JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2022) — Question 11

Which IPv6 extension header notifies intermediary devices that they must inspect the packet's options?

Answer options

• A. destination options header
• B. routing header
• C. hop-by-hop options header
• D. fragment header

Correct answer: B

Explanation

The correct answer is B, the routing header, as it specifies that routers should process the options in the packet. The destination options header (A) and hop-by-hop options header (C) have different purposes, while the fragment header (D) is used for packet fragmentation and does not require inspection of options.
