200-301 Question 257
Select 3A network administrator is configuring a wireless LAN controller (WLC) for a corporate network. The administrator wants to ensure smooth video streaming for employees, restrict guest user access to certain VLANs, and secure the wireless network with WPA3 encryption. Which of the following actions should the administrator take to meet these requirements?
- A
Configure a QoS profile with video traffic set to 'Platinum' priority.
- B
Restrict guest user access by assigning them to a VLAN with limited network access.
- C
Enable WPA3 encryption on the wireless network settings.
- D
Disable QoS profiles to prioritize bandwidth for all traffic equally.
- E
Set the security mode to WEP for backward compatibility with older devices.
Show answer and explanation
Correct answers: A, B, C
Explanation
To meet the requirements, the administrator should ensure traffic prioritization through QoS profiles, secure guest access through VLAN segmentation, and use WPA3 for modern wireless security. Disabling QoS and using WEP are both counterproductive to the goals of performance and security.
- A. Correct.
Configuring a QoS profile with 'Platinum' priority ensures high priority is given to video traffic, which is essential for smooth video streaming.
- B. Correct.
Restricting guest user access to a VLAN with limited access enhances network security and ensures guests cannot interfere with sensitive corporate resources.
- C. Correct.
Enabling WPA3 encryption ensures the wireless network is protected with the latest and most secure encryption standards, meeting modern security requirements.
- D. Incorrect.
Disabling QoS profiles would negatively impact traffic prioritization, leading to poor video streaming and other quality issues.
- E. Incorrect.
Using WEP is highly insecure and outdated. It should never be used due to its vulnerabilities, even for backward compatibility.
