A rightsizing workshop finds idle extra-large EC2 instances that monitoring shows should be medium. What action matches rightsizing best?
Select an answer to reveal the explanation.
Short Explanation
Finding idle XLs that should be mediums is like noticing you rented a banquet hall for a desk for one. Rightsizing fixes the size to the need — it is not “buy Reserved first and think later.” Look, then fit, then commit if it still makes sense.
Full Explanation
Rightsizing uses utilization evidence to match resources to need. Committing to Reserved pricing without reviewing oversized idle capacity can lock in waste. Cloud Practitioner economics stresses fit-to-need adjustments as a primary practice before or alongside commitment discounts.
