This 350-401 practice question tests your understanding of 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.
Which THREE benefits does network automation provide over manual configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reduced risk of configuration errors
Option C is correct because network automation eliminates human error during repetitive configuration tasks. By using tools like Ansible, Python scripts, or NETCONF/YANG models, configurations are applied consistently without typos or missed commands, which are common in manual CLI entry. This directly reduces the risk of syntax errors, missing parameters, or inconsistent settings that can lead to network outages.
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.
✗
Increased security by eliminating the need for SSH access
Why it's wrong here
Automation often requires SSH; security depends on implementation.
✗
Lower initial investment compared to manual processes
Why it's wrong here
Automation often requires upfront investment in tools and training.
✓
Reduced risk of configuration errors
Why this is correct
Automation eliminates manual mistakes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that automation eliminates all manual access methods like SSH, but in reality, automation relies on SSH or similar transports for device communication, and the trap is assuming automation reduces security risks by removing SSH entirely.
Detailed technical explanation
How to think about this question
Under the hood, automation leverages model-driven programmability with YANG data models and protocols like NETCONF (RFC 6241) or RESTCONF (RFC 8040) to ensure idempotent configuration changes. In a real-world scenario, automating OSPF or BGP peer configurations across hundreds of routers ensures that every device receives the exact same parameters, avoiding neighbor mismatches that manual entry often causes. Subtle behaviors like rollback-on-error in NETCONF or Ansible's check mode further validate changes before deployment.

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.
