Question 1

A company implemented Automatic Load Balancing (ALB). When the controller workloads are monitored, it becomes obvious that there is an imbalance and that ALB is not working correctly.

In this scenario, what are two causes of the problem? (Choose two.)

AThe company implemented a load balancing min-min algorithm that does not support ALB

BThe company implemented an adaptive load balancing agent that does not support ALB

CThe company implemented a host multipath driver that does not support ALB

DThe company implemented a host type that does not support ALB

Answer : C, D

Understand ALB Requirements: Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.

Check Host Multipath Driver:

Verify if the host multipath driver installed supports ALB.

Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.

Review Host Type Compatibility:

Ensure the host types used in the configuration support ALB.

Certain host types might not be compatible, resulting in ALB malfunction.

Potential Causes:

Host Multipath Driver (C): If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.

Host Type (D): Incompatible host types can lead to issues with ALB implementation, causing imbalances.

Steps for Resolution:

Update or replace the host multipath driver with a version that supports ALB.

Reconfigure or update the host types to ensure compatibility with ALB.

Question 2

Which two steps are required to enable multifactor authentication on an E-Series system? (Choose two.)

ATest SSO login

BConfigure In-Band Management

CMap roles

DConfigure LDAP

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 3

A customer needs to add an EF280 with FC into its existing Brocade fabric but the FC ports in the SANtricity System Manager are showing the FC ports as down and the LED on the FC HIC is amber.

Which three tasks does the installer need to complete to solve this problem? (Choose three.)

AVerify that the ports are enabled on the switch

BVerify that the cables are plugged into the switch

CVerify that the server HBA has the boot BIOS enabled

DVerify that the EF280s management port is up

EVerify that the switch zone has the WWPNs for the EF280 and Server HBAs

Answer : A, B, E

Verify Switch Port Status:

Step: Check the status of the FC ports on the Brocade switch.

Reason: The ports need to be enabled for communication.

Check Cable Connections:

Step: Ensure that the FC cables are properly connected to the switch.

Reason: Loose or disconnected cables can cause the ports to appear down.

Verify Switch Zoning:

Step: Confirm that the WWPNs for the EF280 and server HBAs are correctly zoned in the Brocade switch.

Reason: Incorrect zoning can prevent the devices from communicating, causing the ports to appear down.

Question 4

A company wants the most scalable host-side connection topology for E-Series systems.

In this scenario, which FC topology would satisfy the requirement?

Adirect connect

Bfabric attach

Cprivate loop

Darbitrated loop

Answer : B

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.

Question 5

Which three factors should you consider before you install an E2860 in a data center? (Choose three.)

Acurrent draw

Bheat dissipation

Cfire suppression capacity

Delectromagnetic interference

Eambient temperatures

Answer : A, B, E

Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the data center power infrastructure can support it without overloading circuits.

Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center's cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.

Ambient Temperatures: The operating environment's temperature should be within the specified range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are controlled is crucial for optimal performance and longevity of the equipment.

Question 6

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?

Aby ensuring that data assurance and media scan are always activated

Bby deploying secure-capable drives

Cby turning on cyclic redundancy checks (CRCs)

Dby turning on erasure coding

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 7

What are two base host connectivity selections that are provided by the E2800 controller? (Choose two.)

AFC

BSAS

CIB

DiSCSI

Answer : A, D

The E2800 controller supports Fibre Channel (FC) and iSCSI as base host connectivity options.

FC provides high-speed connectivity for SAN environments.

iSCSI allows for IP-based storage networking, facilitating connectivity over existing Ethernet networks.
