Which of the following actions improves network reliability after firmware upgrades?

• A. Update network topology
• B. Reconfigure DNS settings
• C. Check for driver updates
• D. Downgrade firmware versions

Answer: (D)

Downgrading firmware versions can improve network reliability in certain situations, particularly if the new firmware introduces bugs or incompatibilities that negatively impact the performance or stability of the network devices. When a firmware upgrade is performed, it can sometimes lead to unexpected behavior due to changes in the underlying code, which may not have been thoroughly tested in all environments. If users experience issues after the upgrade, reverting to a previous, stable version of the firmware can restore functionality and improve overall network reliability by eliminating the problems introduced by the new version. In practice, this action is particularly useful when it’s clear that the newly updated firmware is at fault and that the prior version was functioning correctly. It allows administrators to maintain a stable and reliable network while further troubleshooting or waiting for a more stable firmware build.
