A customer wants to migrate their data from an existing AMS2500 to a newly acquired Hitachi Unified Storage (HUS) system using TrueCopy Extended Distance (TCE) software. Which set of components is…

Question

Options

• AJournal Volumes and a TCE license
• Ban HDP license and 50% more cache capacity
• Can HDP License and a TCE license
• Da Cache Memory adapter and a TCE license

• A
  6% (2)
• B
  3% (1)
• C
  75% (24)
• D
  16% (5)

Explanation

Configuring TrueCopy Extended Distance on HUS requires both an HDP (Hitachi Dynamic Provisioning) license and a TCE license because TCE on the HUS platform uses HDP-based journal volumes for its asynchronous replication mechanism - HDP must be licensed first to create the virtual volumes that serve as journals. Option A is wrong because listing "Journal Volumes" as a component misidentifies the prerequisite (HDP enables those journals) and omits it. Option B is wrong because extra cache capacity is not a documented TCE requirement, and HDP alone provides no replication capability. Option D is wrong because a Cache Memory adapter is a generic hardware component, not a TCE-specific requirement, and cache hardware changes won't enable the replication software.

Memory tip: Think "HDP builds the Highway, TCE drives the truck" - on HUS, HDP lays the virtual volume infrastructure TCE travels on, so you always need both licenses together.
