A network administrator is reviewing packet capture data and interface configurations to verify IPv6 protocol operations across an enterprise network. Which of the following statements regarding IPv6 header fields and address representation rules are correct? (Select TWO.)
- The Flow Label field in the base IPv6 header is a 20-bit field used to identify packets belonging to a specific communication flow for Quality of Service (QoS) handling.Cevap
- BThe IPv6 shorthand representation `2001:db8::1000::1` is a valid syntax for zero compression.
- The Next Header field in the base IPv6 header specifies the type of header immediately following the base header, serving a function equivalent to the IPv4 Protocol field.Cevap
- DThe Hop Limit field in the base IPv6 header specifies the maximum payload size in bytes that can traverse a router link.
Cevap
The statement regarding the 20-bit Flow Label field used for QoS flow identification and the statement regarding the Next Header field specifying the subsequent header type (equivalent to the IPv4 Protocol field) are correct.
The correct choices accurately identify that the 20-bit Flow Label field identifies traffic flows for QoS without inspecting payload contents, and that the Next Header field indicates the protocol or extension header following the base IPv6 header, replacing the IPv4 Protocol field.
