Question 1
What is the minimum number of drives needed to create a Dynamic Disk Pool?
Answer : A
To create a Dynamic Disk Pool (DDP), the minimum number of drives required is 12. This minimum requirement ensures that there is enough capacity and redundancy to maintain the performance and data protection characteristics that DDPs provide.
Dynamic Disk Pools are designed to optimize data distribution and rebuild times. By using 12 drives as a baseline, the system can efficiently distribute data and parity information across the drives, improving fault tolerance and rebuild performance compared to traditional RAID configurations.

Question 2
A customer has launched a data analytics initiative and has been transferring old data into the new data lake. The customer has discovered some data read errors during the transfer process.
In this scenario, how should the customer have avoided these data integrity issues?
Answer : A
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.

Question 3
Click the Exhibit button.
You ordered a NetApp E2812 Duplex 16GB 10 GbE Base-T system.
Referring to the exhibit, what is the maximum number of 10GbE Base-T ports available to be used?
Answer : B
The exhibit shows the supported adapter cards for the E2812 system with specific marketing part numbers.
The E2812 system ordered is a Duplex 16Gb 10GbE Base-T system with the adapter card part number X-56023-00-0E-C, which is described as 'HIC.E2800.10Gb Base-T.2-ports, -C'.
Each card provides 2 ports.
Given that the system is duplex, it means it has two controllers, each capable of supporting one card.
Therefore, each controller can have one 10GbE Base-T card with 2 ports, resulting in a maximum of 4 ports available in total for the system.

Question 4
Which two steps are required to enable multifactor authentication on an E-Series system? (Choose two.)
Answer : C, D
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.

Question 5
Which alerting method would be configured using the SANtricity System Manager setup wizard?
Answer : D
When configuring alerting methods using the SANtricity System Manager setup wizard, the option you configure is Email.
Email: The setup wizard in SANtricity System Manager provides an option to configure email notifications. This involves specifying the email server details, sender address, and recipients to ensure that alerts and notifications about the system's status, errors, and other critical events are sent via email.

Question 6
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?
Answer : A
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.

Question 7
What is represented by the Headroom graph on the SANtricity System Manager performance tab?
Answer : B
The Headroom graph in SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.
This helps in understanding how much additional load the system can handle before reaching its performance limits.
