💡 Hint

Common Mistakes

Using "on-demand" instead of "spot" will launch regular instances without cost savings.

Misspelling "spot" (such as using uppercase letters) causes errors.

The MarketType must be set to "spot" to request Spot Instances, which are cheaper than On-Demand instances.

Complete the code to set the maximum price you are willing to pay per hour for a Spot Instance.

💡 Hint

Common Mistakes

Setting MaxPrice too high loses cost savings.

Using a number instead of a string causes errors.

The MaxPrice should be set to a low value like "0.03" to save costs, representing the maximum hourly price you accept.

Fix the error in the Spot Instance request code by completing the missing key for interruption behavior.

AWS

"SpotOptions": {"InterruptionBehavior": "[1]"}

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

💡 Hint

Common Mistakes

Using "pause" which is not a valid interruption behavior.

Capitalizing the first letter causes errors.

The valid interruption behaviors are "terminate", "stop", or "hibernate". "terminate" immediately ends the instance when interrupted.

Fill both blanks to configure a Spot Instance request with a valid instance type and a valid Spot allocation strategy.

AWS

"InstanceType": "[1]", "SpotOptions": {"AllocationStrategy": "[2]"}

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

💡 Hint

Common Mistakes

Using an invalid instance type like "t2.nano" which may not be supported in all regions.

Choosing "lowest-price" which can cause more interruptions.

"t3.micro" is a valid instance type for cost savings. "capacity-optimized" is a recommended Spot allocation strategy to reduce interruptions.

Fill all three blanks to create a Spot Instance request with a launch template name, Spot market type, and interruption behavior.

AWS

"LaunchTemplateName": "[1]", "InstanceMarketOptions": {"MarketType": "[2]", "SpotOptions": {"InterruptionBehavior": "[3]"}}

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

💡 Hint

Common Mistakes

Using "on-demand" instead of "spot" for MarketType.

Choosing invalid interruption behaviors.

Use a valid launch template name like "my-spot-template". Set MarketType to "spot" to request Spot Instances. Set InterruptionBehavior to "terminate" to end the instance on interruption.
