AWS - Auto Scaling

You want to reduce your AWS Auto Scaling group capacity to 2 instances every night at 11 PM UTC and increase it to 10 instances every weekday morning at 7 AM UTC. Which setup correctly uses scheduled scaling to achieve this?

ACreate one scheduled action with cron(0 23,7 * * ? *) setting DesiredCapacity=2 and DesiredCapacity=10

BCreate two scheduled actions: one with cron(0 23 * * ? *) setting DesiredCapacity=2, another with cron(0 7 ? * MON-FRI *) setting DesiredCapacity=10

CCreate two scheduled actions: one with rate(1 day) setting DesiredCapacity=2, another with rate(1 hour) setting DesiredCapacity=10

DCreate one scheduled action with cron(0 7 * * ? *) setting DesiredCapacity=10 only

Step-by-Step Solution

Solution:

Step 1: Understand the scheduling requirements
Capacity should be 2 at 11 PM daily and 10 at 7 AM on weekdays only.
Step 2: Match cron expressions to requirements
cron(0 23 * * ? *) runs daily at 11 PM; cron(0 7 ? * MON-FRI *) runs at 7 AM Monday to Friday. Two separate scheduled actions are needed with correct DesiredCapacity values.
Final Answer:
Create two scheduled actions: one with cron(0 23 * * ? *) setting DesiredCapacity=2, another with cron(0 7 ? * MON-FRI *) setting DesiredCapacity=10 -> Option B
Quick Check:
Separate cron for each time and capacity [OK]

Quick Trick: Use separate scheduled actions with correct cron and capacity [OK]

Common Mistakes:

Trying to set two capacities in one scheduled action
Using rate expressions instead of cron for weekdays
Missing weekday restriction for morning scale-up
