS) logically group iSCSI initiators and targets to control which devices can discover each other. An "Unnamed Discovery Domain" warning simply indicates that domains haven't been explicitly organized/named, which is a configuration/organizational notice rather than a connectivity failure.
NEW QUESTION # 13
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.)
Answer: C,D,E
Explanation:
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.

NEW QUESTION # 14
An E2812 system, without expansion shelves, is configured with 12 Gb SAS host interface cards (HICs) and is directly connected to a host. However, the host cannot access the volumes.
In this scenario, which two troubleshooting steps should you take? (Choose two.)
Answer: A,B
Explanation:
Verify that the E2812 host port SAS link up lights are illuminated
* Explanation: The link up lights on the E2812 host port should be checked to confirm that the physical layer connection is established. If the lights are not illuminated, it indicates that there is no physical link between the host and the E2812 system, which would explain why the host cannot access the volumes.
NEW QUESTION # 15
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.)
Answer: B,C,E
Explanation:
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.
NEW QUESTION # 16
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?
Answer: B
Explanation:
* 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.
