A service provider requires that the PE-CE link must be optimized by only compressing the TCP header in regards to Business traffic policy.
Neither voice traffic nor other traffic policies must be compressed.
Which solution meets this requirement?
The correct answer to this question is C, class-based TCP header compression.
Explanation: Class-based TCP header compression (CTHC) is a technique used to compress the TCP header to optimize the PE-CE link in a service provider network. It operates by detecting TCP traffic and compressing the TCP header only. This ensures that other types of traffic, such as voice traffic, are not affected by the compression, as required by the business traffic policy in the question.
Enhanced RTP header compression (A) is a method of compressing the RTP header used in VoIP traffic. This technique is not suitable for compressing TCP traffic, as required by the question.
Header compression using IPHC profiles (B) is a generic technique used to compress the IP header. It is not specific to TCP traffic and may compress other types of traffic, which would not meet the requirement in the question.
RTP header compression over satellite links (D) is a method of compressing the RTP header used in VoIP traffic over satellite links. This technique is not suitable for compressing TCP traffic, as required by the question.
In conclusion, the class-based TCP header compression technique would be the most appropriate solution for optimizing the PE-CE link while compressing only the TCP header and not affecting other types of traffic, as required by the business traffic policy.
