Predictive scaling overview in AWS - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable predictive scaling for an Auto Scaling group.

AWS

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg --policy-name predictive-policy --policy-type [1]

Drag options to blanks, or click blank then click option'

CTargetTrackingScaling

DStepScaling

💡 Hint

Common Mistakes

Using SimpleScaling instead of PredictiveScaling

Confusing TargetTrackingScaling with predictive scaling

The policy type must be PredictiveScaling to enable predictive scaling.

medium

Complete the code to specify the maximum capacity for predictive scaling.

AWS

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg --policy-name predictive-policy --policy-type PredictiveScaling --predictive-scaling-configuration MaxCapacityBehavior=[1]

Drag options to blanks, or click blank then click option'

AHonorMaxCapacity

BIgnoreMaxCapacity

CHonorDesiredCapacity

DIgnoreDesiredCapacity

Attempts:

💡 Hint

Common Mistakes

Using IgnoreMaxCapacity which can cause scaling beyond limits

Confusing desired capacity behavior with max capacity

HonorMaxCapacity ensures the predictive scaling respects the maximum capacity set for the group.

hard

Fix the error in the predictive scaling configuration to set the scheduling buffer time.

AWS

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg --policy-name predictive-policy --policy-type PredictiveScaling --predictive-scaling-configuration SchedulingBufferTime=[1]

Drag options to blanks, or click blank then click option'

Afive_minutes

B"300"

C0.3

D300

Attempts:

3 left

💡 Hint

Common Mistakes

Using a string instead of an integer

Using a float or descriptive string instead of seconds

The SchedulingBufferTime must be an integer number of seconds, so 300 (5 minutes) is correct.

4fill in blank

hard

Fill both blanks to configure predictive scaling with a customized metric and target value.

AWS

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg --policy-name predictive-policy --policy-type PredictiveScaling --predictive-scaling-configuration PredefinedMetricSpecification=[1], TargetValue=[2]

Drag options to blanks, or click blank then click option'

A"ASGAverageCPUUtilization"

B50.0

C"ALBRequestCountPerTarget"

D100.0

Attempts:

3 left

💡 Hint

Common Mistakes

Using ALBRequestCountPerTarget metric with a CPU target value

Setting target value as a string instead of a number

Use ASGAverageCPUUtilization as the predefined metric and set the target value to 50.0 percent.

5fill in blank

hard

Fill all three blanks to create a predictive scaling policy with a customized metric, target value, and disable scale-in.

AWS

aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg --policy-name predictive-policy --policy-type PredictiveScaling --predictive-scaling-configuration PredefinedMetricSpecification=[1], TargetValue=[2], DisableScaleIn=[3]

Drag options to blanks, or click blank then click option'

A"ASGAverageNetworkIn"

B75.0

Ctrue

Dfalse

Attempts:

3 left

💡 Hint

Common Mistakes

Using false instead of true for DisableScaleIn

Mixing metric and target value types

Use ASGAverageNetworkIn as the metric, set target value to 75.0, and disable scale-in by setting true.
