300-420 Question 268
Select 2Your organization is designing a new enterprise network and must implement a management strategy for accessing network devices. Security and reliability are top priorities. The design team is debating between in-band and out-of-band (OOB) management. Which of the following are key benefits of using out-of-band management in this scenario?
- A
Out-of-band management provides access to network devices even if the production network is unavailable.
- B
Out-of-band management ensures higher bandwidth for management traffic by using the same network as user data traffic.
- C
Out-of-band management enhances security by isolating management traffic from production traffic.
- D
Out-of-band management eliminates the need for a dedicated physical management network.
- E
Out-of-band management reduces latency for configuration changes by sharing the production network.
Show answer and explanation
Correct answers: A, C
Explanation
Out-of-band management provides significant reliability and security advantages in enterprise networks by using a separate physical network or connection for management traffic. This ensures access to devices even during production network outages and isolates management traffic from user traffic, reducing the risk of unauthorized access or interference. However, it requires a dedicated management network, which adds to infrastructure complexity and cost.
- A. Correct.
This is correct because out-of-band management uses a separate physical connection or network, allowing access to devices even when the production network is down.
- B. Incorrect.
This is incorrect because out-of-band management does not share the same network as user data traffic, so it does not ensure higher bandwidth for management traffic.
- C. Correct.
This is correct because out-of-band management isolates management traffic, enhancing security by preventing exposure to the production network.
- D. Incorrect.
This is incorrect because out-of-band management typically requires a dedicated network or connection, not eliminating but rather introducing the need for a separate management network.
- E. Incorrect.
This is incorrect because out-of-band management does not share the production network, so it does not reduce latency for configuration changes in the production environment.
