ANS-C01 Network Implementation Practice Question

"Statement": [
{

"Action": [
"ec2:CreateVpc",

],
"Resource": "*"
},
{
"Effect": "Deny",
"Action": "ec2:CreateVpcPeeringConnection",
"Resource": "*"
}
]
}```Refer to the exhibit. A network engineer is creating an IAM policy for a junior engineer who needs to set up a VPC with public and private subnets and an internet gateway. The junior engineer reports that they cannot create a VPC peering connection. Based on the policy, what is the most likely reason?
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 policy has an explicit Deny statement for ec2:CreateVpcPeeringConnection.
The policy includes an explicit Deny statement for the ec2:CreateVpcPeeringConnection action. In IAM, an explicit Deny overrides any Allow, so even though the policy allows other VPC-related actions, the Deny prevents the junior engineer from creating VPC peering connections. Therefore, the most likely reason is that the policy has an explicit Deny for that action, which corresponds to option A. Option B is incorrect because the policy does allow ec2:CreateVpc and does not implicitly deny peering; an explicit Deny is required. Option C is irrelevant because the policy does not mention MFA. Option D is incorrect because the policy does not allow the action, but the explicit Deny is the stronger reason and is listed as option A.
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 policy has an explicit Deny statement for ec2:CreateVpcPeeringConnection.
Why this is correct
The explicit Deny overrides any Allow and prevents the action.
- ✗
The policy allows ec2:CreateVpc which implicitly denies peering.
Why it's wrong here
Implicit denies occur if action is not allowed; here it is explicitly denied.
- ✗
The policy requires multi-factor authentication to create VPC peering connections.
Why it's wrong here
The policy does not include a condition for MFA.
- ✗
The policy does not allow the ec2:CreateVpcPeeringConnection action.
Why it's wrong here
The policy explicitly denies it, not just missing allow; denies are explicit.
