This ANS-C01 practice question tests your understanding of network management and operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company is using AWS Client VPN to provide remote access to its VPC. Users report that they can connect but cannot access any resources. The VPN is configured with a security group that allows all traffic. What should the administrator check?
The client VPN security group inbound rules
Why wrong: Security group allows all traffic, so that is not the issue.
The client VPN endpoint certificate
Why wrong: If connection is established, certificate is valid.
The client VPN route table
Why wrong: Routes are typically automatically added; authorization rules are separate.
The client VPN authorization rules
Authorization rules define which networks clients can access.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The client VPN authorization rules
Client VPN uses an authorization rule to allow access to specific networks. Without an authorization rule, even if the security group allows traffic, the VPN will not forward traffic.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
The client VPN security group inbound rules
Why it's wrong here
Security group allows all traffic, so that is not the issue.
The client VPN endpoint certificate
Why it's wrong here
If connection is established, certificate is valid.
The client VPN route table
Why it's wrong here
Routes are typically automatically added; authorization rules are separate.
The client VPN authorization rules
Why this is correct
Authorization rules define which networks clients can access.
Related concept
Authentication checks who the user is.
Common exam traps
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
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
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related ANS-C01 questions on access control and AAA configuration.
