TechnologyhardMultiple ChoiceObjective-mapped

Quick Answer

The answer is to set the 'Delete on Termination' attribute to 'True' on all EBS volumes attached to the instance when it is launched by LaMa. This flag, when enabled on both root and additional EBS volumes at launch time, instructs AWS to automatically delete those volumes the moment the EC2 instance is terminated, directly solving the orphaned volume problem during SAP LaMa scale-in operations. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how LaMa interacts with EC2 lifecycle hooks and EBS volume attributes; a common trap is assuming that Lambda or Lifecycle Manager is needed, but the simplest native solution is the launch-time flag. Remember the memory tip: "Set it and forget it at launch" — if you don't set the flag before the instance starts, termination won't clean up the volumes.

PAS-C01 Technology Practice Question

This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company is using SAP Landscape Management (LaMa) to automate the provisioning and decommissioning of SAP application servers in an AWS environment. The SAP systems are deployed on EC2 instances using Amazon EBS volumes. The operations team has observed that when LaMa triggers a scale-in operation to remove an application server, the instance is terminated, but the associated EBS volumes (including the root volume) are not deleted, resulting in orphaned volumes and increasing storage costs. The team wants to ensure that EBS volumes are automatically deleted when an instance is terminated, especially during LaMa-driven operations. Which solution should the team implement?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Set the 'Delete on Termination' attribute to 'True' on all EBS volumes attached to the instance when it is launched by LaMa.

Option A is correct. When launching an instance, enabling the 'Delete on Termination' flag for the root volume ensures that the volume is deleted upon instance termination. For additional volumes, this flag must also be set. LaMa will then terminate the instance, and the volumes will be automatically deleted. Option B is incorrect because Lambda functions can be used but are more complex and may not be triggered by termination if the instance is the event source. Option C is incorrect because Lifecycle Manager is for scheduled snapshots, not for deletion on termination. Option D is incorrect because CloudTrail logs events but does not automatically delete volumes; it would require additional automation.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Configure an Amazon Data Lifecycle Manager (DLM) policy to delete volumes that are not attached to a running instance.

    Why it's wrong here

    DLM is for managing snapshots, not for deleting volumes based on attachment state.

  • Set the 'Delete on Termination' attribute to 'True' on all EBS volumes attached to the instance when it is launched by LaMa.

    Why this is correct

    With DeleteOnTermination enabled, when LaMa terminates the instance, the volumes are automatically deleted, preventing orphaned volumes.

    Related concept

    Static NAT maps one inside address to one outside address.

  • Create an AWS Lambda function that is triggered by EC2 instance termination events to delete unattached EBS volumes.

    Why it's wrong here

    This is a valid approach but less direct; it may have a delay and requires additional setup. Option A is simpler and more foolproof.

  • Use AWS CloudTrail to monitor TerminateInstances events and trigger an AWS Step Function workflow to delete the volumes.

    Why it's wrong here

    This is complex and reactive; enabling DeleteOnTermination is a proactive and reliable method.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Real-world example

How this comes up in practice

A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
