A key principle to apply: ec2:RunInstances. 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.

  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "ec2:DescribeInstances",
        "ec2:StartInstances",
        "ec2:StopInstances",
        "ec2:DescribeVolumes",

    }
  ]
}
```

An AWS IAM policy is attached to a role used by an SAP migration tool (e.g., AWS Application Migration Service) for migrating an SAP system to AWS. The migration fails because the tool cannot create EC2 instances. What is the missing permission?

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

✓

ec2:RunInstances [CORRECT]

The policy likely allows actions like Describe, Start, Stop, and volume operations for existing resources, but it does not include 'ec2:RunInstances', which is required for the SAP migration tool to provision new EC2 instances for the target SAP system. Without this permission, the migration cannot proceed.

Key principle: ec2:RunInstances

Answer analysis

Option-by-option breakdown

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

  • ✗

    ec2:DescribeImages [wrong]

    Why it's wrong here

    'ec2:DescribeImages' allows listing AMIs, which is needed to select an image but does not create instances. Without 'ec2:RunInstances', the tool cannot launch instances.

  • ✓

    ec2:RunInstances [CORRECT]

    Why this is correct

    'ec2:RunInstances' is the permission required to create new EC2 instances. This is the missing permission for the SAP migration tool.

    Related concept

    ec2:RunInstances

  • ✗

    ec2:AllocateAddress [wrong]

    Why it's wrong here

    'ec2:AllocateAddress' is for assigning public IPs, not for creating instances. The migration fails before that step.

  • ✗

    ec2:CreateVolume [wrong]

    Why it's wrong here

    'ec2:CreateVolume' is used to create new EBS volumes. The migration tool may use existing volumes or create them, but the inability to create instances is the blocking issue.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

ec2:RunInstances

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
