Designing Cisco Enterprise Networks (ENSLD) — Question 267

An architect is designing how the company will manage the infrastructure of a large data center. The company wants to group device types for security reasons and mitigate DoS attacks. The company also wants to ensure that access to the rest of the production network is not possible if one device is compromised on the management plane. Which solution must the architect choose?

Answer options

• A. out-of-band Ethernet
• B. out-of-band dial-up circuit
• C. in-band Ethernet
• D. in-band dial-up circuit

Correct answer: A

Explanation

The correct answer is A, out-of-band Ethernet, because it provides a separate management network that isolates management traffic from the production network, thus preventing a compromised device from accessing the rest of the network. Options B, C, and D do not provide the same level of isolation and security, making them unsuitable for the described requirements.
