Which of the following descriptions about OceanProtect's dedicated backup storage deduplication and compression technology is incorrect?

Question

Options

• AThe first step is to preprocess the backup data and separate the data header and changed data.
• BThe fourth step is byte-level compression technology
• CThird step is feature-based Compression. The second step is feature-based compression of
• DThe second step is multi-layer online fixed-length deduplication of backup data.

• A
  71% (17)
• B
  8% (2)
• C
  4% (1)
• D
  17% (4)

Explanation

Option A is marked incorrect because OceanProtect's first step is data stream segmentation/chunking - not preprocessing to separate "data headers and changed data." That description doesn't match any actual step in the pipeline, making it the false statement.

Options B, C, and D are all accurate descriptions: the pipeline follows a four-step sequence - (1) segmentation, (2) multi-layer online fixed-length deduplication (D), (3) feature-based compression (C), and (4) byte-level compression (B) - so those three distractors correctly describe their respective steps.

Memory tip: Use the acronym S-D-F-B (Segment → Deduplicate → Feature-compress → Byte-compress) to lock in the order. If an answer describes step 1 as anything other than segmentation, it's the wrong one.
