300-430 Question 90
Select 2A network administrator is configuring Multicast Direct on a Cisco wireless network to support a video streaming application that uses multicast traffic. The goal is to optimize performance by ensuring efficient delivery of multicast packets to wireless clients. Which of the following steps are required to successfully implement Multicast Direct?
- A
Enable multicast-multicast mode on the wireless LAN controller (WLC).
- B
Configure IGMP snooping on the wireless LAN controller (WLC).
- C
Enable Multicast Direct on the specific WLAN profile.
- D
Ensure clients support multicast-to-unicast conversion.
- E
Enable global multicast mode on the wireless LAN controller (WLC).
Show answer and explanation
Correct answers: C, E
Explanation
To implement Multicast Direct on a Cisco wireless network, it is essential to enable global multicast mode on the controller and enable Multicast Direct on the specific WLAN profile. These steps ensure the WLC can deliver multicast packets efficiently to wireless clients by converting them to unicast streams if necessary, optimizing performance and reducing unnecessary traffic overhead.
- A. Incorrect.
This option is incorrect because Multicast Direct does not require the multicast-multicast mode on the WLC. Instead, multicast-unicast conversion is used to optimize traffic delivery to wireless clients.
- B. Incorrect.
While IGMP snooping is beneficial for managing multicast traffic on the wired side of the network, it is not a specific requirement for enabling Multicast Direct on the WLC.
- C. Correct.
This option is correct because Multicast Direct needs to be explicitly enabled on the WLAN profile to allow wireless clients to receive multicast streams.
- D. Incorrect.
This option is incorrect because the wireless LAN controller handles multicast-to-unicast conversion, and client devices do not need to support this functionality explicitly.
- E. Correct.
This option is correct because enabling global multicast mode on the WLC is a prerequisite for implementing any multicast functionality, including Multicast Direct.
