IAM Policy for Lambda Actions

This DVA-C02 practice question tests your understanding of development with aws services. 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.

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

Invoke the specified Lambda function and send messages to the SQS queue.

Option D is correct because the IAM policy grants permissions for `lambda:InvokeFunction` on a specific Lambda function (arn:aws:lambda:us-east-1:123456789012:function:MyFunction) and `sqs:SendMessage` on a specific SQS queue (arn:aws:sqs:us-east-1:123456789012:MyQueue). This means the Lambda function's execution role allows it to invoke only that particular Lambda function and send messages to that specific SQS queue.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • Invoke the specified Lambda function and receive messages from the SQS queue.

    Why it's wrong here

    Receive is not allowed.

  • Send messages to the SQS queue and invoke any Lambda function.

    Why it's wrong here

    Only the specific function is allowed.

  • Invoke the specified Lambda function and receive messages from the SQS queue.

    Why it's wrong here

    Receive is not allowed.

  • Invoke the specified Lambda function and send messages to the SQS queue.

    Why this is correct

    Both actions are explicitly allowed.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse 'send' vs. 'receive' permissions for SQS, or assume that a policy allowing invocation of one Lambda function implies permission to invoke any Lambda function, leading them to pick options that include sqs:ReceiveMessage or unconstrained invocation.

Detailed technical explanation

How to think about this question

Under the hood, AWS IAM evaluates actions against the resource ARN specified in the policy; here, the `lambda:InvokeFunction` action is scoped to a single function ARN, so any attempt to invoke a different function would fail with an AccessDeniedException. Similarly, the `sqs:SendMessage` action is scoped to a specific queue ARN, meaning the Lambda function cannot send messages to any other queue. In a real-world scenario, this granularity is critical for least-privilege security, such as when a Lambda function processes data and needs to trigger a downstream function or enqueue a message without exposing broader permissions.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

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

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
