This DVA-C02 practice question tests your understanding of security. 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.
A developer is designing a microservices architecture where each service communicates over HTTPS. They need to ensure that only authorized services can invoke each other. Which TWO services can be used to manage authentication and authorization between services?
AWS App Mesh
Supports mTLS for service authentication.
AWS Resource Access Manager
Why wrong: RAM is for sharing resources across accounts, not service auth.
AWS VPC Lattice
Why wrong: VPC Lattice provides service-to-service auth, but the question asks for TWO, and we already have two.
AWS Direct Connect
Why wrong: Direct Connect is a network service.
Amazon API Gateway
Can use IAM authorization or Lambda authorizers for service auth.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS App Mesh
Option A and Option C are correct. AWS App Mesh provides service-to-service authentication using mTLS. AWS Resource Access Manager (RAM) is not correct. API Gateway can use IAM authorization or Lambda authorizers. VPC Lattice provides service-to-service authentication. AWS Direct Connect is for dedicated network connections.
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.
AWS App Mesh
Why this is correct
Supports mTLS for service authentication.
Related concept
Authentication checks who the user is.
AWS Resource Access Manager
Why it's wrong here
RAM is for sharing resources across accounts, not service auth.
AWS VPC Lattice
Why it's wrong here
VPC Lattice provides service-to-service auth, but the question asks for TWO, and we already have two.
AWS Direct Connect
Why it's wrong here
Direct Connect is a network service.
Amazon API Gateway
Why this is correct
Can use IAM authorization or Lambda authorizers for service auth.
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 DVA-C02 questions on access control and AAA configuration.
