NEW QUESTION 7
At which stage in the Unity power up sequence would the Storage Processor enter Service mode upon detecting an error?

• A. After the CMI is started
• B. Bootflash
• C. POST
• D. BIOS

Answer: C

Explanation:
Note: Boot counters are a troubleshooting mechanism that is designed into the Unity architecture to help pinpoint the specific cause of software or hardware events during the boot sequence. If the Unity system detects a problem with software or hardware components, its corresponding Boot Counter is incremented. If a counter reaches a predefined threshold, the SP boots into Service Mode during its next boot cycle.

Answer: A

Explanation:
A pool type introduced in Dell EMC Unity OE version 4.2toprovide space to storage resources. Dynamic pools allow for flexible deployment models, and reduced rebuild times and flash wear compared to Traditional pools. A dynamic pool is created when creating a pool in Unisphere in Dell EMC Unity OE version 4.2 and
later. Dynamic pools are only supported on Dell EMC Unity all-flash systems.

NEW QUESTION 9
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. The IP address cannot be changed once it has been configured
• B. Through the Service interface using the ifconfig command
• C. In the Unisphere Settings menu
• D. The IP address can only be changed using the UEMCLI

Answer: D

Explanation:
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.

In Unisphere, a storage administrator has inadvertently disabled Data Reduction on an existing LUN.
What would result from this action?

• A. A background LUN migration occurs, moving the data to a new LUN where it is inflated.New data is neither deduplicated nor compressed.
• B. Existing data is left in its current state.New data is neither deduplicated nor compressed.
• C. Existing data is dynamically inflated to its full size, undoing the impact of deduplication and compression.New data is neither deduplicated nor compressed.
• D. Data Reduction, once enabled, cannot be disabled.New data is deduplicated or compressed.

Answer: B

NEW QUESTION 12
What are characteristics of the LUN Snapshot Copy operation?

• A. Parent cannot be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent
• B. Parent can be a snapshot copyCan only copy a detached snapshotHas an independent Retention Policy from the parent
• C. Parent can be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy
• D. Parent cannot be a snapshot copyCan copy an attached or detached snapshotInherits the parent Snapshot Retention Policy

Answer: D

Explanation:
The Snapshot Copy operation will make a copy of an existing snapshot that is either attached or detached from a host. The copy will capture the existing data state of the snapshot it copies. In this Copy example, a copy of an existing 4 o clock snapshot is being made. The copy inherits the parent snapshot data state of 4 o clock and its retention policy
