The answer is none, because the explicit Deny statement overrides the Allow for all EC2 instances, including the one specified. This is due to the fundamental AWS IAM policy evaluation logic where an explicit Deny always takes precedence over any Allow, regardless of the resource scope. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of how IAM deny override allow for EC2 termination scenarios work, often appearing in questions that combine resource-level and condition-based policies. A common trap is assuming that a more specific Allow (like targeting a single instance ID) can bypass a broad Deny, but the rule is absolute: Deny wins. Remember the mnemonic “Deny Dominates”—once an explicit Deny is in effect, no Allow can reverse it, making the user unable to terminate any instance.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
None, because the Deny statement overrides the Allow for that instance
Option D is correct because the explicit Deny for all instances (*) overrides the Allow for the specific instance i-1234567890abcdef0, as Deny always wins. Option A is incorrect because the Deny applies to all instances. Option B is incorrect because the Deny covers all instances. Option C is incorrect because the Deny is explicit and overrides any Allow.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Only instance i-1234567890abcdef0
Why it's wrong here
The Deny is explicit and overrides the Allow for that instance.
✗
Any instance with tag 'Environment:Production'
Why it's wrong here
The Deny applies to all instances regardless of tags.
✓
None, because the Deny statement overrides the Allow for that instance
Why this is correct
Explicit Deny always wins over Allow.
Related concept
Static NAT maps one inside address to one outside address.
✗
Any instance in the account
Why it's wrong here
Deny on all instances prevents termination.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
