After setting up an SC4020 and turning on the system, both controllers initialize to Safe Mode and are ready for configuration You plug the serial cable into the first controller and type the platform prejoin show command You then receive the command output shown in the exhibit

If you continued configuring the controller, what are the reasons why the deployment will fair?

• A.Serial cable needs to be plugged into the top controller eth1 IPv4 IP address used at the factory to load the firmware was not cleared before shipping
• B.Serial cable needs to be plugged into the top controller Controller chassis is installed upside down in the rack
• C.Serial cable needs to be plugged into the bottom controller eth1 IPv4 IP address used at the factory to load the firmware was not cleared before shipping
• D.Serial cable needs to be plugged into the bottom controller Controller chassis is installed upside down in the rack

A company experienced complete storage outages on some of their servers. The outages occurred when network maintenance was performed within their iSCSI network. Which configuration areas should be investigated to prevent future outage?

• A.Ensure the servers are set up for multipathing with Round Robin.
  Ensure Deplayed Acknowledgment has been disabled on the iSCSI dapters.
• B.Ensure Delayed Acknowledgment has been disabled on the iSCSI adapters.
  Ensure all server iSCSI adapter are able to communicate with the storage.
• C.Ensure the iSCSI adapters are set up for Jumbo Frames.
  Ensure all server iSCSI adapters are able to communicate with the storage.
• D.Ensure the servers are set up for multipagthing with Round Robin
  Ensure all server iSCSI adapters are able to communicate with the storage.

A storage administrator has an 8 TB database. Half of the data is hot and frequently accessed. The other half of the data is older with infrequently used cold dat a. The administrator purchased 12, 800 GB SLC SSDs and placed them in a new disk folder called
"Database".
The administrator then created volumes for this database in the Database disk folder using the recommended storage profile. After the database had been running for one month, the Statistics tab for the database volumes showed 100% of the space is on Tier 1. However, the administrator expected that half of the data would be on Tier 1 and the rest would be moved to lower tiers.
What are the reasons for this issue?

• A.Data Progression does not run on database volumes
  Database vendors have specific requirements for laying out their data across tiers
• B.Recommended storage profile will only use SSD tiers if any are available Cold data cannot move to the lower tier disks
• C.Volumes were created in the Database disk folder
  Data Progression cannot move the cold data to the lower tier disks
• D.Sufficient space is available on Tier 1 for the entire 8 TB database Event cold data will remain on Tier 1 until it becomes full

After configuring a new SC4020, you receive an alert that all disks are only seen on one path. What are the reasons for the alert?

• A.One SAS cable was not connected between the controllers and one SAS cable is defective
• B.One SAS cable was not connected between the controllers and the alert definition was configured incorrectly.
• C.Both SAS cables are defective and the alert definition was configured incorrectly.
• D.One SAS cable is defective and the other path to the disks was not managed

Based on best practices, an SC Series storage array, network, and servers have been successfully installed and configured. The impact of failing various devices and connections must be tested to validate that there is no single point of failure in the environment.
The environment consists of the following:

What are the available environment redundancy tests that can be performed?

• A.Remove power from one of the switches, disconnect both server iSCSI interfaces, and remove all iSCSI
• B.Remove all SAS cables form one controller, disconnect both server iSCSI interfaces, and remove all iSCSI cables form one controller
• C.Restart one controller, remove power from one of the switches, and remove one power cable from each device
• D.Restart one controller, remove all SAS cables form one controller, and remove one power cable from each device
