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 two statements about the Cisco DevNet Sandbox are true?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sandboxes can be reserved for a fixed time period
Option C is correct because Cisco DevNet Sandboxes allow users to reserve a sandbox for a fixed time period, typically ranging from 2 to 4 hours, providing exclusive access to a pre-configured lab environment. This reservation model ensures that users have dedicated resources without contention, which is essential for testing APIs, automation scripts, or network configurations. The fixed-time reservation is a core feature of the DevNet Sandbox service, distinguishing it from always-on sandboxes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Sandboxes cannot be used for learning APIs
Why it's wrong here
They are designed for API learning.
✗
Sandboxes require a paid subscription for basic access
Why it's wrong here
Basic sandboxes are free.
✓
Sandboxes can be reserved for a fixed time period
Why this is correct
Many sandboxes require reservation.

Multiple platforms are supported.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between 'always-on' sandboxes (which provide persistent but limited access) and 'reserved' sandboxes (which offer full, time-limited access), and candidates may incorrectly assume all sandboxes require payment or only support a single OS.
Detailed technical explanation
How to think about this question
Under the hood, DevNet Sandboxes use virtualization and orchestration layers (e.g., VMware vCenter, Cisco Modeling Labs) to spin up isolated network topologies on demand. The reservation system enforces a lease-based model using a timer that automatically tears down the environment after the fixed period, preventing resource exhaustion. In a real-world scenario, a developer might reserve a DNA Center sandbox to test a Python script that automates device provisioning via RESTCONF, relying on the guaranteed uptime of the reservation to complete the task without interruption.
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.
