200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 system administrator wants to use the Cisco Intersight API to collect hardware inventory from a set of UCS servers managed by Intersight. The administrator needs to retrieve the serial numbers, memory, and CPU information. The administrator has an API key with the appropriate permissions. The administrator uses a Python script with the requests library to send a GET request to https://intersight.com/api/v1/compute/PhysicalSummaries. The request returns HTTP 200 with a list of objects. However, each object only contains the 'Moid' and 'Name' fields; the serial number and hardware details are missing. What should the administrator do to get the full inventory details?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'Moid' from each summary object to send individual GET requests to /api/v1/compute/PhysicalSummaries/{Moid} for full details.
Option C is correct because the `/api/v1/compute/PhysicalSummaries` endpoint returns a list of summary objects containing only the 'Moid' and 'Name' fields by design. To retrieve the full hardware inventory details (serial numbers, memory, CPU), the administrator must use the 'Moid' from each summary object to send individual GET requests to the specific resource endpoint `/api/v1/compute/PhysicalSummaries/{Moid}`. This is a common RESTful API pattern where list endpoints provide lightweight summaries, and full details require fetching each resource individually.
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.
✗
Change the endpoint to /api/v1/compute/PhysicalSummary?details=true.
Why it's wrong here
The correct way is to query the specific instance; there is no 'details' query parameter.
✗
Add the '?expand=*' query parameter to the request to include all fields.
Why it's wrong here
Intersight API does not support 'expand' query parameter for this purpose.
✓
Use the 'Moid' from each summary object to send individual GET requests to /api/v1/compute/PhysicalSummaries/{Moid} for full details.
Why this is correct
This retrieves the full object with all fields, including serial number and hardware details.

✗
Generate a new API key with broader permissions.
Why it's wrong here
The existing key returned data, so permissions are likely sufficient.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that adding a query parameter like `?expand=*` or `?details=true` will magically include all fields in a list response, when in reality the correct approach is to fetch individual resources by their unique identifier (Moid).
Detailed technical explanation
How to think about this question
The Intersight API follows a RESTful resource-oriented design where collection endpoints (e.g., `/api/v1/compute/PhysicalSummaries`) return a paginated list of summary objects with minimal fields (typically 'Moid' and 'Name') to reduce payload size and improve performance. To access the full representation, the client must perform a GET request to the individual resource endpoint using the unique Moid (e.g., `/api/v1/compute/PhysicalSummaries/5e8d3f2a1b2c3d4e5f6a7b8c`), which returns all attributes including serial number, memory, and CPU details. This pattern is common in many Cisco APIs (e.g., DNA Center, Meraki) and aligns with REST best practices for efficient data retrieval.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
