Question 408 of 512
Software Development ConceptsmediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that the policy denies delete access to the bucket for requests from the 192.0.2.0/24 IP range. This is because the policy explicitly sets the Effect to "Deny," the Action to "s3:DeleteObject," and the Resource to the bucket itself, while the Condition restricts this denial to traffic originating from the specified IP range. On the CompTIA ITF+ FC0-U61 exam, this type of question tests your ability to interpret AWS S3 bucket policy deny effect statements, often presented as a JSON snippet where you must identify which action is being blocked and under what condition. A common trap is confusing "Deny" with "Allow" or assuming the policy blocks all actions, but the key is to read each element: the Effect, Action, and Condition work together. Remember the memory tip: "Deny is a hard stop, not a soft permit"—if you see "Deny," the action is blocked, not allowed.

FC0-U61 Software Development Concepts Practice Question

This FC0-U61 practice question tests your understanding of software development concepts. 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.

Exhibit

Refer to the exhibit.

```json
{
  "effect": "Deny",

  "resource": "arn:aws:s3:::my-bucket/*",
  "condition": {
    "IpAddress": {
      "aws:SourceIp": "192.0.2.0/24"
    }

```

An administrator reviews the above policy. What does it do?

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

It denies delete access to the bucket for requests from the 192.0.2.0/24 IP range

The correct answer is B: It denies delete access to the bucket for requests coming from the 192.0.2.0/24 IP range. The effect is Deny, action is s3:DeleteObject, resource is my-bucket, condition restricts to IP range. Option A (allows delete) contradicts effect. Option C (denies all actions) is incorrect because only delete is specified. Option D (allows read) is wrong.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Answer analysis

Option-by-option breakdown

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

  • It denies delete access to the bucket for requests from the 192.0.2.0/24 IP range

    Why this is correct

    The policy explicitly denies s3:DeleteObject for the specified IP range.

    Related concept

    Standard ACLs match source addresses.

  • It allows delete access to the bucket for all IPs

    Why it's wrong here

    The effect is Deny, not Allow.

  • It allows read access to the bucket from the IP range

    Why it's wrong here

    The action is delete, not read.

  • It denies all s3 actions to the bucket

    Why it's wrong here

    Only s3:DeleteObject is denied.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Real-world example

How this comes up in practice

A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related FC0-U61 ACL questions on filtering logic and placement.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Based on the exhibit, what actions are permitted by this policy?

hard
  • A.GetObject and ListObjects
  • B.GetObject only
  • C.GetObject and DeleteObject
  • D.PutObject and GetObject

Why B: The policy has an Allow statement for s3:GetObject (read) and a Deny statement for s3:DeleteObject. Deny overrides Allow. No other actions are mentioned, so only GetObject is allowed. ListObjects is not explicitly allowed. PutObject is not mentioned.
