300-430 Question 87
Select 3A network administrator is deploying wireless multicast streaming on a Cisco wireless network using Multicast Direct. The administrator wants to ensure that the multicast traffic is efficiently delivered directly to clients without burdening the access points with replication tasks. Which of the following steps are required to implement Multicast Direct effectively in the wireless network?
- A
Enable Multicast Direct on the WLAN configuration.
- B
Configure the controller to operate in Multicast-Multicast mode.
- C
Ensure that Unicast to Multicast conversion is enabled on the controller.
- D
Verify that the client devices support IGMPv3 or later.
- E
Disable Multicast Group VLANs on the controller.
Show answer and explanation
Correct answers: A, B, D
Explanation
Multicast Direct allows multicast traffic to be sent directly from the controller to clients without burdening the access point with replication tasks, improving efficiency. To implement it, the administrator must enable Multicast Direct on the WLAN, configure the controller in Multicast-Multicast mode, and ensure client devices support IGMPv3 or later for proper group management. Other steps, such as unicast to multicast conversion or VLAN configuration, are unrelated or unnecessary for this feature.
- A. Correct.
Correct: Enabling Multicast Direct on the WLAN configuration allows the controller to send multicast traffic directly to clients instead of requiring the AP to replicate it.
- B. Correct.
Correct: Multicast-Multicast mode ensures that the controller forwards multicast traffic efficiently without converting it to unicast, which is critical for Multicast Direct.
- C. Incorrect.
Incorrect: Unicast to Multicast conversion is not relevant for Multicast Direct; in fact, this feature is used for other multicast scenarios, not direct delivery.
- D. Correct.
Correct: IGMPv3 or later is required because it supports advanced multicast group management and ensures that Multicast Direct operates properly.
- E. Incorrect.
Incorrect: Disabling Multicast Group VLANs is not a requirement for Multicast Direct implementation and could disrupt other multicast configurations.
