Question 940
Original unofficial RHEL 10 RHCSA skill-check scenario: A data interface uses DHCP but a script hardcodes a static IPv4 address on the same connection, causing conflicts. Which ongoing practice best prevents a recurrence?
Explanation
Correct Answer
In this RHEL 10 system administration case: A data interface uses DHCP but a script hardcodes a static IPv4 address on the same connection, causing conflicts. Underlying reason: Mixing DHCP and unmanaged static state can produce ambiguous interface configuration. The most direct, approved resolution is: Set the NetworkManager IPv4 method intentionally and remove conflicting unused static configuration. Confirm it by checking: The connection acquires or uses the exact approved address without duplicates. Sustain the fix by: Keep a single source of truth for each network profile. This is the INTENDED response for the best ongoing operational safeguard. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
Incorrect Answers
Validate subnet masks against address management records. That is not sufficient for the reported RHEL task, because mixing DHCP and unmanaged static state can produce ambiguous interface configuration.
Check IPv6 route presence after network changes. That is not sufficient for the reported RHEL task, because mixing DHCP and unmanaged static state can produce ambiguous interface configuration.
Apply naming changes through approved system configuration. That is not sufficient for the reported RHEL task, because mixing DHCP and unmanaged static state can produce ambiguous interface configuration.
