200-901 Question 142
Single answerA network engineer is tasked with validating a new network design for a large-scale deployment. The engineer needs to simulate the network behavior, test routing protocols, and evaluate the performance of the design under varying conditions without deploying physical equipment. Which tool or approach is most appropriate to achieve this goal?
- A
Cisco Modeling Labs (CML)
- B
Cisco DNA Center
- C
Cisco ThousandEyes
- D
Wireshark
Show answer and explanation
Correct answer: A
Explanation
The correct answer is 'Cisco Modeling Labs (CML)' because it is a purpose-built tool for simulating and testing network designs. It enables network engineers to create virtual topologies, test configurations, and validate protocols without requiring physical hardware. This makes it the most suitable choice for the given scenario.
- A. Correct.
Cisco Modeling Labs (CML) is specifically designed for network simulation and testing. It allows engineers to emulate complex networks, test configurations, and analyze protocol behavior in a controlled environment.
- B. Incorrect.
Cisco DNA Center is primarily focused on network automation, assurance, and management, not on detailed network simulation and testing.
- C. Incorrect.
Cisco ThousandEyes is a network performance and internet monitoring tool, used to identify and troubleshoot issues in real-world network environments but not for simulation or testing.
- D. Incorrect.
Wireshark is a packet capture and analysis tool, which is useful for network troubleshooting but does not provide network simulation or testing capabilities.
