NEW QUESTION # 18
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?
- A. throughput
- B. IOPS
- C. I/O alignment
- D. parity
Answer: A
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.

Click the Exhibit button.
Referring to the exhibit, what is the total number of ALUA paths from the host to a volume on the EF280?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
* Understand ALUA Path Configuration:
* Step:Review the exhibit to determine the paths between the host and the EF280.
* Reason:ALUA (Asymmetric Logical Unit Access) provides multiple paths for redundancy and load balancing.
* Count the Paths:
* Observation:Each controller has two ports connected to two separate FC switches, and the host is connected to each switch, providing two paths per controller.
* Calculation:2 controllers x 2 paths per controller = 4 total ALUA paths.

NEW QUESTION # 24
Which two steps are required to enable multifactor authentication on an E-Series system? (Choose two.)
- A. Test SSO login
- B. Configure LDAP
- C. Configure In-Band Management
- D. Map roles
Answer: B,D
Explanation:
To enable multifactor authentication (MFA) on an E-Series system, follow these steps:
* Map roles (C):Role mapping is necessary to define the permissions and access levels for different users when MFA is enabled. This ensures that only authorized users can access specific functions and data on the system.
* Configure LDAP (D):LDAP configuration is required for integrating with directory services to manage user authentication and access control. LDAP settings need to be correctly configured to support MFA, allowing the system to authenticate users against an external directory service.

NEW QUESTION # 25
In which two locations would you find the WWPNs for a Windows host? (Choose two.)
- A. FC switch
- B. Windows Device Manager
- C. host's BIOS
- D. HBA vendor's utility
Answer: A,D
Explanation:
To find the Worldwide Port Names (WWPNs) for a Windows host, you can check the following locations:
* FC Switch (A):The WWPNs are available in the management interface of the Fibre Channel switch to which the host is connected. By accessing the switch's management tools, you can list all connected devices and their WWPNs.
* HBA Vendor's Utility (D):Host Bus Adapter (HBA) vendors typically provide utilities or management software that allows you to view the properties of the HBAs installed in the system. These utilities will display the WWPNs of the HBA ports.

NEW QUESTION # 29
An administrator is asked to provision a 1 TB volume to hold non-critical temporary data for a seismic-analysis application. The volume requires the highest possible IOPS.
In this scenario, which configuration would satisfy this requirement?
- A. RAID 6 Dynamic Disk Pool with a 32 KiB segment size
- B. RAID 6 Dynamic Disk Pool with a 256 KiB segment size
- C. RAID 0 volume group with a 32 KiB segment size
- D. RAID 5 volume group with a 256 KiB segment size
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.
