101 · Question #376

Which WOM feature replaces a long byte pattern, such as "100000111000110101", with a shorter reference to the pattern?

The correct answer is B. Symmetric data deduplication. Symmetric data deduplication identifies repeated byte sequences in WAN traffic and substitutes a short reference token, reducing the volume of data transmitted.

Why each option

Symmetric data deduplication identifies repeated byte sequences in WAN traffic and substitutes a short reference token, reducing the volume of data transmitted.

ASymmetric adaptive compression

Symmetric adaptive compression reduces data size using encoding algorithms applied to the data stream, but does not replace specific recurring byte patterns with dictionary references.

BSymmetric data deduplicationCorrect

Symmetric data deduplication works by having WOM devices on both ends of the WAN maintain a shared dictionary of previously seen byte patterns. When a known pattern is encountered, it is replaced with a much shorter reference token before transmission, and the receiving device reconstructs the original data - directly matching the description of replacing a long byte pattern with a shorter reference.

CBandwidth allocation

Bandwidth allocation controls how WAN capacity is distributed across traffic classes and has no role in pattern-based data substitution.

DApplication protocol acceleration

Application protocol acceleration reduces protocol overhead and round trips at the application layer, not byte-level pattern replacement.

ETCP optimization

TCP optimization improves connection efficiency through techniques like window scaling and connection reuse, not byte-pattern deduplication.
