• Question 456:

  Which compression algorithm does DRE use in a Cisco SD-WAN environment?

  A. Lempel-Ziv-Welch encoding

  B. Huffman encoding

  C. run-length encoding

  D. Ziv Huffman encoding

  Correct Answer: A

  DRE Compression: DRE uses the Lempel-Ziv-Welch (LZW) compression algorithm for compressing data. DRE operates on large streams of data, typically tens to hundreds of bytes or more, and maintains a much larger compression history.
