200-901 Infrastructure and Automation Practice Question
This 200-901 practice question tests your understanding of infrastructure and automation. 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.
A network automation engineer uses Terraform to manage Cisco Catalyst Center (formerly DNA Center) resources. What is the purpose of the Cisco Catalyst Center Terraform provider?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To define and manage network infrastructure resources in a declarative state file
Option D is correct because the Cisco Catalyst Center Terraform provider allows network automation engineers to define and manage network infrastructure resources in a declarative state file. Terraform uses a desired-state approach where the configuration file describes the intended end state of resources, and the provider communicates with Catalyst Center's REST API to enforce that state, enabling idempotent and version-controlled infrastructure management.
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.
✗
To execute a series of CLI commands on network devices in sequence
Why it's wrong here
Terraform is not a scripting tool; it manages resources through API calls.
✗
To write imperative scripts that configure network devices via SSH
Why it's wrong here
Terraform is declarative, not imperative; it uses providers to manage resources via APIs.
✓
To define and manage network infrastructure resources in a declarative state file

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Terraform's declarative, API-driven model with imperative scripting or CLI-based automation, leading them to select options that describe procedural SSH or CLI workflows instead of recognizing the provider's role as an abstraction layer over Catalyst Center's REST API.
Detailed technical explanation
How to think about this question
Under the hood, the Terraform provider for Cisco Catalyst Center translates HCL (HashiCorp Configuration Language) resource definitions into HTTP requests against Catalyst Center's REST API endpoints (e.g., /dna/intent/api/v1/network-device). The provider maintains a state file (terraform.tfstate) that tracks the current state of managed resources, enabling Terraform to compute a plan of changes before applying them. In a real-world scenario, this allows an engineer to define a campus network's site hierarchy, device credentials, and SSID configurations in code, then apply changes across hundreds of devices with a single terraform apply command, while ensuring compliance through version control.
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.
