This 200-901 practice question tests your understanding of application deployment and security. 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 developer is writing a Python script to back up Cisco router configurations via SSH. Which two libraries are appropriate for this task? (Choose two.)
requests
Why wrong: Requests is used for HTTP APIs, not SSH.
netmiko
Netmiko simplifies SSH connections to network devices.
urllib
Why wrong: urllib is for URL handling, not SSH.
paramiko
Paramiko is a low-level SSH library that netmiko is built upon.
flask
Why wrong: Flask is a web framework, not for SSH.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
netmiko
Netmiko is a Python library built on top of Paramiko that simplifies SSH connections to network devices, including Cisco routers. It provides high-level methods for sending commands and retrieving output, making it ideal for automating configuration backups via SSH.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Cisco often tests the distinction between HTTP-focused libraries (requests, urllib) and SSH-focused libraries (paramiko, netmiko), trapping candidates who mistakenly think 'requests' can handle any network protocol or that Flask's 'networking' capabilities extend to SSH.
Detailed technical explanation
Netmiko extends Paramiko by adding device-specific drivers (e.g., cisco_ios, cisco_xr) that handle prompt detection, command timing, and output parsing. Under the hood, it uses Paramiko's SSHClient to establish encrypted sessions, then applies channel-level logic to send commands and read responses until the expected prompt is matched, which is critical for reliable backup scripts in production environments with varying network latencies.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
