Question 950
Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator adds a static IPv6 address without the intended prefix and the host cannot reach other nodes in the subnet. Which observation best confirms the intended outcome?
Explanation
Correct Answer
In this RHEL 10 system administration case: An administrator adds a static IPv6 address without the intended prefix and the host cannot reach other nodes in the subnet. Underlying reason: IPv6 prefix lengths define local network scope just as IPv4 masks do. The most direct, approved resolution is: Configure the correct IPv6 prefix length for the NetworkManager connection. Confirm it by checking: Neighbor and route checks recognize the intended on-link destinations. Sustain the fix by: Validate address and prefix together. This is the INTENDED response for the strongest objective verification result. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
Incorrect Answers
`ip -6 route` shows the intended default path and external IPv6 tests succeed. That is not sufficient for the reported RHEL task, because IPv6 prefix lengths define local network scope just as IPv4 masks do.
The intended profile activates and uses correct address and routes at startup. That is not sufficient for the reported RHEL task, because IPv6 prefix lengths define local network scope just as IPv4 masks do.
Route lookup and neighbor resolution follow the intended subnet boundaries. That is not sufficient for the reported RHEL task, because IPv6 prefix lengths define local network scope just as IPv4 masks do.
