B) Existing data is left in its current state.
C) Existing data is dynamically inflated to its full size, undoing the impact of deduplication and compression.
D) Data Reduction, once enabled, cannot be disabled. New data is deduplicated or compressed.

A) Disabled for thick LUNs and enabled for thin LUNs
B) Disabled for thin LUNs in an All-Flash pool
C) Enabled for thin LUNs in an All-Flash pool
D) Enabled for both thick and thin LUNs

Accepted Answer

Advanced Deduplication is typically enabled by default for thin LUNs in an All-Flash pool to optimize storage efficiency.

Question 10

What is a consideration when specifying a Dial Home suppression time for a Dell EMC Unity XT storage array?
A) Can be lengthened or shortened
B) The time zone where the array is located
C) Should be set between 1 and 32 hours
D) Can be enabled at any time

Accepted Answer

The Dial Home suppression time should be set between 1 and 32 hours to control the frequency of alerts sent to Dell EMC support.

Question 11

Which UEM/CLI command is used to verify the FC ports designated as synchronous on the SPs?
A) /remote/sys show -lc
B) /remote/sys show -detail
C) /remote/sys show -summary
D) /remote/sys show -sp

Accepted Answer

The command "/remote/sys show -detail" provides detailed information about the system, including the status of FC ports, which can be used to verify if they are designated as synchronous on the SPs.

Question 12

What is a connectivity rule for a host that connects to multiple Dell EMC Unity systems?
A) Host must connect to all the arrays using a single protocol
B) Host can connect to different arrays with different protocols
C) iSCSI protocol is required to connect a host to multiple arrays
D) CNA connections to host must be used with alternating protocols

Accepted Answer

A host can connect to different Dell EMC Unity systems using different protocols, allowing flexibility in how storage resources are accessed.

Question 13

What is the recommended configuration for iSCSI connections to ensure continuous access to the Dell EMC Unity XT storage system in the event of a failover?
A) Create iSCSI interfaces on different network ports on the same SP that are combined into a link aggregation
B) Set up iSCSI interfaces on the same port of each SP and leverage the host-based multi-pathing software
C) Set up iSCSI interfaces on the same port of each SP and configure advanced static routes for the interfaces
D) Create iSCSI interfaces on network ports on different SPs that are combined into a FSN logical device
