SK0-003 · Question #295
A technician has a current baseline and is told to install additional memory and a faster NIC card. At which point in time should the next baseline be run?
The correct answer is D. After the upgrades are performed. A new system baseline should be established only after all planned hardware upgrades are completed and verified to reflect the new normal operational state.

Why each option
A new system baseline should be established only after all planned hardware upgrades are completed and verified to reflect the new normal operational state.
Running a baseline after only the memory is installed would not account for the changes introduced by the NIC card upgrade, making the baseline incomplete.
Running a baseline before the upgrade would capture the system's old state, which is no longer relevant for monitoring after the upgrades are performed.
Running a baseline after only the NIC is installed would not account for the changes introduced by the memory upgrade, making the baseline incomplete.
A baseline provides a snapshot of a system's normal performance and configuration. Since both memory and NIC card upgrades will change the system's performance characteristics, running a new baseline after all modifications are fully implemented and stable accurately reflects the system's new operational state for future comparison.
