The answer is AWS Systems Manager Session Manager, because it provides secure remote access for SAP administrators without exposing the instance to the internet. This service establishes an encrypted, audited shell connection through the AWS control plane, eliminating the need for bastion hosts or open SSH ports. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of secure remote access patterns for SAP workloads, specifically contrasting Session Manager against insecure public subnet SSH, site-to-site VPNs designed for network bridging rather than individual admin access, and Amazon WorkSpaces, which is a full virtual desktop solution, not a lightweight administration tool. A common trap is assuming a VPN is always required for remote admin, but Session Manager is purpose-built for this use case. Memory tip: think “no bastion, no public IP, just SSM” to recall that Session Manager replaces jump boxes for secure SAP administration.
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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.
An SAP system is running on AWS and needs to be accessible over the internet securely. Which AWS service should be used to provide secure remote access for administrators?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Systems Manager Session Manager
Option C is correct because AWS Systems Manager Session Manager allows secure shell access without bastion hosts. Option A is wrong because a public subnet with SSH from the internet is insecure. Option B is wrong because a VPN connection is for site-to-site, not remote admin. Option D is wrong because Amazon WorkSpaces is a virtual desktop, not a remote administration tool for SAP.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set up an AWS Site-to-Site VPN connection from the corporate network
Why it's wrong here
VPN is for network connectivity, not for remote admin access for individual administrators.
Use Amazon WorkSpaces to provide a virtual desktop for administrators
Why it's wrong here
WorkSpaces is for desktop virtualization, not for direct SAP system administration.
✗
Configure the EC2 instance in a public subnet with SSH access from the internet
Why it's wrong here
Direct internet access is insecure and against best practices.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
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 block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related PAS-C01 subnetting questions on CIDR, address ranges, and subnet selection.
