Given an Auto Scaling group with MinSize=2, MaxSize=6, and DesiredCapacity=4, what happens if the current number of running servers is 5 and one server fails?
AThe group does nothing because the current number of running servers equals DesiredCapacity
BThe group launches a new server to maintain DesiredCapacity of 4
CThe group terminates another server to reach DesiredCapacity
DThe group launches two new servers to reach MaxSize
Step-by-Step Solution
Solution:
Step 1: Understand DesiredCapacity role
DesiredCapacity is the target number of servers to keep running, here 4.
Step 2: Analyze failure impact
One server fails, so running servers drop from 5 to 4, which matches DesiredCapacity.
Step 3: Check if scaling needed
Since running servers dropped below DesiredCapacity, the group launches a new server to maintain DesiredCapacity.
Final Answer:
The group launches a new server to maintain DesiredCapacity of 4 -> Option B
