- A
Deploy all microservices from a single codebase.
Why wrong: Monolithic deployments increase risk and reduce frequency.
- B
Implement blue/green deployments.
Blue/green deployments reduce risk by switching traffic between environments.
- C
Use CI/CD pipelines with automated testing.
Automation increases deployment frequency and reduces risk.
- D
Require manual approval for each production deployment.
Why wrong: Manual gates reduce frequency.
- E
Use feature branches with manual merge approvals.
Why wrong: Manual approvals slow down deployments.

SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 migrating a monolithic application to a microservices architecture on AWS. They want to improve deployment frequency and reduce risk. Which TWO strategies should they adopt?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement blue/green deployments.
Correct answers are B and C. Blue/green deployments (B) reduce risk by allowing instant rollback and minimizing downtime during production releases. CI/CD pipelines with automated testing (C) increase deployment frequency by automating build, test, and deployment steps, enabling rapid and reliable releases. Option A is incorrect because deploying all microservices from a single codebase increases coupling and blast radius. Option D is incorrect because manual approval gates slow down frequency. Option E is incorrect because feature branches with manual merge approvals introduce delays and integration complexity.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
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
How to think about this question
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.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
Visual reference
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SAP-C02 questions on access control and AAA configuration.
