200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. 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.
Which two statements are true about Cisco DevNet Sandboxes?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DevNet Sandboxes include reserved labs for fixed time periods and always-on labs.
Option B is correct because DevNet Sandboxes offer two primary reservation models: reserved labs, which provide exclusive access to a sandbox for a fixed time period (e.g., 4 hours), and always-on labs, which are perpetually available but shared among users. This flexibility allows developers to choose between dedicated, time-limited environments for intensive testing and persistent, always-available environments for ongoing development and learning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
DevNet Sandboxes are only available with a paid subscription.
Why it's wrong here
Many sandboxes are free.
✓
DevNet Sandboxes include reserved labs for fixed time periods and always-on labs.
Why this is correct
Correct; both types exist.

✗
DevNet Sandboxes only support Cisco Catalyst switches.
Why it's wrong here
They support many platforms.
✓
DevNet Sandboxes provide API access to simulate integrations.
Why this is correct
Correct; they offer API endpoints.

✗
DevNet Sandboxes do not support third-party devices.
Why it's wrong here
Some include third-party devices.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume all sandboxes require payment or only support Cisco hardware, overlooking the free tier and the inclusion of third-party components like Linux VMs or partner APIs for realistic integration testing.
Detailed technical explanation
How to think about this question
Under the hood, DevNet Sandboxes leverage Cisco's infrastructure-as-a-service (IaaS) model, using virtualization and orchestration tools like VMware vSphere and Cisco UCS to provision isolated network topologies. For example, an always-on sandbox for Cisco DNA Center provides persistent REST API endpoints (e.g., /dna/intent/api/v1/network-device) that developers can call repeatedly without worrying about session timeouts, while reserved sandboxes dynamically allocate resources and tear them down after the reservation expires. This distinction is critical for CI/CD pipelines where consistent API behavior over time is required.
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.
