200-301 Question 18
Single answerA small business is deploying a new wireless network using multiple access points (APs). The network administrator wants to ensure seamless roaming for users as they move between different APs in the building. Which configuration is required to achieve this?
- A
Configure the same SSID and security settings on all access points
- B
Assign unique SSIDs to each access point for better identification
- C
Enable DHCP on all access points to handle IP assignments locally
- D
Use different frequency bands (2.4 GHz and 5 GHz) on each access point
Show answer and explanation
Correct answer: A
Explanation
To enable seamless roaming, all access points must broadcast the same SSID with identical security settings. This allows client devices to automatically switch to the access point with the strongest signal without requiring user interaction. Other factors, such as signal overlap and channel planning, may also need to be considered, but the SSID and security configuration is a critical requirement.
- A. Correct.
Configuring the same SSID and security settings on all access points enables seamless roaming by allowing client devices to connect to the strongest signal without manual intervention.
- B. Incorrect.
Assigning unique SSIDs to each access point would require users to manually switch networks, which disrupts seamless roaming.
- C. Incorrect.
Enabling DHCP on all access points can cause IP conflicts and is not recommended. A centralized DHCP server should handle IP assignments in most cases.
- D. Incorrect.
Using different frequency bands can optimize network performance but does not ensure seamless roaming on its own.
