FC0-U71 File permissions Practice Question
Exhibit
Refer to the exhibit.
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::example-bucket"
},
{
"Effect": "Deny",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::example-bucket/*"
}
]
}
```A developer is troubleshooting an issue where a user can list the files in a shared folder but cannot download any of them. Based on the exhibit, what is the most likely cause?
⚠ Common exam trap
A common mix-up: candidates assume that having list permission implies full read access, but access control separates listing from reading file data, and an explicit deny on read overrides any allow.
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
✓
The Deny statement on read explicitly denies file retrieval.
The exhibit shows an explicit Deny statement for read access, which overrides any Allow statements due to access control evaluation logic. Even if the user has list permission, the Deny on read prevents downloading files. This is the most likely cause because Deny statements are absolute and cannot be overridden by Allow statements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user lacks permissions to list the folder.
Why it's wrong here
The user can list files, so they do have list permissions; the issue is with reading.
- ✗
The Allow statement on list also allows downloads.
Why it's wrong here
Allow statements for listing do not grant read access; they are separate permissions.
- ✓
The Deny statement on read explicitly denies file retrieval.
Why this is correct
Correct. An explicit Deny on read files prevents access, overriding any Allow.
- ✗
The policy is malformed and causes an error.
Why it's wrong here
There is no indication of a malformed policy; the exhibit shows a valid policy with a Deny.
