SAP-C02 Continuous Improvement for Existing Solutions Practice Question
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.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy all microservices from a single codebase.
Why it's wrong here
Monolithic deployments increase risk and reduce frequency.
- ✓
Implement blue/green deployments.
Why this is correct
Blue/green deployments reduce risk by switching traffic between environments.
- ✓
Use CI/CD pipelines with automated testing.
Why this is correct
Automation increases deployment frequency and reduces risk.
- ✗
Require manual approval for each production deployment.
Why it's wrong here
Manual gates reduce frequency.
- ✗
Use feature branches with manual merge approvals.
Why it's wrong here
Manual approvals slow down deployments.

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.
