The answer is establishing a secure shell session to an EC2 instance without using SSH keys and executing commands interactively on an EC2 instance. These two tasks are correct because AWS Systems Manager Session Manager provides agent-based, keyless access to instances through the AWS Systems Manager console or CLI, eliminating the need for bastion hosts or SSH key management. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of secure operational access for SAP workloads, where compliance often requires auditable, credential-free shell sessions. A common trap is confusing Session Manager with AWS Systems Manager Patch Manager or Parameter Store, which handle separate functions like patching and parameter storage. Remember the memory tip: “Session Manager is for shells and commands, not patches or parameters.”
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.
Which TWO tasks require the use of AWS Systems Manager Session Manager? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Execute a one-time command on an EC2 instance interactively
Options A and D are correct. Session Manager provides secure shell access without SSH keys (A) and can be used to execute commands interactively (D). Options B and C are wrong because Session Manager does not manage patches or store parameters. Option E is wrong because Session Manager is not for file transfers.
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.
✗
Transfer files between on-premises and AWS
Why it's wrong here
File transfers are not a primary function of Session Manager.
✓
Execute a one-time command on an EC2 instance interactively
Static NAT maps one inside address to one outside address.
✓
Establish a secure shell session to an EC2 instance without using SSH keys
Why this is correct
Session Manager enables secure shell access without SSH keys.
Related concept
Static NAT maps one inside address to one outside address.
✗
Store database connection strings securely
Why it's wrong here
Parameter Store is used for storing secrets.
✗
Apply operating system patches to a fleet of EC2 instances
Why it's wrong here
Patching is done by Patch Manager, not Session Manager.
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.
Operations and Maintenance — This question tests Operations and Maintenance — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Execute a one-time command on an EC2 instance interactively — Options A and D are correct. Session Manager provides secure shell access without SSH keys (A) and can be used to execute commands interactively (D). Options B and C are wrong because Session Manager does not manage patches or store parameters. Option E is wrong because Session Manager is not for file transfers.
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.
