The answer is that the termination will be denied because there is no explicit Allow for the TerminateInstances action. This occurs because the IAM policy deny EC2 termination with tag condition only triggers its Deny effect when the tag is NOT Production; since the instance is tagged Environment=Production, the condition is not met, so the Deny statement does not apply. However, the Allow statement in the policy does not include TerminateInstances, leaving the action subject to the default implicit Deny. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this tests your understanding of how IAM policy evaluation logic works—specifically that an explicit Deny overrides an Allow, but if a Deny’s condition is false, the policy engine falls back to checking for an explicit Allow; without one, the action is denied. A common trap is assuming the Deny’s condition block alone controls the outcome, but you must verify whether the Allow statement covers the action. Memory tip: “No Allow, no go—even if the Deny doesn’t show.”
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. 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.
The operations team uses the IAM policy above for a group of administrators. An administrator tries to terminate an EC2 instance that is tagged with Environment=Production. What will happen?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The termination will be denied because there is no explicit Allow for TerminateInstances
The Deny statement has a condition that denies termination only when the tag is NOT Production. Since the instance is tagged Production, the condition is not met, so the Deny does not apply. The Allow statement does not include TerminateInstances, so there is no explicit Allow for termination. The default is implicit Deny, so the action is denied.
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.
✗
The termination will be denied because the Deny condition applies to all instances
Why it's wrong here
The Deny condition explicitly excludes Production instances.
✗
The termination will be allowed because the Deny condition is not met
Why it's wrong here
The Deny condition not being met does not create an Allow.
✗
The termination will be allowed because the Deny does not apply to Production instances
Why it's wrong here
Even if Deny doesn't apply, there is no explicit Allow, so it is implicitly denied.
✓
The termination will be denied because there is no explicit Allow for TerminateInstances
Why this is correct
Without an explicit Allow, the action is implicitly denied.
Related concept
Static NAT maps one inside address to one outside address.
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.

What is the correct answer to this question?
The correct answer is: The termination will be denied because there is no explicit Allow for TerminateInstances — The Deny statement has a condition that denies termination only when the tag is NOT Production. Since the instance is tagged Production, the condition is not met, so the Deny does not apply. The Allow statement does not include TerminateInstances, so there is no explicit Allow for termination. The default is implicit Deny, so the action is denied.
