CCSP Practice Question: The effective permission for a request coming…
Exhibit
Refer to the exhibit. The following is an excerpt from a cloud provider's access control policy:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::example-bucket/*",
"Condition": {
"IpAddress": {
"aws:SourceIp": "10.0.0.0/8"
}
}
},
{
"Effect": "Deny",
"Action": "*",
"Resource": "*",
"Condition": {
"NotIpAddress": {
"aws:SourceIp": "10.0.0.0/8"
}
}
}
]
}What is the effective permission for a request coming from IP address 10.1.2.3?
⚠ Common exam trap
ISC2 often tests the misconception that an explicit allow for one action grants access to all actions, or that the absence of an explicit deny means full access, when in reality the default implicit deny restricts all other actions unless explicitly allowed.

Correct answer & explanation
✓
Access allowed only for GetObject
The effective permission for a request from IP 10.1.2.3 is 'Access allowed only for GetObject' because the bucket policy includes an explicit allow for the s3:GetObject action when the source IP matches 10.1.2.3, and no explicit deny applies to that IP. Since there is no explicit deny for this specific request, the explicit allow grants access only to the GetObject action, not to other actions like PutObject or DeleteObject.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Access allowed for all actions
Why it's wrong here
The allow statement only grants GetObject, not all actions.
- ✗
Access denied due to explicit deny
Why it's wrong here
The explicit deny uses a condition that does not match the request IP.
- ✓
Access allowed only for GetObject
Why this is correct
The request IP matches the allow condition, so GetObject is allowed; other actions are implicitly denied.
- ✗
Access denied because no explicit allow
Why it's wrong here
There is an explicit allow for GetObject from the allowed range.
