This PAS-C01 practice question tests your understanding of migration. 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.
Refer to the exhibit. An administrator is creating an IAM policy for a user who will manage SAP application servers during migration. The policy currently allows starting and stopping EC2 instances. What additional permission is required to allow the user to terminate instances?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ec2:TerminateInstances
The action 'ec2:TerminateInstances' is needed to terminate instances. Option A (ec2:DeleteInstances) is not a valid action. Option C (ec2:ModifyInstanceAttribute) is unrelated. Option D (ec2:RebootInstances) is for reboot.
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.
✗
ec2:ModifyInstanceAttribute
Why it's wrong here
ModifyInstanceAttribute is for changing instance attributes, not termination.
✓
ec2:TerminateInstances
Why this is correct
TerminateInstances is the correct action for terminating EC2 instances.
Related concept
Static NAT maps one inside address to one outside address.
✗
ec2:RebootInstances
Why it's wrong here
RebootInstances is for rebooting, not termination.
✗
ec2:DeleteInstances
Why it's wrong here
There is no ec2:DeleteInstances action; termination is ec2:TerminateInstances.
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.
Migration — This question tests Migration — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: ec2:TerminateInstances — The action 'ec2:TerminateInstances' is needed to terminate instances. Option A (ec2:DeleteInstances) is not a valid action. Option C (ec2:ModifyInstanceAttribute) is unrelated. Option D (ec2:RebootInstances) is for reboot.
What should I do if I get this PAS-C01 question wrong?
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 key concept behind this question?
Static NAT maps one inside address to one outside address.
