RedHat EX200 Practice Test 96

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?

  1. Neighbor and route checks recognize the intended on-link destinations.
  2. `ip -6 route` shows the intended default path and external IPv6 tests succeed.
  3. The intended profile activates and uses correct address and routes at startup.
  4. Route lookup and neighbor resolution follow the intended subnet boundaries.

Explanation

Correct Answer

A:

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

B:

`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.

C:

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.

D:

Question 951

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 system administration principle best explains this behavior?

  1. Address assignment and default route acquisition are distinct capabilities.
  2. IPv6 prefix lengths define local network scope just as IPv4 masks do.
  3. Competing eligible connection profiles can affect automatic selection.
  4. Prefix lengths define which destination addresses are locally reachable.

  3. Validate subnet masks against address management records.
  4. Validate address and prefix together.

Question 953

Original unofficial RHEL 10 RHCSA skill-check scenario: A host has a valid global IPv6 address but no default IPv6 route to external services. Which action best addresses this situation?

Question 957

Original unofficial RHEL 10 RHCSA skill-check scenario: An operator copies a link-local IPv6 next hop to another interface without identifying its scope. Which action best addresses this situation?

  1. Configure the correct IPv6 prefix length for the NetworkManager connection.
