7The correct answer is D, 24 hours. CPSizeMe is a Check Point sizing script that collects performance data over time so it can give you a realistic picture of your environment under normal load, and 24 hours is the default run window because that covers a full business cycle including peak and off-peak periods. My senior engineer pointed this out when we ran it in our lab, he said anything shorter like 8 or 12 hours might miss your busiest traffic window and skew the sizing recommendations. 48 hours is longer than needed for the default, so D is the one to lock in for the exam.
The default runtime for CPSizeMe is 24 hours, which gives the tool enough time to gather a representative sample of peak and off-peak traffic patterns across a full business cycle. Remember this with the mnemonic "One Day of Data," since 24 hours equals one complete day, and that window is what Check Point recommends for accurate sizing results.
The mnemonic works, though worth flagging for the exam that the 24-hour window only gives you useful sizing data if it captures a representative day, so running CPSizeMe over a holiday or a maintenance window will skew the output even if the clock hits 24 hours.
The 48-hour option trips people up if they confuse CPSizeMe with longer-running capacity tools, but the default runtime for CPSizeMe is 24 hours, so D is your answer. Commit that number to memory before test day because they will absolutely phrase it as "by default" to see if you second-guess yourself.
Solid call to flag the "by default" wording, and here is the hook that locks 24 in forever: think "CP" as in "one full Clock Pass" around the earth, which is exactly one day, so 24 hours is baked right into the name if you squint at it right.
D is right, though 48 hours (A) lures you if you confuse it with the default eval window.
CPSizeMe runs a full day, so think "one sun cycle" and circle D, 24 hours.
