200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which THREE of the following are typically included in a Cisco DevNet sandbox environment? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Pre-configured Cisco devices (routers, switches, or firewalls)
Option C is correct because Cisco DevNet sandboxes provide pre-configured Cisco devices (routers, switches, firewalls) to allow developers to test automation scripts and network configurations without needing physical hardware. These sandboxes are isolated environments that mirror production-like setups, enabling safe experimentation with device APIs and CLI commands.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Ability to run production application traffic
Why it's wrong here
Sandboxes are isolated environments intended for development and testing, not production.
✗
Access to production customer data for realistic testing
Why it's wrong here
Sandboxes use synthetic or dummy data to avoid exposing real customer information.
✓
Pre-configured Cisco devices (routers, switches, or firewalls)
Why this is correct
Sandboxes typically include virtual or physical Cisco devices for testing.

✓
A sample network topology with an IP plan
Why this is correct
A predefined topology helps developers test network automation scripts.

✓
REST API endpoints for programmatic interaction
Why this is correct
DevNet sandboxes expose APIs to allow developers to automate and integrate.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between sandbox environments and production systems, and the trap here is that candidates mistakenly assume sandboxes include real customer data or can handle production traffic, when in fact they are strictly for development and testing with simulated resources.
Detailed technical explanation
How to think about this question
DevNet sandboxes leverage Cisco's DevNet platform to provide virtualized network topologies using technologies like Cisco Modeling Labs (CML) or virtual routers (e.g., IOSv, NX-OSv). These environments expose REST API endpoints (e.g., for Cisco DNA Center, Meraki, or ACI) that allow developers to practice programmatic interactions via HTTP methods (GET, POST, PUT, DELETE) and authentication mechanisms like API keys or OAuth2. The pre-configured topologies include IP addressing schemes and device configurations that simulate real-world network designs, enabling testing of automation scripts without risk of disrupting live networks.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
