RedHat EX200 Practice Test 94

Question 930

Original unofficial RHEL 10 RHCSA skill-check scenario: A new server receives a static IPv4 address but its NetworkManager connection has no default gateway. Which observation best confirms the intended outcome?

  1. `ip route` lists the intended default route and off-subnet tests succeed.
  2. Route lookup and neighbor resolution follow the intended subnet boundaries.
  3. Resolver lookups return the intended current service IP.
  4. `ip -6 route` shows the intended default path and external IPv6 tests succeed.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: A new server receives a static IPv4 address but its NetworkManager connection has no default gateway. Underlying reason: An IP address alone does not provide a route to remote networks. The most direct, approved resolution is: Set the approved IPv4 gateway in the correct `nmcli connection` profile and activate it safely. Confirm it by checking: `ip route` lists the intended default route and off-subnet tests succeed. Sustain the fix by: Include gateway checks during interface configuration. 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:

Route lookup and neighbor resolution follow the intended subnet boundaries. That is not sufficient for the reported RHEL task, because an IP address alone does not provide a route to remote networks.

C:

Resolver lookups return the intended current service IP. That is not sufficient for the reported RHEL task, because an IP address alone does not provide a route to remote networks.

D:

`ip -6 route` shows the intended default path and external IPv6 tests succeed. That is not sufficient for the reported RHEL task, because an IP address alone does not provide a route to remote networks.

Question 931

Original unofficial RHEL 10 RHCSA skill-check scenario: A new server receives a static IPv4 address but its NetworkManager connection has no default gateway. Which system administration principle best explains this behavior?

  1. Prefix lengths define which destination addresses are locally reachable.
  2. Local static host mappings can take precedence over DNS results.
  3. An IP address alone does not provide a route to remote networks.
  4. Address assignment and default route acquisition are distinct capabilities.

Question 933

Original unofficial RHEL 10 RHCSA skill-check scenario: An operator assigns an IPv4 address with the wrong prefix length, treating an off-subnet server as local. Which action best addresses this situation?
