DRAG DROP
What is the correct sequence of steps taken by the storage array when an AC power failure is detected?
Select and Place:
Answer:
Explanation:
Explanation/Reference:
Explanation:
The Battery Backup Unit (BBU) provides power to the Storage Processor in the event that cabinet power is lost. The BBU is designed to power the SP long enough for the system to store SP cache content to the
M.2 SSD device before powering down. The BBU includes sensors which communicate its charge and health status to the SP. In the event the BBU is discharged the SP will disable cache until the BBU has recharged. In the event the BBU has faulted or cannot sustain enough charge, an alert will be generated.

NEW QUESTION # 181
A system administrator wants to configure asynchronous replication on their Unity system. What is required before creating a replication session?
- A. An IP-based replication interface on the same network as the destination system's replication interface.
A configured replication connection between the remote systems. - B. A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems. - C. A Sync Replication Management Port configured on each system.
An IP-based replication interface on the same network as the destination system's interface.
A configured replication connection between the remote systems. - D. A Sync Replication Management Port configured on each system.
A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems.
Answer: C
Explanation:
Explanation/Reference:
Asynchronous remote replication requires a replication interface be created on each SP on the system.
For asynchronous replication, replication is performed over Ethernet interfaces configured on the system.
On EMC Unity physical systems, the onboard 10GbE BaseT ports, CNA ports with Ethernet personality, or Ethernet ports located on I/O modules can be used for replication. In UnityVSA systems, any I/O port can be used for asynchronous replication.
NEW QUESTION # 182

- A. Name, Pool, and Storage Processor
- B. Ethernet Port, Subnet/Prefix Length, and Gateway
- C. Replication Mode, RPO, and Replicate To
- D. Management IP Address, User Name, and Password
Answer: B
Explanation:
Explanation
To create Replication interfaces for an Asynchronous Replication session, from Unisphere select Replication under the Data Protection section.Then from the Replication management page select Interfaces from the top menu.With the Interfaces section selected the + icon is used to create new Replication Interfaces. On the creation screen, an available Ethernet Port from the system must be selected. An IP address and subnet mask must be provided for both SPs. Gateway addressing is optional and a VLAN ID configuration is also provided if needed

NEW QUESTION # 186
A system administrator has configured a system using the Initial Configuration wizard. After completing the wizard, the administrator discovers that an incorrect IP address has been assigned to the Unity system.
How can the IP address be changed?
- A. In the Unisphere Settings menu
- B. The IP address cannot be changed once it has been configured
- C. Through the Service interface using the ifconfig command
- D. The IP address can only be changed using the UEMCLI
Answer: D
Explanation:
Explanation/Reference:
The svc_initial_config UEMCLI command sets up initial system configuration. It configures a management IP address when the Connection Utility (CU) is not available on the network. If an address is set, this command can also change the management IPv4 and IPv6 configuration mode. It attempts to configure the system with the given friendly name and/or network parameters.
Note: The Unisphere CLI (UEMCLI) is a tool that provides us with the CLI access to perform the same actions as one would on the Unisphere web interface.
